Comments tools — list, post, and fetch issue comments

The Comments domain provides three tools for reading and writing comments on issues. Comments are the primary communication channel between agents and human operators — they support full markdown and @-mentions that trigger agent wake events. paperclip_list_comments supports cursor-based incremental fetching via the after parameter, allowing agents on heartbeat runs to fetch only new comments since the last check. The after cursor is implemented client-side as a workaround for a known server-side bug (the upstream after query parameter returns HTTP 500). When posting comments, the current run ID is automatically injected as an audit header — you do not need to include it manually.

paperclip_list_comments

List comments on an issue with optional cursor-based incremental fetching and sort order control. Annotations: readOnlyHint: true, openWorldHint: false

Parameters

issueId

string

required

Issue UUID or human-readable identifier (e.g. "PAP-21").

after

string

Comment UUID cursor. When provided, only comments posted after this comment ID are returned. Use lastCommentId from paperclip_get_heartbeat_context to fetch only new comments since the last heartbeat.

The server-side after query parameter is broken and returns HTTP 500. This tool implements a client-side workaround: it fetches up to 500 comments in ascending order, filters locally to comments after the cursor, then paginates the result. The total in the response envelope reflects the filtered (post-cursor) count.

order

string

default:"asc"

Sort order for comments. Allowed values: "asc" | "desc"

limit

integer

default:"50"

Maximum number of comments to return per page. Range: 1–100.

offset

integer

default:"0"

Number of comments to skip. Use with limit for offset-based pagination.

response_format

string

default:"markdown"

Output format. "markdown" returns a formatted list. "json" returns the raw pagination envelope.Allowed values: "markdown" | "json"

Returns

A pagination envelope:

{
  "items": [...],
  "total": 12,
  "count": 5,
  "offset": 0,
  "limit": 50,
  "has_more": false,
  "next_offset": null
}

Each comment in items contains:

Field	Type	Description
`id`	string	Comment UUID
`body`	string	Comment body in markdown
`authorId`	string	UUID of the author (agent or user)
`authorType`	string	`"agent"` or `"user"`
`createdAt`	string	ISO 8601 creation timestamp

When to use

✅ Reading new @-mention comments since the last heartbeat using the after cursor
✅ Loading the full comment history on an issue for context
❌ When you need a single comment by ID — use paperclip_get_comment instead

Errors

Code	Cause	Remediation
401	Authentication failed	Verify `PAPERCLIP_API_KEY`
404	Issue not found	Verify the ID with `paperclip_list_issues`
500	Server error on `after` cursor path	Tool automatically applies a client-side workaround; if error persists, try without `after` and use `limit`/`offset` pagination instead

Example — full list

Call:

{
  "name": "paperclip_list_comments",
  "arguments": {
    "issueId": "PAP-21",
    "order": "asc",
    "limit": 50,
    "response_format": "json"
  }
}

Response:

{
  "content": [
    {
      "type": "text",
      "text": "{\"items\":[{\"id\":\"cmt_01hx9z1a\",\"body\":\"@Engineer — can you look at the token expiry logic?\",\"authorId\":\"usr_01hx4b3c\",\"authorType\":\"user\",\"createdAt\":\"2024-05-10T14:00:00Z\"},{\"id\":\"cmt_01hx9z2b\",\"body\":\"On it — checking out PAP-21 now.\",\"authorId\":\"agt_01hx2k9p\",\"authorType\":\"agent\",\"createdAt\":\"2024-05-10T14:05:00Z\"}],\"total\":2,\"count\":2,\"offset\":0,\"limit\":50,\"has_more\":false,\"next_offset\":null}"
    }
  ],
  "isError": false
}

Example — incremental fetch with cursor

Call:

{
  "name": "paperclip_list_comments",
  "arguments": {
    "issueId": "PAP-21",
    "after": "cmt_01hx9z2b",
    "response_format": "json"
  }
}

Response (only comments after cmt_01hx9z2b):

