sdlc

sdlc

Claude Code plugin: full SDLC pipeline for feature development. Replaces the legacy ~/.claude/agents/python-implementer.md, django-architect.md, and code-reviewer.md with 3 namespaced, distributable, stack-aware agents. Instead of duplicating TDD workflow and Functional Clarity principles, the plugin integrates with tdd-master and functional-clarity by reference — keeping each agent lean and the overall system DRY. Works as a standalone pipeline or as the execution layer under /plan-do from the planner plugin.

What it does

• sdlc:architect — designs systems: bounded contexts, data flow, contracts, hand-off documents. Model: opus. Never writes implementation code.
• sdlc:code-implementer — implements code per an architecture document using TDD (delegates to tdd-master:tdd-master for RED-GREEN-REFACTOR). Model: sonnet.
• sdlc:code-reviewer — reviews code changes for security (OWASP Top 10 always active), system issues, and FPF/Functional Clarity violations. Model: sonnet.
• Stack-aware references — backend-python, frontend-react, and api-design references load on demand per detected stack; skills degrade gracefully to universal principles for unknown stacks.
• TDD enforced — sdlc:code-implementer activates tdd-master:tdd-master before writing any production code (RED phase is mandatory).
• FPF principles enforced — functional-clarity:functional-clarity is referenced in both implementer and reviewer skills.
• Visual design — document-skills:frontend-design available for frontend deliverables via graceful integration.
• Orchestration-ready — all 3 agents are dispatched by /plan-do (from the planner plugin) in the architect → implementer → reviewer pipeline.

Installation

Add this marketplace to your Claude Code config and install the plugin from i-m-senior-developer:

/plugin marketplace add spumer/i-m-senior-developer
/plugin install sdlc@i-m-senior-developer

Migration from legacy agents

If you have legacy ~/.claude/agents/python-implementer.md, django-architect.md, or code-reviewer.md, follow these steps. Read all steps before running any rm command.

# 1. BACKUP first — check for local modifications you want to preserve
#    (custom triggers, project-specific tweaks, lessons-learned notes)
diff -q ~/.claude/agents/python-implementer.md /dev/null 2>&1 && \
  cp ~/.claude/agents/python-implementer.md ~/.claude/agents/python-implementer.md.backup
diff -q ~/.claude/agents/django-architect.md /dev/null 2>&1 && \
  cp ~/.claude/agents/django-architect.md ~/.claude/agents/django-architect.md.backup
diff -q ~/.claude/agents/code-reviewer.md /dev/null 2>&1 && \
  cp ~/.claude/agents/code-reviewer.md ~/.claude/agents/code-reviewer.md.backup

# 2. Install plugin from marketplace
#    (after publication: claude plugin install i-m-senior-developer/sdlc)

# 3. Remove legacy agents
rm -f ~/.claude/agents/python-implementer.md
rm -f ~/.claude/agents/django-architect.md
rm -f ~/.claude/agents/code-reviewer.md

# 4. Verify the namespace collision is resolved
#    `code-reviewer` exists as `sdlc:code-reviewer` after step 3.
#    Run `/help` and confirm the agents show `(plugin:sdlc)` label.

# 5. Update each project's planner-context.md §1
#    Option A (manual): replace rows for python-implementer / django-architect / code-reviewer
#                       with sdlc:architect / sdlc:code-implementer / sdlc:code-reviewer.
#    Option B (automatic): run `/plan-reflect` in a session with PLANNER_OUTPUT.md present
#                          — the planner-reflect skill detects the catalog change and
#                          appends auto-added rows. Manual-edit cells are preserved
#                          (per planner FEAT-0001 re-scan rules).

# 6. Smoke test
#    Run `/plan-do features/<any-feature>/README.md` — all 3 phases should dispatch
#    sdlc:architect → sdlc:code-implementer → sdlc:code-reviewer.

