Use when authoring a project-local or installable skill, refining its trigger description, adding deterministic scripts or Python sidecars, or testing whether another Agent can follow the workflow.</h2>\n<h1>Create Wisp skills</h1>\n<p>Author project-local skills under <code>.wisp/skills/&lt;name&gt;/</code>. Wisp also discovers\nbundled skills, user-installed skills, and paths configured by\n<code>WISP_SKILLS_PATH</code>, but only normal project paths are directly writable through\nAgent file tools.</p>\n<h2>Structure</h2>\n<pre><code>&lt;skill-name&gt;/\n├── SKILL.md               # frontmatter trigger + procedure body\n├── kernel.py              # optional pure helper definitions\n├── scripts/               # optional standalone deterministic programs\n├── references/            # optional detailed domain material\n└── assets/                # optional output templates or static inputs\n</code></pre>\n<p>Keep <code>SKILL.md</code> concise. Put triggering information in frontmatter\n<code>description</code>; put essential procedure in the body; move detailed variants to\none-level-deep references. Add only resources the workflow actually uses.</p>\n<h2>Workflow</h2>\n<ol>\n<li>Define concrete user requests that should trigger the skill and the expected\noutputs.</li>\n<li>Search existing skills before creating a duplicate.</li>\n<li>Choose a lowercase hyphenated name and create\n<code>.wisp/skills/&lt;name&gt;/SKILL.md</code> with <code>write</code>.</li>\n<li>Add reusable scripts before writing long inline code examples. Execute every\nnew script on representative local data.</li>\n<li>Add <code>kernel.py</code> only for small reusable Python helpers. Loading a skill does\nnot inject Wisp tools into Python. The rendered skill supplies a one-time\n<code>exec(compile(open(...)))</code> instruction that defines the sidecar names in the\npersistent <code>python</code> kernel.</li>\n<li>Validate structure with this skill's\n<code>scripts/quick_validate.py &lt;skill-directory&gt;</code>.</li>\n<li>Refresh or reopen the project if the new skill does not yet appear, then find\nit with <code>search_skills</code> and load it with <code>use_skill</code>.</li>\n<li>Exercise the skill on realistic tasks. When explicit Wisp delegation is\navailable, use a fresh bounded task with only the skill path and user-style\nrequest; do not leak the expected answer into the evaluation prompt.</li>\n</ol>\n<p>For a user-wide installation, ask the user to install the validated folder via\n<strong>Settings → Skills</strong>. There is no Agent-side publish, overwrite, or delete API.</p>\n<h2>Frontmatter</h2>\n<p>At minimum include:</p>\n<pre><code>---\nname: my-skill\ndescription: Perform X. Use when the user asks for Y, Z, or related output.\n---\n</code></pre>\n<p>The folder name and <code>name</code> should match. The description is the primary trigger;\nstate both what the skill does and when it should be selected.</p>\n<h2>Python sidecar rules</h2>\n<p>Keep top-level code definition-only:</p>\n<ul>\n<li>allow imports, function definitions, and literal constant assignments;</li>\n<li>defer optional third-party imports into function bodies;</li>\n<li>do not run work, access the network, or modify files at load time;</li>\n<li>do not depend on injected Agent, Run, credential, artifact, or model objects;</li>\n<li>pass paths and configuration explicitly;</li>\n<li>use <code>python</code> to call helpers after the one-time loader instruction.</li>\n</ul>\n<p>Use <code>scripts/</code> instead when a helper is a standalone CLI, exceeds roughly one\nhundred lines, needs argument parsing, or should run through <code>run_in_context</code>.</p>\n<h2>Bundled scripts</h2>\n<ul>\n<li><code>scripts/quick_validate.py &lt;skill-dir&gt;</code> — checks frontmatter shape, kebab-case\nnaming, folder/name match, and length limits; prints every problem at once.</li>\n<li><code>scripts/package_skill.py &lt;skill-dir&gt; [out-dir]</code> — validates, then zips the\nfolder into <code>&lt;name&gt;.skill</code> for user-wide installation, skipping build junk\nand a root-level <code>evals/</code> folder.</li>\n</ul>\n<p>To evaluate a skill, run it on realistic tasks yourself (step 8 above) and keep\nevaluation artifacts out of the skill folder unless they are intentional\nreusable resources.</p>\n<h2>Wisp boundaries</h2>\n<ul>\n<li><code>search_skills</code> and <code>use_skill</code> do not edit the catalog.</li>\n<li>Project file tools cannot manage user-wide installed skills outside granted\nworkspace paths.</li>\n<li><code>run_in_context</code> executes deterministic work; it does not publish skills or\ncall models.</li>\n<li>Specialist creation is separate. Load <code>customize</code> and use\n<code>save_specialist</code> only when that explicit tool is advertised.</li>\n</ul>\n","files":[{"path":"scripts/package_skill.py","sizeBytes":2148,"isText":true},{"path":"scripts/quick_validate.py","sizeBytes":4388,"isText":true},{"path":"SKILL.md","sizeBytes":5059,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
