Conciseness

The body is dense and operational, assumes Claude's intelligence ('Use Claude's intelligence to interpret the source material... Do NOT rely on exact section name matching') and defers bulk material to references. A few passages could be tightened — notably the long single-paragraph 'Finding sketch artifacts' conditional chain and the dense modelOverride bullet — so it sits just below the 'every token earns its place' anchor.

Actionability

Guidance is fully executable: a copy-paste script invocation ('bash ${CLAUDE_PLUGIN_ROOT}/skills/arn-code-save-plan/scripts/save_plan.sh <PROJECT_NAME> <OUTPUT_DIR> <resolved-plan-file-path>'), exact filenames for every created artifact, a section-to-source mapping table, explicit TASKS.md numbering rules, a field-by-field PROGRESS_TRACKER.json spec, and a final verification checklist. Verified that templates.md, template-versioning.md, and save_plan.sh all exist in the bundle.

Workflow Clarity

Six clearly sequenced steps with explicit validation checkpoints and feedback loops: Step 1 validates configured paths ('Validate that all paths exist on disk... warn the user'), Step 2 handles script failure ('If the script fails (non-zero exit code), report the error output... Do not proceed to Step 3 until the project structure is successfully created'), edge cases are enumerated (multiple/zero PLAN_PREVIEW files, legacy fallback), and Step 6 closes with a completion checklist. This matches the anchor-5 example pattern of validate -> fix -> retry with checklists.

Progressive Disclosure

The SKILL.md body is an operational overview that defers bulk material to real, clearly signaled, one-level-deep bundle files: templates ('using the template from ${CLAUDE_PLUGIN_ROOT}/skills/arn-code-save-plan/references/templates.md'), the version-check procedure ('Read .../references/template-versioning.md for the full template version check procedure'), and the setup script. File listing confirms all three referenced paths exist (templates.md 312 lines, template-versioning.md 57 lines, save_plan.sh 121 lines); the only external pointer (arn-code-ensure-config's preferences-schema.md) is a cross-skill plugin reference, not a nested chain.

Specificity

The description names the domain and one core action — 'convert a planning conversation into an actionable phased project structure with implementation and testing plans' — but does not enumerate the concrete artifacts it creates (INTRODUCTION.md, phase plans, TASKS.md, PROGRESS_TRACKER.json). It matches the anchor 'names domain and 1-2 concrete actions, but not comprehensive'; it is not a 4 because it never lists several specific actions.

Completeness

It explicitly answers both questions: what ('convert a planning conversation into an actionable phased project structure with implementation and testing plans') and when ('This skill should be used when the user says [12 concrete trigger phrases]... or wants to convert a planning conversation into...'). The explicit trigger-phrase list matches the anchor-5 example structure; not a 4 because 'when' is fully explicit, not just present.

Trigger Term Quality

Comprehensive coverage of natural user phrases with synonyms: "save plan", "save the plan", "export plan", "export project plan", "organize this plan", "structure this plan", "finalize the plan", "turn this into a project". These are exactly what a user would naturally say, matching the top anchor including synonyms.

Distinctiveness Conflict Risk

The core niche (planning-conversation-to-phased-project conversion) is distinct and anchored by Arness-specific triggers like "arness code save plan" and "export plan". However, generic phrases such as "set up project structure", "generate project structure", and "turn this into a project" carry overlap risk with generic scaffolding skills — minor overlap, matching anchor 4 rather than the minimal-conflict anchor 5.
