* chore: land the #2247 round-9 review findings on v2/main
Copilot filed a ninth review round on #2247 after it had merged, so none of
it reached v2/main. All five findings are addressed here.
1. The testing -> test-servers hand-off delivered the wrong half of the
procedure. test-servers documented only the two-process manual path
(server-composable.js --config <name>.json plus a second Inspector
process), but an integration test builds the server in-process from the
@modelcontextprotocol/inspector-test-server API and owns its lifecycle.
Adds a "Two ways to use a fixture — pick the right one first" section
with the in-process recipe, the four mechanics that bite (one barrel,
start/stop in afterEach, read started.url, era is a constructor option),
and a pointer to the reference test; renames "Run one" to "Run one by
hand (two processes)" so the manual path names itself. testing now says
in the connecting bullet that an automated test does NOT spawn.
2. testing's heading asked "does the test need a real server?", which its
own hand-rolled-server exception contradicts. It now asks whether the
test uses a test-servers/ fixture.
3. "imports" was too broad a dependency test — test-server-scope.test.ts
imports the package to unit-test scope middleware as a pure function and
never starts a server. The condition is now "starts, spawns, or
configures", with that test named as the counterexample.
4. docs/skill-authoring.md attributed the 33% -> 100% rise to imperative
wording and placement independently. The #2247 edit changed both at
once, so only the combination is established; the split into two levers
is now labelled the plausible mechanism, not a measured result.
5. The CHAIN_THRESHOLD comment generalised "a well-shaped pointer clears
0.8" from one two-case run of that same multi-variable edit. It now
reads as an existence proof about the ceiling, not a property of
pointers in general.
Also records the headline lesson where it can be found again: a green
hand-off number proves skill B loaded, never that B answered the question —
in AGENTS.md's chain-case rules and in the skill-authoring checklist.
Docs, skill bodies and one comment only; no runtime code changes.

* fix: address Copilot review round 1 on #2264
The new section claimed two shapes and there are three — the automated
stdio path was missing, and it is the repo's established pattern
(getTestMcpServerCommand() into a stdio transport, used by five web
integration files and the whole CLI suite). Telling callers an automated
test "does not spawn" told them not to use it.
- test-servers: "Two ways" -> "Three ways", with a table and a subsection
for the spawned-stdio shape — the transport owns the child (disconnect,
not stop()), no config can be selected because that entry point runs the
stdio default, and it is still the build. Names a reference test for it.
- test-servers: the build is no longer scoped to the manual path. All three
shapes resolve test-servers/build/ — two through the barrel alias, one by
running the emitted .js — so the staleness hazard is called out as
applying to every shape, and `Build first` no longer opens by claiming
the only reason is subprocess spawning.
- testing: the "does not spawn" instruction is replaced by the two
automated shapes and when to pick each. What they share, and what the
hand-off actually needed to say, is that neither picks a showcase config.

* fix: address Copilot review round 2 on #2264
Round 1 fixed the missing stdio shape but kept the wrong axis. Cutting
the taxonomy by "automated vs by hand" excluded the config-driven smokes
— smoke-web-elicitation.mjs spawns server-composable.js --config
directly, and lib/mcp-app-flow.mjs does it for smoke:web:app,
smoke:web:tabs and pack:verify. Those are automated AND need every bit
of the config and protocol-era guidance a person at two terminals does,
so the skill was routing their authors away from it.
- test-servers: the cut is now how the SERVER IS STOOD UP, stated as
such. Third shape is "spawned composable HTTP", whose consumers are
the smokes, pack:verify, and a person by hand — the config/era
guidance belongs to the shape, whoever starts it. Table gains a
Consumers column and loses the Who column that caused this.
- test-servers: the stale "an automated test builds the server
in-process instead" line under `Run one by hand` is gone (suppressed
comment); that heading is now the same shape driven by a person.
- testing: routes by what is driving — integration/CLI test to
in-process HTTP, stdio-is-the-point to spawned stdio, and a smoke to
the composable-config path with the era guidance it actually needs.

