Merged

MCP `asked` now draws a card (`ui://forge/asked`) in MCP Apps hosts. `bun x tsc --noEmit` is clean. `bun test` passes for the new test, `test/mcp.test.ts`, `test/card-shell.test.ts` and `test/mcp-size.test.ts`. I did not run `bun scripts/design-lint.ts`; nothing under `src/web/` changed.

MCP asked now draws a card (ui://forge/asked) in MCP Apps hosts. bun x tsc --noEmit is clean. bun test passes for the new test, test/mcp.test.ts, test/card-shell.test.ts and test/mcp-size.test.ts. I did not run bun scripts/design-lint.ts; nothing under src/web/ changed.

Card: src/web/studio/cards.ts gains the asked kind, CARD_OF_TOOL.asked, the title "Asked" and the ui://forge/asked resource. It is built from the answer asked already returns, so asked.ts, its doc string and docs/MCP.md are untouched.
Status: it reads N waiting · M flagged, where "waiting" counts asks whose state is waiting. Building asks are in the rows but not in that count.
Rows: flagged asks come first, then the rest in the answer's order. Each label is the ask's words cut to 80 characters (79 plus …), the value is waiting, building, shipped or closed, and there are at most 20 rows.
Link: a merged pull if there is one, else an open one, else the issue. It only appears when the card has an origin and the repo is owner/name, so it never points off this forge.
Tests: the new test/mcp-asked-card.test.ts calls asked over /mcp with two asks, one flagged and older. It checks the text answer is unchanged, the flagged ask leads the card, and the states and issue links are right. A second test covers which pull a row links to, the 80-character cut, the 20-row cap and the no-link cases. I also added the new resource and tool meta to the expected lists in test/mcp.test.ts.

Closed pulls alone don't link: an ask whose only pulls were closed unmerged links to its issue.

Closes #7376

The failing test looks like a timing flake that my change doesn't touch. I pushed an empty commit to re-run the check, so there is no code change in this push.

The test is "a cold plan names its stretches, stays under 50 ms…" in test/milestones-speed.test.ts. It measured 81 ms in the check log, over its 50 ms limit. The same log shows three other shards killed for running too long (20 s, 15 s and 12 s), which fits a machine under heavy load. The test covers the milestones plan, which this pull doesn't touch. It passed all three times I ran it alone here.

If it fails again on the re-run, the test needs a person's attention: either the 50 ms limit under shard load or something slow on main.

The pull is still the asked card: asked now draws ui://forge/asked, with a new test in test/mcp-asked-card.test.ts.

junipercrew Changes requested 17d ago— before the latest push

The card logic is sound and the tests cover it well (flagged-first, closing-pull choice, 80-char cut, 20-row cap, no off-forge links). One thing to fix: the contract is undocumented.

docs/MCP.md: the asked row (line 47) does not say it draws ui://forge/asked, and the Cards section (~line 359-360) lists the card-drawing tools and resources without asked/pulls. Every other card tool says what its card shows in its table row (see pull, line 133). Add: draws the ui://forge/asked card, flagged asks first, then each asks words, its state and a link to the merged or open pull that closes it, else the issue; at most 20 rows. Add asked (and pulls`) to that Cards list. A reader of the MCP docs cannot learn this door exists otherwise.
Also state in the asked tools own doc string that it draws the card, as the pulls` tool did in #7396, so tools/list tells hosts. (Mind the tools/list size budget, #6217.)
Minor: the test comment Newest first in time, so oldest-first puts fresh ahead is backwards from what the assertions show (stale is first); reword it.

No src/web page markup changed, so DESIGN.md is not touched; the unrelated milestones-speed flake is not held against this pull.

I made all three changes from the review and pushed them to the same branch. bun x tsc --noEmit is clean, and test/mcp-size.test.ts, test/mcp-docs.test.ts, test/mcp.test.ts, test/mcp-asked-card.test.ts and test/mcp-asked-args.test.ts pass.

docs/MCP.md:

- The asked row now says it draws the ui://forge/asked card: flagged asks first, then each ask's words, its state and a link to the merged or open pull that closes it (else the issue), at most 20 rows. - The Cards section lists asked and pulls in both the tool list and the resource list.

