Amaury Levé ca21fd61c1 run-tests: prompt-shaped multi-TFM keywords for plugin activation (#688)
* run-tests: use prompt-shaped multi-TFM keywords for plugin activation

The 'Run tests in a multi-TFM project targeting a specific framework' eval

scenario kept failing plugin-mode activation after #667. The skill description

had 'multi-TFM projects (--framework)' as a brief parenthetical, but the

scenario prompt uses different language: 'This test project targets both

net8.0 and net9.0. I only want to run the tests on net9.0 using dotnet test.'

Per the InvestigatingResults.md guidance for 'skill not activated' failures,

expand that clause to include keywords from the prompt — 'running tests

against a single target framework when a project targets multiple TFMs'

plus a concrete '<TargetFrameworks>net8.0;net9.0</TargetFrameworks>' example

and the '--framework <TFM>' invocation. Per-skill description is 947 chars,

well under the 1024 spec cap.

* Replace simple multi-TFM scenario with a harder MTP+SDK 9 variant that requires skill knowledge

The previous 'Run tests in a multi-TFM project targeting a specific
framework' scenario tested a trivial prompt (single --framework flag)
that the model already answers perfectly from training (baseline 4.7/5).
This matches pattern #8 (baseline already good, no headroom) in
InvestigatingResults.md, and explains why two prior attempts to fix
plugin-mode activation via description tweaks (PR #667, #688) failed:
the router rationally skips loading the skill for a trivial question.

This change replaces the scenario with a meaningfully harder one that
combines several signals the model often confuses:

  - Multi-TFM project (TargetFrameworks plural)
  - MTP runner (TestingPlatformDotnetTestSupport)
  - .NET SDK 9 (-- separator required for MTP extension args)
  - TRX report (MTP extension flag)

The correct answer requires knowing that --framework is a dotnet
test/MSBuild flag that always goes BEFORE --, while --report-trx is an
MTP extension flag that goes AFTER -- on SDK 9:

  dotnet test --framework net9.0 -- --report-trx

The ordering assertion in eval.yaml enforces this on a single line, so
swapping --framework after the separator no longer satisfies the
scenario.

Also fix a documentation bug in SKILL.md surfaced by this work: the
'Common MTP flags > Built-in flags' table previously listed --framework
and --no-build under 'On SDK 8/9, pass after --', which is wrong. Those
are dotnet test/MSBuild flags consumed by dotnet test itself; they
always go before --. The table now lists only flags genuinely consumed
by MTP, and an Important note clarifies the rule.
