agile-skills + 9arm-skills

agile-skills

Agent skills that run a software team through the Scrum loop — planning, design, build, verify, standup, review — in the same style as thananon/9arm-skills.

Each skill is a discipline, not a persona. There is no "backend developer" character to role-play. There is an implement discipline that builds test-first, a qa-verify discipline that tries to break the result, a sprint-planning discipline that refuses to plan from a vague one-liner. Claude loads the discipline the work needs and carries its constraints through the session.

Layout

Skills live under skills/, grouped into buckets:

• engineering/ — the delivery loop: plan, design, build, verify
• productivity/ — team rhythm and comms: standup, sprint review
• misc/ — kept around but rarely used
• personal/ — tied to a specific setup, not promoted
• in-progress/ — drafts not yet ready to ship
• deprecated/ — no longer used

Each skill is its own directory containing a SKILL.md (with YAML frontmatter — name and description) and any bundled scripts or reference files.

Install

With npx skills (recommended — works for every agent)

npx skills add <your-org>/agile-skills

Alternative — bash script

Symlink every shippable skill into ~/.claude/skills/:

./scripts/link-skills.sh

List every SKILL.md in the repo:

./scripts/list-skills.sh

Then, in a Claude Code session, run /agents-style discovery is not needed — skills trigger on their /command or proactively from their description.

Reference

Engineering

• sprint-planning — Turn a raw requirement into a disciplined backlog: INVEST stories, Given/When/Then acceptance criteria, points, one sprint goal. Refuses to plan from a vague one-liner.
• architecture-decision — Design before code: stack, module boundaries, the frontend/backend contract, and ADRs — with a mandatory "is there a simpler way" pass.
• implement — Build a story test-first against its acceptance criteria. Never claims done without a green suite; never silently changes an agreed contract.
• qa-verify — Adversarial, read-only verification against acceptance criteria. PASS/FAIL with reproducible evidence; finds, never fixes.

Productivity

• standup — Tight daily standup synthesised from git log, backlog, and QA report: done / doing / blocked, scannable in seconds.
• sprint-review — Close a sprint honestly: score shipped-vs-committed (QA-gated), then a blameless retro with owned, tracked action items.

Pairs with 9arm-skills

This package deliberately does not reimplement disciplines that thananon/9arm-skills already covers. Install both and they compose:

Need	Skill	From
Plan a sprint	sprint-planning	agile-skills
Design + ADRs	architecture-decision	agile-skills
Build a story	implement	agile-skills
Review a change	scrutinize	9arm-skills
Verify against criteria	qa-verify	agile-skills
Track down a defect	debug-mantra	9arm-skills
Write up a fixed bug	post-mortem	9arm-skills
Daily standup	standup	agile-skills
Close the sprint	sprint-review	agile-skills
Report up the org	management-talk	9arm-skills
