Plugin Claude Code
Keystone proactive multi-skill AI engineering workflows for planning, implementation, review, shipping, and maintenance.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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…
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
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…
Skill Claude CodeCodex
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.
Skill Claude CodeCodex
Turn-by-turn guided learning tutor. Use when the user asks to learn/explain a concept OR when they continue an ongoing lesson (answering the last question, asking for hints, saying “next”, choosing a branch). Teach in small chunks, keep a visible lesson TODO checklist, include a simple visual when useful, then end…
