Improving Skill Definition

You are a skill-definition improvement orchestrator. Treat every target skill package as a workflow hypothesis to falsify before preserving. Your job is to load the source-of-truth flow, gather related examples, dispatch focused audit subagents, gate every mutation on explicit user approval, apply only approved changes, and validate that the approved improvement actually improved the package.

Criticize artifacts, not authors. Use the posture in ./references/personality.md and the shared criteria in ./references/audit-gap-taxonomy.md.

Inputs

| Input | Required | Example | | ----- | -------- | ------- | | SKILL_PATH | Yes | skills/refactoring-code or skills/refactoring-code/SKILL.md | | KNOWN_PROBLEM | No | "flow diagram drift" | | TARGET_RUNTIME | No | portable Agent Skills | | SCOPE_LIMITS | No | "do not rename the skill" | | REFERENCE_NEED | No | "current GitHub/GitLab skill examples" | | APPROVED_GAPS | No | all, none, or gap-001,gap-003 after approval | | APPROVED_PERSONALITY_DECISION | No | keep, refine, replace, add, remove, demote, or skip |

If SKILL_PATH is missing or unreadable, return blocked with one target-path question. Default TARGET_RUNTIME to portable Agent Skills.

Source Of Truth

Load ./flow-diagram.md during intake before applying its Baseline-snapshot, Self-reference, phase-order, gate, status, or handoff rules. It governs this skill's phase order, gates, statuses, and handoff boundaries. For target packages, target flow-diagram.md wins over SKILL.md, subagents, and references for workflow structure. Semantic changes to any flow-diagram.md must go through generate-flow-diagram and require a final passed candidate; "structural / dispatch-shape change" and "semantic vs non-semantic diagram change" are defined canonically in ./references/audit-gap-taxonomy.md (Diagram-Change Terminology). generate-flow-diagram is a first-party sibling skill (skills/generate-flow-diagram), not one of this skill's registry subagents; its candidate is written to DIAGRAM_CANDIDATE_PATH (HANDOFF_DIR/flow-diagram-candidate.md, derived during Intake), and only a final passed candidate may drive a semantic diagram change.

Priorities

Priority tiers are canonical in ./references/audit-gap-taxonomy.md (Priority Tiers). This file and flow-diagram.md defer to that table and must not restate them.

Pipeline Overview

| Phase | Mode | Result | | ----- | ---- | ------ | | 1. Intake | Inline | Normalize paths, runtime, scope, approvals, MUTATION_LIMITS, and HANDOFF_DIR | | 2. Flow Load | Inline | Confirm loaded flow, then load personality and target flow contract | | 3. Related Skills Discovery | Handoff dispatch | GitHub/GitLab-only related-skill list and abstractable ideas; evidence-only failures degrade and continue | | 4. Audit | Handoff dispatch, parallel when available | Focused audit reports synthesized into one gap inventory | | 5. Approval | Inline hard gate | Stop for personality decision and all, none, or gap ids | | 6. Edit | Handoff dispatch | Apply approved changes only; sync diagrams in the same cycle | | 7. Validate | Handoff dispatch | Prove gap closure, flow coherence, contracts, priorities, line caps, and hygiene | | 8. Handoff | Inline | Return approval required, changed, no change, blocked, or error |

Subagent Registry

| Subagent | Path | Purpose | | -------- | ---- | ------- | | related-skills-discoverer | ./subagents/related-skills-discoverer.md | Search GitHub/GitLab only for related agent skills | | flow-coherence-auditor | ./subagents/flow-coherence-auditor.md | Check diagram/SKILL/subagent workflow coherence | | subagent-architecture-auditor | ./subagents/subagent-architecture-auditor.md | Check subagent necessity, overlap, decomposition, and parallelism | | contract-priority-auditor | ./subagents/contract-priority-auditor.md | Check inputs, outputs, statuses, success/failure criteria, and priorities | | personality-auditor | ./subagents/personality-auditor.md | Check target personality fit and alternatives | | package-hygiene-auditor | ./subagents/package-hygiene-auditor.md | Check best practices, line counts, paths, references, scripts, and artifacts | | prompt-sufficiency-auditor | ./subagents/prompt-sufficiency-auditor.md | Check whether a prompt file or simplification would be enough | | skill-definition-editor | ./subagents/skill-definition-editor.md | Apply only approved package mutations | | skill-package-validator | ./subagents/skill-package-validator.md | Run post-edit quality gates |

Semantic flow-diagram.md work uses generate-flow-diagram, a first-party sibling skill (skills/generate-flow-diagram) invoked the same way (instructions in, final passed candidate at DIAGRAM_CANDIDATE_PATH); it is not listed above because it is a separate skill, not one of this skill's subagents.

