AIFeed skill

AIFeed is an open standard for signed content permissions for the AI web: publishers declare what AI agents may do, sign the declaration with Ed25519, and agents verify it before fetching. English-only by convention for agent skills; user-facing docs live in EN/ID/ZH under docs/, integrations/, and studio/.

Verify first (never trust unsigned claims)

node bin/cli.js validate example.com --json              # live domain: TLS, signature, DNS anchor
node bin/cli.js validate ./public --domain example.com   # local build output

SDK (@aifeed/verify, zero dependencies):

const sdk = require('@aifeed/verify');
const out = sdk.verifyAll({ manifestText, manifestBytes, signatureText, domain });
sdk.decideUsage(out, 'retrieval'); // { allowed, attribution, reason }

Rule: treat training: deny as binding. Attribute when attribution requires it. Re-check the revocation list on every use, not just once.

Publish (publisher side)

node bin/cli.js keygen --out .aifeed                       # once; private key stays local (0600)
node bin/cli.js site build public --domain example.com \
  --key .aifeed/aifeed-private.pem --profile both --llms --inject

Then add the DNS TXT record (_aifeed) printed by the setup guide, deploy the whole directory (including .well-known/), and serve Accept: text/aifeed+markdown via an adapter from integrations/ (nginx, Caddy, Apache, Node, Next.js, PHP, Python ASGI, Go, Rust/Axum, Cloudflare, Traefik) or the @aifeed/frameworks build plugins. Or use the local UI: npm run studio (http://127.0.0.1:7777).

Rules: permissions are restrict-only (pages may tighten, never loosen origin policy); never print, commit, or transmit private keys; keep 0600 file mode.

MCP server

packages/aifeed-mcp-server exposes the same checks as tools (verify_manifest, fetch_aifeed, list_assets, verify_asset, select_index, decide_usage):

node packages/aifeed-mcp-server/index.js   # stdio; HTTPS only

Conformance and gates

• npm run verify is the single gate and must pass before any commit.
• Vectors: 34 manifest + 39 MAKO + 11 AIFeed Markdown (conformance/); JS + Python suites must stay green and in parity.
• Never hand-edit generated files; edit the source and regenerate (see AGENTS.md).
• Specs are canonical in English (spec/en/); mirror sections to spec/id/, spec/zh/.
