Diagnose or execute an explicit repository-wide maintainability cleanup while preserving behavior. Use only when the user asks to antislop a codebase, clean up an overgrown repository, plan or run a substantial structural migration, or audit maintainability across a repo. Do not trigger for ordinary feature refactors, a single large file, routine type improvements, adding regression tests, or broader production-readiness work.
Source documentation, not instructions for this website. Review permissions before running any commands.
Use this skill to reduce demonstrated maintenance cost while keeping current behavior essentially as-is. Do not impose a universal "product-shaped" architecture.
This skill is for demonstrated structural maintainability problems such as unclear ownership, harmful coupling, repeated logic, or repository-wide migration debt.
Do not expand the scope into a full production-readiness initiative. Observability/logging programs, security reviews, compliance, incident response, SLOs, runbooks, secrets posture, penetration testing, and deep reliability engineering belong in separate follow-on skills unless the user explicitly asks to include a small enabling change.
Run a quick non-mutating discovery pass before planning:
If the repo is live or user-facing, preserve compatibility for named live readers and keep changes reversible.
For deeper discovery prompts and commands, see analysis-checklist.md.
Produce a plan that can evolve, but is complete enough for another agent to execute:
Use request_user_input only for product tradeoffs that cannot be discovered from the repo.
Before broad edits:
Process the migration methodically:
If the user explicitly requests parallel work, assign independent surfaces and keep hot files single-owner.
For execution rules and worker prompts, see execution-playbook.md.
At each checkpoint:
Summarize the concrete maintenance cost reduced, changed structure, behavior preserved, checks run, deletions, and remaining costs. If the user explicitly requests a migration audit microsite, use audit-microsite.md.
A successful run reduces the named maintenance cost, preserves intended behavior, avoids speculative architecture and compatibility, and provides proportional evidence with honest residual risks.

Do not impose a universal "product-shaped" architecture. ## Boundary This skill is for demonstrated structural maintainability problems such as unclear ownership, harmful coupling, repeated logic, or repository-wide migration debt. Do not expand the scope into a full production-readiness initiative. Observability/logging programs, security reviews, compliance, incident response, SLOs, runbooks, secrets posture, penetration testing, and deep reliability engineering belong in separate follow-on skills unless the user explicitly asks to include a small enabling change. ## Operating Principles - Preserve behavior first. Improve architecture in thin, reversible slices. - Ground every decision in repo facts: file sizes, dependency graph, tests, runtime shape, API surfaces, user workflows, deployment limits, and current dirty worktree. - Prefer deletion and direct code over new layers. Add an abstraction only when it removes demonstrated duplication, isolates a volatile boundary, or clarifies ownership. - Treat file size, folder shape, type coverage, and test count as clues, not targets. A cohesive large file may be better than several pass-through modules. - Preserve compatibility only for a named live reader. Do not add barrels, facades, aliases, or migrations speculatively. - Never rewrite active user-owned areas without permission. If other agents/users are editing a surface, audit or work around it. - Use subagents, commits, deployments, screenshots, and audit artifacts only when the user requests them or the migration's scale clearly justifies them. ## Counterweight: stop before cleanup becomes architecture production - Scope the smallest set of hot paths that causes the reported maintenance pain. Do not clean adjacent code for consistency alone. - Name the concrete cost before changing structure: repeated defects, conflicting ownership, duplicated logic, unsafe coupling, or slow comprehension. - Reuse the repository's existing conventions unless they are the demonstrated problem. - Do not add feature folders, shared action layers, runtime schemas, tests, docs, or compatibility surfaces as a completeness checklist. - Do not turn a local refactor into a repository migration, productization program, release exercise, or audit presentation. - A concise diff and verification summary is the default finish. Produce a microsite only when explicitly requested. ## Workflow ### 1. Identify The Maintenance Cost Run a quick non-mutating discovery pass before planning: - Find only the entrypoints, callers, tests, and configuration relevant to the reported problem, plus current git status. - Measure size or dependency shape only when it helps test the maintenance hypothesis. - Identify user-critical workflows and constraints only insofar as they affect safe refactoring. - Read recent commits and docs to avoid undoing active work. If the repo is live or user-facing, preserve compatibility for named live readers and keep changes reversible. For deeper discovery prompts and commands, see [analysis-checklist.md](references/analysis-checklist.md). ### 2. Choose A Bounded Migration Produce a plan that can evolve, but is complete enough for another agent to execute: - Goal, success criteria, explicit non-goals, active no-touch areas, and risk posture. - Staged slices ordered by blast radius and verification confidence. - Public interfaces and compatibility promises. - Proportional verification for the changed behavior. - Concurrency and checkpoints only when the work is large enough to need them. Use `request_user_input` only for product tradeoffs that cannot be discovered from the repo. ### 3. Build The Baseline Safety Net Before broad edits: - Run the narrowest existing checks that establish a useful baseline. - If behavior cannot otherwise be preserved confidently, add the smallest high-value characterization test. - Add only minimal diagnostics or recoverable error handling needed to make the refactor safe; defer comprehensive logging/observability programs to a separate production-readiness skill. - Capture screenshots only for changed visual behavior that cannot be verified more cheaply. ### 4. Execute In Green Slices Process the migration methodically: - Change the highest-cost hot paths first; do not split files solely by line count. - Extract pure models/helpers before UI shells. - Convert untyped or ad hoc boundaries to shared domain types and runtime validation where API/provider data crosses a trust boundary. - Consolidate duplicated server/API functions only after response shapes are pinned by tests. - Migrate styling surface-by-surface; remove legacy selectors only after screenshot checks. - Keep each slice small enough to test, review, and revert. If the user explicitly requests parallel work, assign independent surfaces and keep hot files single-owner. For execution rules and worker prompts, see [execution-playbook.md](references/execution-playbook.md). ### 5. Validate Proportionally At each checkpoint: - Run the narrow tests for the touched surface. - Expand to broader checks only when shared boundaries or repository policy require it. - Run e2e/visual smoke before deploy when UI or production flows changed. - Preserve unrelated dirty user work. - Commit or deploy only when the active request includes those actions. ### 6. Report The Result Summarize the concrete maintenance cost reduced, changed structure, behavior preserved, checks run, deletions, and remaining costs. If the user explicitly requests a migration audit microsite, use [audit-microsite.md](references/audit-microsite.md). ## Quality Bar A successful run reduces the named maintenance cost, preserves intended behavior, avoids speculative architecture and compatibility, and provides proportional evidence with honest residual risks.
