Resumen

Review AI-generated or human-written code changes with fallow's graph-grounded review brief. Subtracts deterministic concerns (unused code, complexity, duplication, styling) from the loop, ranks what to look at by blast radius and risk, and surfaces the few consequential structural decisions (new public-API contracts, coupling/boundary crossings, new dependencies) as framed judgment questions anchored to verifiable signals. Drives a closed agent-contract loop: fetch the walkthrough guide, return a judgment, and have fallow post-validate it against the live graph (hallucinated or stale judgments are rejected). Use when asked to review a PR, review a branch, review a diff, do a code review, or check changed code before merge.

Fallow Review: graph-grounded code review

fallow review turns a changeset into a deterministic, graph-derived review brief and an agent-contract loop. It answers "where do I look, and what calls actually need human taste?" rather than "will CI block this?" (that is fallow audit, which gates). review always exits 0, so it is safe to run regardless of verdict.

The four jobs it does, in order:

  • subtract: dead code, complexity, duplication, and styling for the changed files are reported and kept OUT of the judgment loop, so attention is not spent on what a deterministic check already owns.
  • focus: changed-file units are ranked by a composite attention score (fan-in/out, risk zone, change shape) with a review-here / not-prioritized label and a full deprioritized escape-hatch list, so nothing is hidden.
  • structure: the decision surface lifts the handful of consequential STRUCTURAL decisions out of the diff and frames each as a judgment question, capped to a working-memory-sized set, each anchored to a signal_id fallow emitted.
  • direct: the walkthrough guide hands an agent a graph-derived digest, the review direction, a graph-snapshot pin, and the exact judgment schema to return.

When to use

  • Reviewing a PR, branch, or diff (AI-generated or human-written) before merge.
  • After an agent has done work and removed the fallow findings it could; this surfaces what is left for human/agent taste.
  • Producing inline-reviewable judgments that can flow back to the agent that wrote the code.

When NOT to use

  • Gating CI on a pass/fail verdict: use fallow audit (it exits non-zero on a fail verdict).
  • Whole-project health, cleanup, or dead-code reports: use the fallow skill.

Quick human brief

# Auto-detect the base (merge-base against the upstream / remote default):
fallow review

# Pin the base, or scope to a precise diff:
fallow review --base origin/main
git diff --find-renames origin/main...HEAD | fallow review --base origin/main --diff-stdin

The human brief prints the orientation facts, the focus map, and the decision surface ("Decisions to make"). --format json emits the full structured envelope (decisions, focus, deltas, impact_closure, partition, graph_facts). --max-decisions N tunes the cap (clamped to a small band). --show-deprioritized expands what the focus map collapsed.

The decision surface

Each decision is a framed question anchored to a signal_id fallow deterministically derived from the graph (a delta key or a coordination-gap key). There are exactly three shippable categories:

  • coupling-boundary: a new cross-zone dependency edge.
  • public-api-contract: a new exported public-API surface, or a changed contract consumed by modules OUTSIDE this diff (a coordinate-or-confirm signal).
  • dependency: a changed package.json that adds third-party entries or moves a declared entry across a major version (or a 0.x minor). One batched decision per manifest per kind, weighted by the graph's in-repo importers of the affected packages: blast is the importer count, internal_consumer_count the importers outside the diff. Both counts are a union over the batched packages. An entry outside dependencies shows a (dev), (optional), or (peer) tag in the question. digest.deltas carries the keys as dependency_added (<manifest>::<name>) and dependency_major_bumped (<manifest>::<name>@<from>-><to>); both lists are always present, possibly empty. Minor and patch bumps and non-numeric ranges (workspace, file, git, tags) are never candidates. A dependency decision has no suppress action: it anchors on package.json, which cannot carry a comment, so never paste a // fallow-ignore line into a manifest. The decision_surface MCP tool surfaces the same dependency decisions as the CLI. Framing rule: cite the changelog question ("which documented change in <from> to <to> reaches these N importers?"); do not guess the behavior change.

