An admin sends a webhook a test `ping` delivery through the API and MCP, and sees it among the deliveries #8006

Webhook ping is already implemented on this branch and already pushed. Nothing moved on the issue since my last run, so I changed nothing this run.

What it does

• POST /api/v1/repos/:owner/:name/hooks/:id/ping queues one signed ping delivery to that hook only, whatever kinds it subscribes to. The body is { kind, repo, hook, at }. It answers 202 with the delivery's id.
• MCP hooks has a ping action that takes id and answers the same.
• The ping goes through the normal delivery queue and deliverDue, so a private address is refused and shows up as a failed delivery with its reason. The request never fetches anything itself.
• The route uses the same admin gate as the deliveries route. It allows three pings per hook per minute and answers 429 past that.
• The code is in src/core/webhooks.ts, src/http/api/hooks.ts, src/http/mcp/tools/hooks.ts and the OpenAPI route postApiV1ReposOwnerNameHooksIdPing.ts. docs/MCP.md is updated.

Checks this run: bun x tsc --noEmit is clean. test/hook-ping.test.ts passes (5 tests). There is no scripts/gate.ts here, so I ran no gate. I did not run the full suite; the forge runs it on push.

To try it: as an admin, POST …/hooks/:id/ping, then read …/hooks/:id/deliveries or call MCP deliveries. The ping appears there.

I chose not to make the ping limit configurable.

Closes #7872

I merged main into the branch and pushed it. The docs/MCP.md conflict was in the hooks row, and I kept both sides. The row now has main's "(admin scope)" prefix and my ping clause.

test/hook-ping.test.ts passes (5 tests). I didn't run the rest of the suite; the forge runs it on the push.

bun x tsc --noEmit fails with one error: test/changelog.test.ts can't find happy-dom. That test file came in with main, and I didn't run bun install after the merge, so the module may just be missing from my node_modules. I didn't check that. I pushed with the error still there.

I didn't change anything. I couldn't reproduce the failure, and my pull doesn't touch the code those tests cover.

• What failed: three tests in shard 30: two in test/tui-tell.test.ts and one in test/verify-recovery.test.ts.
• What I ran: both files together, locally. All 16 tests pass.
• What my pull touches: only webhook ping (src/core/webhooks.ts, the hooks API route and MCP tool, the OpenAPI route, docs/MCP.md). Nothing in the terminal "tell" screen or the recovery links.
• Likely cause: it looks like an order or shared-state flake that only shows up when the shard runs those files with their neighbours. I only guessed that and didn't check it. The shard log in the report shows only passing tests, so I have nothing to fix against. Shard 41 was also killed after 36 s while running test/web-editor.test.ts, which points to load on the check machine.
• What to do: this needs a re-run of the check. If those same three tests fail again on a branch that doesn't touch them, the flake is already on main and needs its own issue. I'm not pushing a no-op commit just to trigger it.

A webhook ping is now stored on its own delivery and never written to the event log. The hooks settings page also has a Send ping button. I ran the gate and tsc (both clean) and 14 test files covering webhooks, the migration, route timing and the security floor (179 pass). I did not run the full suite, and bun scripts/fast.ts called 1,410 of 1,750 files too broad to name, so I picked the files myself.

1. Event log. A ping no longer writes an event row, so no feed, stream or events listing can show it, and no ping kind reaches other consumers.

- A new migration, 20261102160000-webhook-ping-own-row, rebuilds webhook_delivery with a nullable event_id and its own kind, payload and created_at, and keeps the existing rows and indexes. Its pin is committed. - deliverDue and recentDeliveries read a delivery's own columns first and fall back to the event for ordinary deliveries. A delivery with no event is sent with its stored payload { kind, repo, hook, at }. - A new test checks that the event table gains no row and that GET …/events with and without kind=ping shows nothing.

1. Web door. /:owner/:name/settings/hooks/:id/ping is a POST that goes through the existing adminForm, which does the same-origin check, the admin-scope check and the CSRF check. The Send ping button beside each hook calls pingWebhook.

- Success flashes "Ping queued", and a rate-limited ping flashes "Too many pings: try again in N s.". - Tests cover the form being on the page, a cross-site post getting 403 and queuing nothing, a good post queuing one delivery, the over-limit message, and an anonymous post being refused. - The README now describes the API, MCP and web doors.

1. Cleanup. The test header cites #8006, and the deliverOne ternary is reformatted.
2. Rate limit. It now counts webhook_delivery rows (kind = 'ping', within the window), with a partial index for it. A test shows 3 pings then a 429 with the event table holding no ping.

Not done: I did not open an issue for the CI flake in shard 30. I have no log of it, and an issue without one would be vague. Someone with the log should file it.

To try it: as a repository admin, open Settings › Webhooks and press Send ping. The ping shows as ping in that hook's delivery table. Over the API or MCP, POST …/hooks/:id/ping or the hooks tool with action: ping does the same.

Admins now get a "Send ping" button on the hooks page, and a ping is stored on its own row instead of in the repository's event log. The check had failed because the first migration rebuilt webhook_delivery, and the additive-migration guard forbids that during a roll.

