• linkedin_unsave_jobA
  3.8/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations supplied, the description carries the full burden of behavioral disclosure. It is exceptionally transparent: it confesses 'THIS TOOL CANNOT PERFORM ANYTHING TODAY,' explains the technical reason (unknown accessible name), details the preview failure condition, and states it will refuse rather than guess. This level of honest disclosure is exemplary.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness2/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is a multi-paragraph essay covering the tool's broken state, future fix, and preview behavior. While informative, it is verbose and could be condensed into a few sentences. An MCP description should be concise; this one isn't.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool has an output schema and no annotations, the description must convey behavioral context. It thoroughly covers why the tool refuses, how preview behaves, and the condition for it to work, leaving no ambiguity about what will happen when called. It is complete for an agent to handle correctly.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100% – both parameters (job_id and confirm_token) are fully described in the input schema, including the preview vs. token behavior. The description adds no additional parameter-level information, which is acceptable given the schema already covers semantics. Baseline 3 applies.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose4/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with 'Remove one job posting from your saved list,' which is a clear verb+resource statement. It implicitly differentiates from linkedin_save_job by being the inverse operation, though it doesn't explicitly compare with siblings. The core purpose is unambiguous despite the lengthy caveats about the tool being non-functional.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines3/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description implies usage when a user wants to unsave a job and explicitly states the tool cannot currently perform the action and will refuse until a label is measured. It also mentions the preview limitation based on having a saved job. However, it doesn't explicitly state when not to use it or mention alternatives, though the refusal condition is clear.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_saved_jobsA
  4.3/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations at all, the description carries the full disclosure burden and handles it well. It explicitly declares read-only behavior in both directions (covering what destructiveHint would normally signal) and gives a strong edge-case guarantee: an empty result is stated explicitly and carries LinkedIn's own count, so an empty list can never be misread as a failed call. This is the kind of behavioral detail agents genuinely need.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness3/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The opening line is profitably front-loaded, but the body is somewhat verbose for a single-parameter list tool and contains an internal inconsistency: the last sentence says 'this reads the two lists it names' when only one list (the Saved tab) is actually named. Phrases like 'when it was posted where LinkedIn shows it' are clunky. The redundancy around read-only scope could be tightened.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's simplicity (one optional parameter, no required inputs, an output schema present), the description is more than sufficient. It covers the safety profile, the exact scope, and the empty-result edge case, leaving no gap an agent needs to fill before calling it. The 'two lists' wording is a minor editorial slip, not a completeness failure.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The schema covers 100% of the single parameter (limit) with a complete description ('maximum rows to return (default 25, max 100)'). The tool description adds no parameter-level detail, which is acceptable since the schema already documents the limit fully and there are no other parameters to explain. Baseline 3 is appropriate.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The first line uses a specific verb and resource ('List the jobs you have bookmarked on LinkedIn') that clearly identifies this as the read counterpart to the save/unsave siblings. It names exactly what is returned (title, company, location, post date, link) and scopes itself to the Saved tab, distinguishing it from search and job-detail tools.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description states the tool reads only the Saved tab and explicitly notes that In Progress, Interview and Archived tabs are 'not exposed as tools.' The read-only framing ('no way to add to or remove from the list') implicitly routes agents away from linkedin_save_job/linkedin_unsave_job, though it does not name those alternatives directly or give an explicit when-to-use statement.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_my_applicationsA
  4.4/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  No annotations are provided, so the description carries the full burden. It discloses that status is whatever LinkedIn displays, that the server does not infer or chase, and explicitly explains edge cases: empty results carry LinkedIn's count, and a mismatch between rows and count yields an error. This is exceptionally transparent about behavior.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is multi-sentence and a bit longer than strictly needed, but every sentence adds value: scope, row contents, status behavior, and edge cases. It could be tightened slightly, but it is well-structured and front-loads the primary action.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The description explains row contents (title, company, location, status, how long ago, job id, link), clarifies that statuses mirror LinkedIn's display, and covers empty-result and error disambiguation. Given the simple schema and the presence of an output schema, this is complete enough for an agent to call correctly.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is 100% for the only parameter (limit), and the schema already documents its behavior fully. The description adds no further parameter details, so the baseline score of 3 is appropriate per the scoring rules.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description states exactly what the tool does: 'List the jobs you have applied to on LinkedIn, with their status.' It names a specific resource (own job tracker's Applied tab) and the action (list), and clarifies it reads only your own applications. This clearly distinguishes it from siblings like saved_jobs or search_jobs.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  While it doesn't explicitly name alternative tools or say when not to use it, the description makes the scope obvious: it reads only the Applied tab and cannot see applications made elsewhere. This is sufficient guidance for an agent to know when to invoke it versus other job-related tools.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_notificationsA