A decision may carry previous_signal_id when its anchor file was renamed in the change: that is the signal_id the same decision would have had at the old path, so a review surface can re-attach a prior reviewer comment across a git mv.

Eliciting the broader trade-offs (taste ownership)

The decision surface above is the DETERMINISTIC slice: only the trade-offs fallow can prove from the graph (the three categories). Real architectural trade-offs are broader (abstraction level, error-handling strategy, data-model shape, eager-vs-lazy, state ownership, extensibility-vs-YAGNI, testability, trust boundaries), and none of those are graph-detectable. Surfacing them needs a model reading the diff, not a static pass.

Run the trade-off elicitation prompt in references/tradeoff-elicitation.md over the diff plus the guide. It applies TASTE OWNERSHIP: the model makes each choice legible and frames a genuinely open question; the human decides. The prompt carries the honesty contract (diff anchoring, the observed / tradeoff / question split, deterministic: false fencing, provenance, the top-five cap with honest abstention, no duplication of the deterministic surface, options that never pick). fallow owns what it can prove, the prompt covers the rest, and the fencing keeps the two from being confused.

Running it as a review step

When a review surface (the fallow review app, or you in the terminal) wants the trade-off surface alongside the deterministic decisions:

  1. Fetch the guide and read the diff: 
    fallow review --base <ref> --walkthrough-guide --format json > guide.json
git diff <ref>...HEAD            # or: git diff --cached  for staged work
  2. Run the references/tradeoff-elicitation.md prompt over the diff plus guide.json.
  3. Emit the envelope (the { graph_snapshot_hash, abstained, tradeoffs[] } shape) to .fallow-review/tradeoffs.json in the repo root, the sibling of .fallow-review/feed.jsonl, so a review surface can render it.

This step is deliberately NOT part of the post-validate agent-contract loop below. The trade-off envelope is never round-tripped through fallow review --walkthrough-file (which only validates emitted signal_ids), so it carries NO fallow-grade guarantee: every item stays deterministic: false, agent-self-checked against the diff, not graph-validated. Do not present it as fallow-validated.

The agent-contract loop

The loop lets an agent produce judgments that fallow post-validates against the live graph. The verifier is the graph, not a second model.

  1. Fetch the guide:

    fallow review --base origin/main --walkthrough-guide --format json > guide.json

    The guide contains: digest (the brief + decision surface), direction (where to look), graph_snapshot_hash (the staleness pin), agent_schema (the exact shape to return), and injection_note. The digest is built from the graph ONLY; PR prose is never folded in, so the guide is injection-resistant by construction.

  2. Read the decisions in digest. Each carries a signal_id, a category, the framed question, and an anchor_file / anchor_line.

  3. Return a judgment matching agent_schema:

    {
  "graph_snapshot_hash": "<echo the value from the guide>",
  "judgments": [
    {
      "signal_id": "<one signal_id fallow emitted>",
      "framing": "<your reasoning for the human reviewer>",
      "action": "<block | address | consider | fyi>",
      "concern": "<optional: one lens from agent_schema.concern_vocabulary>"
    }
  ]
}

    Every signal_id MUST be one fallow emitted in the guide (emitted_signal_ids). An unanchored id is rejected. Echo the graph_snapshot_hash verbatim.

    action tells the author what the judgment asks of them: block and address are required actions, consider is optional, fyi needs nothing. concern names the lens; prefer the guide's agent_schema.concern_vocabulary, thirteen kebab-case lenses: abstraction, coupling, data-model, error-handling, control-flow, performance, dependencies, api-ergonomics, compatibility, state-ownership, extensibility, testability, trust-boundary. The guide publishes both lists as agent_schema.action_vocabulary and agent_schema.concern_vocabulary; read them from the guide rather than from this file. action_vocabulary is enforced; concern_vocabulary is advisory, any string is accepted.

