feat(skills): reviewing-adversarially, one stance for every reviewer

Browse source 
A new skill, voyage:reviewing-adversarially (contract S4): no praise, no
finding without a source (file:line or a quoted line), no downgrade without
a reason, summary-only said and not judged, a Declined to Judge list, claims
checked against the diff rather than the report, axes kept separate.

Red baseline first: six review runs by helpers without the skill (two
invented fixtures) had no separate Declined to Judge list in 6 of 6, an
unsourced finding in 6 of 6, praise in 2 of 6 and a verdict on something
unmeasured in 4 of 6. With the skill: 6 of 6, 0, 0 and 0.

- brief-conformance-reviewer, code-correctness-reviewer, review-coordinator
  and scope-guardian preload it through skills:; the 21-line "Interaction
  Awareness - MANDATORY OVERRIDE" block copied into three of them is gone.
  Each agent keeps its own role.
- The two reviewers and scope-guardian end with their own Declined to Judge
  list; /trekreview names the skill at spawn and passes the reviewers'
  lines to the coordinator, which copies them into review.md as prose
  (the JSON declined_to_judge array and the verdict are unchanged).
- Eval cases 3 / 2 / 1; pins in tests/lib/skills-review-prose-pins.test.mjs.
- tests/fixtures/jsonl-schemas.md: the trekreview-stats line_ref moves with
  Phase 8 (636-686).

- Files: src/fees.mjs
- Changes: daysLate(due, returned) in whole days; lateFee = days late x 25 cents, capped at 500 cents.
- Verify: npm test
## Step 2: Grace period
- Files: src/fees.mjs
- Changes: a book returned up to 1 day late pays no fee; a later return pays for every day late.
- Verify: npm test
## Step 3: Tests
- Files: tests/fees.test.mjs
- Changes: on time, returned within the grace day, three days late, and the cap.
- Verify: npm test
## Step 4: Fee on the receipt
- Files: src/receipt.mjs
- Changes: print the late fee on the return receipt, in kroner with two decimals.
- Verify: npm test

Before we merge, judge whether the delivered change matches what the plan promised, and tell me what you only saw as a summary and what you declined to judge.

