comment

Destructive

Comments on files: add/list/delete/react, anchor to image regions, A/V timestamps, PDF pages, or text selections. Call action='describe' for the full action/param reference. Destructive: delete, bulk-delete. Verbosity (detail param): list/list-all default to terse (compact rows). details defaults to full (drill-down). Pass an explicit detail='standard'|'full' to override (best-effort — may be a silent no-op until the comments API honors output=; see describe).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
sortNoSort: 'created' or '-created' (default newest first).
textNoMax 8192 body / 500 DISPLAY text (mention markup discounted) — the 500 usually BINDS. Both count CHARACTERS — CJK and emoji cost one each, same as ASCII. Mentions count toward 8192 only. A separate 2048-BYTE budget applies to the JSON-encoded `reference` anchor, where each non-ASCII character costs SIX bytes.
emojiNoSingle emoji character.
limitNoPage size 2-200.
actionYesOperation. Use 'describe' for full action reference.
detailNoPer-comment verbosity for list/list-all/details. Defaults: terse for list/list-all (compact rows), full for details (drill-down). See action='describe' for per-level field lists.
offsetNoOffset for pagination.
node_idNoStorage tree node opaque ID. Both files and folders are nodes — use this name regardless of which.
share_idNoAlias for profile_id when the profile is a share — implies profile_type=share (so profile_type may be omitted).
referenceNoAnchor: image region, A/V timestamp, PDF page, or text selection.
comment_idNoComment opaque ID.
context_idNoAlias for profile_id (either name works)
profile_idNoPolymorphic context ID (pair with profile_type=workspace|share). Typed aliases let you omit profile_type: workspace_id (⇒ workspace) / share_id (⇒ share); also context_id. 19-digit profile ID.
propertiesNoArbitrary key-value JSON object metadata (edit action only). Accepts a native object or a JSON string. Merged into the comment's stored properties; server-managed keys (reactions, version, version_hash, edited_at, content_filtered, mentions) supplied here are ignored.
comment_idsNoArray of comment opaque IDs.
context_typeNoAlias for profile_type (either name works)
profile_typeNoProfile type.
workspace_idNoAlias for profile_id when the profile is a workspace — implies profile_type=workspace (so profile_type may be omitted).
display_limitNolist-all only — ignored on the markdown list action. Number of comments to return to the agent (default 10, max 200). Backend page_size unchanged for cache warmth (JSON only). Trims post-fetch only.
include_totalNoInclude total count in response.
reference_typeNoFilter by anchor type.
include_deletedNoInclude soft-deleted.
parent_comment_idNoParent comment ID for reply (single-level threading).

TDQS

A4.2/5.0
Behavior4/5

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

Annotations already declare destructiveHint=true and readOnlyHint=false, and the description adds meaningful behavioral context: explicitly stating 'Destructive: delete, bulk-delete' and disclosing that the detail override is 'best-effort — may be a silent no-op until the comments API honors output='. This goes beyond the annotations but doesn't fully describe all behaviors, making 4 appropriate.

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 compact yet information-dense, covering purpose, action discovery, destructive behavior, and verbosity controls in just a few sentences. It is front-loaded with the main purpose and every sentence contributes, with no fluff or repetition.

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?

Given the tool's complexity (23 parameters, 10 actions, nested reference objects), the description does a good job by summarizing scope, pointing to action='describe' for full details, and covering key behavioral nuances. It doesn't explain return values or the full reference structure, but the schema and describe action compensate, so a 4 is fair.

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 coverage is 100%, so the baseline is 3. The description adds a small amount of parameter semantics via the verbosity discussion (detail defaults), but this is already present in the schema's detail parameter description. No significant new parameter meaning is introduced, so the baseline score stands.

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 the tool's purpose: 'Comments on files: add/list/delete/react' and explicitly mentions anchoring to image regions, A/V timestamps, PDF pages, or text selections. This specific verb+resource pairing distinguishes it from all sibling tools, none of which relate to comments.

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 clear usage context, such as calling action='describe' for the full reference and explaining verbosity defaults for list/list-all vs details. However, it does not explicitly mention when not to use this tool or compare it to alternatives, so it stops short of a 5.

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