* fix: address Copilot review round 3 on #2264
Round 2 replaced one wrong axis with a narrower one: it routed "a smoke"
wholesale to the config-driven composable path, and smoke:cli does not
use it. smoke-cli.mjs starts an in-process createTestServerHttp for the
header round-trip (so it can read back what the CLI sent) and writes the
built stdio entry into a --catalog for the connect checks; smoke:tui uses
only the latter. Neither picks a config.
- test-servers: consumers filled in per row — in-process HTTP gains CLI
tests and smoke:cli, spawned stdio gains smoke:cli and smoke:tui, and
the composable row is narrowed to the WEB smokes. A warning states the
point directly: "a smoke" is not a shape, pick by the row.
- test-servers: the stdio shape now covers naming the built entry in a
catalog without connecting, which is what those two smokes do.
- testing: same narrowing, plus the reason spelled out so the word
"smoke" stops being a routing key.
- testing: the dependency criterion said "starts, spawns, or configures",
which excluded the build-only smoke:tui case documented directly above
it — the skill both required and rejected the hand-off for it
(suppressed comment). It now reads "starts, spawns, configures, or
hands a built entry to the subject under test".

Ink writes styling as escape sequences inside the styled run, so an
accelerator underline splits the word it decorates: `<Text underline>I</Text>nfo`
reaches the frame buffer with escapes between `I` and `nfo`, and a plain
`toContain("Info")` fails against a component that is rendering correctly.
Chalk only emits color when it detects a TTY, so CI stays green and the six
failures land only on a developer whose shell exports FORCE_COLOR.
Add `__tests__/helpers/renderTui.tsx` — ink-testing-library's `render` with
`lastFrame()` and `frames` ANSI-stripped — and point all 16 renderer test
files at it. `frames` is a getter reading through to the live array, since
Ink appends to it as the component re-renders; the raw bytes stay reachable
as `stdout.lastFrame()`.
Pinning FORCE_COLOR=0 would turn the six green while hiding the class: any
future assertion on styled text has the same problem, and the suite would
stop covering the styled path at all.

Copilot, all three accepted.
1. Connecting still is not the condition. A few integration tests
deliberately hand-roll a JSON-RPC server because the composable
fixture *cannot* produce what they assert on —
`inspectorClient-malformed-list.test.ts` says so in its own header:
"the SDK's own server cannot emit these shapes: they are exactly what
its types forbid". Same for `listSalvage-era.test.ts`. Real
transport, real client, zero `test-servers/` dependency.
Round 4 already stated the right condition at the top — "does this
test depend on a fixture from `test-servers/`" — and then three
downstream sites went on saying "connects". Those are now scoped to
fixture use, and the hand-rolled exception is stated where the
trigger is defined rather than left to be discovered, with both files
named. Connecting is kept as a hint, since it usually does imply a
fixture, with the instruction to check whether one can express the
case first.
2. "description-strength measurement" was the wrong surface, and this
PR is what made it wrong: a chained prompt is deliberately written so
the target's *description* cannot fire on it, so the number measures
the pointer in the first skill's body and nothing else. Left as-is it
would send the next person tuning a red hand-off at the description.
3. "an 0.8 bar" -> "a 0.8 bar".

Copilot, accepted. Round 4 split the trigger into two branches and
fixed the closing section, but left the paragraph that ends the opening
section speaking for both — asserting a real transport and a protocol
era for the build-only case that lines 28-31 had just established has
neither.
Scoped explicitly: "In the connecting case …" keeps the transport and
protocol-era guidance, "In the build-only case …" says that guidance
does not apply and names what is actually wanted from `test-servers`
there — how to build the fixture, and why a stale build keeps serving
old code.
Re-measured: 100% / 100% hand-off, 63/63 first-move at 100%, full suite
at RUNS=5.

Copilot, both accepted.
1. "Anything that puts a built fixture on disk" matches every web test,
not the case it was written for: `clients/web`'s `pretest` runs
`test-servers:build` ahead of every unit run, so the fixture is on
disk for the pure parser and storage tests the very next paragraph
excludes. The trigger contradicted its own exclusion list.
Re-keyed to depending on the artefact — the test imports, spawns, or
points a config at it — with the pretest fact stated as its own ⚠️ so
the distinction is legible rather than implied.
2. The closing section still said the fixture-consuming case needs "a
real server over a real transport" and a protocol era, which is
exactly false for the build-only consumer round 3 added. `smoke:tui`
drives no transport, so config choice and protocol era do not apply
to it — only the build and staleness half does.
The condition is now stated once, with two named sub-cases that say
which part of `test-servers` each needs: connecting takes the whole
procedure, naming-the-artefact takes the build half. The closing
section mirrors that split instead of collapsing them.
Re-measured: 100% / 100% hand-off, 63/63 first-move at 100%, full suite
at RUNS=5. Unchanged across all four rounds.

