Add an Instagram account to the user's watchlist so its viral posts get detected automatically. Requires an active subscription and respects the plan's account limit.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is a mutating, non-idempotent operation, so the description adds value by explaining the subscription requirement, account limit enforcement, and the automatic viral-post detection behavior. This goes beyond what annotations alone convey.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
Two tightly packed sentences: the first states the core action and purpose, the second adds essential constraints. No filler or redundancy.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a single-parameter tool with no output schema, the description covers the action, the benefit, and the key prerequisites. It does not describe duplicate-account or limit-exceeded behavior, but that is not essential for basic invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, and the username parameter is already well described with 'with or without @' and 'profile URL' details. The description does not add additional parameter-level semantics, which is acceptable given the high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
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: 'Add an Instagram account to the user's watchlist'. It also states the intended effect ('so its viral posts get detected automatically'), which clearly distinguishes it from sibling tools like list_watchlist_accounts and remove_watchlist_account.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description conveys clear usage context by stating the prerequisite of an active subscription and the plan's account limit. It does not explicitly exclude alternative tools, but the action is unambiguous enough that an agent can infer when to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool has a distinct target resource/action, and the descriptions are unusually explicit about differences (e.g., 'Distinct from the watchlist', 'Separate list from list_tags'). A few pairs are still easy to confuse without careful reading: delete_folder vs delete_folders differ only by singular/plural, and the three download-URL tools (get_post_download_url, get_asset_download_url, get_my_account_post_download_url) plus the category/tag families require attention to pick correctly.
The snake_case verb_noun pattern is followed consistently throughout (list_*, get_*, create_*, update_*, delete_*, set_*, tag_*). Minor deviations: archive_folder and archive_my_accounts also perform restore despite their names, delete_folder/delete_folders split one operation by cardinality, and tag_posts/tag_my_account use a different verb style than the set_* family for metadata mutations.
At 56 tools, this far exceeds the 25+ threshold for 'too many,' even though the server spans multiple subdomains (watchlist, analysis, assignments, folders, my accounts, assets, Drive, categories/tags). Obvious consolidation candidates exist — delete_folder/delete_folders, the three download-URL getters, and the parallel list_my_account_* listers — and the sheer surface is heavy for an agent to navigate.
Core workflows are thoroughly covered with no dead ends: watchlist → analyze → assign → folder → track → approve has full lifecycle support, including reversible archive vs permanent delete choices. Minor gaps exist but are work-aroundable: no create/update for my accounts or models (app-side OAuth/admin only), no way to delete a viral post or a post note, and asset upload only happens in the app.