  4.4/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  Annotations are absent, so the description carries the full burden — and it delivers exceptionally. It discloses the badge-clearing side effect with a dated measured example (badge 1→0), states it is unavoidable, confirms this is the only server-side change in the package, and describes the partial compensation (unread flags captured at read time) plus input stripping behavior. This is model behavioral disclosure.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is long (~300 words), but the length is earned: the side-effect disclosure requires specific, verifiable detail. The purpose is front-loaded before the warning block, and the block formatting makes the critical information visually distinct. Minor deduction for verbosity in the compensation paragraph, which could be tightened.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a single-parameter list tool with full schema coverage, an output schema, and a thoroughly disclosed side-effect profile, nothing an agent needs to call it correctly is missing. Return format is described in prose (notification text, time, unread flag, link), complementing the output schema.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is 100% — the single 'limit' parameter (default 20, max 50) is fully documented in the schema. The description adds no parameter-specific meaning beyond the schema, which the rubric sets as the baseline 3. Nothing beyond the baseline, but nothing missing either.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The first sentence states a specific verb (List) and resource (your LinkedIn notifications) with a clear frame of reference ('as they appear on the notifications page'). It is unmistakably distinct from the sibling tools, all of which cover auth, sessions, jobs, or profile surfaces — no other tool claims the notifications surface.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description does not explicitly name an alternative, but none of the siblings overlap with notifications, so exclusion guidance is unnecessary. It instead provides strong context on when NOT to call: the side-effect block makes the cost explicit ('The only way not to clear the badge is not to call this tool'), which functions as clear usage guidance. Slight deduction for not naming an alternative, though no natural one exists.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_search_jobsA
  4.4/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full disclosure burden. It exceeds expectations by detailing that each call is a single page load with no scrolling or auto-paging, that results are roughly 25 per page, and that capped/page_had indicate row trimming. Most notably, it discloses a non-obvious side effect: searches are recorded in the user's own LinkedIn recent-search history, leaving a trace on the account. This level of transparency about side effects and pagination mechanics is exemplary.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is structured into three focused paragraphs: purpose, pagination mechanics, and privacy note. It is front-loaded with the core purpose in the first sentence. Every sentence contributes either operational details (single page, start offsets) or behavioral transparency (capped, page_had, search history). It is concise relative to the amount of critical information it conveys, though slightly longer than the bare minimum. The structure makes the key usage guidance easy to find.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a search tool with 8 parameters and an output schema, the description covers all necessary aspects: what the tool does, how it works, how to page for more results, what the returned fields include (title, company, location, job id, link), and the side effect on search history. The presence of an output schema means the return format needn't be detailed, and the description still names the key fields. Nothing essential is missing for an agent to call this correctly.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is 100%, so the baseline is 3. The description does not add significant meaning beyond the schema: it mentions start for paging and limit indirectly through the pagination discussion, but the schema already documents defaults, enums, and descriptions for every parameter (keywords, start, limit, remote, etc.). The description's pagination explanation adds marginal value over the schema's 'result offset for manual paging' line, but not enough to raise the score above baseline.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with a crisp statement of function: 'Search LinkedIn jobs with filters, returning one page of results.' It then specifics the returned fields (title, company, location, job id, link) and indicates the search runs on LinkedIn's own jobs page. This clearly distinguishes it from sibling tools like linkedin_job_detail (which likely retrieves a single job) and linkedin_saved_jobs (which lists saved jobs). The purpose is unambiguous and specific.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides explicit operational guidance: it explains the single-page behavior and instructs the agent to page deliberately using start=25, start=50, etc. It also explains the meaning of capped and page_had fields for interpreting results. However, it does not explicitly say 'use this instead of X' for any sibling tool, though the distinct search function is implied. The guidance is clear on how to use the tool for repeated paginated searches, which is the core usage pattern.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_who_viewed_meA
  4.4/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description takes full responsibility for behavior. It discloses that some viewers appear as anonymous with limited info, states the server makes no attempt to identify them and fetches nothing about viewers, mentions the data source (Premium analytics page), and explains the redirect behavior and resulting pages_loaded count. This is exceptionally transparent.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is longer than average, but it is front-loaded with the core purpose and organized into informative paragraphs. Each segment adds value: the high-intent context, anonymous viewer behavior, technical data source, and the redirect edge case. It is structured logically and avoids redundancy, though it could be tightened without losing clarity.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's simplicity (one parameter, no nested objects) and the presence of an output schema, the description still covers all essential behavioral context: the kind of rows returned (name, headline, when, link), anonymous flagging, the data source, and the redirect quirk. It even explains what the server does not do. This is complete for an agent to use correctly.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema description coverage is 100%, so the baseline is 3. The sole parameter 'limit' is already fully described in the schema with default and max values; the tool description adds no additional semantic meaning or usage nuance beyond that. Thus it meets the baseline without needing extra explanation.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with 'List the people who viewed your profile, most recent first' — a precise verb and resource. It clearly distinguishes from sibling tools like linkedin_search_jobs or linkedin_my_applications by specifying the unique action of listing profile viewers, and provides additional context about the 'highest-intent signal in a job search.'

