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

The annotations (readOnlyHint=false, destructiveHint=false) are present and align with the description. The description adds behavioral context beyond annotations, such as lease expiry, conflicting live claim returning 409, and the need to save execution_epoch and lease_expires_at. This makes the tool's behavior transparent and expected.

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?

The description is concise yet comprehensive, using structured sections 'USE WHEN', 'NOT FOR', and explicit behavioral notes. It avoids redundancy and packs essential information without being overly verbose. The structure enhances readability and preserves information density.

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?

The description covers all critical aspects: the action (claim/reclaim), when to use, what to save from the return, error handling (409 conflict), and the output (task payload). It also differentiates from related tools, ensuring the agent knows exactly when this tool is appropriate. The description is self-sufficient for safe and correct 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?

The only parameter, task_id, is fully described in the schema with 'Agent task UUID.' The description also hints at the return value containing execution_epoch and lease_expires_at, which provides additional semantic context. Since schema coverage is 100% and the description adds useful detail, parameter semantics are clear.

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 clearly states the tool's purpose: 'Claim an available Agent-stage task, or reclaim it after its lease expires.' It specifies the verb 'claim', the resource 'Agent-stage task', and additional nuance about reclaiming. It also distinguishes from sibling tools like talonic_get_agent_task and talonic_heartbeat_agent_task.

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?

Explicit usage guidance is provided: 'USE WHEN: ready to process a task' and 'NOT FOR: merely inspecting work (use talonic_get_agent_task) or extending an active lease (use talonic_heartbeat_agent_task)'. Behavioral details about conflicting claims (HTTP 409) and successful claims (returns task payload) further clarify when and how to use the tool.

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

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

Annotations already indicate non-read-only and non-destructive behavior. The description adds valuable context like cost ('cheap per call, free tier'), confidence-based review thresholds, and mentions of returned metadata. No contradictions with annotations.

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?

Given 11 parameters (0 required) with complex interdependencies, the description covers all document source options, schema definition methods, auto_schema, instructions, and optional output fields. It also describes the return structure with confidence scores and hints for handling low confidence. Output schema enriches this, but the description provides essential context for a complete picture.

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%, so the baseline is 3. The description adds meaning by explaining mutual exclusivity rules (schema vs schema_id vs auto_schema), recommending usage for each document source, and clarifying optional parameters like instructions and include_markdown. This is a meaningful addition beyond the schema.

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?

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

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety profile is covered. The description adds value by stating the data is immutable and audited, and mentions the timeout_fallthrough return field, which is non-annotated behavioral context. A small deduction because it doesn't elaborate on what timeout_fallthrough means or other edge cases.

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?

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

For a single-parameter read-based tool with rich annotations and 100% schema coverage, the description covers the purpose, usage, and return fields. The only gap is not explaining the 'timeout_fallthrough' field, but that's an output detail rather than a functional requirment. It doesn't need an output schema since it lists return keys.

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 covers task_id fully with format and description, so baseline is 3. The description just says 'ARGS: task_id' which adds no new semantics. That's acceptable given the schema's completeness.

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 clearly states the tool fetches an Agent-stage task's immutable input snapshot, instructions, and output contract. It names the specific resource ('Agent-stage task') and distinguishes it from siblings like claim/submit by explicitly naming those alternatives. The verb 'Fetch' is concrete and unambiguous.

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?

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?

Explicit conditions: 'USE WHEN: the user names or describes a document without an id... NOT FOR: structured field-value filters (use talonic_filter).' Also provides retry advice for empty results, which is actionable context.

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

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

The description adds meaningful behavioral context beyond the annotations: outputs are validated transactionally before anything is written, the execution epoch must come from a successful claim, stale epochs are rejected, and the document is resumed. This is strong for a write tool even though the annotations do not signal danger or contradiction.

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?

The description is compact, front-loaded with the core purpose, and organized with 'USE WHEN', 'NOT FOR', and 'ARGS' sections. Every sentence contributes actionable guidance with no wasted words.

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 tool with no output schema, the description covers the core workflow context: eligibility, arguments, validation behavior, contract enforcement, and resume semantics. It stops short of describing the response or potential failure modes after submission, but the key operational context is present.

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?

The input schema already documents all four parameters, so the baseline is 3. The description adds semantically valuable guidance by clarifying that outputs must be keyed exactly by the declared field key, that the optional summary is allowed, and that execution_epoch comes from a successful claim, which enriches the schema-only understanding.

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 clearly states a specific verb ('Submit') and resource ('declared output fields for a claimed Agent-stage task') and explains the resulting effect ('resume the parked document'). It also explicitly distinguishes itself from the sibling tool talonic_heartbeat_agent_task via the 'NOT FOR' clause.

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 provides explicit 'USE WHEN' and 'NOT FOR' guidance, stating this tool is appropriate when processing is complete and every required output is ready, and inappropriate for undeclared fields or partial maintenance. It even names the alternative tool, making the boundaries unambiguous.

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

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

Beyond annotations (readOnlyHint=false, destructiveHint=false, openWorldHint=true), description adds that file inputs ingest and consume credits while document_id does not, and different input methods have different costs.

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?

Well-structured with sections, front-loaded with main purpose. Every sentence adds value. No 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?

Given output schema exists, description covers return values (document_id and markdown). Addresses complex input choices and usage scenarios. Complete for tool complexity.

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% with good descriptions. Description adds hierarchy: prefer document_id, then file_url, then file_data+filename for small local files. Provides selection guidance beyond schema.

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?

Description clearly states it gets OCR-converted markdown text of a document. Uses verb 'Get' and specifies resource. Distinguishes from sibling talonic_extract for structured fields.

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?

Explicit sections: USE WHEN for full text/summarize/translate, NOT FOR structured fields, BY NAME instructs to first call talonic_search. Provides clear decision rules.

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