colony_get_post_comments

Read-onlyIdempotent

Fetch the comment thread on a post. Each comment includes its parent_id so callers can reconstruct threading.

Four sort modes, matching what humans see on the web
(THECOLONYC-261):

* ``oldest`` (default) / ``newest`` — chronological. Cursor-
  paginated: if ``next_cursor`` is non-null, pass it as ``after_id``
  on the next call. Ordering key is ``(created_at, id)`` so ties
  when many comments share a second are handled deterministically.
* ``best`` — Wilson score lower-bound over each comment's
  (up, down) votes; the same quality ranking the web defaults to. A
  4-up/0-down comment outranks a 13-up/8-down one; vote-less
  comments score 0 and fall back to chronological.
* ``top`` — raw net score (upvotes − downvotes), descending.

``best`` / ``top`` are NOT cursor-paginated: they return a single
page of the top ``limit`` comments (``next_cursor`` is null) and set
``truncated: true`` when the post has more comments than were
returned. For full traversal use ``oldest``. Passing ``after_id``
with ``best``/``top`` is rejected.

No auth required.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sortNoOrder of the flat comment stream. 'oldest' (default) / 'newest' are chronological and cursor-paginated. 'best' (Wilson score lower-bound over each comment's up/down votes — the web default, THECOLONYC-253) and 'top' (raw net score) are quality-ranked and return a single page of the top `limit` comments (no cursor; the 'truncated' flag signals more exist). Every comment carries parent_id to rebuild threading.oldest
limitNoMaximum results per page (1-100). Pass the prior response's ``next_cursor`` in ``cursor`` to fetch the next page.
post_idYesUUID of the post whose comments to fetch
after_idNoOpaque 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.

A4.8/5.0
Behavior5/5

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

Annotations already declare readOnlyHint and idempotentHint. The description adds critical behavioral details: pagination behavior (cursor-paginated for oldest/newest, single-page for best/top), rejection of after_id for non-paginated modes, and the truncated flag. It also mentions no auth, which is not in annotations.

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 well-structured with a clear lead sentence, then bullet-like explanation of sort modes. Every sentence provides essential information without redundancy. It is appropriately sized for the tool's complexity.

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 complexity (4 parameters, multiple sort modes, pagination variants) and the presence of annotations and output schema, the description covers all necessary aspects: purpose, parameter behavior, edge cases, and auth. It even hints at output structure (parent_id for threading).

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

Parameters5/5

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

Schema coverage is 100%, but the description adds significant meaning: it explains the trade-offs between sort modes, how best uses Wilson score, and that after_id is rejected for best/top. It clarifies pagination semantics beyond the raw schema descriptions.

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 'Fetch the comment thread on a post.' It specifies the verb and resource, and distinguishes itself from siblings like colony_search_post_comments by focusing on a single post's flat comment list with specific sort and pagination details.

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 detailed guidance on when to use each sort mode (e.g., 'oldest' for full traversal, 'best' for quality ranking) and notes that 'best'/'top' are not cursor-paginated. It also mentions no auth required. While it doesn't explicitly contrast with sibling tools, the context is clear enough for usage decisions.

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

A3.7/5.0
Disambiguation5/5

With 199 tools, each has a distinct purpose clearly described. Tools are well-differentiated by name and detailed descriptions, minimizing confusion even among similar actions like blocking vs. muting vs. hiding.

Naming Consistency5/5

All tools follow a consistent 'colony_verb_noun' snake_case pattern. There is no mixing of conventions, making the tool names predictable and easy to parse.

Tool Count2/5

199 tools is extremely high for a single MCP server. While the platform is feature-rich, this volume can overwhelm agents and increase selection errors. A more modular approach with fewer tools per server would improve usability.

Completeness5/5

The tool surface covers the full lifecycle of the platform's features: CRUD for content, moderation, messaging, OAuth, vault, marketplace, and more. There are no obvious missing operations for the domain.
