# Ultrareview Local v1.0

Independent post-hoc review of code delivered by `/trekexecute`
against the contract in `brief.md`. Produces `review.md` — a structured
artifact with severity-tagged findings that `/trekplan --brief
review.md` can consume as plan input (Handover 6).

Pipeline position:

```
/trekbrief     →  brief.md
/trekresearch  →  research/*.md
/trekplan      →  plan.md
/trekexecute   →  progress.json (+ commits)
/trekreview    →  review.md            (this command)
```

The review is **independent**: each reviewer runs without cross-feeding,
and the coordinator applies BOUNDED operations only. Synthesis-level
inference across files is forbidden in v1.0 (Judge Agent pattern).

See `agents/review-orchestrator.md` for the canonical workflow this
command executes inline.

## Phase 1 — Parse mode and validate input

Parse `$ARGUMENTS` via the shared arg-parser:

```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/parsers/arg-parser.mjs --command trekreview "$@"
```

The parser recognizes these flags (see `lib/parsers/arg-parser.mjs`
FLAG_SCHEMA `trekreview` entry):

| Flag | Type | Purpose |
|------|------|---------|
| `--project <dir>` | valued | Required. Path to trekplan project folder containing `brief.md`. |
| `--since <ref>` | valued | Optional. Override "before" SHA for the diff. Validated via `git rev-parse --verify`. |
| `--quick` | boolean | Skip the brief-conformance pass; run only the code-correctness reviewer; skip the coordinator's reasonableness filter. |
| `--validate` | boolean | Schema-only check on existing `{project_dir}/review.md`. No LLM calls. |
| `--dry-run` | boolean | Print the discovered scope and triage map. Skip writes. |
| `--fg` | boolean | No-op alias (foreground is default). |
| `--workflow` | boolean | **(opt-in, NW2)** Run Phase 5–6 on the bake-off-validated Workflow substrate (`scripts/trekreview-armB.workflow.mjs`) instead of the default prose Agent-tool path. Requires **Claude Code 2.1.154+**. Combines with `--quick`. See *§ Phase 5–6 via the Workflow substrate*. |

Resolution:
1. If `--project` is missing, print usage and stop:
   ```
   Error: --project <dir> is required.
   Usage: /trekreview --project <dir> [--since <ref>] [--quick] [--validate] [--dry-run]
   ```
2. Trim trailing slash from `{dir}`. Set:
   - `project_dir = {dir}`
   - `brief_path = {dir}/brief.md`
   - `review_path = {dir}/review.md`
3. If `{dir}` does not exist or `{dir}/brief.md` is missing:
   ```
   Error: project directory not initialized. Run /trekbrief first.
   Missing: {dir}/brief.md
   ```

Set `mode`:
- `validate` if `--validate` is set (overrides everything else; skip to Phase 8.5).
- `dry-run` if `--dry-run` is set.
- `quick` if `--quick` is set.
- `default` otherwise.

Set `workflow_substrate` (orthogonal to `mode` — a substrate choice, not a behavior mode):
- `true` if `--workflow` is set — Phase 5–6 run on the Workflow substrate (see the Phase 5
  routing gate). The Workflow tool requires **Claude Code 2.1.154+**; if it is unavailable,
  fall back to the prose path and note the fallback in the Executive Summary.
- `false` otherwise. **Default stays prose**: the substrate is opt-in, so the lower
  portability floor of the prose path is preserved unless the operator opts in.

## Phase 2 — Validate brief

Run the brief validator in soft mode — the brief is upstream context, not
something this command produces, so partial grades are acceptable as long
as the file is parseable:

```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/validators/brief-validator.mjs --soft --json "{brief_path}"

# v5.1.1 — resolve the review-phase brief signal. The JSON is captured as
# phase_signal_result and used in Phase 7 at the reviewer-launch site to
# inject the brief-resolved model.
node ${CLAUDE_PLUGIN_ROOT}/lib/profiles/phase-signal-resolver.mjs --brief "{brief_path}" --phase review --json
```

Read the JSON output. If `valid: false` AND any error has code
`BRIEF_MISSING_REQUIRED_FIELD` or `FRONTMATTER_PARSE_ERROR`: stop and
ask the user to re-run `/trekbrief`. Other soft errors become
warnings in the review's Executive Summary.