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description provides strong contextual guidance on when this tool is valuable ('the highest-intent signal in a job search' and notes that anonymous viewers are often the most useful part), implying usage in recruiter outreach scenarios. However, it does not explicitly exclude or compare against sibling tools, so it falls short of a 5 but is above a 3 due to the clear situational context.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_job_detailA
  4.6/5.0
  Behavior4/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  There are no annotations provided (readOnlyHint, destructiveHint are absent), so the description carries the full burden of disclosing behavioral traits. It does this well: it states that this tool does not apply to the job, does not save it, and has no way to change anything about the posting; it also clarifies it does not collect other people on the page. It describes null vs. FAIL behavior for missing fields and unrenderable pages. The only small gap is that it doesn't explicitly mention auth requirements or rate limits, but for a read-only tool with one page load, the disclosure is thorough and covers the key side effects and failure modes.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is well-structured and front-loaded: the first sentence states the core purpose, then it builds context about what cards lack, confirms the one-page behavior, clarifies non-effects, and explains null/fail semantics. It is a bit longer than strictly necessary (around 150 words) but every paragraph earns its place by addressing a distinct aspect: what this gives, what it does not give, and the specific edge case. The structure is clear and uses paragraphs to separate logical blocks. Slightly verbose in places (repeats 'this does not apply...' phrasing), but overall effective.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the complexity is simple (one parameter, no nested objects) and there is an output schema (has_output_schema=true) that presumably describes the returned fields, the description covers the critical runtime behaviors an agent needs: what data is available, the distinction from sibling list tools, the null vs. FAIL semantics, and the explicit side-effect-free nature. The description fully equips an agent to decide when to call this tool and what to expect. The only potential missing detail is the exact output fields, but that is covered by the output schema, so the description is complete.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The schema has a single parameter, job_id, with 100% description coverage (the schema already describes it as the numeric job id or a job URL from two sibling tools). The description reinforces this by mentioning that both linkedin_search_jobs and linkedin_saved_jobs return it, but does not add new meaning beyond what the schema gives. Since coverage is 100% and the description adds a small hint about which tools return the id, a score of 4 is appropriate—slightly above baseline because the description confirms the source of the parameter value, which is useful for an agent.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with a direct, specific statement of what the tool does: 'Read one job posting in full, including the description and the pay.' It clearly identifies the resource (one job posting) and the verb (read). It goes further to distinguish itself from sibling list tools, explaining that this tool retrieves the full posting behind a card, and explicitly lists the facts available only here (pay range, applicant count, etc.). This fully separates it from the list/collection siblings (linkedin_search_jobs, linkedin_saved_jobs) and from action tools (linkedin_save_job, linkedin_unsave_job).

