chore: address Copilot review round 1

- skill-manifest: the closing `---` fence must occupy a whole line. `---oops`
  was accepted as a terminator, silently truncating the frontmatter and passing
  validation — the exact failure the guard exists to catch. Regression cases
  added (prefix, trailing whitespace, EOF, CRLF).
- skill-eval: reject a nonzero `claude -p` exit instead of resolving it as an
  empty observation. An auth error or rate limit was scoring as "no skill
  invoked", which passes every negative case and reads as a trigger miss on
  every positive one.
- skill-eval: extract `collectSkillInvocations` / `sampleHit` behind a `main()`
  guard and cover them in `skill-eval.test.mjs` — the stream parsing and the
  process-outcome handling are unreachable from an eval run's happy path.
- docs/test-servers: annotate the era on every catalogue row. Six legacy rows
  carried no annotation under a "unless noted, Modern" default, so the doc sent
  readers to the wrong era for the feature they were trying to see.
- docs/quality-gate: `validate` runs four guards, not three; add the
  `verify:skills` row and the two new `test:scripts` suites; fix the `#publishing`
  fragment left dangling by the split.
- issue-create / pr-flow: delegate the card steps to `/board-ops` rather than
  restating its option IDs, which are explicitly unstable.
- issue-triage: the audit counted presence, not cardinality — an issue carrying
  both `v1` and `v2` passed a check that claims "exactly one". Same for the five
  type labels. Also scope the two milestone checks to board #28.
- AGENTS.md: codify the v1 milestone exception. Every milestone is a v2 release
  bucket, so a v1 issue has none to take and the Incoming-milestone invariant
  cannot apply to board #11.
- clients/launcher/README: its pointer promised an explanation of why the cli/tui
  manifests ship, which the extracted guide does not make.

| `npm run validate` | Runs the three durable guards first — `verify:format-coverage` (every tracked source file is format-gated), `verify:typecheck-coverage` (every one lands in a tsconfig project), `verify:dep-lockstep` (no dependency reaching one `tsc` program from two installs skews across them) — then `test:scripts` (the guards' own parser unit tests), then `validate:core` (the shared `core/` `format:check` + `lint` gate), then per client: `format:check` + `lint` + **`typecheck`** (cli/tui/launcher; web typechecks via `tsc -b` inside its `build`) + `build` + fast unit tests. The quick inner-loop check. |
| `npm run validate` | Runs the four durable guards first — `verify:format-coverage` (every tracked source file is format-gated), `verify:skills` (every `.claude/skills` manifest parses, declares its invocation mode, and carries eval cases), `verify:typecheck-coverage` (every tracked TS file lands in a tsconfig project), `verify:dep-lockstep` (no dependency reaching one `tsc` program from two installs skews across them) — then `test:scripts` (the guards' own parser unit tests), then `validate:core` (the shared `core/` `format:check` + `lint` gate), then per client: `format:check` + `lint` + **`typecheck`** (cli/tui/launcher; web typechecks via `tsc -b` inside its `build`) + `build` + fast unit tests. The quick inner-loop check. |
| `npm run coverage` | The **per-file ≥90% gate** (lines/statements/functions/branches) under v8 instrumentation, per client. CI-enforced. For web this also runs the integration project and covers the shared `core/` runtime (including `core/json` and `core/client`). |
| `npm run smoke` | End-to-end smokes through the built launcher (`--help` dispatch + prod cli/tui/web — the TUI one runs under a **pseudoterminal** and asserts the Ink app is still running two seconds after its first frame, not merely that it painted one, [#2147](https://github.com/modelcontextprotocol/inspector/issues/2147)), plus three headless-browser smokes: a boot smoke that runs the prod web bundle and asserts a clean first render (no uncaught error — sync exception or unhandled rejection, how a Node built-in reaching the browser bundle manifests), and an **MCP Apps** smoke (`smoke:web:app`) that drives connect → open app → `data-app-status="ready"` against a composable App server, covering the sandbox proxy and UI-protocol bridge, and an **app-rendered elicitation** smoke (`smoke:web:elicit`) that drives one end to end — call the tool, answer inside the sandboxed app, see the app's `ElicitResult` reach the server — and then the same tool against a server that never advertised the capability, which must fall back to the native elicitation form. Those three take their engine from `SMOKE_BROWSER` — see [Supported browsers](#supported-browsers). A fourth, **`smoke:web:tabs`**, drives the core tabs against one server on one browser launch — Tools runs a tool and asserts its `structuredContent` section, Resources reads a resource with templates listed, Prompts fetches one ([#2148](https://github.com/modelcontextprotocol/inspector/issues/2148)) — asserting the `data-*` contract in [the web README](../clients/web/README.md#core-tab-automation-contract) rather than visible copy. It is **Chromium-only**: those tabs are ordinary React and Mantine, so unlike the sandbox they are not engine-sensitive. |
| `npm run verify:build-gate` | Runs a real `vite build` with a Node built-in forced into the browser graph and asserts the build **fails** via the #1769 gate (which turns Vite's browser-externalization warning into a hard error). Guards against the warning phrasing drifting in a Vite bump and silently disabling the gate. Part of `npm run local:gate` and of GitHub CI. |
| `npm run verify:bundle-externals` | Guards the must-not-bundle invariant (#2067): for each tsup-bundled client it reads the **built** `build/` output and fails if any package that must stay external was inlined anyway. Candidates are the union of the client's own `external` array **and the root manifest's `dependencies`** — the latter because #2067 was a *missing* `external` entry, which a self-referential check would have passed. Detection is via esbuild's `// <path>` module banners, so it covers both shapes — a separate `<pkg>-HASH.js` chunk (what a dynamically `import()`ed CommonJS package produces) and a statically-imported package folded straight into `index.js`, which emits no chunk at all. A build with no banners fails as such rather than passing clean, so enabling `minify` cannot silently retire the check. `undici` was declared only in the root and `clients/cli` manifests, and tsup auto-externalizes only what the _nearest_ manifest declares, so the web and TUI bundles inlined 1.05MB of it — and CommonJS inlined into an ESM bundle throws `Dynamic require of "assert" is not supported` on first use, from a specifier no user-side install can satisfy. Reads the output rather than the config because those two disagreed for four releases. Part of `npm run local:gate` and of GitHub CI. |
| `npm run verify:format-coverage` | Parses the `format:check` globs out of every `package.json` (only those reachable from `validate`), enumerates all tracked source files, and **fails** listing any not covered by a glob — the durable guard for the "every first-party source file is format-gated" invariant (#1792). Runs first in `validate`. |
| `npm run test:scripts` | Table-driven unit tests (`node --test`) for the guard's own pure parsers (`scripts/lib/npm-scripts.mjs`, `scripts/lib/tsc-program.mjs` + the exported helpers of `verify-typecheck-coverage.mjs` and `verify-dep-lockstep.mjs`), one case per rule they encode, plus two suites over shared `scripts/lib` helpers that no smoke can check itself: `resolve-node-bin.test.mjs` — the cross-platform bin resolver (#1939), pinned against the real `bin`/`exports` shapes of the packages the scripts actually spawn — and `announced-child.test.mjs` — the spawn/readiness ownership helper (#2000), which drives real `node -e` children to prove a child that never announces is still published to the caller before the timeout throws, and so is reachable by teardown rather than orphaned. Four more do the same: `mcp-app-flow.test.mjs` covers the shared MCP Apps flow (#2003) — the deep link's two CSRF gates and `appArgs` encoding, plus `driveAppFlow`'s failure branches against a stand-in page, all of which are dead code from the happy-path smokes' point of view and would otherwise surface only as opaque timeouts; `render-smoke.test.mjs` and `pty.test.mjs` cover the TUI boot harness ([#2147](https://github.com/modelcontextprotocol/inspector/issues/2147)) — the former driving real `node -e` stubs to prove that a child which paints the marker and *then* dies