SDLC Agent Toolkit
A compiler-backed, phase-gated SDLC framework for AI coding agents. These nine skills are the toolkit's compiled Claude Code output — one skill per lifecycle phase, from repository discovery through requirements, planning, implementation, testing, review, security, and documentation.
Skill
discover-repository-inspect
Map an unfamiliar repository into a cited orientation brief: stack, layout, build/test/lint commands, conventions. Use before planning or editing in a codebase not yet inspected this session.
Skill
requirements-feature-analyze
Turn a feature request into numbered requirements and acceptance criteria in traceability.yaml, with every ambiguity and assumption recorded. Use before planning or estimating an implementation.
Skill
plan-feature-implement
Produce the impact analysis and implementation plan for recorded requirements, tracing every task to an acceptance criterion, then stop for the approval gate. Use after requirements exist and before any edit.
Skill
develop-feature
Implement a feature end to end behind a human approval gate: inspect, specify, plan, approve, implement, test, review, summarize. Use when a change needs traceable requirements and a recorded approval.
Skill
develop-feature-execute
Implement the approved tasks and record which files each one produced. Use only after approvals.yaml carries an approved approve-implementation entry; never to start work the gate has not decided.
Skill
test-change-validate
Cover each acceptance criterion with a test, keep only tests that pass without decreasing coverage, and record every validation verdict including not_run. Use after implementation.
Skill
review-code-perform
Review a change set for correctness, performance and convention fit, emitting located findings with severity and confidence. Use after implementation and before requesting approval to merge.
Skill
security-change-review
Review a change for the security consequences a code review does not cover, emitting located findings with severity, confidence and an exploit path, filtered in two stages. Use after the code review.
Skill
document-change-summarize
Close a run with a summary whose every claim resolves to a recorded id: what changed, which requirements are satisfied, which tests ran, what risk and which degradations remain. Use as the last step.
