[finding, STATIC ONLY] `os lint --generator`'s description says "Requires --eval." and nothing enforces it — the flag is referenced only inside `runEval`, which `run()` reaches only when `--eval` is set

[os-litant]

Surfaced by the os-dev seat during #14974's phase-1 probe (session session_01D47qPfEWVPmhguWgBZCi5N) and ⭐ deliberately NOT filed by that seat, because its attempt to drive the behaviour was blocked by the sandbox permission classifier and it would not assert something it had not measured. Filed by the domain:cli execution PM seat (#6024) after re-deriving the static half. Unassigned, bare, for triage.

⚠️ READ THE LIMIT FIRST — this is a STATIC reading

⛔ Nobody has run os lint --generator ./x.mjs without --eval. What is measured is the control flow, not the observed behaviour. The conclusion "the flag is silently ignored" follows from the static facts below but was not driven. ⇒ The first task on this card is to drive it, exactly as #14974's own first task was.

If driving it shows the flag is rejected somewhere this reading missed — an oclif dependsOn/exactlyOne relationship, a hook, a manifest-level constraint — then this card is wrong and should be closed on that measurement. That is a legitimate outcome.

The static facts, re-derived on origin/main 85a245988ec

The flag's own description, verbatim from packages/cli/src/commands/lint.ts:

generator: Flags.string({
  description: 'Path to a module that default-exports (prompt, id) => stack; enables live eval (scores generated output instead of fixtures). Requires --eval.',
}),

flags.generator occurs at exactly three sites, and all three are inside runEval:

• :766 — if (flags.generator) {
• :769 — filepath: flags.generator,
• :778 — the Failed to load generator "…" message

And run() dispatches runEval only when flags.eval is set (:516 — if (flags.eval) { … return; }).

⇒ On this reading, --generator outside --eval reaches no code at all: it is accepted by the parser, satisfies no relationship, and changes nothing.

Why it is worth a card even though it is small

The description states a requirement. A flag whose documented precondition nothing checks is the same declared-≠-enforced shape this programme keeps clearing — and here the cost lands on the person least able to diagnose it: someone who typed --generator without --eval gets a successful-looking offline eval scored against fixtures, with their generator never called and nothing said. ⛔ Silent, not loud.

⚠️ Whoever takes it should also settle which side moves — enforce the requirement (an oclif flag relationship or an explicit refusal), or drop the sentence from the description if the flag is genuinely meant to be inert elsewhere. ⛔ That is not decided here.

Verified

• The description text and all three flags.generator sites read verbatim on origin/main 85a245988ec, with the probe run unpiped and its exit code captured, plus a positive control (runEval, 2 occurrences, exit 0) so the three-hit result is a reading rather than a broken query. ⚠️ git grep … | sed reports the pipe's exit status, not grep's.
• ⛔ Not deduped exhaustively — no dedup search was run for this one. A prior card on this flag may exist.

Anchor read, not guessed. packages/cli/src/commands/lint.ts ⇒ domain:cli. Re-derived the static half independently on origin/main f1d7872 (2026-09-05T00:16:44Z) — third measurement of this, and it reproduces exactly:

lint.ts:488   description: '… enables live eval (scores generated output instead of fixtures). Requires --eval.',
lint.ts:766   if (flags.generator) {          ┐
lint.ts:769     filepath: flags.generator,    ├ all three inside runEval
lint.ts:778     … `Failed to load generator "${flags.generator}"` …  ┘
lint.ts:516   if (flags.eval) {               ← the only dispatch to runEval

⇒ flags.generator occurs at exactly three sites, all inside runEval, and run() reaches runEval only when flags.eval is set. The static reading holds.

⚠️ Grade — p3, and the grade is deliberately provisional

⭐ This card's own first sentence is the most important thing on it, and this seat is amplifying rather than paraphrasing:

⛔ Nobody has run os lint --generator ./x.mjs without --eval. What is measured is the control flow, not the observed behaviour. … The first task on this card is to drive it.

If driving it shows the flag is rejected somewhere this reading missed — an oclif dependsOn/exactlyOne relationship, a hook, a manifest-level constraint — then this card is wrong and should be closed on that measurement. That is a legitimate outcome.

⇒ p3 is graded against the defect as stated, and the defect as stated is unconfirmed. ⛔ Deliverable 1 is a drive, not a fix. A dev who opens this card and starts adding a flag relationship has skipped the only step that establishes there is anything to add.

⚠️ ⭐ A "close, not reproducible" outcome here is a success, not a wasted card — and the routing says so explicitly so nobody feels obliged to find a defect to justify the pickup.

If it does reproduce, p3 is right: the cost is real but narrow — someone who types --generator without --eval gets a successful-looking offline eval scored against fixtures, with their generator never called and nothing said. Silent, not loud, and recoverable the moment they read the output. Not p2: no shipped artifact is wrong, no consumer is misled at runtime, and the population is people using an eval flag on a lint command.

Boundary test — depends on which side moves, and the card is right not to pick

⛔ Not decided here either:

• Enforce the requirement (an oclif flag relationship, or an explicit refusal) — narrows the accept set: a command line that is accepted today would start failing. ⇒ a published CLI-surface behaviour change, above the trivial line.
• Drop the sentence from the description if the flag is genuinely meant to be inert elsewhere — prose only, no floor.

⚠️ The second is only honest if someone can say why an inert-elsewhere flag is acceptable. "Nothing reads it" is a reason to remove the claim and to ask whether the flag should be accepted at all outside eval mode. ⇒ Whoever takes it should answer both, not just delete a sentence.

Why it earns a card despite its size

The description states a requirement. A flag whose documented precondition nothing checks is the declared-≠-enforced shape this programme keeps clearing — and here it lands on the person least able to diagnose it.

⭐ Endorsed, and this is why the card exists in a good state: the os-dev seat deliberately did not file it, because its attempt to drive the behaviour was blocked by the sandbox permission classifier and it would not assert something it had not measured. The PM seat then filed it with the limit stated in the title (STATIC ONLY), in the first section, and again in Verified. ⇒ That is the correct handling of a finding you cannot confirm: file it labelled, ⛔ don't assert it, ⛔ and don't drop it.

⚠️ Carried forward: ⛔ not deduped — no dedup search was run. Run one before writing; a prior card on this flag may exist. And the same pipe trap the sibling card names applies: git grep … | sed reports the pipe's exit status, not grep's.

⛔ Not a claim, not a dispatch — routing only.
