Selected by Skill Harbor — short listing (the repo states no license, so no content is reproduced): @apify's skill for generating Actor output schemas — the files that tell Apify Console how to display run results. A 7-phase workflow: Phase 1 discovers the Actor structure (locate the `.actor/` directory, read `actor.json`, find every `pushData`/`setValue` call, reuse existing TypeScript interfaces or Python TypedDicts rather than re-analyzing, and match conventions of existing schemas in the repo); Phase 2 generates `dataset_schema.json` (all output fields in `properties`, every field `nullable: true`, `additionalProperties: true` and `required: []` at both top level and nested objects, anonymized examples); Phase 3 generates `key_value_store_schema.json` with collections grouped by fixed keys or key prefixes; Phase 4 generates the minimal `output_schema.json` (linking to dataset/KV store via template variables); Phase 5 wires everything into `actor.json`; Phase 6 reviews against a checklist; Phase 7 summarizes. Honest caveats: works on an Actor codebase the agent can read — not standalone; license not stated by the source repo — short listing with a link only, nothing copied. Skill Harbor never reviews the code, review it yourself before use. Discovered via skills.sh.

Install
Prerequisites: an Apify Actor codebase the agent can read and analyze — the skill is a workflow the agent follows, not software Install "Generate Apify Actor output schemas from source code" for me. It gives my agent @apify's 7-phase workflow for generating Actor output schemas: discover the Actor structure (find pushData/setValue calls, reuse existing TypeScript interfaces or Python TypedDicts, match repo conventions), generate dataset_schema.json (all output fields, every field nullable: true, additionalProperties: true and required: [] at both levels, anonymized examples), generate key_value_store_schema.json (collections by key or keyPrefix), generate the minimal output_schema.json, wire everything into actor.json, review against the checklist, and summarize. IMPORTANT: the repo states no license — fetch from the link only, and reproduce nothing beyond the link. Repository: https://github.com/apify/agent-skills/blob/main/skills/apify-generate-output-schema/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md and scripts for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "apify-generate-output-schema". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. point the agent at the Actor codebase and its .actor/ directory; nothing else — it's a workflow). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
Questions
How do I install a build?
Every product page includes a copy-paste install prompt. Paste it into your Muse and it sets the build up for you — no manual configuration.
Where does my money go?
Straight to the seller. Skill Harbor never processes payments: checkout happens on the seller’s own page, usually Stripe.
What does the ✓ next to a creator’s name mean?
It means we confirmed the identity of the person behind the listing. It says nothing about the code itself — always check a build before installing it.