  4. Post-validate:

    fallow review --base origin/main --walkthrough-file judgment.json --format json

    The response sorts each judgment into:

    • accepted: the signal_id was emitted and the snapshot matches; the agent's framing is fenced as non-deterministic (deterministic: false) and never gates. The action is echoed next to agent_framing, fenced the same way: it is an instruction to the author, never a fallow fact.
    • rejected with reason: "unanchored-signal-id": the signal_id was never emitted (a hallucination). Drop or correct it.
    • rejected with reason: "invalid-action" and invalid_value (the label fallow refused): the action is outside the vocabulary. This is reported only after the anchor resolved; a hallucinated anchor plus a bad label rejects as unanchored-signal-id / unknown-change-anchor instead. Fix the anchor first, then the label.
    • rejected with reason: "stale-snapshot" and stale: true: the tree moved since the guide was fetched. Re-fetch the guide and redo the judgments.

Compose the review

Validation is not the review. Once the judgments are accepted, render them for a human in this fixed order, so the reader lands on what changes the outcome first and the deterministic remainder last:

  1. Accepted decision judgments, in direction.order. Each one carries the digest question and tradeoff verbatim, then your framing, then the number that gives it weight: internal_consumer_count, the out_of_diff paths, or the unit's scoring_budget.
  2. Trade-offs from the elicitation step, ranked by consequence, at most five. When the envelope is abstained: true, print one line saying so; do not fill the slot.
  3. Subtract as ONE line with the counts from the brief: "handled deterministically: N dead-code, N duplication, N complexity, N styling; not in the discussion". Never re-derive any of these from the diff; the brief already owns them.
  4. Deprioritized as one line with the count and --show-deprioritized as the escape hatch, so nothing is hidden and nothing is padded.
  5. A review with zero decisions and an abstained trade-off envelope is a complete review: "nothing consequential; deterministic findings: N". It is not a failure and never a reason to invent items.

Two graph facts feed the composition without adding items:

  • Each direction unit carries test_adjacency: none (no test file imports this unit), untouched (a test importer exists but is not in the diff), or changed (a test importer is in the diff). It is absent for test files and when the graph was not retained. For a review-here unit with none, as

# Fallow Review: graph-grounded code review

`fallow review` turns a changeset into a deterministic, graph-derived review brief and an agent-contract loop. It answers "where do I look, and what calls actually need human taste?" rather than "will CI block this?" (that is `fallow audit`, which gates). `review` always exits 0, so it is safe to run regardless of verdict.

The four jobs it does, in order:

- **subtract**: dead code, complexity, duplication, and styling for the changed files are reported and kept OUT of the judgment loop, so attention is not spent on what a deterministic check already owns.
- **focus**: changed-file units are ranked by a composite attention score (fan-in/out, risk zone, change shape) with a `review-here` / `not-prioritized` label and a full `deprioritized` escape-hatch list, so nothing is hidden.
- **structure**: the decision surface lifts the handful of consequential STRUCTURAL decisions out of the diff and frames each as a judgment question, capped to a working-memory-sized set, each anchored to a `signal_id` fallow emitted.
- **direct**: the walkthrough guide hands an agent a graph-derived digest, the review direction, a graph-snapshot pin, and the exact judgment schema to return.

## When to use

- Reviewing a PR, branch, or diff (AI-generated or human-written) before merge.
- After an agent has done work and removed the fallow findings it could; this surfaces what is left for human/agent taste.
- Producing inline-reviewable judgments that can flow back to the agent that wrote the code.

## When NOT to use

- Gating CI on a pass/fail verdict: use `fallow audit` (it exits non-zero on a fail verdict).
- Whole-project health, cleanup, or dead-code reports: use the `fallow` skill.

## Quick human brief

```bash

fallow review

# Pin the base, or scope to a precise diff:
fallow review --base origin/main
git diff --find-renames origin/main...HEAD | fallow review --base origin/main --diff-stdin
```

The human brief prints the orientation facts, the focus map, and the decision surface ("Decisions to make"). `--format json` emits the full structured envelope (`decisions`, `focus`, `deltas`, `impact_closure`, `partition`, `graph_facts`). `--max-decisions N` tunes the cap (clamped to a small band). `--show-deprioritized` expands what the focus map collapsed.