Read the brief frontmatter. Capture for review.md:
- `task` → review frontmatter `task`
- `slug` → review frontmatter `slug`
- `project_dir` → review frontmatter `project_dir` (defaults to the
  CLI `--project` value when missing)

## Phase 3 — Discover scope SHA range

Determine the "before" SHA that bounds the review:

1. **`--since <ref>` override** — if set, validate via:
   ```bash
   git rev-parse --verify "$since_ref"
   ```
   On failure: print `Error: --since ref is not a valid git revision: {ref}` and stop.
   Set `before_sha = $(git rev-parse --verify "$since_ref")`.

2. **Preferred path** — read `{project_dir}/progress.json` if it exists.
   Extract `session_start_sha`. Validate it via `git rev-parse --verify`.
   Set `before_sha = session_start_sha`.

3. **Fallback** — no `progress.json`. Use the brief's mtime to find the
   most recent commit at or before the brief was written:
   ```bash
   brief_mtime=$(stat -f %m "{brief_path}")  # macOS; on Linux use stat -c %Y
   before_sha=$(git log --until="@$brief_mtime" -n 1 --format=%H)
   ```
   Emit a clear warning that gets surfaced in the review's Executive
   Summary: "scope_sha_start unavailable — falling back to brief mtime
   ({timestamp}). Coverage may include unrelated commits."

Compute the "after" SHA: `after_sha=$(git rev-parse HEAD)`.

Capture working-tree changes (uncommitted at review time):
```bash
git diff --name-only "$before_sha".."$after_sha"
git diff --name-only HEAD       # uncommitted (annotated [uncommitted])
```

The combined file list is the review scope. Note that the
`[uncommitted]` annotation is a **brief-level contract** — the brief's
Assumptions section declares this is allowed; the review surfaces it
explicitly in the Coverage table.

If the file count is `0`, write a one-line review.md noting "No diff
between {before_sha} and {after_sha}; nothing to review." Verdict: ALLOW.
Skip Phases 4–7. Continue to Phase 8 (validate + stats).

## Phase 4 — Triage gate (deterministic path-pattern classifier)

The triage gate is **deterministic** — no LLM judgment. It classifies
every file from Phase 3 into a treatment bucket:

| Treatment | When |
|-----------|------|
| `skip` | Matches `*.lock`, `*.svg`, `dist/**`, `build/**`, `node_modules/**`, OR the file's first 3 lines contain a generated-file marker (`@generated`, `Code generated by`, `DO NOT EDIT`). |
| `deep-review` | Matches `auth/**`, `crypto/**`, `**/security/**`, `hooks/**`. |
| `summary-only` | Default treatment for everything else. |

Hard refuse-with-suggestion gates — use `AskUserQuestion`:

```
if (reviewed_files_count > 100) → ask user
if (estimated_diff_tokens > 100000) → ask user
```

Token estimation: `wc -c "$diff_file" / 4` (rough proxy). Use
`AskUserQuestion` with the prompt:

> The diff under review is large (`{N}` files / `~{T}` tokens). Continue
> with the full scope, narrow with `--since <closer-ref>`, or stop?

Options:
1. **Continue** — proceed at this scope.
2. **Narrow** — print suggested `git log --oneline {before}..HEAD` so the
   user can pick a closer ref, then stop.
3. **Stop** — cancel.

Record the treatment for every file. Files marked `skip` MUST appear in
the Coverage section of `review.md` — never silently drop them. Silent
drops are `COVERAGE_SILENT_SKIP` (MAJOR) per the rule catalogue.

