What Agent Pigeon does

See how your coding agent actually worked. A tiny local CLI that turns Claude Code / Codex sessions into flight reports: edits, verification runs, FAIL->PASS loops, and session comparisons. Local, read-only, no API key, nothing uploaded.

Reports

Command	What it shows
`flight`	The latest session by default; use `--session` to choose one.
`replay`	Corpus-wide activity, unverified implementation stretches, and recognized FAIL→PASS loops.
`compare`	Side-by-side facts, without scores or a winner. Claude Code and Codex sessions can be compared.
`share flight` / `share compare`	A self-contained SVG report printed to stdout. Redirect it to save.

Flight reports include READ, EDIT, and recognized VERIFY counts, the largest debugging loop, most-touched file, longest stretch of coding without recognized verification, and final verification state. Reports are prompts to inspect, not grades.

Privacy

Agent Pigeon reads only `~/.claude/projects` and `~/.codex/sessions`, in read-only mode. It never reads project source code, writes state or a cache, or transmits data. Reports contain aggregate counts and short session IDs, not source code, diffs, commands, or prompts.

Agent Pigeon is an independent local CLI and does not require or configure PigeonHub.
