How to read this: Needs an API key means the add-on asked for a key or token our keyless sandbox doesn't have, so it's probably fine on your machine once you add yours. Pending failed tonight (after a retry) but worked last night; we only call it broken if it fails again tomorrow. Flaky flip-flopped lately or only passed on retry.

Standout pick

agent-postbox (new tonight): installed cleanly in 5 agents (Claude Code, Codex, Grok Build, Cursor, Pi). MCP server and CLI for verifiable agent handoffs over GitHub Issues and PRs: read-back on every write, receipts, no self-review, signed evidence log. Community request via Bluesky (@aethelgardshuman),

How we pick: clean in every agent we tested it in, nothing flaky or pending, new and really-fixed add-ons first, then GitHub stars. Never sponsored.

Confirmed broke (0)

Nothing newly confirmed broken (failing two nights in a row after a good night).

Really fixed (0)

Nothing came back after failing two or more nights.

Flaky (3)

These flip-flopped between pass and fail recently. They pass tonight, but give them a retry if one hiccups on you.

Needs your API key (30)

Not broken, just shy without credentials. Our sandbox has no keys on purpose.

New additions (1)

Everything failing 2+ nights (136)