If `mode == dry-run`: print the triage map and exit.

## Phase 5 — Launch parallel reviewers

**Substrate routing (opt-in `--workflow`).** When `workflow_substrate == true`, run
Phases 5–6 via the Workflow substrate documented in *§ Phase 5–6 via the Workflow
substrate* (below Phase 6), then resume at Phase 7 with the returned
`{verdict, findings}`. When `false` (the default), run the prose Agent-tool path
described in the rest of this phase.

Launch two reviewer agents **in parallel** via the Agent tool — one
message, multiple tool calls.

Reviewers run independently. Do NOT pre-feed findings between them.

| Agent | Mode-gated | Purpose |
|-------|------------|---------|
| `brief-conformance-reviewer` | Skipped in `quick` | Trace each Success Criterion + Non-Goal to delivered code. Emits findings tagged with rule_keys from the conformance/scope categories. |
| `code-correctness-reviewer` | Always runs | 7-dimension code review. Emits findings tagged with rule_keys from the correctness/security/maintenance/tests categories. |

Each reviewer prompt includes:
- **Diff context** — the unified diff from Phase 3, truncated per file
  for files marked `summary-only`.
- **Triage map** — full file list with treatments. Reviewers must
  respect `skip` decisions.
- **Brief path** — `{brief_path}` (read on demand; do not inline).
- **Rule catalogue** — reference to `lib/review/rule-catalogue.mjs`.

Collect each reviewer's trailing JSON block and **validate it against the
reviewer-output schema** rather than merely parsing it. Run:

```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/review/findings-schema.mjs --json <reviewer-output-file>
```

`validateReviewerOutput` in `lib/review/findings-schema.mjs` extracts the
last fenced `json` block, parses it, and schema-checks every finding
(load-bearing fields: `file`, `rule_key` ∈ catalogue, `severity` ∈ enum,
`line` integer ≥ 0). Parse failure and schema failure surface through the
same stable error codes (`FINDINGS_NO_JSON_BLOCK`, `FINDINGS_PARSE_ERROR`,
`FINDING_*`).

On any failure, re-ask **that reviewer** to re-emit a conforming JSON
block only — quote the reported error codes/locations so the fix is
targeted. **Bounded retries: N=2.** If the output still fails after 2
re-asks, stop and report which reviewer produced non-conforming output;
do not feed unvalidated findings to the coordinator.

In `quick` mode, launch only `code-correctness-reviewer`. The Executive
Summary will note the brief-conformance pass was skipped.

## Phase 6 — Coordinator dedup + verdict

Launch `review-coordinator` (Agent tool) with the merged findings array
from Phase 5 plus the triage map, brief metadata, and SHA range.

The coordinator runs the 4-pass process documented in
`agents/review-coordinator.md`:

1. **Dedup** by `(file, line, rule_key)` triplet.
2. **HubSpot Judge filters** — Succinctness, Accuracy, Actionability.
3. **Cloudflare reasonableness** — drop speculative or catalogue-violating
   findings (skipped in `quick` mode).
4. **Verdict** — BLOCK / WARN / ALLOW per the threshold table.

The coordinator's output is the full review.md content — frontmatter +
body sections + trailing JSON block. Do NOT re-run the reviewers based
on the coordinator's output.

## Phase 5–6 via the Workflow substrate (opt-in `--workflow`)

Runs **only** when `workflow_substrate == true`. This is the **NW2 port**: it expresses
the SAME Phase 5–6 pipeline (parallel reviewers → triplet-dedup → coordinator verdict) as
a single Workflow, reusing the NW1 findings schema. The S10 bake-off found it
**fidelity-equivalent** to the prose path — see `docs/T2-bakeoff-results.md` (verdict
**POSITIVE**: verdict-match 1.0, issue-coverage 100%, `(file,rule_key)` jaccard ≥
within-arm, tokens +4.4%). It stays **opt-in**, not the default, because the Workflow tool
raises the consumer floor to **Claude Code 2.1.154+** (outward-facing; the prose path
keeps the lower floor).