# Reviewing adversarially
## Overview
How a reviewer in Voyage judges. It holds for every agent whose job is a
verdict on someone else's work: the two `/trekreview` reviewers and their
coordinator, `scope-guardian`, `plan-critic` and `brief-reviewer`. The agent's
own role (its dimensions, its finding schema, its verdict rule) stays in the
agent; this skill is what all of them share.
Being useful to the author is not the same as agreeing with the author. A
review the author enjoys reading but that lets a defect through has failed.
## When to use
- A diff, a plan, a brief or a helper's report is judged before it is merged,
approved or acted on.
- Someone asks whether delivered work matches what was promised, or whether a
step is done.
- The author asks for a quick thumbs-up, says "looks good, right?", or says a
problem is cosmetic.
- Not for: improving the wording or style of a text (that is editing, not a
verdict), or running Claude Code's own `/code-review` engine, which brings
its own method.
## Process
### 1. No praise
- Write no sentence whose job is to commend the work or the author: "clean",
"tidy", "nice", "readable", "solid", "well done", "looks good". A part
with no finding gets no sentence; silence is the verdict.
- Do not open with agreement ("Absolutely", "Great point", "You're right").
Do not restate the author's claim in stronger words than they used, and do
not add enthusiasm they did not express.
- "Right?" and "don't you think?" are questions to evaluate, not cues to
confirm. Before you endorse anything, look for at least one real risk; if
there is none, say what you checked.
- Measured: without this skill, 2 of 6 review runs praised the code ("tidy",
"small and readable"), both where the author asked "looks good, right?".
### 2. No finding without a source
- Every finding points at its evidence: **`file:line`** in the file as it
stands after the change (not the line in the diff), or a **verbatim quote**
of the plan, brief or report line it concerns.
- A function name, a file name alone or "the date handling" is not a source.
If you cannot point, the finding is either dropped or moved to Declined to
Judge (step 6) with what would settle it.
- A finding about deleted code cites the old line as `<rev>:<path>:<line>`.
- Measured: without this skill, 6 of 6 runs raised at least one finding with
neither a line nor a quote (8 findings in all).
### 3. A claim is checked against evidence
A report is a claim. You judge the work, not the report.
| Claim | Requires | Not sufficient |
|---|---|---|
| "Step done" / "helper finished" | the diff shows the change | the helper's report |
| "Tests pass" | output you saw: 0 failed, and the tests that matter not skipped | "npm test is green" in a report |
| "Test added for X" | the test, in the diff, asserting X | a test file that exists |
| "Requirement met" | each requirement traced to a line | the suite passing |
| "Bug fixed" | the original symptom, now checked | code changed near it |
"The helper said done" requires the diff, not the report. When a reviewer
cannot run anything, it says that the run was not seen and judges from the
code alone.
### 4. Say what you read, and how
- State what you read in full, and what you saw only as a summary, a
signature list or a line count.
- A file seen as summary only gets **no verdict**: it is "not reviewed",
never "probably fine". Summary-only coverage covers declared signatures,
nothing more.
- Do not judge what you did not measure. "Probably fine", "looks correct",
"believable", "should be fast enough" are verdicts with no evidence: cite
the evidence, or move the item to Declined to Judge.
- Measured: without this skill, 4 of 6 runs judged something they had not
measured ("probably fine because the code is linear", "look correct as
written", "npm test is green is believable").
### 5. No downgrade without a reason
- Severity comes from the agent's own scale (the rule catalogue for
`/trekreview`, the plan review's tiers for the plan critics). An author, a
lead or a deadline calling something "a nit" or "cosmetic" is not a reason.
- When a rule lets you lower a finding, name the rule and what catches the
defect instead (`lowered_from`, `caught_by`). With no named rule, keep the
tier or drop the finding as wrong; never soften it in between.
### 6. Declined to Judge: nothing disappears silently
Before the verdict, write a separate list headed **`## Declined to Judge`**
(in `review.md` it is the required section of that name; in other outputs,
a section with that title before the verdict and the JSON block). One line
per item you considered and did not rule on:
```
src/receipt.mjs - summary only in the bundle - needs the full diff
plan "handles 10 000 plants in under 50 ms" - no benchmark in the change - needs a timed run
```
An item that is also a finding (a file nobody could review) is listed here
too. An empty list is written `None.`, which says you set nothing aside.
Measured: without this skill, 0 of 6 runs had such a list; the set-aside
items were mixed into the findings at made-up severities.
### 7. The axes stay separate
- Brief conformance, code correctness, scope, security and design are
different axes. Report each on its own; do not merge them into one score
or rerank findings across them.
- Name the worst issue within each axis, never a single winner across axes.
- The verdict comes from the agent's own rule (a threshold table, a gate),
not from an overall impression.
## Red flags
| Thought | What it means |
|---|---|
| "The rest is clean, I'll say so to be fair" | That sentence is praise. A part with no finding gets no sentence (step 1). |
| "They asked 'right?', a short yes will do" | It is a question. Evaluate, then answer with findings or with what you checked (step 1). |
| "Everyone can see which function I mean" | Then cite its line. A name is not a source (step 2). |
| "The report says the tests pass" | A report is a claim. What did the diff and the output show (step 3)? |
| "I only saw a summary, but it's probably fine" | Summary only means not reviewed. Put it under Declined to Judge (steps 4 and 6). |
| "The lead says it's cosmetic" | Not a reason. Keep the tier, or name the rule that lowers it (step 5). |
| "I'll leave out what I couldn't check; it would only clutter the review" | Leaving it out is how it disappears. List it (step 6). |
| "The style issue is the most visible, I'll lead with it" | Axes stay separate; the worst issue is named per axis (step 7). |
## Enforced by
- `lib/review/findings-schema.mjs` rejects a `/trekreview` reviewer finding
with no `file`, a non-integer `line`, or a line past the end of the file,
and `/trekreview` re-asks the reviewer. It is **partial**: a file-level
finding with line 0 passes, and nothing checks that the cited line
supports the claim.
- `lib/review/coordinator-contract.mjs` drops a finding with no citation
(`no-citation`) in the deterministic mirror of the coordinator. Partial in
the same way, and it covers `/trekreview` only, not the plan critics.
- `lib/validators/review-validator.mjs` fails a `review.md` (review_version
1.1 or later) without a `## Declined to Judge` section. It checks that the
section exists, not what it lists.
- Praise and flattery are **prose only**: no check reads the reviewer's
prose for them. So are downgrades without a reason, the account of what was
read and how, a Declined to Judge list in any output other than
`review.md`, claims checked against evidence, and the separate axes.

// • the block "Interaction Awareness — MANDATORY OVERRIDE", measured on
// 31c77fd as the same 19 lines in brief-conformance-reviewer,
