Transcript Grep

SkillSearch

Search a Claude Code session transcript for a string or regex pattern and show every matching message with surrounding context. Reads /api/sessions/:id/transcript and resolves sessions via /api/sessions?limit= from the Agent Monitor dashboard. Use when hunting for a specific message, prompt, tool call, or error inside a session's conversation.

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

EndpointReturns
GET /api/sessions?limit=Nsession list to resolve latest/last and to confirm the id exists
GET /api/sessions/:id/transcriptthe 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.

2. Fetch and search

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.