is a **failure**, which the old harness reported as OK and which no fixed TUI can reproduce; the latter pinning the three mutually-incompatible `script(1)` invocations, where a wrong guess stops the pseudoterminal from being allocated at all; and `ensure-test-servers.test.mjs` pins the [#2111](https://github.com/modelcontextprotocol/inspector/issues/2111) invariant — that `test-servers/build` is rebuilt **even when it already exists** — which no smoke can assert about itself, since one driving a stale fixture reports a product failure rather than a staleness one. `workflow-gate.test.mjs` is a different shape again ([#2146](https://github.com/modelcontextprotocol/inspector/issues/2146)): besides the table of parser cases it runs the parser over the repo's real `.github/workflows/**`, so a workflow that invokes the local-only gate or a non-Chromium engine pass fails here rather than in a CI run nobody expected to be red. Runs in `validate` — and `verify:typecheck-coverage` guards *this* gate in turn (reachable from `validate`, non-empty test set, every test file matched by the `test:scripts` glob), since `node --test` silently skips a file its glob misses and still exits 0. |
| `npm run verify:skills` | Guards `.claude/skills` ([#2163](https://github.com/modelcontextprotocol/inspector/issues/2163)). A skill's body loads only when it is invoked, so one that stops being reachable loses behavior **silently** — and the way that happens is frontmatter Claude Code cannot parse, which loads the body with an *empty* description: `/skill-name` still works, so a manual spot check passes, while nothing is left for the model to match against. This parses each `SKILL.md` the same way, requires an explicit invocation mode on every skill and committed eval cases (positives **and** negatives) on every model-invoked one, and fails when the skill listing exceeds its recorded character budget. Also runs `claude plugin validate` when that CLI is on PATH — but does not depend on it, since it is absent in CI. Runs in `validate`. |
| `npm run test:scripts` | Table-driven unit tests (`node --test`) for the guard's own pure parsers (`scripts/lib/npm-scripts.mjs`, `scripts/lib/tsc-program.mjs` + the exported helpers of `verify-typecheck-coverage.mjs` and `verify-dep-lockstep.mjs`), one case per rule they encode, plus two suites over shared `scripts/lib` helpers that no smoke can check itself: `resolve-node-bin.test.mjs` — the cross-platform bin resolver (#1939), pinned against the real `bin`/`exports` shapes of the packages the scripts actually spawn — and `announced-child.test.mjs` — the spawn/readiness ownership helper (#2000), which drives real `node -e` children to prove a child that never announces is still published to the caller before the timeout throws, and so is reachable by teardown rather than orphaned. Four more do the same: `mcp-app-flow.test.mjs` covers the shared MCP Apps flow (#2003) — the deep link's two CSRF gates and `appArgs` encoding, plus `driveAppFlow`'s failure branches against a stand-in page, all of which are dead code from the happy-path smokes' point of view and would otherwise surface only as opaque timeouts; `render-smoke.test.mjs` and `pty.test.mjs` cover the TUI boot harness ([#2147](https://github.com/modelcontextprotocol/inspector/issues/2147)) — the former driving real `node -e` stubs to prove that a child which paints the marker and *then* dies is a **failure**, which the old harness reported as OK and which no fixed TUI can reproduce; the latter pinning the three mutually-incompatible `script(1)` invocations, where a wrong guess stops the pseudoterminal from being allocated at all; and `ensure-test-servers.test.mjs` pins the [#2111](https://github.com/modelcontextprotocol/inspector/issues/2111) invariant — that `test-servers/build` is rebuilt **even when it already exists** — which no smoke can assert about itself, since one driving a stale fixture reports a product failure rather than a staleness one. `workflow-gate.test.mjs` is a different shape again ([#2146](https://github.com/modelcontextprotocol/inspector/issues/2146)): besides the table of parser cases it runs the parser over the repo's real `.github/workflows/**`, so a workflow that invokes the local-only gate or a non-Chromium engine pass fails here rather than in a CI run nobody