Summary

This makes AgentID (provider connect and accounts) available in the Cursor, Claude Code, and Codex plugins.

• Skills: exported from Add the agentmail-agentid skill for providers and accounts agentmail-skills#17 with skills.py build --target .:
  • new skills/agentid/ (canonical agentmail-agentid, exported under the short ID agentid like send-email, so it's /agentmail:agentid and $agentid), with an MCP dependency in agents/openai.yaml
  • agentmail-mcp now covers Claude.ai / ChatGPT connector setup and the tool groups
  • check-email now uses get_message
  • the threat model gains a "Connect inbox to provider" row
• README: a new "AgentID: create accounts for your agent" section. It leads with what people ask for ("Create an account at Firecrawl for my agent", "My agent needs a web search API", "Log my agent back in to Turso"), explains what the skill carries through to (usually an API key in a secret store), and then gives the tool table and per-client invocation. It notes that unlisted providers work by ID (agentmail-to/agentmail-api#1408) and adds a safety-model bullet for provider sign-ins.
• Manifests: all four go to 0.4.0. Every manifest and the marketplace entry now use one description: "Email inboxes for agents. Create inboxes, send and receive emails, automate email workflows, and create accounts with AgentID." Keywords include agentid, the Codex longDescription explains AgentID, and one Codex defaultPrompt is now "Create an account at Firecrawl for my agent with AgentID."
• validate_repo.py: agentid is added to the skills that must declare the hosted MCP dependency.
• CHANGELOG: new 0.4.0 entry, which absorbs the Unreleased notes. I dropped the "blocked on publish" sentence, since the pins already moved to toolkit 0.5.1.

Not changed: the compatibility.json pins. check_compatibility.py reports drift that was already there before this PR: TS SDK 0.5.31, Python SDK 2.0.5, CLI 1.7.0, toolkit TS 0.9.0. Moving those pins means re-verifying the SDK signature tests, which belongs in its own PR.

Test plan

• python3 scripts/validate_repo.py: passed (4 manifests, 9 skills)
• claude plugin validate . --strict and .claude-plugin/plugin.json --strict: passed
• skills.py build --check --target . against the skills branch: clean
• After merge, reinstall in Codex, Claude Code, and Cursor, and run list_providers as a read-only check

Merge order

1. Frame provider tools around creating accounts; unlisted providers by ID; show the sign-up cap agentmail-toolkit#66, then publish agentmail-toolkit 0.9.1 to npm
2. Send server instructions that introduce AgentID providers and accounts agentmail-mcp#62 after it gains the 0.9.1 pin bump and a regenerated mcp-manifest.json, then confirm the connector deploy
3. Add the agentmail-agentid skill for providers and accounts agentmail-skills#17, re-synced with skills.py sync --backend against the regenerated manifest
4. Ship the agentmail-agentid skill and release 0.4.0 #15, re-exported from Re-export the skills with app_connect and release 0.5.1 #17 if Re-export the skills with app_connect and release 0.5.1 #17 changed
5. docs(agentid): use AgentID from Claude, ChatGPT, and Cursor agentmail-docs#279, then run Publish docs

Skills, plugins, and docs wait for the connector so they don't describe ownerSignupLimit and unlisted-by-ID behavior that the live 0.9.0 tool descriptions contradict.

The skill copies inherit the inline notes on agentmail-skills#17 (cap counting, 404 meaning); re-export after those land. Merge after the connector is on toolkit 0.9.1 (see #17).

[shalim786]

Naming nit, and cheap only before 0.4.0 ships: this becomes /agentmail:agentmail-agentid. skills.json pluginExport.legacyIds already maps agentmail-* action skills to short IDs (send-email, …). Adding "agentmail-agentid": "agentid" would give /agentmail:agentid and $agentid, consistent with the others. Renaming after release breaks installs.

[sidharth0612]

Done. skills.json in agentmail-skills#17 now maps "agentmail-agentid": "agentid" in legacyIds (863fa6f). This PR re-exports it as skills/agentid/, so it's /agentmail:agentid and $agentid (6b51153). The README, changelog, and validate_repo.py MCP-dependency set use agentid, and so does the docs guide in agentmail-docs#279. It stays agentmail-agentid on skills.sh.

[sidharth0612]

@shalim786 Re-exported after the skills#17 fixes (6b51153), with the agentid short ID applied. The merge order is in the description: this goes after the connector is on 0.9.1 and after skills#17, and gets re-exported again if #17 changes.

[shalim786]

Rename to agentid and the re-exported fixes look good (6b51153). LGTM. Merge order still applies: publish agentmail-toolkit 0.9.1 from #66, bump the connector's pin to it, regenerate mcp-manifest.json and deploy; then merge skills#17, plugins#15 and docs#279.
