sdlc

sdlc is a skill for Claude Code, Codex from dburkart/auto-engineer. It costs 37 tokens per session (968 once invoked), scanned B, original, BSD-3-Clause.

A software-delivery workflow for moving a code change from an idea to a merged pull request. It covers branches, commits, checks, pull requests, and responses to review feedback.

In plain words
What is it for?
Use it when starting a task, creating a branch, preparing commits, deciding which checks to run, opening or updating a pull request, or responding to review comments.
Why use it?
It gives developers a consistent process for making changes without committing directly to the main branch or losing track of review and testing requirements.

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 B, and why

sdlc scanned grade B with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SDLC

Read docs/agent-playbooks/sdlc.md first for repo-level branch, commit, push, and PR policy.

Read docs/agent-playbooks/pr-review.md when the task includes CI interpretation or review response.

When to use this skill

Use this skill when the task involves:

  • starting a new cohesive change on its own branch
  • deciding what checks to run before push
  • preparing a PR body and opening a PR
  • responding to review feedback without rewriting reviewed history

Branch naming

Create a branch per unit of work. Conventional patterns:

  • m<issue-number>-<slug> for issue-tracked work
  • <verb>-<noun> for untracked changes (e.g. fix-login-timeout, add-metrics-endpoint)

Always branch from an up-to-date main:

git checkout main && git pull
git checkout -b <branch>

Commits

  • Group related changes into coherent commits — not one mega-commit, not micro-commits per line.
  • Use the imperative mood in the subject line (Add, Fix, Remove, not Added, Fixed).
  • Each commit must include the trailer:
    Co-Authored-By: Claude Opus 4.6 <[email protected]>
    
  • Never commit directly to main.

Opening a PR

Use the standard Summary + Test plan body structure:

## Summary
- <bullet describing what changed and why>

## Test plan
- [ ] <concrete test step>
- [ ] <edge case to verify>

Closes #<N>

Open via mcp__github__create_pull_request. No "generated with Claude" footer.

CI and review follow-up

  • If CI or review follow-up is needed, hand off to wait-for-pr for Claude-specific polling and automation.
  • Review classification still comes from docs/agent-playbooks/pr-review.md.

Self-review (required for this project)

This project has no review bots or CI tests, so every PR must get an independent review before merge. Before requesting merge:

  1. Spawn a review subagent via the Agent tool with a prompt framing it as a Senior prompt engineer reviewing the diff for correctness, security, performance, and adherence to project conventions.
  2. Pass the agent the PR number and the full diff (gh pr diff <N>); instruct it to report blocking issues, in-scope nits, and out-of-scope suggestions separately, and to keep its reply under 400 words.
  3. Triage its findings using the same actionable/nit/out-of-scope classification above. Address blockers in a new commit on the branch; file follow-up issues for deferred items.
  4. Record in the PR body (under "Test plan") that a self-review was performed and link the resulting commits or issues.

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.
