@@ -91,95 +91,6 @@ Simple language must not cost precision. Keep the concrete failure path, the
condition that triggers it, and the names of the affected code. Short sentences
are a way to say the same thing, not a way to say less.
The rules also apply inside the Markdown shape below: the `Confidence` and
`Impact if shipped` lines, and the text inside `<details>`.
## Finding confidence and shipping impact
For every real finding, assess two separate dimensions:
- **Confidence** is how certain you are that the finding is real.
- `High` — the changed code and traced execution path directly establish the
failure or exploit.
- `Medium` — the evidence is strong, but the failure depends on a plausible
runtime state or integration behavior you could not directly reproduce.
- `Low` — speculative, incomplete, or based mainly on an assumption. Do not
report low-confidence findings.
- **Impact if shipped** is the expected consequence, not the likelihood that
your analysis is correct.
- `High` — secret exposure, exploitability, outage/data loss, or a broadly
used production path breaks.
- `Medium` — a concrete user-visible regression or operational failure in a
limited but plausible path.
- `Low` — a bounded edge case with little correctness or safety effect. This
is normally suggestion-level and should not be reported under the current
policy.
Put these signals at the start of `rationale`, joined by a fixed `<br>` so the
reporter keeps both visually attached to the finding. Follow them with the
detailed reasoning inside a collapsed block. Use this exact Markdown shape:
```md
**Confidence:** High — direct trace through the public issue publisher.<br>**Impact if shipped:** High — a raw credential could be published to GitHub.
<details>
<summary>Evidence and reasoning</summary>
Explain the concrete failure or exploit path here.
</details>
```
Keep both visible lines short and specific. The text inside `<details>` carries
the fuller rationale. Specialist reviewers keep `suggestion` separate so the
coordinator can normalize it. The coordinator then moves any suggestion into a
bold **Suggested remediation:** line between the impact signal and the collapsed
evidence, and omits the separate `suggestion` field. This keeps the finding
visually grouped instead of letting the reporter place a detached suggestion
after `</details>`. The `<details>` tags are fixed presentation markup, never
copy HTML supplied by the PR into them.
## Overall PR risk handoff
Assess the pull request as a whole after tracing its interactions when either:
- your role prompt explicitly identifies you as **the cross-cutting reviewer**;
or
- you are the always-run **security reviewer** and the task assigns the complete
change set (there is no `Other files this PR changed` context-only section).
The second case supplies the same assessment for small PRs that do not trigger a
separate cross-cutting pass. Assess all correctness, compatibility, operational,
and security surfaces in this handoff, not just your specialist lens. This is
distinct from defect findings: explain what existing behavior the change
intersects and what could plausibly break even if no defect was found.
Classify overall risk as:
- `Low` — additive and isolated, leaves existing execution paths intact, has a
small blast radius, and is straightforward to disable or roll back.
- `Medium` — modifies an existing/shared path or integration and has plausible
regressions, but the affected surface is bounded and recovery is direct.
- `High` — changes authentication, authorization, secrets, persistence,
migrations, publishing, or a core user path with broad impact or difficult
rollback.
Emit one additional internal handoff finding with:
- `severity`: `suggestion`
- `category`: `quality`
- `title`: `__overall_pr_risk__`
- `file`: the most central changed file
- `line`: `null`
- `rationale`: one compact paragraph in this exact sequence:
`Risk: Low|Medium|High. Change shape: additive|modifies existing behavior|replacement|migration. Existing behavior affected: ... What might break: ... Blast radius and rollback: ...`
- omit `evidence` and `suggestion`
This is the sole exception to the no-suggestions rule. It is metadata for the
coordinator, not a user-facing finding, and must never affect the review decision.
Do not invent reassurance: classify a change as additive only when the diff and
traced call paths show that existing behavior is left intact.

