sprint-retro is a skill for Claude Code, Codex from tomzx/agents. It costs 47 tokens per session (984 once invoked), scanned A, original, MIT.

A workflow for creating a sprint retrospective, a review of the last development cycle covering successes, problems, blockers, and follow-up actions.

In plain words
What is it for?
Use it to prepare a two-week retrospective with kudos, lessons, delivery blockers, and concrete action items.
Why use it?
It gathers evidence from notes, GitHub, and Slack so the team can identify improvements instead of relying on memory alone.

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

sprint-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 7d 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.

Generate Sprint Retrospective

Produces a structured sprint retrospective by reviewing the past two weeks of daily notes, GitHub activity, and Slack activity.

Prerequisites

  • Slack MCP server connected and authenticated
  • gh CLI authenticated
  • NOTES_DIR environment variable set (resolved via ~/.agents/scripts/get-env NOTES_DIR)
  • ~/.agents/scripts/get-env utility available
  • At least one week of daily notes present in {BASE_DIR}

Steps

1. Gather Data

  1. Resolve the notes directory:
    ~/.agents/scripts/get-env NOTES_DIR
    
  2. Read all daily note files from the past two weeks within {BASE_DIR} (.github.md, .slack.md, .overall.md, .timeline.md, weekly summaries).
  3. Fetch recent GitHub activity (PRs opened, reviewed, merged; issues closed) for the past two weeks using gh.
  4. Fetch recent Slack activity via the Slack MCP server for context on collaboration, blockers, and thanks.

2. Analyze and Categorize

Review all gathered data and categorize findings into the five retrospective sections below.

3. Write Retrospective

Write the output to {BASE_DIR}/{YEAR}/{MONTH}/{DAY}.sprint-retro.md using this template:

# Sprint Retrospective ({TODAY})

## Kudos
People who helped, collaborated well, or went above and beyond.
- **[Person]**: [What they did and why it mattered]

## Went Well
Things that worked effectively this sprint.
- [Item with brief supporting evidence]

## Could Have Gone Better
Things that did not go as smoothly as hoped.
- [Item with brief explanation of what happened]

## What Would I Have Needed to Move Faster This Sprint?
Blockers, missing context, tooling gaps, or process friction that slowed progress.
- [Item with specific suggestion if possible]

## Action Items
Concrete next steps to improve the next sprint, derived from the sections above.
- [ ] [Actionable item with owner if applicable]

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.