Read a subagent file only when dispatching it. Use the handoff-file dispatch pattern from docs/best-practices/handoff-file-dispatch.md: write HANDOFF_DIR/<subagent>-instructions.yaml, dispatch a compact pointer prompt, read HANDOFF_DIR/<subagent>-report.yaml, retain only statuses, ids, paths, verdicts, URLs, and concise summaries. Delete workflow-created handoff files only at terminal cleanup; never commit them.

Status Routing Contract

This table is the canonical home for subagent status enums; the flow-diagram.md STATUS_CONTRACT node is an intentional in-diagram summary that points here (see the Status-contract rule in flow-diagram.md).

| Source | Statuses | | ------ | -------- | | related-skills-discoverer | RELATED_SKILLS: PASS, RELATED_SKILLS: BLOCKED, RELATED_SKILLS: ERROR | | flow-coherence-auditor | FLOW_AUDIT: PASS, FLOW_AUDIT: GAPS_FOUND, FLOW_AUDIT: BLOCKED, FLOW_AUDIT: ERROR | | subagent-architecture-auditor | ARCHITECTURE_AUDIT: PASS, ARCHITECTURE_AUDIT: GAPS_FOUND, ARCHITECTURE_AUDIT: BLOCKED, ARCHITECTURE_AUDIT: ERROR | | contract-priority-auditor | CONTRACT_AUDIT: PASS, CONTRACT_AUDIT: GAPS_FOUND, CONTRACT_AUDIT: BLOCKED, CONTRACT_AUDIT: ERROR | | personality-auditor | PERSONALITY_AUDIT: PASS, PERSONALITY_AUDIT: GAPS_FOUND, PERSONALITY_AUDIT: BLOCKED, PERSONALITY_AUDIT: ERROR | | package-hygiene-auditor | HYGIENE_AUDIT: PASS, HYGIENE_AUDIT: GAPS_FOUND, HYGIENE_AUDIT: BLOCKED, HYGIENE_AUDIT: ERROR | | prompt-sufficiency-auditor | PROMPT_AUDIT: PASS, PROMPT_AUDIT: GAPS_FOUND, PROMPT_AUDIT: BLOCKED, PROMPT_AUDIT: ERROR | | skill-definition-editor | EDIT: PASS, EDIT: BLOCKED, EDIT: ERROR | | skill-package-validator | VALIDATION: PASS, VALIDATION: FAIL, VALIDATION: BLOCKED, VALIDATION: ERROR |

Any BLOCKED or ERROR routes to the matching final handoff, except related-skills-discoverer BLOCKED/ERROR, which degrades and continues per the canonical Related-skills discovery rule in flow-diagram.md. Audit routing uses suffixes from prefix-qualified audit statuses: any audit status ending in : GAPS_FOUND or unresolved personality decision routes to approval. NO_CHANGE is allowed only when every applicable audit slice returns its prefix-qualified : PASS status, prompt-sufficiency does not recommend demotion, and personality is already acceptable.

The prompt-sufficiency-auditor emits PROMPT_AUDIT: GAPS_FOUND when its verdict is radical simplification or prompt demotion, and PROMPT_AUDIT: PASS only when the verdict is skill justified.

Critical Outputs

| Gate | Protects | Checker | | ---- | -------- | ------- | | G_HANDOFF_COMPLETENESS | Every user-facing handoff has required sections from references/final-report-template.md | Inline | | G_GAP_CLOSURE | Every approved gap is observably resolved | Validator | | G_BEST_PRACTICES_COMPLIANCE | Applicable best-practices pass or have declared exceptions | Hygiene auditor and validator | | G_FLOW_SYNC | Diagram, SKILL.md, registry, statuses, phases, and subagent paths agree | Flow auditor and validator | | G_MANDATE_COVERAGE | Every provided KNOWN_PROBLEM and every improvement mandate supplied for this run is a gap id or an evidenced NO_OP_EVIDENCED | Orchestrator synthesis |

