Skill creator

Create Wisp skills

Author project-local skills under .wisp/skills/<name>/. Wisp also discovers bundled skills, user-installed skills, and paths configured by WISP_SKILLS_PATH, but only normal project paths are directly writable through Agent file tools.

Structure

<skill-name>/
├── SKILL.md
├── kernel.py              # optional pure helper definitions
├── scripts/               # optional standalone deterministic programs
├── references/            # optional detailed domain material
└── assets/                # optional output templates or static inputs

Keep SKILL.md concise. Put triggering information in frontmatter description; put essential procedure in the body; move detailed variants to one-level-deep references. Add only resources the workflow actually uses.

Workflow

1. Define concrete user requests that should trigger the skill and the expected outputs.
2. Search existing skills before creating a duplicate.
3. Choose a lowercase hyphenated name and create .wisp/skills/<name>/SKILL.md with write.
4. Add reusable scripts before writing long inline code examples. Execute every new script on representative local data.
5. Add kernel.py only for small reusable Python helpers. Loading a skill does not inject Wisp tools into Python. The rendered skill supplies a one-time exec(compile(open(...))) instruction that defines the sidecar names in the persistent python kernel.
6. Validate structure with this skill's scripts/quick_validate.py <skill-directory>.
7. Refresh or reopen the project if the new skill does not yet appear, then find it with search_skills and load it with use_skill.
8. Exercise the skill on realistic tasks. When explicit Wisp delegation is available, use a fresh bounded task with only the skill path and user-style request; do not leak the expected answer into the evaluation prompt.

For a user-wide installation, ask the user to install the validated folder via Settings → Skills. There is no Agent-side publish, overwrite, or delete API.

Frontmatter

At minimum include:

---
name: my-skill
description: Perform X. Use when the user asks for Y, Z, or related output.
---

The folder name and name should match. The description is the primary trigger; state both what the skill does and when it should be selected.

Python sidecar rules

Keep top-level code definition-only:

• allow imports, function definitions, and literal constant assignments;
• defer optional third-party imports into function bodies;
• do not run work, access the network, or modify files at load time;
• do not depend on injected Agent, Run, credential, artifact, or model objects;
• pass paths and configuration explicitly;
• use python to call helpers after the one-time loader instruction.

Use scripts/ instead when a helper is a standalone CLI, exceeds roughly one hundred lines, needs argument parsing, or should run through run_in_context.

Evaluation resources

Use the bundled scripts only when their extra rigor is useful:

• scripts/run_eval.py for test prompts;
• scripts/aggregate_benchmark.py for repeated result aggregation;
• scripts/generate_report.py and eval-viewer/ for human review;
• scripts/improve_description.py for trigger-description experiments;
• scripts/package_skill.py to package a validated skill folder.

Inspect each script's CLI help before running it. Keep evaluation artifacts out of the skill folder unless they are intentional reusable resources.

Wisp boundaries

• search_skills and use_skill do not edit the catalog.
• Project file tools cannot manage user-wide installed skills outside granted workspace paths.
• run_in_context executes deterministic work; it does not publish skills or call models.
• Specialist creation is separate. Load customize and use save_specialist only when that explicit tool is advertised.
