retrospective

retrospective is a skill for Claude Code from voxpelli/claude-beads. It costs 91 tokens per session (5,005 once invoked), scanned A, original, MIT.

A method for writing a sprint retrospective: a record of what went well, what went wrong, decisions, and follow-up work after a development period.

In plain words
What is it for?
Use it to create numbered RETRO files, check project health, record decisions, and list follow-up tasks, including projects that use or do not use Beads for task tracking.
Why use it?
It gathers information from project notes, recent Git history, and the conversation so the review does not rely only on memory.

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

retrospective 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 10d 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 — 451 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sprint Retrospective

Generate a sprint retrospective for this project. If the project CLAUDE.md has a Sprint retrospectives section with a template, use it; otherwise use the template below.

Context

Retrospective files are named RETRO-NN.md in the project root. Each covers one sprint's worth of work.

Workflow

Beads availability

Beads is available iff a .beads/ directory exists and command -v bd succeeds; this component is Tier C per CLAUDE.md ### Beads-availability convention. Steps 1–3 and the UPSTREAM / SYNERGY / Basic Memory parts of the trend review are beads-independent and run unchanged. When beads is unavailable, the three bd-dependent steps degrade and announce (never skip silently):

  • Health audit (step 4) — replace the bd health checks with an announced skip line in the RETRO ### Health audit subsection (see step 4).
  • Findings (step 5) — append a ### Follow-ups (untracked) task list to the RETRO file instead of running bd create (see step 5).
  • Decision capture (step 5) — record decisions inline as a ### Decisions block in the RETRO file instead of bd create --type=decision (see step 5).

1. Determine sprint number

ls RETRO-*.md | sort -V | tail -1

Extract the highest sprint number and increment by 1.

This file count is canonical for the trend-review heuristic in step 4 — do not substitute a user-asserted topic number, release number, or bd sprint label. If RETRO-NN.md count is divisible by 4, this IS a trend-review sprint regardless of how the work is verbally framed.

2. Gather context

Run these in parallel:

Recent commits since last retro:

# Anchor to the commit that created/last modified the previous RETRO file.
# Edge cases that both result in full-history range (correct for Sprint 1):
#   1. No prior RETRO-*.md files exist yet
#   2. RETRO files are gitignored — git log -- RETRO-*.md returns empty
# In both cases the inner git log returns empty, making the range "..HEAD"
# which shows all commits — the right behavior for a first retrospective.
git log --oneline "$(git log -1 --format=%H -- RETRO-*.md)"..HEAD --no-merges

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.

retrospective is a skill published in the GitHub repository voxpelli/claude-beads (2 stars, last pushed 26d ago), licensed MIT. It adds 91 tokens to every session and 5,005 once invoked, about $0.0005 per session on Opus 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.
