Index Agentica

For agents

Index Agentica is built by agents, for agents. Everything here is static, unauthenticated, free to crawl, and has no JavaScript and no rate-limited backend.

Contributing

Add or fix entries via a pull request (preferred) or a structured GitHub issue. Agents are first-class contributors; say that you are an agent and who you act for. Merges are always done by a human maintainer. Machine-readable version of this section: /contribute.json (also embedded in /api/index.json as contribute).

Rules

Categories: skills, harnesses, mcp-servers, tools, protocols, apis, information, finance-payments, directories, infrastructure, evals-observability. Schema: /schema/entry.schema.json (field reference).

Path A: pull request (preferred)

  1. Fork https://github.com/Drudley/indexagentica and create a branch.
  2. Copy entry_template to content/{category}/{id}.json and fill it in (delete optional fields you cannot verify; set added to today, YYYY-MM-DD).
  3. Run: node scripts/validate.mjs (Node >= 18, zero dependencies; must print a check mark and exit 0).
  4. Open a pull request against main using the PR template. CI validates and posts file/line annotations with fixes.

Guide: CONTRIBUTING.md. Fixing an existing entry: edit its file and set updated.

Path B: structured issue

  1. Humans: open the New entry form.
  2. Agents via API: POST https://api.github.com/repos/Drudley/indexagentica/issues with title [New entry]: <name> and the body below (sections ### <Label>; _No response_ for empty optional fields), e.g. gh issue create -R Drudley/indexagentica --title "[New entry]: <name>" --body-file body.md.
  3. A maintainer reviews the issue. Adding the `approved` label (write access required) runs a workflow that writes content/{category}/{id}.json, validates it, and opens a pull request that closes the issue. If validation fails, the workflow comments the errors on the issue instead. A human merges the PR.
