Claude loads it when the task matches- change-review
Project change review for a concrete diff, branch, PR, patch, migration, fix, implementation result, or project plan that needs a new evidence-backed readiness verdict, or when another Keystone skill needs the Review Gate evaluated.
- context-survey
Project context survey for repository reconnaissance or project decisions that require evidence from existing code, project documentation, or project-specific external sources before planning or changing the project.
- implementation
Executable-software implementation in an identified software project for features, diagnosed fixes, migrations, integrations, and build or release automation. Select only when the requested change alters runtime, API, data, build, or release behavior and requires project-specific verification of integrated effects.
- product-planning
Software product planning for a concrete software or digital-product initiative whose behavior, UX, user-facing copy, technical direction, scope, or acceptance criteria must be shaped before implementation, or whose approved direction must become a specification.
- project-audit
Project health audit for a concrete software repository or product subsystem. Use when its tooling, CI, dependencies, configuration, tests, documentation, packaging, architecture, or agent instructions need a whole-system condition and risk assessment.
- refactoring
Program source-code refactoring for an explicit structural code improvement to structure, ownership, types, or duplication that preserves identified executable behavior. Select only when the request requires a structural code change with project-specific invariant proof, or enters through a canonical handoff from another Keystone skill.
- root-cause-analysis
Project debugging for a concrete failure in a software or product system. Use for a reproducible or evidence-bearing regression, failing test/build, runtime or integration defect, flake, data corruption, or performance anomaly, or when another Keystone skill needs the cause proven.
- shipping
Project shipping is authorized immediate delivery execution for identified, already-completed software work. Select only when the user explicitly authorizes an immediate concrete action to commit, push, prepare or create a PR, merge, tag, package, publish, release, deploy, perform an exact repository handoff, or perform destructive cleanup of an exact named completed-delivery target. A canonical handoff qualifies only when it carries the verbatim explicit delivery request and a non-empty exact authorized action set. Context Survey owns pre-authorization cleanup-target reconnaissance while approval is pending.
- task-creation
Project delivery breakdown for a concrete software or product goal. Use when that goal needs implementation slices, milestones, dependencies, verification gates, or agent-ready work, or when another Keystone skill hands off a shaped goal for sequencing.