Copilot, both nits accepted — the first is a correctness hole, not a nit.
1. `smoke:tui` never asserts a round trip, so round 2 filed it under
"boot-only, needs nothing". It calls
`ensureTestServers({ requires: ["stdio"] })` and hands the built
fixture to the TUI as its catalog's stdio command
(scripts/smoke-tui.mjs:105-124) — which means the staleness hazard,
the single most expensive thing in `test-servers`, lands on it in
full. Connecting was the wrong sole condition.
The trigger is now "does this test **connect to, or build and
consume**, an MCP fixture?", with `smoke:tui` named at all three
decision points and the fixture-consumption case given its own
paragraph in the closing section.
2. The "29 of 74" figure was brittle and I could not reproduce it
against a different pattern: 29 by my grep, 32 by a direct
`@modelcontextprotocol/inspector-test-server` import, 39 by a wider
union. A number whose value is a function of the grep does not belong
in a skill body that nobody re-runs. Dropped; the concrete
counter-examples stay, which is what actually carries the point —
`storage/store-id.test.ts` validates a string and `mcp/import/*`
parses config files, both sitting beside live-connection tests.
Re-measured after broadening the condition: 100% / 100% hand-off,
63/63 first-move at 100%, full suite at RUNS=5. Unchanged across all
three rounds.

Copilot, both findings accepted — and the first is the same defect one
level down from round 1.
1. Round 1 replaced "a smoke" with a transport condition but left "an
integration test" unqualified, and left the tier note treating web
integration as wholly fixture-dependent. It is not: **29 of the 74
files in `src/test/integration/` reference a server at all.**
`storage/store-id.test.ts` validates a string; `mcp/import/*` parses
config files. They sit there for the node env and the 30s timeout —
placement is the project manifest, which is exactly why it cannot
also be the fixture trigger.
All four sites now say "an integration test **that connects**" and
name the counter-examples, including the folder-is-not-the-trigger
point at the `integration` bullet itself, and the tier ⚠️ now states
that the boundary cuts *across* the tiers rather than along them.
2. Replacing the worked example orphaned the warning after it: "the two
runs above straddle a 67-point swing … with no change to the pointer"
had nothing left to refer to, since the 33%/33% and 100%/33% pair it
names was gone and the runs on show differed by 20 points across a
pointer rewrite. The weak-pointer pair is restored as its own
paragraph, the warning names both figures explicitly, and the 20-point
intermediate is now framed as RUNS=5 residual noise — contrasted with
the 67, rather than standing in for it.
Re-measured, since "that connects" narrows the phrasing the two chain
prompts have to match: 100% / 100% hand-off, 63/63 first-move at 100%,
full suite at RUNS=5. Unchanged from round 1.

Copilot, both findings accepted.
1. The trigger was over-broad. "a smoke" and "everything from web
integration rightwards" routed work to `test-servers` that needs no
fixture at all: `smoke:launcher` only checks `--help`, `smoke:web`
asserts the SPA is served, `smoke:web:browser` stops at first paint,
and Storybook play functions render from fixture props. The condition
is now "does this exercise MCP behaviour over a transport?", stated
as such, with both sides named — the smokes that connect
(`smoke:cli`, `smoke:web:app`, `smoke:web:elicit`, `smoke:web:tabs`)
and `pack:verify` on one side, the boot-only ones and Storybook on
the other. Depth in the tier list is explicitly not the boundary.
2. The threshold rationale contradicted the new result. It said an 0.8
bar would mark a hand-off red "regardless of how strongly the first
skill points at the second" — which the 100% measurement refutes.
Both copies (docs and `skill-eval.mjs`) now say what 0.5 actually
buys: a floor on useful reliability for a noisier second-hop load, so
the column still separates an adequate pointer from a broken one. The
value is unchanged.
Re-measured after the narrowing, since a tighter trigger could have
weakened the pointer: 100% / 100% on the hand-off and 63/63 first-move
at 100%, full suite at RUNS=5. Recorded figure updated from the
intermediate 100% / 80%.

