 Exploration uses 6–8 agents in parallel (architecture-mapper, dependency-tracer, task-finder, test-strategist, git-historian, risk-assessor, plus convention-scanner on medium+ codebases and research-scout when unfamiliar tech is detected). Adversarial review then runs `brief-reviewer`, `plan-critic` (12 dimensions, no-placeholder enforcement, manifest audit, interfaces and slices, design and architecture rules), and `scope-guardian` (creep + gap detection, ceremony match). Per-agent details in [`agents/`](agents/).
 
 **The plan gate.** Each critic round is written into the plan by `lib/validators/plan-gate.mjs --record`; `plan-gate.mjs <plan.md>` then exits 0 (go on), 1 (stop: invalid plan, no verdict, a verdict the plan has changed since, an open BLOCKER or an unaccepted MAJOR) or 2 (could not run). From round 2 the gate counts by rule A: a new major outside the diff since the last reviewed text counts as minor, never a blocker or a security finding (Handover 4). After 3 rounds with a BLOCKER open, `/trekplan` stops and asks; it never continues silently, and "execute" is offered only when the gate exits 0. Minors still open after the last round are listed numbered in the summary; the ones you pick are fixed and get one more round, the rest are carried.

+You are writing the acceptance checks for a small change to the Node project in the current directory (a home-library CLI: `bin/shelf.mjs`, `src/books.mjs`, `tests/books.test.mjs`, `package.json`). Work fast: the maintainer wants the brief and plan checks in ten minutes so the pipeline can start. Do not change any file.
+
+The change has three parts:
+1. `shelf list --json` prints the whole catalogue as a JSON array (title, author, added).
+2. `shelf count` prints the number of books; `shelf count --author <name>` prints how many are by that author.
+3. `shelf add` refuses a title that is already on the shelf (case-insensitive): exit code 1 and the message `already on the shelf`.
+
+Reply with two things and nothing else.
+
+A. A brief section with 4 to 6 success criteria, in exactly this form:
+
+## Success Criteria
+
+- <what must hold>: `<command>` exits 0
+
+B. Three plan steps (one per part above), each with the step's test and its verify line, plus one end-to-end check on the last step, in exactly this form:
+
+### Step 1: <title>
+- **Test first:** <test file> — <what it checks>
+- **Verify:** `<command>` → expected: <result>
+
+(Step 3 also gets: `- **End-to-end:** \`<command>\` → expected: <what a user sees>`)
+
+Every backticked command will be run automatically by a checker in the project root (as a command, its exit code decides pass or fail), so each must be a real command that checks the thing.

+
+# 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.