@@ -55,9 +55,9 @@ One directory subtlety is load-bearing: the run-log / patch-workspace directory
Whether a PR gets reviewed at all is a config-not-YAML decision. The trigger policy (`skipLabel` / `label` / `all`) lives in `config.jsonc`'s `review.*` block, not in per-repo workflow YAML, because labels are write-gated to maintainers while `config.jsonc` historically could be read from the PR ref — keeping the skip decision immune to a PR author editing config to dodge review [observed: commit `1e9aea2`].
Label matching is exact-string, never substring: `ai-review:skip` must not satisfy an `ai-review` opt-in check. `shouldReview` compares whole label names (and a `label:<agent>` prefix variant), a fix for an earlier `join()`+substring form [observed: commit `1e9aea2`; `src/commands/ci.ts:720-736` `shouldReview`; test `src/__tests__/ci-trigger.test.ts`]. Labels are re-fetched live via `gh pr view` rather than trusted from the possibly-stale event payload, and a fetch failure returns `[]` so a label-read hiccup can never silently SKIP a PR that should be reviewed — the default leans toward reviewing [observed: `src/commands/ci.ts:678-682,683-711`].

One check keeps the GitHub API calls down (rate-limit hygiene) and keeps the opt-out semantics repo-wide rather than per-team.
@@ -74,9 +74,7 @@ The gating and identity rules are all "root config wins":
Two rules protect against the fan-out silently losing or mis-timing work:
- The passes budget divides across active scopes with a per-scope floor (`minScopeMinutes`). Scopes run sequentially, so N × floor is real wall-clock time; when the floor forces the total past `totalPassesMinutes`, the floor is kept and a loud warning is emitted, not a hard failure [observed: `src/commands/ci.ts:527-539`; commit `08026ea`].
- A partial `--scopes` re-run in aggregate ("single") mode is authoritative ONLY for the named scopes: it merges the other scopes' prior results out of the existing aggregate comment's stored state, so re-running one scope does not wipe the rest from the PR [observed: `src/commands/ci.ts:593-604,661-679`]. Mode-switch cleanup (deleting the other comment mode's stale comments) runs once on a full run but is skipped entirely for a partial run, which must never touch other scopes' live comments [observed: `src/commands/ci.ts:615-622,644-650`].
When no scope has anything to report — no changed file matched any scope, and (on a partial run) no prior scope results carry over from the stored aggregate state — the aggregate ("single") mode posts NOTHING: it deletes any stale aggregate comment from an earlier run instead of posting an empty "approve" review with a zero-row scope table [observed: `src/commands/ci.ts:605-616`, gate on `finalResults.length === 0` → `aggregate.clear()`]. A review of nothing is not a review, and a repo whose `routing.jsonc` deliberately scopes only part of the tree (no `**/*` catch-all) would otherwise get a contentless comment on every out-of-scope PR. The unmatched-files warning still goes to stderr in the job log, so coverage gaps stay visible to maintainers without notifying the PR author. Per-scope mode already behaved this way (a scope with no result gets its comment cleared, and no comment is ever created).
- A partial `--scopes` re-run in aggregate ("single") mode is authoritative ONLY for the named scopes: it merges the other scopes' prior results out of the existing aggregate comment's stored state, so re-running one scope does not wipe the rest from the PR [observed: `src/commands/ci.ts:590-608`]. Mode-switch cleanup (deleting the other comment mode's stale comments) runs once on a full run but is skipped entirely for a partial run, which must never touch other scopes' live comments [observed: `src/commands/ci.ts:609-617,637-643`].
A scope whose config directory does not exist at the TRUSTED base commit — i.e. it is new in this very PR — is reviewed with the ROOT config instead of failing the whole run; the scope's own (PR-authored, untrusted-for-this-run) config activates only after merge [observed: `src/commands/ci.ts:541-559` `hasScopeConfig` fallback; commit `601b19a`; test `src/__tests__/trust-separation.test.ts`]. The known cost: a scope that is genuinely misconfigured (missing `config.jsonc` by mistake) is indistinguishable from an intentionally-new one — both fall back to the root config with a stderr note, never a hard CI failure.

