retro

retro is a command for Claude Code from HigorAlves/orc. It costs 52 tokens per session (1,126 once invoked), scanned A, original, MIT.

A review of a coding session that looks for ways to improve the agent's working environment rather than the code itself. It can examine session files or transcripts and propose changes such as checks, coding rules, or better navigation.

In plain words
What is it for?
Use it after a difficult session to identify missing checks, unclear instructions, poor information access, or inefficient tool use.
Why use it?
It helps explain why a task was difficult or slow and turns those lessons into changes for future sessions. Accepted changes are applied in the repository, while other suggestions go through an issue tracker.

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

retro 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 2d 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/orc:retro

Look back at a coding session and improve the environment the next session runs in, not the code it produced.

A retro's output is a navigation pointer, a lint rule, a CI job, a coding standard, a slimmer steering file, a log the agent could not see. The code review already judged the code; this judges what made the code hard to get right.

Where it sits: the last step of the main flow (/orc:flow Phase 9 and /orc:debug offer it), and a standalone command after any session that went sideways.

Arguments

  • --session <branch> — look back at that .orc/<branch>/ session instead of the current one.
  • --transcript <path> — a session log on disk, read as a primary source once /clear has emptied the conversation.
  • --propose — run P1 then P5: calibration and candidate project-context rules.
  • <what to look back on> — free text narrowing the retro: "the three red slices", "why QA took 40 minutes".

Preconditions

🛑 Tracker writes

P4 files issues on the tracker. The preview gate before it is hard-outward: --auto never skips it.

⚠️ Caution

P4 commits applied candidates on the current feature branch, never on a protected branch.

  • A .orc/<branch>/ session is optional. Without one, say so and work from the conversation and git log alone.

Phases

Modules live in orc:phases (references/retro/). Entering a phase, Read exactly its module.

Phase Module Skipped when
0 Detect context resident, below never
1 Primary sources orc:retro/P1 never
2 Candidates orc:retro/P2 never
3 Present orc:retro/P3 never
4 Act orc:retro/P4 the P3 gate selects no candidate
5 Propose orc:retro/P5 no --propose

With --propose, run P1, then P5, and stop; P2 to P4 do not run.

Phase 0 — Detect context

  1. Resolve the session branch: --session <branch>, else git branch --show-current.
  2. If ${ORC_STATE_DIR}/<branch>/ is missing, note it for P1.
  3. Record --transcript <path> and the free-text focus, when given.
  4. Invoke orc:writing-for-agents.

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.

retro is a command published in the GitHub repository HigorAlves/orc (7 stars, last pushed 2d ago), licensed MIT. It adds 52 tokens to every session and 1,126 once invoked, about $0.0002 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 2026-10-21.

orchestrate

Do this task as an orchestrator. The aim is the same result at a fraction of the cost: in a long session, every token in this conversation is re-read on each later request, while a subagent's reading is discarded when it returns. The plugin's subagents run on Haiku 5.5, about 40× cheaper per token than Opus 5.5.