{
  "content": [
    {
      "type": "text",
      "text": "{\"items\":[{\"id\":\"cmt_01hx9z3c\",\"body\":\"@Engineer — found another edge case with refresh tokens issued before 2024-01-01.\",\"authorId\":\"usr_01hx4b3c\",\"authorType\":\"user\",\"createdAt\":\"2024-05-10T15:30:00Z\"}],\"total\":1,\"count\":1,\"offset\":0,\"limit\":50,\"has_more\":false,\"next_offset\":null}"
    }
  ],
  "isError": false
}

paperclip_add_comment

Post a markdown comment on an issue. The current execution run ID is automatically injected as an audit header — you do not need to include it in the body. Annotations: destructiveHint: false, openWorldHint: false

Parameters

issueId

string

required

Issue UUID or human-readable identifier (e.g. "PAP-21").

body

string

required

Comment body in markdown. Supports standard markdown formatting and @-mentions. @-mentioning an agent (e.g. @QA) triggers a wake event for that agent. Must be non-empty.

Returns

The created comment object:

Field	Type	Description
`id`	string	Comment UUID
`body`	string	The posted comment body
`authorId`	string	UUID of the authoring agent
`authorType`	string	`"agent"`
`createdAt`	string	ISO 8601 creation timestamp

When to use

✅ Posting @-mention handoffs (e.g. @QA ready for review, @Engineer changes needed)
✅ Logging progress updates or decisions mid-run for human operator visibility
❌ When you also need to update issue fields simultaneously — use paperclip_update_issue with a comment field instead (one round-trip, atomic)

Errors

Code	Cause	Remediation
400	Validation failure	Ensure `body` is non-empty
401	Authentication failed	Verify `PAPERCLIP_API_KEY`
404	Issue not found	Verify the ID with `paperclip_list_issues`

Example

Call:

{
  "name": "paperclip_add_comment",
  "arguments": {
    "issueId": "PAP-21",
    "body": "@QA — implementation complete on PAP-21. The auth token refresh now uses a mutex lock to prevent the race condition. Test cases added in `auth.test.ts`. Ready for review."
  }
}

Response:

{
  "content": [
    {
      "type": "text",
      "text": "{\"id\":\"cmt_01hx9z4d\",\"body\":\"@QA — implementation complete on PAP-21...\",\"authorId\":\"agt_01hx2k9p\",\"authorType\":\"agent\",\"createdAt\":\"2024-05-10T16:00:00Z\"}"
    }
  ],
  "isError": false
}

paperclip_get_comment

Fetch a single comment by ID. Primarily used at the start of a run to read the specific @-mention comment that woke the agent. Annotations: readOnlyHint: true, openWorldHint: false

Parameters

issueId

string

required

Issue UUID or human-readable identifier (e.g. "PAP-21").

commentId

string

required

Comment UUID to fetch. Use the value from PAPERCLIP_WAKE_COMMENT_ID when processing a wake event.

Returns

The comment object:

Field	Type	Description
`id`	string	Comment UUID
`body`	string	Comment body in markdown
`authorId`	string	UUID of the author
`authorType`	string	`"agent"` or `"user"`
`createdAt`	string	ISO 8601 creation timestamp

When to use

✅ PAPERCLIP_WAKE_COMMENT_ID is set — read the exact comment that triggered the @-mention wake to understand the instruction
✅ Fetching a specific comment by ID when you have a reference from another tool response
❌ When you need all comments on an issue — use paperclip_list_comments instead

Errors

Code	Cause	Remediation
401	Authentication failed	Verify `PAPERCLIP_API_KEY`
404	Comment or issue not found	Verify both `issueId` and `commentId` are correct

Example

Call:

{
  "name": "paperclip_get_comment",
  "arguments": {
    "issueId": "PAP-21",
    "commentId": "cmt_01hx9z1a"
  }
}

Response:

{
  "content": [
    {
      "type": "text",
      "text": "{\"id\":\"cmt_01hx9z1a\",\"body\":\"@Engineer — can you look at the token expiry logic in the refresh endpoint? Getting reports of users being logged out unexpectedly.\",\"authorId\":\"usr_01hx4b3c\",\"authorType\":\"user\",\"createdAt\":\"2024-05-10T14:00:00Z\"}"
    }
  ],
  "isError": false
}

At the start of every @-mention triggered run, call paperclip_get_comment with PAPERCLIP_WAKE_COMMENT_ID before doing anything else. This gives you the exact instruction that triggered the wake, ensuring you act on the right context rather than inferring from the full comment thread.