# 7. Cleanup backups (after verification — at least one full session)
rm -f ~/.claude/agents/*.backup

Sanity checks after migration:

• Confirm ~/.claude/agents/python-implementer.md is gone.
• Confirm ~/.claude/agents/django-architect.md is gone.
• Confirm ~/.claude/agents/code-reviewer.md is gone.
• Confirm /help shows (plugin:sdlc) label next to architect, code-implementer, code-reviewer.
• Confirm in any project's planner-context.md §1 the new rows exist (or the old rows are tagged <!-- stale, last seen YYYY-MM-DD --> after /plan-reflect).

Agents

Agent	Namespaced form	Model	Role
architect	sdlc:architect	opus	Designs systems: bounded contexts, data flow, contracts. Produces architecture documents. Never writes code.
code-implementer	sdlc:code-implementer	sonnet	Implements code per an architecture document. TDD-first via tdd-master:tdd-master.
code-reviewer	sdlc:code-reviewer	sonnet	Reviews code changes: security (OWASP always active), system issues, FPF violations. Never modifies code.

Skills

Skill	Activation triggers	On-demand references
sdlc:architect	"спроектируй", "архитектура", "design this feature", "как разбить модули", "где границы", README фичи + ARCH-документ нужен	references/backend-python.md (design angle), references/frontend-react.md (design angle), references/api-design.md
sdlc:code-implementer	"реализуй", "закодь", "implement this", "add the endpoint", ARCH/PLAN-документ готов	references/backend-python.md (implement angle), references/frontend-react.md (implement angle); always activates tdd-master:tdd-master
sdlc:code-reviewer	"отревью", "проверь код", "review this PR", "есть ли security-проблемы", после implementer-фазы	references/security.md (always active), references/backend-python.md (review angle), references/frontend-react.md (review angle)

Integration with other plugins

• tdd-master — sdlc:code-implementer activates tdd-master:tdd-master before writing any production code; the RED-GREEN-REFACTOR workflow is owned by tdd-master, not duplicated here.
• functional-clarity — sdlc:code-implementer and sdlc:code-reviewer reference functional-clarity:functional-clarity for FPF/Error Hiding checks and parsimony rules.
• planner — /plan-do (from planner) orchestrates the full pipeline: dispatches sdlc:architect → sdlc:code-implementer → sdlc:code-reviewer in sequence, loops until reviewer is clean.
• document-skills:frontend-design — graceful integration across the pipeline: sdlc:architect names the design system in the architecture document, sdlc:code-implementer activates it for visual quality during component implementation, sdlc:code-reviewer references it for visual/UX review of frontend changes. All three skills degrade gracefully when this plugin is not installed.

Examples

Architecture pass from a feature README:

/plan-do features/FEAT-0042-billing/README.md

→ /plan-do dispatches sdlc:architect first; it reads references/backend-python.md and references/api-design.md, emits features/FEAT-0042-billing/ARCH-01.md (architect's design output; the planner artefact PLANNER_OUTPUT.md is separate).

Backend implementation with TDD:

Архитектура готова (ARCH-01.md). Реализуй фичу.

→ Activates sdlc:code-implementer, which calls tdd-master:tdd-master for RED phase, then loads references/backend-python.md (ORM patterns, pytest fixtures, mypy config).

Security-focused code review:

Закончил имплементацию FEAT-0042. Отревью с акцентом на безопасность.

→ Activates sdlc:code-reviewer, which auto-loads references/security.md (OWASP Top 10) and references/backend-python.md (n+1, ORM pitfalls, transaction boundaries).

Requirements

• Claude Code with plugin marketplaces support.
• Recommended companions (sdlc works without them but with reduced features):
  • tdd-master — required for full RED-GREEN-REFACTOR in code-implementer.
  • functional-clarity — required for FPF/Error Hiding checks in code-implementer and code-reviewer.
  • planner — required for /plan-do pipeline orchestration.

Versioning

This plugin starts at 0.1.0. Any change to any file under plugins/sdlc/ — including skill references, agent wrappers, or this README — requires a semver bump in .claude-plugin/plugin.json per the repo CLAUDE.md rule. Use PATCH for fixes and prompt tweaks, MINOR for new agents/skills/references, MAJOR for breaking changes (removed agents, renamed skills, changed output format).