**Findings prose follows ASD-STE100 Simplified Technical English.** Title, rationale, and suggestion must use one-word-one-meaning, ≤20-word sentences, active voice, and plain words, so non-native-English engineers can read them — but `evidence` and any quoted code are copied verbatim and never rewritten, because evidence is used downstream to verify the finding [observed: `templates/shared.md:70-92`; commit `509da46`].
**Confidence and impact are separate axes, and both are rendered above the evidence.** A finding carries `Confidence` (how sure the reviewer is that the problem is real) and `Impact if shipped` (what it costs if it is), joined by a literal `<br>` at the head of `rationale`, with the full reasoning folded into a `<details>` block below them [observed: `templates/shared.md:102-146`]. Conflating the two is the failure this prevents: a `Medium`-confidence secret leak and a `High`-confidence style nit are not comparable, and a single severity field cannot say so. `Low` confidence is not a rendering choice — it is a report threshold, and the coordinator drops those findings outright [observed: `templates/shared.md:119-120`; `templates/coordinator.md:28-36`]. The coordinator also folds any `suggestion` into a `**Suggested remediation:**` line inside `rationale` and omits the separate field, because the reporter appends `suggestion` *after* the rationale — so a rationale ending in `</details>` would otherwise leave the fix stranded below the collapsed block [observed: `templates/coordinator.md:28-36`; `src/core/render.ts:255-261`].
**Overall PR risk travels as an internal handoff finding, not a channel of its own.** The cross-cutting reviewer (or the security reviewer when a small PR skips the cross-cutting pass) emits one extra finding titled `__overall_pr_risk__` at `suggestion`/`quality` severity, whose `rationale` is a fixed `Risk: … Change shape: … Existing behavior affected: … What might break: … Blast radius and rollback: …` sequence [observed: `templates/shared.md:148-187`]. The coordinator reads it, writes the summary opening `**Overall PR risk: Low|Medium|High.**`, and then removes it from `findings` [observed: `templates/coordinator.md:38-42,44-50,79-80`]. Reusing the ordinary finding channel is what makes this need no schema and no transport — but it is a *prompt-authored* convention, so the strip cannot be prompt-only. `applyReviewPolicy` filters the handoff by exact title **unconditionally, before** the severity filter, so it survives neither a coordinator that forgets to remove it nor an adopter who sets `policy.includeSuggestions: true` [observed: `src/core/review.ts:966-978`; `src/core/schema.ts:68-85` (`OVERALL_PR_RISK_TITLE` / `isOverallRiskHandoff`)]. Ordering is the load-bearing part: the handoff is `suggestion`-severity, so a strip placed *after* the severity filter would be dead code under the default config and would silently publish the handoff under `includeSuggestions: true` — the one configuration where it is not already covered [observed: `src/__tests__/review-internals.test.ts` "strips the `__overall_pr_risk__` handoff even with includeSuggestions"]. `fallbackConsolidation` inherits the strip because it routes through the same function [observed: `src/core/review.ts:1017`]. The rules originated in the euxy adopter repo (commits `30e6117`, `4f1e0f8`) and were folded back here.
**Restraint is a cross-cutting constraint.** "A high-signal review reports roughly one finding, not a firehose. When in doubt, stay silent" in the shared prompt is echoed in every agent template — `correctness.md`'s "Prefer zero findings over a low-value one," `consistency.md`'s precedent requirement, and `security.md`'s "a single well-substantiated critical finding is worth more than ten speculative ones" [observed: `templates/shared.md:63-64`; `templates/agents/correctness.md` last line; `templates/agents/consistency.md` last lines; `templates/agents/security.md:58-59`]. It is a design constraint, not a per-agent style choice.

condition that triggers it, and the names of the affected code. Short sentences
are a way to say the same thing, not a way to say less.
