bmad-review
bmad-code-org/bmad-method
Run multiple review lenses on code and documents to surface adversarial critique, edge cases, gaps, and structural issues.
What is bmad-review?
bmad-review applies a configurable set of review lenses—each with its own analytical stance—to diffs, pull requests, and artifacts. Use it only when explicitly asked to review; it reports findings triaged by lens and severity, never padding results.
- Runs multiple review lenses (adversarial critique, edge cases, verification gaps, structure, prose) on a single pass
- Reports findings in a canonical shape, grouped by lens and severity
- Respects lens-specific stances: adversarial lens requires concrete findings; editorial lenses critique organization and expression only
- Supports custom lenses and overrides via `customize.toml` in the project's `_bmad/` directory
- Stages diffs, branches, uncommitted changes, and documents as files for consistent analysis
- Handles both code and documentation content with appropriate lens selection
How to install bmad-review
npx skills add https://github.com/bmad-code-org/bmad-method --skill bmad-review- BMad setup in the project (a `_bmad/` directory with configuration)
- For full customization: `customize.toml` in `_bmad/` with `[workflow]` table defining lenses and review guidance
- Optional: `uv` and Python for resolving customization; fallback to shipped defaults if not available
How to use bmad-review
- 1.Install the skill: `npx skills add https://github.com/bmad-code-org/bmad-method --skill bmad-review`
- 2.Ask the agent to review a diff, pull request, or artifact—use the word 'review' explicitly
- 3.Optionally specify which lenses to run (e.g., 'review with adversarial and edge-case lenses only')
- 4.Optionally provide context via `also_consider` or `claims` (commit messages, change narrative)
- 5.Read the triaged findings report; overlap between lenses indicates stronger signal
Use cases
- Review a pull request for adversarial critique, edge cases, and structural issues before merge
- Audit a specification or requirements document for gaps, clarity, and internal consistency
- Examine a code diff for verification gaps and potential unhandled scenarios
- Critique prose quality and organization in technical documentation
- Run a focused review using only specific lenses (e.g., edge-case and adversarial only)
- Code reviewers and pull-request approvers
- Technical writers and documentation maintainers
- QA and verification engineers
- Architects reviewing design documents and specifications
- Development teams using BMad-based workflows
bmad-review FAQ
Only when you explicitly ask for a review of a diff, pull request, code file, or document. Do not invoke it uninvited or on edits the agent just made; a request to act on earlier feedback is a change, not a review.
The skill ships with several lenses (adversarial critique, edge cases, verification gaps, structure, prose) but the exact set is determined by `{workflow.lenses}` in your project's `customize.toml`. You can override or add lenses there.
Yes. Name the lenses you want in your request (e.g., 'review with adversarial and edge-case lenses') or use the directive form `skill:bmad-review lenses=<code>[,<code>...]`.
The skill will offer to run the `bmad` skill's setup, installing BMad first if needed. Alternatively, it falls back to shipped defaults and reads `customize.toml` directly.
The adversarial lens requires at least ten concrete findings; an empty result signals it should re-check. Other lenses treat an empty result as valid. Editorial lenses critique only organization and expression, not content itself.

name: bmad-review description: 'Runs one or more installed review lenses — adversarial critique, edge cases, verification gaps, structure, prose — and reports triaged findings. Use when, and only when, the user asks you to review a diff, a pull request, or an artifact — code or documents, one or many — and actually says "review"; an explicit skill:bmad-review directive from another skill counts as that ask. A request to act on feedback from an earlier review is a change, not a review. Never invoke this uninvited, including on edits you just made.'
BMad Review
Review content through lenses — each a distinct method and stance — and report findings in one canonical shape. Report what is real — never pad to look thorough. Each lens sets its own stance toward the content and toward zero findings: for most an empty result is valid; the adversarial lens requires at least ten concrete findings and treats an empty list as a signal to re-check; the editorial lenses hold content sacrosanct and critique only how it is organized and expressed.
The lens set is whatever {workflow.lenses} resolves to, not a fixed list — overrides add lenses and replace shipped ones. Never claim a capability from this file; read the resolved lenses and work from those.
Inputs
- content — what to review: a diff, branch, uncommitted changes, file, spec, story, or any document. Args:
[path]. - lenses (optional) — one or more lens codes or names, however the caller expresses them: a spoken request, or a directive of the form
skill:bmad-review lenses=<code>[,<code>...](the form bmm'sdoc_standardsuses). Default: every applicable lens (a full review). - also_consider (optional) — areas to keep in mind alongside each lens's normal analysis.
- claims (optional) — the change's own narrative: the commit messages it covers, or whatever description of it the caller supplied. Goes to the edge-case lens alone.
- pre-resolved customization (optional) —
[workflow]field values supplied by a forwarding caller. See Execution step 1.
Conventions
- Bare paths (e.g.
references/lens-edge-case-hunter.md) resolve from{skill-root}— this skill's installed directory, wherecustomize.tomllives.{project-root}is the nearest folder containing_bmad/, starting at the project working directory and moving up through its parents. {workflow.<name>}resolves to fields incustomize.toml's[workflow]table (overrides win per BMad merge rules).- In
style_guide,review_guidance, andpersistent_facts, a value prefixedfile:is a path or glob — load that file's contents. If afile:value cannot be read, name the failed file in the output header and continue: the shipped baseline forstyle_guide, the remaining entries otherwise.
Execution