## The decision surface

Each decision is a framed question anchored to a `signal_id` fallow deterministically derived from the graph (a delta key or a coordination-gap key). There are exactly three shippable categories:

- **coupling-boundary**: a new cross-zone dependency edge.
- **public-api-contract**: a new exported public-API surface, or a changed contract consumed by modules OUTSIDE this diff (a coordinate-or-confirm signal).
- **dependency**: a changed `package.json` that adds third-party entries or moves a declared entry across a major version (or a `0.x` minor). One batched decision per manifest per kind, weighted by the graph's in-repo importers of the affected packages: `blast` is the importer count, `internal_consumer_count` the importers outside the diff. Both counts are a union over the batched packages. An entry outside `dependencies` shows a `(dev)`, `(optional)`, or `(peer)` tag in the question. `digest.deltas` carries the keys as `dependency_added` (`<manifest>::<name>`) and `dependency_major_bumped` (`<manifest>::<name>@<from>-><to>`); both lists are always present, possibly empty. Minor and patch bumps and non-numeric ranges (workspace, file, git, tags) are never candidates. A `dependency` decision has no `suppress` action: it anchors on `package.json`, which cannot carry a comment, so never paste a `// fallow-ignore` line into a manifest. The `decision_surface` MCP tool surfaces the same dependency decisions as the CLI. Framing rule: cite the changelog question ("which documented change in `<from>` to `<to>` reaches these N importers?"); do not guess the behavior change.

A decision may carry `previous_signal_id` when its anchor file was renamed in the change: that is the `signal_id` the same decision would have had at the old path, so a review surface can re-attach a prior reviewer comment across a `git mv`.

## Eliciting the broader trade-offs (taste ownership)

The decision surface above is the DETERMINISTIC slice: only the trade-offs fallow can prove from the graph (the three categories). Real architectural trade-offs are broader (abstraction level, error-handling strategy, data-model shape, eager-vs-lazy, state ownership, extensibility-vs-YAGNI, testability, trust boundaries), and none of those are graph-detectable. Surfacing them needs a model reading the diff, not a static pass.

Run the trade-off elicitation prompt in `references/tradeoff-elicitation.md` over the diff plus the guide. It applies TASTE OWNERSHIP: the model makes each choice legible and frames a genuinely open question; the human decides. The prompt carries the honesty contract (diff anchoring, the `observed` / `tradeoff` / `question` split, `deterministic: false` fencing, provenance, the top-five cap with honest abstention, no duplication of the deterministic surface, `options` that never pick). fallow owns what it can prove, the prompt covers the rest, and the fencing keeps the two from being confused.

### Running it as a review step

When a review surface (the fallow review app, or you in the terminal) wants the trade-off surface alongside the deterministic decisions:

1. Fetch the guide and read the diff:
   ```bash
   fallow review --base <ref> --walkthrough-guide --format json > guide.json
   git diff <ref>...HEAD            # or: git diff --cached  for staged work
   ```
2. Run the `references/tradeoff-elicitation.md` prompt over the diff plus `guide.json`.
3. Emit the envelope (the `{ graph_snapshot_hash, abstained, tradeoffs[] }` shape) to `.fallow-review/tradeoffs.json` in the repo root, the sibling of `.fallow-review/feed.jsonl`, so a review surface can render it.

This step is deliberately NOT part of the post-validate agent-contract loop below. The trade-off envelope is never round-tripped through `fallow review --walkthrough-file` (which only validates emitted `signal_id`s), so it carries NO fallow-grade guarantee: every item stays `deterministic: false`, agent-self-checked against the diff, not graph-validated. Do not present it as fallow-validated.

## The agent-contract loop

The loop lets an agent produce judgments that fallow post-validates against the live graph. The verifier is the graph, not a second model.

1. **Fetch the guide:**

   ```bash
   fallow review --base origin/main --walkthrough-guide --format json > guide.json
   ```

   The guide contains: `digest` (the brief + decision surface), `direction` (where to look), `graph_snapshot_hash` (the staleness pin), `agent_schema` (the exact shape to return), and `injection_note`. The digest is built from the graph ONLY; PR prose is never folded in, so the guide is injection-resistant by construction.