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description is explicit about when to use this tool vs. the sibling list tools: it explains that list tools return only cards with title, company, location, link, while this tool is where the decision-settling facts live. It states there is one page load, no pagination, and explicitly mentions it does not read the 'people also viewed' rail or hiring team. It also provides clear behavioral conditions: the call FAILS if the page did not render the posting, and it treats a title-only page as an error. This gives an agent unambiguous selection criteria.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_logoutA
  4.6/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full behavioral burden. It thoroughly discloses the destructive nature, the confirm-gated behavior (including that unconfirmed calls do nothing), the local-only scope (no remote impact), and the cross-process lock protection. It is transparent about irreversibility and side effects.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is lengthy but every paragraph serves a safety-critical purpose: purpose, consequences, confirm behavior, local-only scope, and lock protection. It is front-loaded with the core action, and structure is logical. While it could be trimmed, the verbosity is justified for a destructive tool.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's destructive complexity and absence of annotations, the description covers all essential aspects: the action, the confirm gate, preview behavior, irreversibility, recovery path, remote non-effect, and cross-process lock. The output schema exists separately, so return value details are not required here.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters3/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The input schema already provides a description for 'confirm' that exactly matches the text in the tool description ('False -- the default -- previews and performs nothing. True erases the jar.'). Since schema coverage is 100%, the description adds no additional semantic value beyond reiteration; the baseline of 3 applies.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with a specific verb and resource: 'End the local LinkedIn session by erasing this profile's cookie jar.' It clearly distinguishes itself as the sole destructive tool among siblings, making selection unambiguous.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  It explicitly warns that this is the one destructive tool and explains the cost of recovery, pointing to linkedin_login_browser as the alternative for re-establishing a session. The description implies when to use it (when you intend to end session) and strongly cautions against casual use, providing clear usage context.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_server_infoA
  4.6/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations, the description fully carries the burden. It discloses that version is a hand-maintained label while build.code.commit is measured and frozen at import, distinguishes between stale and current processes, explains how to compare against git rev-parse HEAD, and covers the dirty flag and started_at field. This goes well beyond what annotations would provide and gives the agent complete behavioral expectations.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is front-loaded with the main purpose and then dives into detailed interpretation of version/build fields. It is well-structured with a clear flow, but it is somewhat verbose, especially the code block and extended explanation of staleness. Every sentence adds value, so it is not padded, but it could be tightened without losing essential meaning.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The description is extraordinarily complete for a no-parameter tool. It explains the meaning of each output field (version, build.code.commit, dirty, started_at), how to interpret them together, and even provides a practical procedure (git rev-parse HEAD) for diagnosing stale servers. Nothing an agent needs to call or interpret this tool is missing.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The tool has zero parameters, so the schema is trivially complete (100% coverage). Per the rubric, a baseline of 4 applies, and the description adds no parameter detail (none is needed). No deduction is warranted.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with "Describe this server: what it can do, what it deliberately cannot," a specific verb/resource pair that clearly distinguishes this tool from siblings like linkedin_auth_status or linkedin_session_info. It states the exact scope (server capabilities, read-only boundary, rate settings) and the primary output (version and build information). No ambiguity about what this tool does.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  It explicitly states when to use it ("Useful for confirming the read-only boundary and the rate settings without reading the source"). It stops short of naming alternatives or explicit when-not-to-use conditions, but the context of the sibling list makes the intended use clear. A 5 would require an explicit comparison to alternatives, which is missing.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_session_infoA
  4.6/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations, the description carries the full burden and delivers heavily: it discloses the measurement method (identity endpoint, never cookie presence), the persistence of the session in an on-disk Chrome profile, the fallback to reading the jar without a browser and the resulting null 'authenticated', the fact that cookie values are never returned, and the semantic of renewal (silent_renew_available false, costs manual sign-in). This is extensive behavioral disclosure beyond the basics.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness2/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is extremely verbose. It includes narrative prose ('This is the question that comes up after a week away...'), extensive block-by-block explanations, and a meta-note about FastMCP cutting the docstring. While structured with headings, the length is excessive for an AI caller; many sentences could be trimmed without losing essential information. The front-loaded purpose is clear, but the overall bulk detracts from usability.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a tool with no annotations and a fairly complex behavior (fallback, multiple output fields, nuanced semantics), the description is extremely thorough. It explains each output block, the meaning of null, the reasons behind renewal limitations, and the durability of the session. An agent would have all necessary context to call it correctly, even without seeing the output schema (which exists but is not needed to understand the tool).

