Adds Hanging Context (https://hangingcontext.com), a free news site written by an agent for agents. Every 12 hours an agent publishes stories on AI, finance, science, health, sports, government, energy and culture. Every paragraph cites its sources, and quotes are checked word for word before publication.
Keyless and FREE. Every endpoint is a public GET with no account, key or OAuth. The provider declares an empty credentials shape and an identity inject (the opoint#suggest pattern), and the usage model is FREE, so there is no consolidate.

Tests. Fixtures were recorded 2026-10-24 from the live site, with long lists trimmed to 2 entries. The replay tests cover the happy paths, an ask with no match, and a story 404 settling at zero. Live tests need no credential, so they are gated on --allow-net (they run under test:live). deno test connectors/hangingcontext: 7 passed, 3 ignored; with --allow-net: 10 passed. deno fmt, deno lint and deno check are clean, and ids.lock.json is updated with the 4 new ids.
Note: I ran the tests on Windows. scripts/lib.ts fails there (os error 123 on the deno.json path), so I did not run catalog or ids:check locally; the CI tasks should cover them.
The change adds a keyless Hanging Context provider and four GET endpoints: /ask, /latest, /story, and /n/{topic}/index.json. It adds input schemas for query, story path, and topic path parameters. Recorded fixtures cover successful responses, no-match answers, provider errors, and not-found responses. Replay tests cover endpoint behavior, and live tests run when network permission is granted.
Priority: Normal
Merge Risk: Low · up to f54b0
The keyless live tests remain runnable, but their gates and the error fixtures do not follow the connector’s documented conventions. Align those before merging, or explicitly accept the bounded deviation.

Review comments at @connectors/hangingcontext/endpoints/ask/endpoint.test.ts:
- Around line 63-77: Add a separate provider-error replay test near the existing
no-match test, using testSealedUnit and runEndpoint with a recorded or synthetic
provider error. Assert result.isProviderError is true and result.usage
deep-equals { credits: {}, evidence: {} }; keep the successful no-match
assertions unchanged.
- Around line 44-61: Extend the `hangingcontext#ask` endpoint tests to verify
the compiled query schema rejects an empty query with `INVALID_INPUT`, and add a
passing near-twin using a nonempty query to confirm valid input remains
accepted.
- Around line 14-15: Update the shared liveSkip gate to allow an empty
required-field list to mean no credential requirements, then set this test’s
ignore condition to combine the network check with liveSkip for hangingcontext
using that empty list, so keyless live runs are not skipped.
Review comments at @connectors/hangingcontext/endpoints/ask/schema/inputs.ts:
- Line 5: Update the query field in the inputs schema to be optional, preserving
its existing validation constraints for supplied values; apply any
endpoint-specific requirement only at the binding in endpoint.ts.
Review comments at @connectors/hangingcontext/endpoints/latest/endpoint.test.ts:
- Around line 18-25: Add a provider-error replay alongside the successful case
in the endpoint test, using an HTTP-error fixture and asserting that the result
has isProviderError set to true and usage equal to empty credits and evidence
objects.
- Around line 6-7: Update the shared testing helper’s liveSkip so an explicit
empty field list supports keyless endpoints, then use liveSkip for
hangingcontext in the endpoint test and combine its result with noNet in the
ignore condition.
Review comments at @connectors/hangingcontext/endpoints/story/endpoint.test.ts:
- Around line 7-8: Add a schema-gate test alongside the existing
hangingcontext#story test that submits a near-valid slug with a trailing
underscore and verifies an INVALID_INPUT rejection; pair it with the valid
fixture slug as a passing near-twin to show the gate accepts valid input.
- Around line 32-33: Add a live test for hangingcontext#story alongside the
existing recorded test, using testSealedUnit and runEndpoint in live mode; gate
it on network permission and liveSkip with an empty credential-field list, and
assert the provider succeeds and cited_manifest_ids is an array.
Review comments at @connectors/hangingcontext/endpoints/topic/endpoint.test.ts:
- Around line 18-25: Add a provider-error replay to the endpoint test alongside
the existing happy replay, and assert that the result has isProviderError set to
true and empty usage. Reuse the test’s existing fixture and replay setup where
applicable.
- Around line 12-17: Extend the runEndpoint tests to cover the topic schema
boundary: assert that a near-valid invalid slug is rejected with INVALID_INPUT
and that its valid near-twin succeeds against the compiled endpoint.
- Around line 6-7: Update liveSkip so an explicitly empty credential-field list
requires no credentials, while an omitted list retains the apiKey default; then
gate the topic live test with liveSkip("hangingcontext", []), preserving the
network-permission check and adding the required import.
Review comments at @connectors/hangingcontext/endpoints/topic/schema/inputs.ts:
- Around line 19-21: Update the topic validator in the inputs schema to accept
any vendor-documented slug matching the lowercase alphanumeric-and-hyphen
pattern, rather than restricting values to the fixed TOPICS enum; retain the
topic description and validate only this field.

ask:query is optional in schema/inputs.ts (vendor mirror) and required at the binding with .required({ query: true }), since a bare call only returns a help page.
topic: uses the vendor's documented slug pattern ^[a-z0-9-]+$ instead of a fixed enum. The description still names today's topics.
Provider errors: synthetic 503 replays for ask and latest, and a recorded 404 for an unknown topic, all asserting isProviderError and empty usage. story already had a recorded 404.
Schema gates:INVALID_INPUT rejections plus passing near-twins for ask, topic and story.
story: added a live test.
On liveSkip: I left it alone. Hanging Context has no credential, so liveSkip("hangingcontext") would always skip, and liveSkip("hangingcontext", []) also always skips today, because envCredentialsPresent requires wanted.length > 0. Changing that would touch engine/, which a connector PR shouldn't. The live tests instead gate on network permission, so they run under test:live (--allow-net) and are ignored under test. If you'd rather make liveSkip(slug, []) mean "no credentials needed", I'm happy to send that as a separate PR.
deno test --allow-net connectors/hangingcontext: 17 passed.

Checked this against the replay code before changing anything (shared/testing/fixtures.ts, replayFetch). A shared provider-level chain cannot serve these endpoints: replay matches method and URL exactly after binding {{request.url}}, and that binding is the endpoint's compiled URL template.
503 (ask, latest):latest works with {{request.url}}, but ask fails: call 0 expected GET https://hangingcontext.com/ask, engine issued GET https://hangingcontext.com/ask?query=anything. The query string is part of the match.
404 (story, topic): both fail with the template unexpanded: expected GET https://hangingcontext.com/stories/{date}/{slug}/index.json, engine issued GET https://hangingcontext.com/stories/2026-01-01/no-such-story/index.json (and …/n/{topic}/index.json for topic).
Only latest has neither a query string nor path parameters, so a provider-level fixture would have one user and remove no duplication. Keeping the four per-endpoint fixtures with their literal URLs as they are. I ran both variants locally to confirm; the PR head is unchanged and the connector's tests pass on it (13 passed, 0 failed, 4 live tests skipped).
