mcp-server-trello: Skill for Claude Code

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 treats it as suspicious; 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's doc_standards uses). Default: every applicable lens (a full review).
• also_consider (optional) — areas to keep in mind alongside each lens's normal analysis.
• 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, where customize.toml lives. {project-root} resolves to the project working directory.
• {workflow.<name>} resolves to fields in customize.toml's [workflow] table (overrides win per BMad merge rules).
• In style_guide, review_guidance, and persistent_facts, a value prefixed file: is a path or glob — load that file's contents. If a file: value cannot be read, name the failed file in the output header and continue: the shipped baseline for style_guide, the remaining entries otherwise.

Execution

1. Resolve customization: uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow. On failure, read {skill-root}/customize.toml directly and use defaults. Forwarded activation: if a caller invoked you with pre-resolved customization fields (e.g. the bmad-editorial-review shim), honor them verbatim for those named fields — they already carry the user's overrides — and resolve only the remaining fields from your own customize.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.
2. Load the content. If it 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"}] (no lens field) 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) is docs that a behavioral lens may still apply to; judge by when.
3. Select lenses from {workflow.lenses}. A lens with an empty instruction is disabled. If the user or caller named lenses, run exactly those only — applies_to and when do not filter an explicit request. Otherwise run every enabled lens whose applies_to covers the content class (any always covers) and whose when applies.
4. Announce the plan in one line before running anything: the content class, the lenses about to run, and — when any lens has after set — 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.
5. Run the independent lenses — every selected lens without after. Each sees the content and also_consider, never another lens's findings. Follow each lens's instruction; the shipped lenses load their reference file just-in-time, so load only what runs. When subagents are available, spawn one per lens in parallel: give it the lens instruction with {skill-root} and paths resolved absolute, the content or where to read it, any also_consider areas, the standing review directives, and the constraint "Return ONLY your findings — no other output." Otherwise run the lenses sequentially yourself, completing one before starting the next.
6. Run the dependent lenses — every selected lens with after, once the lens it names has completed, passing that lens's findings in. A lens whose after target was not selected or produced nothing still runs, with no prior findings. Dependent lenses that name different targets are independent of each other and may run in parallel.
7. 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.