Invoke the port via the **Workflow** tool with the Phase 1–4 output pinned into `args`:

```
Workflow({
  scriptPath: "${CLAUDE_PLUGIN_ROOT}/scripts/trekreview-armB.workflow.mjs",
  args: {
    briefPath: "{brief_path}",
    diffPath:  "{path to the unified diff file from Phase 3}",
    triage:    "{triage map as 'path → treatment' lines from Phase 4}",
    quick:     {true if mode == quick, else false}
  }
})
```

Contract (verified in S10 part B — follow exactly):
- **Pass `args` as a JSON object.** The script defensively re-parses a JSON *string*, but
  the object form is the contract.
- **Reviewers are `StructuredOutput`-schema-forced** — `rule_key` is enum-enforced at the
  tool layer (stronger than the prose path's post-hoc NW1 check), so there is no
  `JSON.parse`/re-ask dance.
- **Recover the result from the `RESULT_JSON:{…}` line** inside the workflow output logs.
  The script returns `{verdict, findings, ...}` AND logs it as that line; the
  notification's `<result>` may be truncated, so parse the logged line.
- The reviewer/coordinator agentTypes are namespaced inside the script
  (`voyage:brief-conformance-reviewer`, `voyage:code-correctness-reviewer`,
  `voyage:review-coordinator`).

Then continue at **Phase 7** exactly as the prose path does — Phase 7 rendering, Phase 8
validation, and the operator gate are **shared** and substrate-independent (both paths
return the same `{verdict, findings}` shape).

**Known limitation (per bake-off §Posture, surfaced not hidden).** Classifier interference
was measured **0** at 9-agent concurrency in the session's default permission mode; an
explicit `auto`/`bypass`-mode re-run was not performed (the permission mode is operator-set,
not settable from within a session). trekreview's small fan-out showed 0 interference in S8
and S10. The large fan-out case (the trekplan swarm) is out of NW2 scope.

## Phase 7 — Write review.md

Write the coordinator's output verbatim to:

```
{project_dir}/review.md
```

Create parent directories if they do not exist. Atomic write pattern:
write to a temp file, then rename. The frontmatter `findings:` field
must use **block-style YAML** (one ID per line, `  - ` prefix). The
parser at `lib/util/frontmatter.mjs` does not support flow-style arrays.

If `mode == dry-run`: skip the write; print the would-be path and the
first 60 lines of the rendered output.

## Phase 8 — Validate output + stats

Run the strict validator:

```bash
node ${CLAUDE_PLUGIN_ROOT}/lib/validators/review-validator.mjs --json "{review_path}"
```

If validation fails:
- For repairable errors (missing required body section, malformed
  finding-ID, REVIEW_VERSION_FORMAT warning): repair in place — re-emit
  the missing section, recompute the finding-ID, fix the version
  string. Re-validate.
- For unrepairable errors (REVIEW_WRONG_TYPE, malformed frontmatter):
  stop and ask the user to re-run; do not silently produce an invalid
  review.md.

Append a stats line to `${CLAUDE_PLUGIN_DATA}/trekreview-stats.jsonl`
(create the file if it does not exist):

```json
{"ts":"{ISO-8601}","slug":"{slug}","verdict":"BLOCK|WARN|ALLOW","counts":{"BLOCKER":N,"MAJOR":N,"MINOR":N,"SUGGESTION":N},"reviewed_files_count":N,"mode":"default|quick|validate|dry-run","duration_ms":N}
```

If `${CLAUDE_PLUGIN_DATA}` is unset or not writable, skip stats silently.
Never let stats failures block the main workflow.

