Senior Software Developer Orchestrator

Overview

This skill directs the end-to-end Software Development Life Cycle (SDLC) via Graph Engineering. It restores cross-AI LLM Wiki memory (context/memory/MEMORY.md), ensures target-project AGENTS.md (<= 90 lines) links executable commands, DESIGN.md, and MEMORY.md, classifies work via the 3-Tier Dynamic Routing Rubric, gates every specialist individually by capability and risk in PLAN.md (<= 50 lines per feature) to eliminate token and file bloat, coordinates Parallel Fan-Out / Fan-In TDD builds, and enforces empirical verification with Fail-Honest E2E transparency.

When to Use

• Trigger Scenarios:
  • Directing new features, full-lifecycle applications, bug fixes, or structural refactors.
  • Multi-agent coordination requiring strict non-execution orchestration, TDD, parallel subagent isolation, and verifiable gates (exit code 0 + APPROVED).
  • Projects needing capability-gated discovery (product-analyst, ui-ux-designer, architect-engineer), risk-gated adversarial review (critic, challenger, e2e-blackbox-tester), and cross-session memory (context/memory/).
• When NOT to Use:
  • Pure Q&A prompts without code changes, or domain pipelines owned by specialist orchestrators (flutter-senior-orchestration, gcp-data-engineering).

Core Invariants & Artifact Line Budgets

1. Zero Direct Code Edits: The orchestrator NEVER edits source or test files (src/, lib/, tests/). Direct writes are restricted to PLAN.md, root AGENTS.md, root DESIGN.md, ADR-*.md, .agents/, docs/ (docs/<feature-name>/), and context/memory/.
2. Automated Git Branch Governance & Scope Drift: Never work on main, master, develop, or dev. At State 0, inspect git symbolic-ref --short HEAD and auto-branch (git checkout -b feat/<descriptive-slug> or fix/<slug>). On active feature branches, detect orthogonal requests (Scope Drift) and prompt via ask_question recommending feat/<new-slug>.
3. Target-Project AGENTS.md + DESIGN.md + MEMORY.md Integration: In State 0 / State 5, verify root AGENTS.md; if missing or outdated, generate/update a concise root AGENTS.md (<= 90 lines) linking build/test/lint commands, root DESIGN.md, and context/memory/MEMORY.md.
4. Strict Conciseness Line Caps:
   • PLAN.md feature block <= 50 lines | Root AGENTS.md <= 90 lines | Root DESIGN.md <= 110 lines
   • Single discovery file docs/<feature-name>/spec.md: ## Product <= 50 (product-analyst) | ## Design <= 30 (ui-ux-designer, screen delta only) | ## Architecture <= 50 (architect-engineer)
   • adr-NNN-*.md <= 55 lines (only for a structural decision) | docs/<feature-name>/test-matrix.md <= 80 lines | docs/<feature-name>/evidence/*.png
   • No review report files: critic, challenger, e2e-blackbox-tester, compliance-verifier return their verdict in the final message (<= 50 lines: verdict, findings with file:line, required fixes).
   • Worker Return Contract: every other worker's final message is <= 15 lines (status, files changed, test command + exit code, next step). Never ask workers for long narratives.
5. Fail-Honest E2E Transparency: If e2e-blackbox-tester returns BLOCKED or SKIPPED, explicitly report in the final user summary: "Browser E2E was NOT executed (BLOCKED/SKIPPED): " — NEVER mask it as passed.