2. **Read the decisions** in `digest`. Each carries a `signal_id`, a `category`, the framed `question`, and an `anchor_file` / `anchor_line`.

3. **Return a judgment** matching `agent_schema`:

   ```json
   {
     "graph_snapshot_hash": "<echo the value from the guide>",
     "judgments": [
       {
         "signal_id": "<one signal_id fallow emitted>",
         "framing": "<your reasoning for the human reviewer>",
         "action": "<block | address | consider | fyi>",
         "concern": "<optional: one lens from agent_schema.concern_vocabulary>"
       }
     ]
   }
   ```

   Every `signal_id` MUST be one fallow emitted in the guide (`emitted_signal_ids`). An unanchored id is rejected. Echo the `graph_snapshot_hash` verbatim.

   `action` tells the author what the judgment asks of them: `block` and `address` are required actions, `consider` is optional, `fyi` needs nothing. `concern` names the lens; prefer the guide's `agent_schema.concern_vocabulary`, thirteen kebab-case lenses: `abstraction`, `coupling`, `data-model`, `error-handling`, `control-flow`, `performance`, `dependencies`, `api-ergonomics`, `compatibility`, `state-ownership`, `extensibility`, `testability`, `trust-boundary`. The guide publishes both lists as `agent_schema.action_vocabulary` and `agent_schema.concern_vocabulary`; read them from the guide rather than from this file. `action_vocabulary` is enforced; `concern_vocabulary` is advisory, any string is accepted.

4. **Post-validate:**

   ```bash
   fallow review --base origin/main --walkthrough-file judgment.json --format json
   ```

   The response sorts each judgment into:
   - `accepted`: the `signal_id` was emitted and the snapshot matches; the agent's `framing` is fenced as non-deterministic (`deterministic: false`) and never gates. The `action` is echoed next to `agent_framing`, fenced the same way: it is an instruction to the author, never a fallow fact.
   - `rejected` with `reason: "unanchored-signal-id"`: the `signal_id` was never emitted (a hallucination). Drop or correct it.
   - `rejected` with `reason: "invalid-action"` and `invalid_value` (the label fallow refused): the `action` is outside the vocabulary. This is reported only after the anchor resolved; a hallucinated anchor plus a bad label rejects as `unanchored-signal-id` / `unknown-change-anchor` instead. Fix the anchor first, then the label.
   - `rejected` with `reason: "stale-snapshot"` and `stale: true`: the tree moved since the guide was fetched. Re-fetch the guide and redo the judgments.

## Compose the review

Validation is not the review. Once the judgments are accepted, render them for a human in this fixed order, so the reader lands on what changes the outcome first and the deterministic remainder last:

1. **Accepted decision judgments**, in `direction.order`. Each one carries the digest `question` and `tradeoff` verbatim, then your `framing`, then the number that gives it weight: `internal_consumer_count`, the `out_of_diff` paths, or the unit's `scoring_budget`.
2. **Trade-offs** from the elicitation step, ranked by `consequence`, at most five. When the envelope is `abstained: true`, print one line saying so; do not fill the slot.
3. **Subtract** as ONE line with the counts from the brief: "handled deterministically: N dead-code, N duplication, N complexity, N styling; not in the discussion". Never re-derive any of these from the diff; the brief already owns them.
4. **Deprioritized** as one line with the count and `--show-deprioritized` as the escape hatch, so nothing is hidden and nothing is padded.
5. A review with zero decisions and an abstained trade-off envelope is a complete review: "nothing consequential; deterministic findings: N". It is not a failure and never a reason to invent items.

Two graph facts feed the composition without adding items:

- Each direction unit carries `test_adjacency`: `none` (no test file imports this unit), `untouched` (a test importer exists but is not in the diff), or `changed` (a test importer is in the diff). It is absent for test files and when the graph was not retained. For a `review-here` unit with `none`, as