**Build the operator-annotation HTML.** After stats land, run:

```bash
ANNOT_HTML=$(node ${CLAUDE_PLUGIN_ROOT}/scripts/annotate.mjs "{review_path}" 2>&1)
```

`stdout` is the absolute path to the `.html` on success. The HTML renders
`review.md` with line numbers, lets the operator click any line to attach
their own note (not Claude-generated suggestions — the operator drives
every annotation), keeps a sidebar of all notes, persists state in
localStorage, and exposes a "Copy Prompt" button. If `annotate.mjs`
exits non-zero, surface a one-line warning and continue — the annotation
HTML is a convenience, not a gate.

## Phase 8.5 — Validate-only mode (`--validate`)

When `mode == validate`:
1. Skip Phases 3–7 entirely.
2. Run the strict validator on `{project_dir}/review.md`.
3. Print a one-line PASS/FAIL summary plus the JSON output on FAIL.
4. Exit 0 on PASS, 1 on FAIL. Never write to disk. Never call any agent.

## Phase 9 — Present summary

After the write succeeds, print:

```
## Ultrareview Complete

**Task:** {task}
**Mode:** {default | quick | dry-run}
**Brief:** {brief_path}
**Project:** {project_dir}
**Review:** {review_path}
**Annotation HTML:** file://{$ANNOT_HTML}
**Scope:** {before_sha}..{after_sha} ({reviewed_files_count} files)
**Verdict:** {BLOCK | WARN | ALLOW}

### Counts
- BLOCKER: {N}
- MAJOR: {N}
- MINOR: {N}
- SUGGESTION: {N}

### Top findings
- [{severity}] {title} ({file}:{line})
  ...
{up to 5 highest-severity findings}

────────────────────────────────────────────────────────────────────
To review and annotate the review, open it in a browser:

    open file://{$ANNOT_HTML}

Click any line to add YOUR OWN note. The sidebar collects every note,
the "Copy Prompt" button gathers them into one structured prompt.
Paste that prompt back into this chat and Claude revises review.md
from your notes. Annotations persist in your browser if you close
the tab and reopen the same file.
────────────────────────────────────────────────────────────────────

You can also:
- Feed BLOCKER + MAJOR findings into a follow-up plan:
    /trekplan --brief {review_path}
- Re-run with `--quick` for a faster correctness-only pass
- Re-run with `--since <ref>` to narrow scope
```

Per **Handover 6**, BLOCKER and MAJOR findings are consumed by
`/trekplan --brief review.md` to produce a remediation plan. The
review's frontmatter `findings:` list and the trailing JSON block are
the contract for that handover (see `docs/HANDOVER-CONTRACTS.md`).

## Profile (v4.1)

Accepts `--profile <name>` where `<name>` is `economy`, `balanced`, `premium`,
or a custom profile under `voyage-profiles/`. Default: `premium`.

Resolution order (per `lib/profiles/resolver.mjs`):
1. `--profile` flag (source: `flag`)
2. `VOYAGE_PROFILE` env-var (source: `env`)
3. `premium` default (source: `default`)

The selected profile drives `phase_models.review` — `economy` uses sonnet
for the brief-conformance + code-correctness reviewers; `balanced` and
`premium` use opus (review benefits from deeper reasoning).

Examples:
```
/trekreview --profile balanced --project .claude/projects/2026-05-09-add-auth
VOYAGE_PROFILE=premium /trekreview --project ...
```

Stats records emit `profile` and `profile_source`.

## Composition rule (v5.1)

Independent of the profile system. When `brief.md` carries
`phase_signals` (brief_version ≥ 2.1), each downstream phase resolves
effort + model as:

```
effort_for_phase = brief.phase_signals[<phase>]?.effort ?? 'standard'
model_for_phase  = brief.phase_signals[<phase>]?.model  ?? profile.phase_models[<phase>]
```

The brief signal wins per-phase when present; the profile fills any
gaps. Composition is mechanically resolved via
`node ${CLAUDE_PLUGIN_ROOT}/lib/profiles/phase-signal-resolver.mjs`
invoked in Phase 2; the resolved JSON is captured as `phase_signal_result`
and passed to `Agent` tool calls explicitly. The resolver controls only
the orchestrator and the model parameter at Agent-spawn sites — sub-agents
otherwise read `model:` from their own `agents/*.md` frontmatter (still
pinned to `opus`).

