Run milestone `/goal` blocks from `.docs/EXECUTION_PROMPTS.md` in dependency order, sequentially or in parallel when milestones are independent. Use when asked "run these milestone prompts", "execute EXECUTION_PROMPTS.md", "run the milestones sequentially", "run independent milestones in parallel", "orchestrate plan-prompts output", "continue the milestone sequence", "merge the stack", or "ensure CI is green and clean branches". NOT for generating plan files; use plan-prompts. NOT for repairing one existing stack; use stacked-prs.
Generate `.docs/DEVELOPMENT_PLAN.md` and `.docs/EXECUTION_PROMPTS.md` from system, design, architecture, or enhancement docs in a folder or explicit file list. Use when asked "create a development plan from docs", "generate execution prompts", "turn these design docs into milestones", "write DEVELOPMENT_PLAN.md and EXECUTION_PROMPTS.md", "plan implementation from .docs", "create milestone execution prompts", "convert architecture docs into stacked PR prompts", or when given DOCS_DIR / REPO_CONTEXT / GLOBAL_CONSTRAINTS / STACK_DEPTH_HINT placeholders. NOT for auditing an existing plan; use plan-review. NOT for executing the stack; use stacked-prs.
Senior codebase advisor that audits a repository, vets findings, and writes self-contained implementation plans for other agents to execute. Triggers on: "write improvement plans", "create an implementation backlog", "audit and plan fixes", "turn findings into plans", "agent-executable plans", "reconcile plans", "execute this plan", "what should we improve next". Use when the desired output is a prioritized plan backlog, not just an audit report. NOT for report-only quality gates; use codebase-auditor.
Create, review, and restyle data visualizations using Edward Tufte principles: high data-ink ratio, direct labels, range-frame axes, small multiples, accessible color, responsive charts, and honest comparisons. Triggers on: "create a chart", "style this chart", "review this graph", "Tufte chart", "data visualization", "Recharts", "Plotly", "matplotlib", "Chart.js", "ECharts", "D3". Use when generating or critiquing charts, dashboards, sparklines, and data tables.
Manages dependent branch stacks and stacked pull requests using safe Git topology rules. Triggers on: "create stacked PRs", "publish this stack", "sync my PR stack", "rebase this stack", "merge the stack", "retarget child PRs", "split this branch into stacked PRs", "validate this stack", "cleanup stacked branches". Use when local branches or one source branch need to become a dependency-ordered PR stack with correct parent bases, validation, synchronization, merge order, and cleanup.
Architecture reviews across 7 dimensions (structural, scalability, enterprise readiness, performance, security, ops, data) with scored reports. Triggers on: "review architecture", "critique design", "audit system", "assess scalability", "enterprise readiness", "technical due diligence". NOT for diagrams, use architecture-diagram.
Hypothesis-driven debugging with ranked hypotheses, git bisect strategy, instrumentation planning, and minimal reproduction design. Triggers on: "debug this systematically", "root cause analysis", "bisect this bug", "rank hypotheses", "isolate this issue", "minimal reproduction". NOT for general reasoning.
Scaffolds per-repository agent context so coding agents share the same issue tracker rules, triage label vocabulary, domain glossary, ADR layout, and handoff conventions. Triggers on: "set up project context", "configure agent docs", "create CONTEXT.md", "setup agent workflow", "agent issue tracker setup", "triage labels", "domain glossary for agents". Use when a repo needs durable context files before planning, triage, debugging, TDD, architecture review, or multi-agent implementation.