expected to be red. Two more arrive with the skills (#2163): `skill-manifest.test.mjs` pins the frontmatter contract one case per rule — most importantly that a fence which is not a whole line is not a terminator, and that malformed YAML is an error rather than an empty description — and `skill-eval.test.mjs` covers the trigger eval's stream parsing and its process-outcome handling, which an eval run's happy path never reaches and which would otherwise report a plausible hit rate for a CLI that failed to run. Runs in `validate` — and `verify:typecheck-coverage` guards *this* gate in turn (reachable from `validate`, non-empty test set, every test file matched by the `test:scripts` glob), since `node --test` silently skips a file its glob misses and still exits 0. |
| `npm run verify:typecheck-coverage` | The typecheck-coverage analog of the above (#1791): for each Node client (auto-discovered from disk — enrolled via its `typecheck` script's projects, or for a `tsc -b` client like `clients/web` via its `tsconfig.json` `references`) it runs those projects with `tsc --listFilesOnly`, unions them, and **fails** listing any tracked `.ts`/`.tsx`/`.mts`/`.cts` under the client that lands in no project (so a new top-level config/helper can't silently go untypechecked). It also requires, deny-by-default, the first-party TS no client owns (`test-servers/src`, the root `vitest.shared.mts`, all of `core/`, and any new top-level location) to land in some client project's tsc pass — so a `core` `*.tsx` web's projects don't reach is caught too. Also asserts the gate is wired (each client's typecheck pass — its `typecheck` script, or web's `tsc -b` — is reachable from its `validate`, and the root chain runs each client's `validate`). Runs in `validate`. |
| `npm run verify:dep-lockstep` | Guards the "one version per install-crossing dependency" invariant (#1896). v2 is not a workspace, so a client's test project compiles the shared first-party TypeScript — `core/`, `test-servers/src`, and the root-owned `vitest.shared.mts`, all of which resolve their dependencies from the **root** install — alongside the client's own sources, putting the same package in one `tsc` program twice. At the same version that's harmless; skewed, TypeScript must relate two structurally-distinct copies of every type, which for a recursive-generic surface is exponential (zod `4.3.6` vs `4.4.3` exhausted the 4GB tsc heap in `clients/web`). Derives its candidate set from **what actually enters each program** (#1965) — every client tsconfig project listed with `tsc --listFilesOnly` via the shared `scripts/lib/tsc-program.mjs`, each resolved `node_modules` file mapped to its owning install, keeping the packages that reach one program from two installs (a package whose declarations arrive only through another package's `.d.ts`, as `@modelcontextprotocol/sdk`'s do, is invisible to a scan of first-party imports). Prices each copy from the lockfile entry for the exact install path the program resolved, compares only the installs that met in one program, and **fails deny-by-default** on any disagreement not in the annotated `TOLERATED_SKEW` allowlist — empty today — with an allowlisted package tolerated only *within a major version*. Runs in `validate`.
| `npm run local:gate` | **Mandatory pre-push command.** `validate` → `coverage` → `verify:build-gate` → `verify:bundle-externals` → `smoke` → `smoke:web:firefox` → `local:storybook`. A strict superset of GitHub CI — see [Two tiers](#two-tiers-github-ci-and-the-local-gate). Named `local:` rather than `ci` on purpose (#2146); there is no `npm run ci` alias. |
| `npm run pack:verify` | Publish smoke — see [Publishing](#publishing). |
| `npm run pack:verify` | Publish smoke — see [Publishing](./publishing.md). |
Per-client scripts exist too (`validate:web`, `coverage:cli`, `smoke:tui`, …), plus root `validate:core` / `format:core` for the shared `core/` package, `format:scripts` for the root `scripts/` tooling, and `format:shared` / `lint:shared` for the root "shared" surface (`test-servers/src/**`, `vitest.shared.mts`, the root `eslint.config.js`). Run `npm run format` before committing — the root `format` fixes `core/`, the root `scripts/`, the shared surface, and every client; `validate` runs the non-fixing `format:check` and fails CI on any unformatted file.