Resolve customization:
uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --project-root {project-root} --key workflow.- Script not found: BMad is not set up here. Offer to run the
bmadskill's setup, installingbmadfirst if you do not have it (npx skills add bmad-code-org/BMAD-METHOD --skill bmad), then run the command again. - Any other failure: read

Forwarded activation: if a caller invoked you with pre-resolved customization fields (e.g. the
bmad-editorial-reviewshim), honor them verbatim for those named fields — they already carry the user's overrides — and resolve only the remaining fields from your owncustomize.toml. Then execute each{workflow.activation_steps_prepend}entry in order, hold{workflow.persistent_facts}as standing context for the session, and treat{workflow.review_guidance}entries as standing review directives for every lens. - Script not found: BMad is not set up here.

Load the content. Stage it once as a file: when the content is a branch, uncommitted work, or a commit range, use the repository's version-control tooling to write the unified diff to a uniquely-named file in the system temp directory and take that file's absolute path as the content. A branch means its diff against the merge base with its base branch; uncommitted work includes untracked files. Stage
claimsto its own file the same way — it is input for one lens, staged separately precisely so the other lenses never see it. If the content is empty or cannot be decoded as text: when the caller expects the raw findings JSON array (e.g. the legacy edge-case forwarder), return[{"location":"N/A","trigger_condition":"Input empty or undecodable","guard_snippet":"Provide valid content to review","potential_consequence":"Review skipped — no analysis performed"}](nolensfield) and stop; otherwise say what's wrong and ask for reviewable content. Classify the content — diff, source file, function, or document — and whether it is code or docs; scope rules and lens applicability both depend on it. A document that defines behavior (spec, requirements, plan, story) isdocsthat a behavioral lens may still apply to; judge bywhen. -
Select lenses from
{workflow.lenses}. A lens with an emptyinstructionis disabled. If the user or caller named lenses, run exactly those only —applies_toandwhendo not filter an explicit request. Otherwise run every enabled lens whoseapplies_tocovers the content class (anyalways covers) and whosewhenapplies. -
Announce the plan in one line before running anything: the content class, the lenses about to run, and — when any lens has
afterset — that it runs on top of the named lens's findings. Skip the announcement entirely when the caller pinned an exact output contract (the legacy forwarders that demand raw JSON or one exact line) — their contract covers everything you emit, not just the findings block. Then execute each{workflow.activation_steps_append}entry in order. -
Run the independent lenses — every selected lens without
after. Each sees the content andalso_consider, never another lens's findings. Follow each lens'sinstruction; the shipped lenses load their reference file just-in-time, so load only what runs. When subagents are available, launch every independent lens before handling any lens's result. Try running them simultaneously: spawn one per lens; give it the lensinstructionwith{skill-root}and paths resolved absolute, the absolute path of the staged content file (a lens prompt carries the path and the lens reads the file, never the content bytes; inline the content only when it was never staged as a file), anyalso_considerareas, the standing review directives, theclaimspath to the edge-case lens alone (marked to leave unread until its instructions call for it), and the constraint "Return ONLY your findings — no other output. Do not invoke any skill, and do not spawn subagents of your own — you are the reviewer. Return your findings as text in your final message; do not route them through any findings-reporting tool the host may offer." Otherwise run the lenses sequentially yourself, completing one before starting the next. -
Run the dependent lenses — every selected lens with
after, once the lens it names has completed, passing that lens's findings in. A lens whoseaftertarget was not selected or produced nothing still runs, with no prior findings. Dependent lenses that name different targets are independent of each other: launch every ready one before handling any of their results. Try running them simultaneously. When subagents are available, spawn them with the same constraint as independent lenses: "Return ONLY your findings — no other output. Do not invoke any skill, and do not spawn subagents of your own — you are the reviewer. Return your findings as text in your final message; do not route them through any findings-reporting tool the host may offer." -
Assemble and present per Output below. Keep every lens's findings — overlap between lenses is signal, not duplication; note it in the markdown report rather than deduping. Execute
{workflow.on_complete}if set.
Output
One JSON array holding every finding from every lens. Each finding carries:
lens— the code of the lens that produced itlocation— where in the content (file:line-range for code, section for documents)trigger_condition— the problem, or the condition that exposes it, in one lineguard_snippet— the concrete fix, guard, or missing checkpotential_consequence— what goes wrong if it ships as-is
Each lens file refines these semantics for its findings and may add lens-specific fields (e.g. kind/confidence on deletion findings, gap_shape/consumer/evidence on verification-gap findings). A lens file may instead declare its own findings shape and rendering — the editorial lenses render a findings table — and that shape wins for that lens's findings. [] is valid when nothing is found. No severity, priority, or ranking anywhere.
Present per {workflow.output_format} — "json" (the raw array in a fenced json block), "markdown", or "both" — unless the caller requested a specific shape; a legacy forwarder's output contract always wins, and governs everything you emit rather than the findings block alone. The markdown report groups findings by lens, each rendered in its declared shape: a short block per finding rendering the fields plus any extras worth surfacing, one line for a lens that found nothing, and a plain clean statement when the whole review is clean. Shape the report per {workflow.output_preferences}.
When {workflow.report_path} is set, write the report there; otherwise present it in chat.
