Transcript Grep

Find where a pattern appears in a session transcript and show the matches in context.

Input

The user provides: $ARGUMENTS

Interpreted as a session reference plus a search pattern, e.g.

<session-id> "rate limit" or latest TypeError. Parsing rules:

  • The session reference is the first token if it looks like an id, or the words

latest/last (most recently updated session).

  • The remainder is the search pattern (string or regex, quoted if it contains spaces).
  • If no session is given, default to the most recent session.

Data Sources

| Endpoint | Returns |

|----------|---------|

| GET /api/sessions?limit=N | session list to resolve latest/last and to confirm the id exists |

| GET /api/sessions/:id/transcript | the ordered transcript messages (role, content, tool calls/results, timestamps) for the session |

Report Sections

1. Resolve the session

If latest/last (or no id), call GET /api/sessions?limit=1. Otherwise verify

the id with GET /api/sessions?limit=1000 (or GET /api/sessions/:id). Report

the resolved id, status, and model before searching.

Call GET /api/sessions/:id/transcript. Walk the messages in order and match the

pattern against message text, tool_name, and tool input/output content.

Case-insensitive by default; treat the pattern as a regex if it contains regex

metacharacters, otherwise as a literal substring.

3. Matches with context

For each match show:

[#N  HH:MM:SS  role(:tool_name)]
  … preceding line of context …
> matching line with the **pattern** emphasized
  … following line of context …

Number matches sequentially. Include ±1–2 messages (or lines) of context so the

match is interpretable. If a tool call matches, show the tool_name and a trimmed

view of its arguments/result.

4. Summary

Report: total matches, how many distinct messages matched, the roles involved

(user / assistant / tool), and the timestamp span of the matches. If there are

zero matches, say so plainly and suggest a looser pattern.

Output

  • Lead with the match count and session header, then the contextual snippets.
  • Keep snippets trimmed — truncate long tool payloads with rather than dumping them.
  • Cite only transcript content returned by the API — never fabricate messages.
  • If the dashboard is unreachable, tell the user to start it with npm start from the repo root.

How to use it

Copy the folder

Take hoangsonww/transcript-grep from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