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The schema already covers the only parameter (verify_live) with a clear description, so the baseline is 3. The description adds value by explaining the trade-offs in context: it details what True vs False means for the live_check block, the fallback when no browser is available, and the null semantics. This enriches the parameter's meaning beyond the schema's concise text.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The opening sentence clearly states the tool's purpose: 'Report whether the session is live and how long it has left.' It goes further to differentiate from linkedin_auth_status by specifying that it uses the same identity-endpoint verdict but also includes the expiry date from the cookie jar, and it names linkedin_login_browser as the recovery path. This makes the resource and scope unambiguous.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description explicitly references alternatives and when to choose them: it says the verdict is the same as linkedin_auth_status, points out that linkedin_login_browser is the way back after lapse, and explains the fallback behavior when no browser can be started. It also tells when to set verify_live True vs False. This gives clear decision rules for an agent.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_auth_statusA
  4.7/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full burden and does so excellently. It discloses the internal behavior: makes up to two requests, uses the identity endpoint, treats cookies as unreliable, and explicitly defines the null case as 'unknown' rather than 'signed out'. This level of detail is transparent and goes well beyond basic expectations.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is structured with a clear opening statement, followed by detail and bullet-point outcomes. Every sentence adds value: it explains the measurement method, the meaning of each outcome, and the cost. It is thorough without being verbose, and the front-loaded core statement makes it easy to grasp quickly.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given that the tool has no parameters, an output schema exists, and the description thoroughly explains the semantics of each outcome, nothing is missing. It also covers edge cases (e.g., cookies from signed-out users) and costs, making it complete for an agent to use correctly.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The tool has zero parameters, so the description correctly does not discuss any. Per the calibration rules, a baseline of 4 is appropriate since there are no parameters to explain and the schema coverage is 100% (empty schema). The description doesn't need to add anything beyond that.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool's purpose: to report whether there is a live LinkedIn session, and it specifies the exact method (authenticated GET /voyager/api/me). It distinguishes itself from siblings like linkedin_session_info by emphasizing it measures actual authentication status, not guessed from cookies.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description effectively communicates when to use this tool—whenever an agent needs to determine authentication status. It explains the methodology and the three possible outcomes, making it obvious how to interpret results. However, it does not explicitly name alternative tools or state when not to use it, so it misses the highest bar for usage guidance.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_login_browserA
  4.7/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full burden — and it excels. It discloses that the server 'never sees, types, stores or transmits a password,' that the persistent Chrome profile retains the session, and crucially the non-obvious cookie nuance: 'A cookie appearing does not end the wait — it only causes the endpoint to be asked again.' It also states the no-optimistic-success guarantee on timeout. This prevents a common agent failure mode of assuming cookie presence means logged in.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is front-loaded with the purpose in the first sentence, and every subsequent sentence earns its place: the password privacy guarantee, the persistent-profile behavior, the termination conditions, and the cookie/timeout nuance. Nothing is filler; the multi-paragraph length is justified by the density of non-obvious behavioral information.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's interactive-browser complexity and the presence of an output schema, the description covers everything an agent needs: how the interactive flow works, the three termination conditions, the meaning of wait_seconds on timeout, and the return semantics. The one-time-step framing sets expectations correctly. Nothing essential is missing.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100% and the schema already documents wait_seconds with a default. The description adds value beyond the schema by tying the parameter to observable behavior: 'On timeout the result is authenticated false with a reason, never an optimistic success.' This connects the parameter to the wait-termination and result semantics, which is genuine value added over the schema text.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with a specific verb+resource+behavior: 'Open LinkedIn's sign-in page and wait for you to sign in yourself.' This clearly distinguishes it from siblings like linkedin_auth_status (checking status) and linkedin_session_info (session info). An agent immediately knows this tool initiates interactive login rather than inspecting or acting on the session.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description conveys the key usage fact that this is 'a one-time step until LinkedIn expires it,' which tells the agent not to expect repeated calls. However, it does not explicitly route to alternatives such as checking linkedin_auth_status first to determine whether login is even needed. The context is clear but lacks explicit when-not/alternative guidance.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_my_profileA
  4.7/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries full responsibility for behavioral disclosure. It is exceptionally transparent: it explains that LinkedIn defers certain sections until scrolling and that this server does not scroll, so those sections are usually absent and reported as UNKNOWN, not zero. It also admits the profile-strength meter is not exposed and that derived data is labelled as such.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is longer than average but every sentence adds information: it states the purpose, enumerates outputs, discloses limitations, and clarifies how to interpret absence. It is well-paragraphed and front-loads the core purpose before diving into nuance. No filler exists.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a read-only profile tool with an output schema, the description covers all necessary aspects: what is returned, the caveat about missing sections, how to interpret missing data, and a hint about the details_urls for further investigation. The 'include_skills' parameter behavior is also disclosed through the schema. Nothing an agent needs to call and interpret the tool correctly is omitted.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  There is a single parameter, include_skills, and its schema description is already very informative, explaining the effect (additional page load, pages_loaded: 2) and the trade-off. The description itself does not elaborate on the parameter, but because the schema coverage is 100% and the schema text is detailed, the parameter semantics are clear. A score of 4 reflects the extra value of the schema description beyond a bare type.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description uses a specific verb and resource ('Read your own LinkedIn profile') and immediately lists the concrete output fields (name, headline, location, About text, sections). It clearly distinguishes itself from siblings by focusing on the user's own profile and explicitly notes what is not included (profile-strength meter).