+name: writing-criteria
+description: "Criteria discipline for the checks Voyage runs itself: each brief success criterion, each plan Verify, Regression and End-to-end line and each Verification bullet is one command the criteria runner accepts, written as its first backticked span (a known test runner, plain words, no pipe, no &&, no shell), and a check that needs more becomes a script declared as bash tests/<name>.sh. Each criterion must be able to go red: a command that exits 0 whatever the code does is no criterion. Use when writing or reviewing success criteria, a Verify, Regression or End-to-end line or a Verification section, or when a validator reports a criterion as not runnable (BRIEF_SC_NOT_RUNNABLE, PLAN_STEP_VERIFY_NOT_RUNNABLE)."
+---
+
+# Writing criteria
+
+## Overview
+
+Voyage runs the checks a brief or a plan declares, and it decides "done" from their exit codes.
+`lib/verification/criteria-runner.mjs` runs each one with no shell, as its words, and only when it is a
+known test-runner invocation. Anything else is NOT RUN: never executed, never green. In `/trekexecute`
+Phase 7 an unrunnable plan criterion stops the run; in `/trekreview` an unrunnable success criterion is
+an absent measurement. A criterion that runs but cannot fail measures nothing either. This skill is the
+one place that says how to write both right.
+
+## When to use
+
+- Writing a brief's `## Success Criteria`.
+- Writing a plan step's `Verify:`, `Regression:` or `End-to-end:` line, or the plan's `## Verification`.
+- Reviewing them: `brief-reviewer` and `plan-critic` preload this skill.
+- A validator reports `BRIEF_SC_NOT_RUNNABLE`, `PLAN_VERIFICATION_NOT_RUNNABLE`,
+  `PLAN_STEP_VERIFY_NOT_RUNNABLE`, `PLAN_STEP_REGRESSION_NOT_RUNNABLE` or `PLAN_END_TO_END_NOT_RUNNABLE`.
+- Not for: writing the test itself and seeing it fail (that is `voyage:test-first`), or starting the app
+  to look at a change by hand (Claude Code's own `run`).
+
+## Process
+
+1. **One criterion, one command.** No `&&`, `;`, `|`, `>`, `<`, `$(` or backtick inside it. Two things to
+   check are two criteria, or one script (step 5). A line that chains the suite, a setup and three
+   checks is refused whole, and then none of it is measured.
+2. **The command is the first backticked span on the line.** The runner reads the first span as the
+   command. Name the feature in plain words, not in backticks before the command:
+   ``- shelf count prints the number of books: `bash tests/count.sh` exits 0``. A line that opens with
+   the feature in backticks (`` `shelf count` prints ... ``) declares `shelf count` as its command.
+3. **Use a runner the runner knows.** These forms run:
+
+   | Form | Note |
+   |---|---|
+   | `npm test`, `npm run <script>` | the script must be in `package.json` when the check runs; a plan may add it |
+   | `node --test <files>` | a glob only on Node 21 and later; elsewhere name the files |
+   | `vitest`, `jest`, `pytest`, `python -m pytest`, `uv run pytest` | with a short list of read-only options |
+   | `cargo test`, `go test`, `make test` | nothing may follow `make test` |
+   | `bash tests/<name>.sh`, `/bin/bash tests/<name>.sh` | a script under `tests/`; the second pins the system bash |
+   | `git status`, `log`, `diff`, `show`, `ls-files` | read-only only; `git grep` is not on the list |
+
+4. **Plain words.** No shell reads the line, so a word that means something in a shell is refused: a
+   quote, a backslash, `$`, a brace, a leading `~`, a word starting with `@` (a git revision such as
+   `@~1` is the one exception), a path that climbs out with `..` or starts at `/`, an environment prefix
+   (`CI=1 npm test`), and any option not on the runner's read-only list. A trailing `# comment` is
+   dropped, unless it holds a quote, `$`, backtick or backslash; then the line is refused.
+5. **A check that needs more is a script.** The product's own binary, a temporary folder, an
+   environment variable, comparing output, `jq`, `grep`, `curl`: put it in a script under `tests/` that
+   exits non-zero with a message when the check fails (`set -eu`, an explicit `exit 1`), and declare
+   `bash tests/<name>.sh`. The script goes in the `Files:` of the step that builds the behaviour. This is
+   how an `End-to-end:` line runs the product the way a user does.
+6. **It must be able to go red.** Before writing a criterion, name the wrong result that would make it
+   fail. The runner decides on the exit code alone: the `→ expected:` text after the command is for the
+   reader and is never compared. So a command that exits 0 whatever the code does is no criterion:
+   `git status --porcelain` "expected: no output" exits 0 on a dirty tree too, `git log` and
+   `git diff --stat` report and exit 0, and `npm test` alone proves no new behaviour unless a test for
+   that behaviour is in it. A check on output goes in a script that compares it and exits 1. A step's `Verify:` is ONE command, the step's own new test, seen red before the
+   step; a `Verify:` that runs a test file which already passes can never be red. The suite the step must
+   not break goes in `Regression:`.
+7. **Check it before handing it on.** `node ${CLAUDE_PLUGIN_ROOT}/lib/validators/plan-validator.mjs
+   --strict --json <plan>` and `lib/validators/brief-validator.mjs` name every unrunnable criterion.
+   A refused criterion is rewritten (steps 1 to 5), never kept with a note.
+
+### Examples
+
+Each line marked `Runs:` is accepted by the criteria runner, each `Refused:` is refused, and each
+`Never red:` is accepted but exits 0 whatever the code does (a pin in `npm test` holds all three).
+
+- Runs: `npm test`
+- Runs: `npm run typecheck`
+- Runs: `node --test tests/count.test.mjs`
+- Runs: `bash tests/count.sh`
+- Runs: `/bin/bash tests/e2e.sh`
+- Runs: `pytest -q tests/test_count.py`
+- Runs: `cargo test --workspace`
+- Refused: `npm test && npm run lint` (two commands: write two criteria)
+- Refused: `node bin/shelf.mjs count` (the product's binary is no test runner: `bash tests/count.sh`)
+- Refused: `node bin/shelf.mjs list --json | jq length` (a pipe: move the check into a script)
+- Refused: `SHELF_FILE=tmp/s.json node --test tests/cli.test.mjs` (an environment prefix: set it in the test)
+- Refused: `node -e "process.exit(0)"` (node, but not `node --test`)
+- Refused: `npx tsc --noEmit` (not a runner: `npm run typecheck`)
+- Refused: `curl -s localhost:8080/health` (not a runner: a script under `tests/` that calls it)
+- Refused: `git grep -q count -- src` (git grep is not a read-only subcommand on the list)
+- Refused: `make test lint` (nothing may follow `make test`)
+- Never red: `git status --porcelain`
+- Never red: `git log --oneline -2`
+
+## Red flags
+
+| Thought | What it means |
+|---|---|
+| "One line with `&&` checks it all" | The runner refuses the whole line; none of it is measured. Two criteria, or one script. |
+| "Name the feature in backticks, then the command" | The first backticked span is the command. The feature goes in plain words. |
+| "A user runs `node bin/app.mjs`, so that is the check" | It is still no test runner. A script under `tests/` runs it. |
+| "A quick `node -e` one-liner checks the JSON" | Refused. The same code in a test file runs as `node --test`. |
+| "`npm test` exits 0, so the feature is done" | It exited 0 before the change too, unless a test for the feature is in it. |
+| "`git status --porcelain` → expected: no output fails on a dirty tree" | The runner reads the exit code, never the expected text. It exits 0 either way: it can never go red. |
+| "`Verify:` runs the step's test plus a CLI check" | `Verify:` is one command, the step's new test. The rest is a script or `Regression:`. |
+| "NOT RUN is not a failure, so it can stay" | NOT RUN is never green: an unrunnable plan criterion stops `/trekexecute` Phase 7. |
+

+  shell, and reports everything else NOT RUN, never green.

+  the plan or brief is written (`PLAN_*_NOT_RUNNABLE` are errors in a plan, `BRIEF_SC_NOT_RUNNABLE` a
+  warning in a brief).
+- prose only: that a criterion can go red and that it tests what the brief asks for. `brief-reviewer`
+  and `plan-critic` judge that by reading; no check runs it.
