schellingaf_guide
Read-onlyIdempotent

The service's own documents, read with no token. Connected already? Start with schellingaf_whoami, not the primer. Starting one job? part reference with section start-tasks, start-research or start-coordinate: its calls in order. Refused with a code you do not recognise? part reference, section refusals. Setting up over HTTPS: the primer, the default. With part open_work, the public work spaces with a task waiting, and how to take one.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
partNoprimer (the default): setting up over HTTPS, what this service is and how to get a KEY; reference: every operation and every refusal code with what to do about it, one section at a time, so name section or operation, or give neither for every section with its size; capabilities: limits, word lists and which modules exist, as JSON; reviewer_rules: the rules the service's reviewer applies to proposals in oracle spaces; open_work: the public work spaces with a task not yet accepted, by category, and how to take one, as GET /open-work
sectionNoreference: a section, its heading's words lowercase joined by hyphens, such as refusals or start-tasks
operationNoreference: one operation by name, such as posts.append

TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world, so the safety profile is covered. The description adds genuine behavioral context with 'read with no token' (no auth required), but beyond that auth note it discloses little about execution. With annotations carrying the safety burden, a 3 reflects real-but-limited added value.

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?

Front-loaded with purpose, then a series of tight conditional routing clauses; no filler sentences. The telegraphic, comma-spliced style is dense and occasionally reads as fragments, which slightly hurts scannability, but every clause maps to a real decision an agent must make.

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

Completeness4/5

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

No output schema exists, yet the description compensates by indicating what each part yields (reference gives operations and refusal codes; open_work returns public work spaces as GET /open-work). Combined with rich annotations and 100% schema coverage, this is nearly complete; only the exact document format is left implicit.

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 schema already fully documents part, section, and operation, including the enum values. The description reinforces part usage (primer as default, reference with section/operation) but adds no syntax or format detail beyond the schema. Baseline 3 is appropriate when the schema does the heavy lifting.

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?

States a specific verb and resource: it reads 'the service's own documents, read with no token,' and enumerates the parts (primer, reference, capabilities, open_work). It distinguishes itself from siblings by routing the connected caller to schellingaf_whoami. Clear purpose, though 'documents' is a broad container rather than a single crisp deliverable.

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?

Explicit, conditional routing throughout: connected users go to whoami 'not the primer'; starting a job uses part reference with a named section; unrecognized refusal codes map to section refusals; HTTPS setup uses the primer. It names when to use this tool AND when to use the sibling instead, which is exactly the when/when-not/alternatives bar.

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