What changed

• Migration: 20261102160000-webhook-ping-own-row now only adds a webhook_ping table (state, attempts, next_try_at, status, error, payload, created_at) and two indexes. webhook_delivery is untouched, so the release still in play reads the same table it always did.
• src/core/webhooks.ts: pingWebhook writes to webhook_ping, and the rate limit counts that table (3 a minute, 429 with retry-after past that).
• Delivery: deliverDue picks up due event deliveries and due pings together. The claim and the ok, failed and back-off updates go to the right table through tableOf. A ping's body is its payload unchanged, as before.
• Listing: recentDeliveries shows both kinds together, newest first, with pings labelled ping.
• Pin and test: I regenerated the .pin file for the rewritten migration. That is allowed because the migration is new on this branch and not yet on main. test/hook-ping.test.ts now resets the rate-limit window on webhook_ping.

Checks run: bun x tsc --noEmit and bun scripts/gate.ts are clean. The schema tests, hook-ping, webhooks, following-cache and tui-egress tests all pass locally. I did not run scripts/design-lint.ts, and this fix touched nothing in src/web/.

The other two failures: "an answer git failed to give is not remembered" and "private destinations in the terminal" passed when I ran their files here. I made no change aimed at them and think they were flaky under sharding. If they fail again on this push, I'll look at them separately.

Not done: I did not touch the README, which still describes the earlier approach. To try it, open /<owner>/<repo>/settings/hooks and press "Send ping". The ping shows up among the hook's deliveries and never in the repository's events.

I merged main into the branch and pushed it. The merge is clean. The only conflict was src/core/webhooks.ts. The 246 webhook-related tests pass and tsc is clean. I did not run the full suite, since the forge runs it on the push. scripts/gate.ts printed nothing I could see, so I can't say whether it ran or passed.

The conflict. Both sides had edited the same block of src/core/webhooks.ts. I kept both:

• pingWebhook and PING_LIMIT are unchanged. A ping is still a webhook_ping row, not an event.
• The new redeliver and RedeliverError from main sit beside them.

One change on top of the merge. main now makes the delivery worker skip paused hooks (w.active = 1). I added the same filter to the ping query in deliverDue. A test ping to a paused hook now waits until the hook is resumed, instead of making a request that "paused" says shouldn't happen. Say if you'd rather a ping go out regardless of pause.

The earlier summary still holds: the admin's Send ping button queues one ping delivery per hook, limited to 3 a minute, and it never touches the event log.

An admin can send a webhook a test ping from four places: the page, the API, MCP and the terminal. The ping shows up at once in that hook's deliveries.

• Core: pingWebhook in src/core/webhooks.ts queues one signed delivery with the body { kind: "ping", repo, hook, at }, to that hook only, whatever kinds it follows. It is limited to 3 a minute per hook. Pings live in their own webhook_ping table (a new migration that only adds a table), never in the event log, so no feed, stream or other hook hears of them. deliverDue sends pings the same way as other deliveries: same signing, egress refusal and retries. recentDeliveries lists both kinds of row together, newest first.
• API: POST /api/v1/repos/:owner/:name/hooks/:id/ping with an admin-scope token answers 202 { id }. Past the limit it answers 429 with retry-after. Below admin, or for a hook not in the repository, it answers 404.
• MCP: the hooks tool takes action: ping with an id.
• Web: each hook in Settings › Webhooks has a Send ping button, a same-origin POST to /:owner/:name/settings/hooks/:id/ping.
• Terminal (added in response to review): on a hook's Deliveries screen in src/tui/screens/hooks.ts, p sends a ping through pingWebhook. The screen's existing admin check covers the key. A refused ping shows a toast saying how many seconds to wait. p already means pause on the Webhooks list, but that is a different screen; I kept p here as the reviewer suggested.
• Docs: the how-to is in docs/features/webhook-ping.md and covers the page button, the API, MCP and the terminal key. I reverted the README change, so the README is untouched by this pull.

Tests:

• test/hook-ping.test.ts covers the API, MCP and page.
• test/tui-hooks-deliveries.test.ts has two new cases. One checks that p queues pings that show as ping · pending and that a 4th is refused with the wait. The other checks that someone who lost admin cannot ping.
• The anonymous page post now expects exactly 404 instead of accepting a list of statuses. That was the test being too loose, not a change in the code.

What I left out: a failed ping cannot be resent with r, because redeliver only looks at event deliveries. The doc says to send a new ping instead.

Checks: bun scripts/gate.ts and bun x tsc --noEmit pass. bun scripts/fast.ts named almost every test file (about 129 minutes), because the diff against main includes the merge, so I ran the covering files myself instead. Those were the two ping and terminal-deliveries files, test/webhook-redeliver.test.ts, test/api-hook-deliveries.test.ts, test/readme-cap.test.ts, and the other webhook, hooks and docs tests: 64 pass, 0 fail.

To try it: in the terminal, open Webhooks on a repository you administer, press enter on a hook, then p four times. Or call curl -X POST -H "authorization: Bearer <admin token>" …/api/v1/repos/<owner>/<name>/hooks/<id>/ping.