The hand-off measured 33% / 33% at RUNS=3 (#2204's two committed chain
cases). `testing` opened with a one-sentence ⚠️ *classifying* which work
belongs to `test-servers` — a fact, which the model skims — and said it
nowhere else except a bare cross-reference in the last section.
Rewrite it as an action with a trigger ("load the `test-servers` skill
now — that is step one"), enumerate the situations that qualify, and
repeat the pointer at the two later points where the run actually
decides it is writing an integration test: the `integration` project
bullet under "Where the test file goes", and the tier list. The top of a
body is read before the model knows it needs the second skill, so a
pointer that lives only there has already been scrolled past by the time
it matters.
Measured at RUNS=5 on the full suite: the two hand-off cases go to
100% / 80% (100% / 100% on a focused `-- test-servers` run), and all
63 first-move cases stay at 100% — no displacement, as expected, since
neither description changed.
Also update the two places that recorded the old number as the standing
state: the worked example in `docs/skill-authoring.md`, and the
`CHAIN_THRESHOLD` rationale in `scripts/skill-eval.mjs`, which cites the
33% measurement as the reason the bar is 0.5 rather than 0.8. The bar is
unchanged — a reshaped pointer raises the ceiling those two cases reach,
not the floor a new hand-off case should be judged against.

Adds a multi-name filter to `npm run skills:eval` so a set of related
skills can be iterated together, and makes an unknown name a hard error
rather than an empty run — a typo would otherwise report a green 0/0
that reads exactly like a clean pass of the skill that was meant.
Re-aims two `local-dev` cases and one `test-servers` case that partially
overlapped `AGENTS.md`. Partial overlap oscillates across runs rather
than sitting at zero, so it reads as eval noise instead of a defect in
the case; `docs/skill-authoring.md` now records that failure mode and
the observed scores.
Widens the `test-servers` description to the "Use when …" shape and
points the `testing` skill at it, since anything needing a real server
to run against is a procedure `testing` does not carry. That growth
moves the skill listing from 2,921 to 3,144 of 4,000 characters, so the
figure recorded in AGENTS.md is updated to match.

`skills:eval` was at 38/46 with several skills measuring 0-33%. The low
scores were mostly bad eval cases rather than bad descriptions, for two
reasons that were nowhere written down:
- The harness runs each case with `--max-turns 1`, so the skill has to be
the model's FIRST tool call. A prompt asking "how does X work here", or
naming a concrete file, sends the model to Read/Grep first — a better
answer to the question, scored as a miss. Every 0% case was one of these.
- `AGENTS.md` is resident on every turn, so a prompt it already answers is
answered without any skill and the case can never pass.
Replace the cases that measured the wrong thing, expand every model-invoked
skill from 3 to 5 positives (negatives kept) so one flake cannot cross the
threshold, and reshape `local-dev`'s description to the action-first form.
Add `docs/skill-authoring.md` with the case shapes that fire, the ones that
cannot, and the probe-then-measure loop.
RUNS=5 npm run skills:eval: 63/63 at or above threshold, 60 at 100%,
all 18 negatives clean.

Measured before and after at the same sample size (n=4), with the six other
model-invoked skills unchanged:
which command runs the TUI suite 25% → 100%
asserting on a Mantine transition 50% → 100%
which tier spawns the built binary 25% → 100%
The lever is the description's SHAPE, not its length: leading with the actions
and then enumerating concrete situations ("Use when … ; when … ; when …") beats
a noun-phrase list of contents ending in a generic "use for any question
about …". The same edit took `pre-push-gate` from 3/5 to 5/5 earlier.
Re-ran the full eval to check the change did not simply move attention off
another skill, which is the failure the previous commit recorded: 40/46, up from
38/46, and the failing set is strictly smaller — `testing` went from three
failures to one, nothing else moved. That remaining case measured 100% in
isolation and 67% in the full run, which is sampling variance rather than a
finding.
AGENTS.md now extends the re-run rule to cover a description edit, not just a
flip, and records the shape that works.

`AGENTS.md` was one 1,223-line contract loaded in full on every turn, whether
the task was a one-line CSS fix or a release cut. This splits it: rules stay
resident, procedures move to `.claude/skills/`.
- Ten skills under `.claude/skills/`, seven `disable-model-invocation: true`
(invoked by name only, so they cost no listing context and have no trigger
question) and three model-invoked with committed eval cases.
- `AGENTS.md` 1,223 → 380 lines: rules, a skills index, and a project tree
reduced to one line per entry. The removed recipes are not duplicated.
- `README.md` 811 → 105 lines, split into `docs/{architecture,quality-gate,
test-servers,publishing,docker}.md`, and dropped from `CLAUDE.md`'s auto-load.
- `.github/copilot-instructions.md` and its mirroring rule removed — Copilot
reads `AGENTS.md`.
- `npm run verify:skills` (in `validate`, so in `local:gate` and CI) parses each
SKILL.md the way Claude Code does, requires an explicit invocation mode and
eval cases for model-invoked skills, and budgets the listing.
- `npm run skills:eval` runs the committed trigger cases headless.