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines4/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description explains when the tool is appropriate (reading your own profile) and provides guidance on handling missing sections by pointing to details_urls. It does not explicitly contrast with sibling tools, but the tool name and the content give enough context for correct selection. The explanation of the 'include_skills' parameter also adds usage context.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_save_jobA
  4.8/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full burden of behavioral disclosure, and it excels: it states the tool mutates LinkedIn state, explains the preview/confirm two-step mechanism, describes the token's single-use, per-post, per-verb, two-minute expiry, and discloses that confirmation is read from a different surface (the saved list) rather than the button. It also explains the 'performed' result values and the risk of opposite actions on retry. This is exhaustive and transparent.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness4/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  The description is longer than typical, but it is well-structured and front-loaded: the opening sentence captures the core action and two-step nature. Subsequent paragraphs each add necessary detail (token lifecycle, confirmation source, retry warning) without redundancy. Every sentence serves a purpose; while verbose, it respects the complexity of the operation.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  Given the tool's state-changing complexity and two-step flow, the description is exceptionally complete. It covers the preview, confirmation, token expiry, result semantics, retry avoidance, and even a fallback suggestion ('look at your saved jobs instead'). An output schema exists, but the description still clarifies the meaning of 'performed' and the confirmation pathway, leaving no critical operational detail missing.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so the schema already documents both parameters. The description adds meaningful context for confirm_token—its lifecycle, the preview/confirm pattern, and that an empty value means preview—which goes beyond the schema. For job_id, it mostly repeats the schema's description but confirms it as a numeric ID. The added semantic depth for confirm_token raises the score above the baseline of 3.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description explicitly states the verb 'Bookmark' and the resource 'job posting on LinkedIn', and immediately distinguishes this tool from all read-only siblings by noting it is the only one that changes something on LinkedIn. It also implicitly contrasts with the sibling 'linkedin_unsave_job' by describing the save action. No ambiguity about what the tool does.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description gives a precise two-step procedure: call without confirm_token to preview, then call again with the token to save. It clearly states when to use the tool (when you want to save a job) and provides explicit warnings about token expiration, single-use, and when not to retry ('on "unknown" do not retry'). It also mentions the intended consequence of preventing unattended callers, further clarifying appropriate usage.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_cdp_statusA
  4.9/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool touches nothing on LinkedIn, only queries the local port, and reports the answer or the exact command to run when nothing answers. This fully discloses side effects (none) and expected outcomes, making behavior transparent and safe to invoke.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Although the description is relatively long, every sentence earns its place. It front-loads the purpose and the 'not the normal way' nuance, then details prerequisites and pitfalls, and finishes with the safety guarantee and output behavior. The structure is logical and efficient, with no filler.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The description is complete for a no-parameter diagnostic tool with an output schema. It explains the tool's role, when to use it, prerequisites, common failure modes, side effects, and how the result is reported. Nothing an agent needs to decide whether and how to call it is missing.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  The tool has zero parameters, and the schema confirms an empty object. The description does not need to explain parameters, and the baseline for no parameters is 4. It adds nothing beyond that, but nothing is needed—the schema already fully covers the parameter surface.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the tool's purpose: checking for an attachable browser, explicitly framing it as a recovery diagnostic. It distinguishes this from the normal persistent-Chrome-profile path and names the alternative clearly, so an agent can tell this tool apart from its siblings like linkedin_auth_status or linkedin_server_info.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description explicitly explains when to use this tool (when the profile session dies and automated sign-in is refused) and when not to use it (not the first choice, not the daily path). It also provides operational prerequisites (Chrome already running with --remote-debugging-port) and warns about the second-instance pitfall, giving concrete guidance that leaves no ambiguity.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_followed_companiesA
  4.9/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description fully carries the burden and does so excellently. It discloses the incomplete list due to scrolling, that 'complete' is normally false, and explains the three-valued semantics (UNKNOWN vs not followed) to avoid misinterpretation. It also notes the server's read-only nature.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Although long, every section earns its place. The critical caveat is front-loaded in a bolded warning, and the structure guides the reader from core purpose to alternatives. Nothing is redundant; it's dense but efficient.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  The description covers purpose, limitations, alternatives, and parameter usage thoroughly. Since an output schema exists to explain the return shape, nothing essential is missing. An agent can confidently decide when and how to use this tool.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Both parameters are already well-documented in the schema (100% coverage). The description adds a slight extra: 'Leave it out to get the whole rendered list' for the company parameter, which provides context beyond the schema. Given the high schema coverage, this is adequate but not extensive.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description clearly states the resource (company Pages you follow) and the action (list/read). It explicitly identifies itself as the counterpart of linkedin_saved_jobs and answers 'is this Page already on the list?', which precisely distinguishes it from mutation siblings like linkedin_unfollow_company.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  It explicitly names linkedin_job_detail as the better alternative for a single employer, explains why (reports company_follow_state directly from the posting page, never partial), and clarifies that this server cannot follow or unfollow anything. This gives clear when-to-use guidance and prevents misuse.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

