retrospect

retrospect is a command for Claude Code from GabsFranke/claude-code-github-agent. It costs 13 tokens per session (2,218 once invoked), scanned A, original, MIT.

A command that examines a session transcript and proposes improvements to an agent’s instructions through a pull request, a reviewable set of code changes.

In plain words
What is it for?
Use it after a session to identify instruction problems, suggest revisions, and submit those revisions for review in the develop branch.
Why use it?
It turns lessons from past work into tracked instruction updates instead of leaving them as informal notes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

retrospect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 26d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Retrospector

Analyse a completed agent session transcript, identify concrete problems with how the agent performed, and improve the instruction files that govern that agent's behaviour. Propose changes as a pull request to the develop branch.

Arguments: "$ARGUMENTS"

  • First argument: path to the session transcript summary (markdown, pre-processed)
  • Second argument: workflow name (e.g. review-pr, fix-ci, triage-issue, generic)
  • Third argument: target repository the session worked on (owner/repo, for context)
  • Fourth argument (optional): number of turns the session took
  • Fifth argument (optional): error if the session errored, otherwise omitted
  • Sixth argument (optional): subagent if this is a subagent session, otherwise omitted

Step 1 — Read the transcript summary

Read the transcript summary at the path given in the first argument.

The file is a structured markdown summary of the session, not the raw JSONL. It includes:

  • Total turn count and error count
  • List of subagents invoked (via Agent tool calls)
  • Timeline of assistant messages, tool calls, and tool results
  • Summary of all tool errors

Check the sixth argument to determine session type:

  • If sixth argument is subagent: This is a subagent execution session
  • Otherwise: This is a main workflow session

Agent Tool Landscape

When analyzing transcripts, you need to know what tools agents have access to so you can identify suboptimal tool usage. Agents in the sandbox have:

Search and exploration tools:

  • codegraph_search — Find symbols by name or pattern
  • codegraph_context — 360-degree view of a symbol's role and relationships
  • codegraph_callers / codegraph_callees — Trace how symbols are used across the codebase

File tools: Read, Grep, Glob, Write, Edit GitHub tools: mcp__github__* (PRs, issues, comments, reviews) Delegation tools: Agent (subagents), Skill (load knowledge) Skills: codebase-context (search system guide), git-worktree-workflow

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

retrospect is a command published in the GitHub repository GabsFranke/claude-code-github-agent (5 stars, last pushed 26d ago), licensed MIT. It adds 13 tokens to every session and 2,218 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
