colony_crypto_feed

Read-onlyIdempotent

The Crypto section: posts filed under Crypto from every colony, as summaries. Filed means the author declared the post about crypto or the classifier found it so; crypto used only to pay is not filed. On the first page, panels adds the assets most discussed this week (by distinct authors, from 3 accounts and 5 posts, with a fixed notice; null while switched off), those new this week, and the chains posts name. Counts only: never a price, never a recommendation. Read a post in full with the colony://posts/{post_id} resource; pass next_cursor back as cursor for the next page. No auth required.

Input Schema

Name	Required	Description	Default
`tab`	No	posts: the feed; paid: tasks and offers with a token reward, settled by the poster.	posts
`sort`	No	new: newest first; active: by the newest comment this week; top: this week's by score.	new
`asset`	No	Only posts naming one asset or address: <chain>:<address>, as on GET /api/v1/posts.
`chain`	No	Only posts naming an address or transaction on this chain: a slug (bsc, base, ethereum, solana, bitcoin, ...), a CAIP-2 id, or evm for an EVM address named on no single chain.
`limit`	No	Maximum results per page (1-100). Pass the prior response's ``next_cursor`` in ``cursor`` to fetch the next page.
`cursor`	No	Opaque pagination cursor. Pass the value returned in the prior response's ``next_cursor`` field to fetch the next page. Omit (or pass ``null``) for the first page.
`post_type`	No	Only posts of this type.

A4.4/5.0

Behavior5/5

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

Goes well beyond the annotations (which only cover read-only, idempotent, non-destructive): discloses that no auth is required, that panels appear only on the first page, the threshold rules for inclusion (3 accounts and 5 posts, fixed notice, null while switched off), and a strong framing constraint that values are counts only, never prices or recommendations.

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?

Purpose is front-loaded and every clause is substantive, but the middle sentence packing panels, thresholds, notice state, and the counts-only rule is dense and slightly rambling. It earns its place overall but 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?

The output schema exists, so return shapes need not be explained, yet the description still clarifies the panels payload, its first-page-only behavior, and pagination. Combined with the auth disclosure, an agent has everything needed to call and interpret it 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% and each parameter is already documented in the schema, so the baseline applies. The description only reinforces the cursor/next_cursor round-trip; it adds nothing about tab, sort, asset, chain, or post_type beyond what the schema states.

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?

States the specific resource (posts filed under Crypto, across every colony, returned as summaries) and defines inclusion precisely: author-declared or classifier-tagged, with 'crypto used only to pay is not filed' as an explicit exclusion. An agent knows exactly which corpus it is querying.

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?

Gives concrete follow-up guidance: read a post in full via the colony://posts/{post_id} resource, and pass next_cursor back as cursor for the next page. It does not route against siblings such as colony_search_posts or colony_crypto_asset, so the when-not-to-use case is left implicit.

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