Compresses artifacts for judge evaluation. Reads a single raw artifact, applies tiered summarization within a token budget, and returns compacted content with metadata. Isolation via forked context prevents pollution of agent context

Skip Phase 7 rebuild when no code changed since Phase 5 build passed. Compares git diff hash against stored hash from last successful build validation. Triggers on: entering Phase 7, checking build status, before final build validation. Returns BUILD_CACHE_HIT to skip or BUILD_CACHE_MISS to re-run build-validator.

This skill should be used when working with Claude Code infrastructure including agents, skills, slash commands, hooks, plugins, settings.json, or CLAUDE.md files. Triggers on YAML frontmatter, .claude/ directory files, Task tool configuration, or hook debugging. Do NOT use for creating NEW skills from scratch - use claude-creator instead.

Provides ClosedLoop environment paths (CLOSEDLOOP_WORKDIR, CLAUDE_PLUGIN_ROOT) to agents. This skill should be used by any agent that needs to access ClosedLoop run directories, plugin schemas, or other path-dependent resources.

This skill should be used when designing prompts, system prompts, or context windows for Claude. Triggers include writing prompts for API calls, designing agent instructions, structuring complex inputs, optimizing context for accuracy, using examples effectively, or implementing chain-of-thought reasoning. Provides comprehensive guidance from Anthropic's official prompt engineering documentation.

Check if critic reviews are still valid before re-running Phase 2.5 critics. Compares plan.json + critic-gates.json content hash against stored hash from last critic run. Triggers on: entering Phase 2.5, checking critic cache, before launching critics. Returns CRITIC_CACHE_HIT to skip critics or CRITIC_CACHE_MISS to re-run them.

Use when the user wants a code-grounded decision table for current behavior, wants to compare current behavior against a plan or work item, or needs a control-flow artifact for recovery, retry, finalization, validation, state-machine, or review-heavy edge cases.

Check for a cached plan-evaluation.json result before launching the plan-evaluator agent. This skill should be used in Phase 1.3 (Simple Mode Evaluation) of the orchestrator prompt. Triggers on: entering Phase 1.3, checking simple mode, evaluating plan complexity. Returns EVAL_CACHE_HIT with cached values or EVAL_CACHE_MISS signaling re-evaluation is needed.

Sync plan.md with plan.json content. MUST be used after ANY edit to plan.json to keep plan.md in sync. Triggers: - After editing plan.json with Edit tool (REQUIRED - always sync after edits) - User asks to "sync plan.md", "update plan.md", "extract the md from a plan" - Converting plan.json to markdown or viewing plan as standalone markdown IMPORTANT: Whenever plan.json is modified, plan.md must be updated to match.

This skill should be used when needing to locate files within the Claude Code plugins cache directory (~/.claude/plugins/cache). Triggers include finding tool scripts, skill files, or any plugin resource when the hardcoded path is unknown or varies by plugin version. Use when slash commands or orchestrators need to dynamically resolve plugin file paths.

Structured format for capturing high-quality learnings during ClosedLoop runs

This skill should be used when a user asks to explain a complex idea, concept, or system architecture, or when a diagram would be helpful to visualize control flows, system architectures, data flows, state machines, sequence diagrams, or entity relationships.

Used when creating or updating implementation plans.

Deterministic plan.json validation via Python script, replacing most plan-validator agent calls. Performs JSON parsing, schema validation, task checkbox regex, required section checks, sync validation, and data extraction. Only semantic consistency checks (storage/query alignment) require the LLM agent. Triggers on: plan validation, checking plan format, extracting plan data. Returns PLAN_VALID with extracted data or PLAN_FORMAT_ISSUES with issues list.

This skill should be used when writing or parsing TOON (Token-Oriented Object Notation) files. Triggers on .toon file operations, org-patterns.toon generation, or when converting between JSON and TOON formats. Provides syntax rules, quoting conventions, and examples for LLM-optimized data serialization.

Upload a file as a ClosedLoop artifact (PRD, implementation plan, or template). Reads file content and uploads via MCP without consuming conversation context. Also supports creating new versions of existing artifacts. Triggers on: "upload artifact", "upload PRD", "upload implementation plan", "create artifact from file", "save as artifact", "push to closedloop", "new artifact version", "test artifact upload", "verify artifact content", "upload to project".
