Skill2 Visualize

Visualize Skill Libraries

Present local inventory, usage, and test evidence in the terminal. When review is useful, surface delete and downgrade candidates in plain language (plus optional merge/projectize). Never modify the library.

Ownership

• Visualize presents evidence and optional read-only delete/downgrade candidates.
• Audit finds static defects.
• Test produces behavior evidence.
• Create applies approved merges, moves, or restructuring.

Method

1. Run terminal uv run --script /scripts/run -- visualize against the skill root, Codex + Claude usage roots, and test-run evidence.
2. Run read-only uv run --script /scripts/run -- suggest --json against the same roots (visualize CLI also embeds a short candidate block).
3. Present a short terminal summary only (see Output). Keep observed facts separate from inference.
4. If delete/downgrade candidates were shown, end with the Output contract question (final line).
5. Read references/lifecycle-suggestions.md only when the user asks for detailed expansion of a candidate.
6. Never modify, delete, move, or merge skill files. No HTML or report-file flow.

Interpretation

• Exact SKILL.md reads are usage evidence, not complete invocation history.
• Zero direct calls means current adapters found none; it does not prove no use.
• Broad scans, maintenance, and worker reads are not direct activation.
• Missing tests remain missing; never infer pass.
• Low frequency never authorizes deletion.
• Delete candidate ≠ delete now. It means: no usage, no tests, no owner signal — maybe removable after human check.
• Downgrade candidate ≠ bad skill. It means: mostly broad/worker noise; might be a piece of another skill, not a standalone.

Output

Default terminal response: compact all-skill frequency chart. Target ≤ inventory skill count + 14 non-empty lines. Expand only after the user asks for detail.

Required default shape:

1. One summary line (inventory totals + key usage/test counts).
2. Compact all-skill terminal bar chart — exactly one row per skill in inventory (include zero-call skills). Sort by direct desc, then indirect desc, then name. Each row: skill name, stacked bar (█ direct + ░ indirect), D/I counts. Include a short legend under the chart.
3. Suggestions block (plain words — do not say "lifecycle"):

• Delete candidates — up to 5 (delete_candidate)
• Downgrade candidates — up to 5 (downgrade)
• Optional one-liners for merge/projectize only if present
• If a bucket is empty, print (none) for that bucket

1. One evidence-limit line.
2. Final yes/no detailed-review question only when at least one delete or downgrade candidate was shown.

Do not print by default:

• the word "lifecycle" (too abstract for users)
• boxed tables (no box-drawing borders)
• full keep tables
• separate full zero-call list (zeros belong in the all-skill chart)
• repeated facts already shown above
• full evidence methodology / interpretation essay

Hard contract — when any delete or downgrade candidates are shown:

• Final line of the reply must be a direct yes/no question about those candidates.
• Required intent (match user language): ask if they want a detailed review.
• English form must include want a detailed or detailed review.
• If the user is writing in another language, mirror that language for the question only; skill body stays English.
• Do not auto-apply delete/downgrade/merge actions.
