retrospective

retrospective is a skill for Claude Code from joris887/exosuit. It costs 30 tokens per session (2,751 once invoked), scanned A, original, MIT.

A review of a sprint or weekly development period using project plans, progress records, metrics, and Git history. The 4Ls framework examines what people Liked, Learned, Lacked, and Longed for.

In plain words
What is it for?
It helps compare sprints, inspect leading and lagging measures, detect anti-patterns, and prepare a retrospective.
Why use it?
It turns scattered project records into a structured view of progress, trends, blockers, and recurring problems.

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 8d 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.

The opening of the file, as written. The whole thing — 260 lines — stays where its author put it; the contents beside it link to each section on GitHub.


retrospective

Run a sprint or weekly retrospective:

1. Gather Data

Read sprint specs and progress to build a complete picture:

  • Read docs/progress.md## Sprint History table for trend data
  • Read the sprint spec(s) being reviewed: docs/sprints/sprint-N.md — especially the ## Outcome and ## Decisions sections
  • Git log for commits and their messages
  • Any blockers or issues encountered (from sprint spec ## Notes and ## Decisions)

2. Metrics Dashboard

2.1. Progress Metrics (single source of truth)

Read docs/progress.md## Metrics table and display it directly — sprint-end already computed these values.

Metric Current Target Trend Status
[Copy all rows from progress.md Metrics table]

Sprint note: [Copy from progress.md if present]

2.2. Sprint-over-Sprint Comparison

Read docs/progress.md## Sprint History table. Extract the last 2 rows (current and previous sprint):

Metric This Sprint Previous Δ Direction
Goal achieved [✅/❌] [✅/❌] [streak]
Tasks completed [X] [Y] [+/-] [↑/↓/→]
Cycle time [X.Xd] [Y.Yd] [+/-] [↑/↓/→]
Change failure rate [X%] [Y%] [+/-] [↑/↓/→]
Test coverage Δ [+X%] [+Y%] [+/-] [↑/↓/→]
Code churn ratio [0.XX] [0.YY] [+/-] [↑/↓/→]
AI effectiveness [0.XX] [0.YY] [+/-] [↑/↓/→]
Sprint satisfaction [X/5] [Y/5] [+/-] [↑/↓/→]

Also extract from sprint spec (docs/sprints/sprint-N.md## Outcome):

  • Sprint churn: % stories added/removed mid-sprint (target <20%, >40% = broken planning)
  • Done-to-commit ratio: completed/planned (80% healthy, >95% = under-committing, <65% = over-committing)

2.3. Leading vs Lagging Analysis

Read references/metrics-analysis.md for the leading/lagging classification.

From the Sprint History's last 3 rows, assess the trend direction for each group:

  • Leading indicators (churn, coverage Δ, satisfaction): [improving / stable / degrading]
  • Lagging indicators (CFR, tasks): [improving / stable / degrading]

Changes

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.