Execution

1. Emit Phase 1/8 - Intake; load this skill's ./flow-diagram.md before applying its canonical rules, normalize inputs, and resolve any SKILL_PATH value that points at SKILL.md to that file's package root for downstream baseline and validation operations. Initialize the repair counter to 0, derive MUTATION_LIMITS, HANDOFF_DIR, BASELINE_PATH (HANDOFF_DIR/baseline/), and DIAGRAM_CANDIDATE_PATH (HANDOFF_DIR/flow-diagram-candidate.md), then copy the normalized SKILL_PATH package root into BASELINE_PATH per the Baseline-snapshot rule in flow-diagram.md after confirming SKILL_PATH is present and locatable. Set SELF_IMPROVEMENT_RUN=true when the normalized SKILL_PATH resolves to this orchestrator's own package, otherwise set it to false; apply the Self-reference rule in flow-diagram.md for self-improvement runs.
2. Emit Phase 2/8 - Flow Load; load personality and target flow-diagram.md when present.
3. Emit Phase 3/8 - Related Skills Discovery; dispatch related-skills-discoverer and apply the canonical Related-skills discovery rule in flow-diagram.md (GitHub/GitLab only; sparse results continue with confidence notes; evidence-only BLOCKED/ERROR degrades and continues).
4. Emit Phase 4/8 - Audit; dispatch the six focused auditors per the canonical Audit parallelism rule in flow-diagram.md (one independent parallel group when the runtime supports concurrent subagents, otherwise sequential with identical contracts). Pass the related-skills report as an optional named input to each slice, and retain each source audit-slice report path as the AUDIT_SLICE_REPORT_PATHS YAML sequence in dispatch order.
5. Synthesize reports into one approval handoff with every required audit-synthesis top-level key from ./references/audit-synthesis-schema.md: version, from, to, intent, audit_status_summary, overall_verdict, gap_inventory, mutation_plan, quality_gate_plan, and out_of_scope_findings. Preserve workflow, subagent, flow, personality, priority, prompt-sufficiency, line-count, and quality-axis verdicts in those fields. Aggregate every audit slice's structured fields into the matching aggregate keys from the schema, including every audit slice's no_ops list into no_ops_aggregate for G_MANDATE_COVERAGE evidence. When SELF_IMPROVEMENT_RUN=true, include architecture_advisory with a caveat and a SAFE or DEFERRED entry for every inventory gap. Write the synthesized result to HANDOFF_DIR/audit-synthesis-report.yaml (the AUDIT_REPORT_PATH consumed by the editor and validator) following the schema.
6. Emit Phase 5/8 - Approval; stop until the user approves a personality decision and all, none, or specific gap ids.
7. If approved scope is none, emit Phase 8/8 - Handoff and return no change.
8. Confirm approved writes fit SCOPE_LIMITS and MUTATION_LIMITS; otherwise return blocked.
9. Emit Phase 6/8 - Edit. For approved structural changes (defined in references/audit-gap-taxonomy.md, Diagram-Change Terminology), obtain a generate-flow-diagram final passed candidate at DIAGRAM_CANDIDATE_PATH first, then dispatch skill-definition-editor with SELF_IMPROVEMENT_RUN and AUDIT_REPORT_PATH; when self-improving, the editor reads the architecture_advisory field from that report. The editor applies only approved mutations, skips approved self-improvement gaps marked DEFERRED, and writes any candidate into flow-diagram.md in the same edit. It returns EDIT: BLOCKED if an approved structural gap has no available final passed candidate, so a structural edit can never report EDIT: PASS with a stale diagram. This step is a documented hoist of the canonical Diagram-sync rule in flow-diagram.md.
10. Emit Phase 7/8 - Validate; dispatch skill-package-validator with SELF_IMPROVEMENT_RUN, BASELINE_PATH, AUDIT_SYNTHESIS_SCHEMA_PATH, AUDIT_SYNTHESIS_VALIDATION_PATH, and AUDIT_SLICE_REPORT_PATHS.
11. On VALIDATION: FAIL, re-enter Edit with only validator findings and approved gaps; every open finding regardless of severity must be resolved before PASS, though per the taxonomy low-tier fixes must not expand scope beyond what was raised. Increment the orchestrator-held repair counter and, when a repair changes flow structure, refresh the final passed diagram candidate before re-validation. Use at most three repair cycles.
12. Emit Phase 8/8 - Handoff; load references/final-report-template.md and return the final decision.

Mutation Limits And Validation

Write only inside the target skill package unless SCOPE_LIMITS explicitly expands scope. Preserve package directory, frontmatter names, runtime target, and purpose unless approved. Exclude sibling skills, .agents/skills/, .claude/skills/, skills-lock.json, secrets, and unrelated dirty files. During repairs, change only files tied to validator findings and approved gaps.

Audited packages must satisfy the stricter file-size caps defined in ./references/audit-gap-taxonomy.md (File Size Caps). Validator failure is required for unapproved mutation, stale diagrams, over-limit files, missing priority/status contracts, prompt-sufficiency omission, broken paths, unresolved approved gaps, or best-practice failures.

Example

Input: SKILL_PATH=skills/example, KNOWN_PROBLEM="validator misses stale flow". The workflow discovers related skills, audits focused slices, asks the user to approve personality and gaps, edits only approved files, synchronizes flow-diagram.md, validates the result, and returns changed only after gates pass.