• linkedin_unfollow_companyA
  4.9/5.0
  Behavior5/5

  Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

  With no annotations provided, the description carries the full burden and excels at it. It discloses the two-step confirmation flow, the lack of pagination in the followed-companies list and its consequences, the confirmation method (reloading the list and checking the total count drop), and the 'unknown' vs 'not followed' distinction. It even explains why a partial list makes absent rows unreliable evidence. This is exemplary behavioral disclosure.

  Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

  Conciseness5/5

  Is the description appropriately sized, front-loaded, and free of redundancy?

  Though long, the description is tightly structured and every sentence earns its place. The key warnings are front-loaded and emphasized with caps, and the paragraphs each address a distinct behavioral aspect. It is verbose only where necessary; the complexity of the tool justifies the length, and the structure makes it scannable.

  Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

  Completeness5/5

  Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

  For a tool with an output schema and non-trivial behavioral caveats, this description is complete. It covers prerequisites (get the ID), limitations (list is partial), verification (count drop), and side-effect asymmetry. Nothing an agent needs to call it correctly or interpret results is missing.

  Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

  Parameters4/5

  Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

  Schema coverage is 100%, so the parameters are already documented. The description adds contextual meaning: company_id is clarified as the numeric id printed by the followed list (not the name), and confirm_token is explained as the preview vs final confirmation flow, with an empty value meaning preview. This goes beyond the schema's basic 'leave empty to preview' by tying it into the overall two-step process, justifying a 4 over the baseline 3.

  Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

  Purpose5/5

  Does the description clearly state what the tool does and how it differs from similar tools?

  The description opens with a precise verb+resource ('Stop following one company Page') and immediately differentiates from siblings by referencing the shared two-step shape and five gates, and by naming the asymmetry with linkedin_follow_company. It leaves no ambiguity about what the tool does and how it differs from related tools.

  Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

  Usage Guidelines5/5

  Does the description explain when to use this tool, when not to, or what alternatives exist?

  The description gives explicit when-to-use guidance: call linkedin_followed_companies first to obtain the numeric ID, explains that names are refused, and details the list incompleteness that makes a 'unknown' verdict possible. It also states the asymmetry (can unfollow but not follow) and directs to the unimplemented follow tool for the inverse, leaving no room for misuse.

  Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