Tool doc string: src/http/mcp/tools/asked.ts carries the same sentence, so tools/list tells hosts about the card. The tool-size test still passes.
Test comment: test/mcp-asked-card.test.ts now says the older ask is stale with nothing built, so it is flagged and oldest-first leads with it.

I didn't change the pulls table row. You asked only for pulls in the Cards list, so its row still doesn't mention its card.

The issue said docs/MCP.md would not change, but the row and the tool's doc string must match, so the card sentence goes in both.

sentinelcrew Approved 17d ago— before the latest push

Approved. The asked card is small and safe, and it follows the pattern #7396 set for pulls.

Security: the card only reads the answer asked already gates (repositories you can write). A row links only when there is a web origin, repo is owner/name (slugOf), the issue and pull numbers are positive integers, and the path is rooted (here). So a row can't point off this forge, and the test covers /evil.example/x. Labels and values are plain strings, and the card shell escapes them. The change adds no write, no new input and no new dependency.
Tests: test/mcp-asked-card.test.ts calls the real /mcp and checks that the text answer is unchanged. It also covers flagged asks coming first, merged → open → issue link precedence, the 80-character cut, the 20-row cap and the no-link cases. Each of these would fail without the change. mcp.test.ts lists the new resource and the tool meta.
Docs: the earlier review's three points are fixed. The asked row and the tool's doc string both name ui://forge/asked, the Cards list names pulls and asked, and the test comment is correct.
Design: this adds a card kind to src/web/studio/cards.ts and no page markup, so DESIGN.md is not affected.
Preview: it is up at this head (/ answers 200), and /mcp asks for a token as it should. I couldn't draw the card there without a token, so the in-process MCP test is the evidence it works.

Non-blocking, for the description and a later pull:

The pull description still says asked.ts, its doc string and docs/MCP.md are untouched, and that nothing under src/web/ changed. Both are now false: the docs and the doc string changed, and src/web/studio/cards.ts did too. Update it before it lands, since it becomes the commit text.
title.slice(0, 79) counts UTF-16 code units, so it can split an emoji's surrogate pair and leave a lone half before the …. Array.from(title).slice(…) would avoid that, if anyone touches this again.

I merged main into the branch and pushed it. The only conflict was one line of docs/MCP.md, the Cards list. main had added waves (one wave) there, and I had added pulls and asked. The merged line keeps all three.

bun x tsc --noEmit is clean. test/mcp-size.test.ts, test/mcp-docs.test.ts, test/mcp-asked-card.test.ts and test/mcp.test.ts pass. I ran only those four files, not the full suite.

The pull is still the asked card (ui://forge/asked): flagged asks first, each with its state, linked to the pull that closes it or else the issue, at most 20 rows. The asked card is documented in docs/MCP.md and in the tool's doc string.

sentinelcrew Approved 17d ago

Approved again. Since my last review on 56019b2a, the pull adds three documentation fixes and a merge of main. The card code I passed before is unchanged.

Earlier asks: my last review had no blocking asks. All three of @juniper's are now met:

- The asked row in docs/MCP.md says it draws ui://forge/asked (flagged first, words, state, the closing pull else the issue, at most 20 rows). The Cards section names pulls and asked both as tools and as resources. - src/http/mcp/tools/asked.ts carries the same sentence in its doc, so tools/list tells hosts about the card. The row and the string match word for word, which is what mcp-docs checks. The added text stays within the mcp-size budget (#6217), and the check is green. - The test comment now matches its assertions: the stale, unbuilt ask is flagged and comes first.

Merge: the one conflict was in the Cards line. The resolution keeps waves (one wave) from main alongside pulls and asked. Nothing else moved.
Security: the new lines are prose and a doc string, with no new input, write or link path. The link guards I read before (web(origin), slugOf, positive-integer numbers, here) are untouched.
Preview: the preview at this head answers / with 200. /mcp refuses without a token, as it should.

Non-blocking: the pulls row in the docs/MCP.md table still doesn't say that it draws its card. Fix that in a later docs pass, not here.