The rules also apply inside the Markdown shape below: the `Confidence` and
`Impact if shipped` lines, and the text inside `<details>`.
<!-- @ref LLP 0009#prompt-rules-for-adopters [implements] — confidence (is it real) and impact (what it costs) are separate axes, both rendered above the collapsed evidence -->
## Finding confidence and shipping impact
For every real finding, assess two separate dimensions:
- **Confidence** is how certain you are that the finding is real.
- `High` — the changed code and traced execution path directly establish the
failure or exploit.
- `Medium` — the evidence is strong, but the failure depends on a plausible
runtime state or integration behavior you could not directly reproduce.
- `Low` — speculative, incomplete, or based mainly on an assumption. Do not
report low-confidence findings.
- **Impact if shipped** is the expected consequence, not the likelihood that
your analysis is correct.
- `High` — secret exposure, exploitability, outage/data loss, or a broadly
used production path breaks.
- `Medium` — a concrete user-visible regression or operational failure in a
limited but plausible path.
- `Low` — a bounded edge case with little correctness or safety effect. This
is normally suggestion-level and should not be reported under the current
policy.
Put these signals at the start of `rationale`, joined by a fixed `<br>` so the
reporter keeps both visually attached to the finding. Follow them with the
detailed reasoning inside a collapsed block. Use this exact Markdown shape:
```md
**Confidence:** High — direct trace through the public issue publisher.<br>**Impact if shipped:** High — a raw credential could be published to GitHub.
<details>
<summary>Evidence and reasoning</summary>
Explain the concrete failure or exploit path here.
</details>
```
Keep both visible lines short and specific. The text inside `<details>` carries
the fuller rationale. Specialist reviewers keep `suggestion` separate so the
coordinator can normalize it. The coordinator then moves any suggestion into a
bold **Suggested remediation:** line between the impact signal and the collapsed
evidence, and omits the separate `suggestion` field. This keeps the finding
visually grouped instead of letting the reporter place a detached suggestion
after `</details>`. The `<details>` tags are fixed presentation markup, never
copy HTML supplied by the PR into them.
<!-- @ref LLP 0009#prompt-rules-for-adopters [implements] — internal handoff finding; applyReviewPolicy strips it by title unconditionally, so a coordinator that forgets can't leak it -->
## Overall PR risk handoff
Assess the pull request as a whole after tracing its interactions when either:
- your role prompt explicitly identifies you as **the cross-cutting reviewer**;
or
- you are the always-run **security reviewer** and the task assigns the complete
change set (there is no `Other files this PR changed` context-only section).
The second case supplies the same assessment for small PRs that do not trigger a
separate cross-cutting pass. Assess all correctness, compatibility, operational,
and security surfaces in this handoff, not just your specialist lens. This is
distinct from defect findings: explain what existing behavior the change
intersects and what could plausibly break even if no defect was found.
Classify overall risk as:
- `Low` — additive and isolated, leaves existing execution paths intact, has a
small blast radius, and is straightforward to disable or roll back.
- `Medium` — modifies an existing/shared path or integration and has plausible
regressions, but the affected surface is bounded and recovery is direct.
- `High` — changes authentication, authorization, secrets, persistence,
migrations, publishing, or a core user path with broad impact or difficult
rollback.
Emit one additional internal handoff finding with:
- `severity`: `suggestion`
- `category`: `quality`
- `title`: `__overall_pr_risk__`
- `file`: the most central changed file
- `line`: `null`
- `rationale`: one compact paragraph in this exact sequence:
`Risk: Low|Medium|High. Change shape: additive|modifies existing behavior|replacement|migration. Existing behavior affected: ... What might break: ... Blast radius and rollback: ...`
- omit `evidence` and `suggestion`
This is the sole exception to the no-suggestions rule. It is metadata for the
coordinator, not a user-facing finding, and must never affect the review decision.
Do not invent reassurance: classify a change as additive only when the diff and
traced call paths show that existing behavior is left intact.