For `/trekreview` specifically: `effort == 'low'` activates the existing
`--quick`-equivalent code-path (skip the brief-conformance reviewer; run
correctness-only). `effort == 'standard'` (or absent) → no change.
`effort == 'high'` activates the high-effort behavior documented under
`### High-effort behavior (v5.1.1)` below.

### Sequencing gate surface

Phase 1 already calls `brief-validator.mjs --soft` against `{brief_path}`.
If the validator returns `BRIEF_V51_MISSING_SIGNALS` in `errors`
(brief_version ≥ 2.1 without `phase_signals` or `phase_signals_partial:
true`), halt with: `Brief is brief_version 2.1 but does not carry
phase_signals — re-run /trekbrief to commit them (Phase 3.5).`
Enforcement is validator-only; this surface just makes the friendly hint
readable.

### High-effort behavior (v5.1.1)

When `phase_signal_result.effort == 'high'` for the `review` phase,
skip Pass 3 (Cloudflare reasonableness filter) in
`agents/review-coordinator.md`. Passes 1, 2, and 4 still run.
Rationale: high-effort review trusts the operator to weigh borderline
findings rather than have the coordinator drop them. To prevent
unknown `rule_key` values from polluting downstream remediation plans
(Handover 6), the coordinator applies its v5.1.1 high-effort
normalization rule — substituting unknown `rule_key` values with the
literal string `PLAN_EXECUTE_DRIFT` (the most general drift category
in the 12-entry catalogue) and preserving the original in
`original_rule_key`. See `agents/review-coordinator.md` § Pass 3
"High-effort normalization (v5.1.1)" for the full normalization spec.

Standard effort (or absent): run all 4 passes as usual.
Low effort: skip the brief-conformance reviewer entirely (existing
`--quick`-equivalent code-path).

## Hard rules

- **Brief is the contract.** Every finding in the review traces to a
  brief section via `brief_ref`, except `SCOPE_CREEP_BUILT` (which
  traces to "no anchor"). Conformance is the conformance reviewer's
  job — code-correctness findings carry generic anchors like
  `"NFR — code correctness"`.
- **Independent reviewers.** Do NOT cross-feed findings between
  brief-conformance-reviewer and code-correctness-reviewer. The
  coordinator is the only place where outputs combine.
- **Bounded coordination.** Synthesis-level inference across files is
  forbidden in v1.0. The coordinator dedups, filters, and computes the
  verdict — nothing more.
- **Triage map respected.** Files marked `skip` MUST appear in the
  Coverage section. Silent drops are `COVERAGE_SILENT_SKIP` (MAJOR).
- **Block-style YAML for findings list.** The frontmatter parser does
  not support flow-style arrays. `findings: [a, b]` is broken; use
  `findings:\n  - a\n  - b`.
- **Refuse-with-suggestion above 100 files / 100K tokens.** Never run
  blind on a giant diff. Use AskUserQuestion to surface the gate.
- **Cost.** Sub-agents use their pinned `model:` frontmatter (currently `opus`).
  When `phase_signals[<phase>].model` is set, the orchestrator AND Agent-spawn
  sites use the resolved model (`phase_signal_result.model`) for that phase.
  Frontmatter is the default; brief signal is the per-phase override.
- **Privacy.** Never log secrets, tokens, or credentials in review.md.
  Findings citing files with secret-like content must redact the secret
  in the `detail` field.
- **Honesty.** If the diff is trivially small or all-skip, say so. Do
  not pad findings to make the review look thorough.
- **No production code.** This command never runs production code, never
  writes to anything outside `{project_dir}` and `${CLAUDE_PLUGIN_DATA}`.
