@decantr/cli

Support status: core-supported
Release channel: stable

Decantr’s main local operator surface for scaffolding, auditing, inspecting, and maintaining Decantr projects.

Install

npm install -D @decantr/cli

Or run it without installing:

npx @decantr/cli scan
npx @decantr/cli new my-app --blueprint=esports-hq

Use decantr setup when you are unsure which path applies. It detects whether the repo is empty, already attached, or a Brownfield app and recommends the right entry path. Use decantr scan when you want a zero-commit Brownfield preview. It reads local files, detects framework/routes/styling/static-hosting/assistant-rule signals, previews typed Contract graph readiness in memory when a Decantr contract already exists, reports the contract capsule source-handle count and limit, prints a terminal report, and writes no .decantr files or report artifacts. Add --json when automation needs the ScanReportV1 payload. Use decantr new for a greenfield workspace in a fresh directory. With a starter-kit blueprint or archetype it uses the runnable adapter and Decantr CSS; without certified vocabulary content it creates a contract-only workspace unless you explicitly pass --adoption=decantr-css. Use decantr adopt when you already have an app and want Decantr governance without adopting a blueprint. Brownfield attach is proposal-driven: Decantr inventories the app, writes an observed essence proposal, hydrates hosted execution packs when online, and only applies the contract when you explicitly accept or merge it. Use decantr studio after adoption when you want a local Control Room for routes, findings, evidence, authority, and next actions. Use decantr doctor when the next step is unclear, decantr task <route> "<intent>" before asking an LLM to modify a route, decantr verify after the edit, decantr resolve when source and contract disagree, and decantr ci in required automation. If runtime source and Decantr context disagree, report the drift instead of guessing; in Brownfield the existing source is observed truth, accepted local law/style bridge is project authority where present, Essence V4 is the structural contract, and hosted packs stay advisory until mapped into local law. Use decantr graph when you want the Decantr 3 typed Contract graph, typed graph diff summary, manifest, content-addressed snapshot history, and cache-friendly contract capsule written under .decantr/graph; the capsule includes a bounded SourceArtifact path index so agents can discover valid file-impact handles without reading the full snapshot, and --capsule-source-limit <count> can tune that index for large repos. Add --route /feed --task "improve loading" --json when you want the exact task-ranked route-scoped subgraph an agent should inspect before editing, --node cmp:button --impact --json when you need the graph-shaped blast radius for a component, token, rule, finding, or source artifact, or --file src/app/page.tsx --impact --json when the agent knows the source file it is about to change. Route and impact ranking use deterministic weighted traversal plus local personalized PageRank and task boosts. Use --snapshot-id <id> to inspect a replayable history snapshot and --compare-to <id> --include-diff-ops --json to compare the selected/current graph against a prior snapshot. Use decantr codify --from-audit --style-bridge when you want project-owned UI patterns, optional behavior_obligations, local rules, and token/class bridge mappings such as button/card/shell/theme standards to appear in future task context and verification. Once accepted, that local law is the first Hybrid lane: the app still owns source and styling, but Decantr treats accepted local patterns, behavior obligations, rules, and style bridge mappings as project authority. In monorepos, app-scoped commands accept --project <app-path>. setup shows attach guidance before adoption and the day-two loop after adoption. Candidate discovery ranks product UI apps ahead of docs, Storybook, API, MCP helper, workbench, and package surfaces; decantr workspace list --json includes rank, category, score, and reason metadata so automation can explain why apps/web, apps/remix, or apps/dashboard was suggested first. Hosted pack hydration also follows the essence path: decantr registry compile-packs apps/web/decantr.essence.json --write-context writes into apps/web/.decantr/context. In contract-only/offline Brownfield, deferred hosted packs are optional context unless a present manifest references missing files. Use decantr init, decantr analyze, decantr check, and decantr health as advanced primitives when you need direct control over one step.

App-scoped primitives now share the same --project posture as the primary workflow commands. From a workspace root, health, status, upgrade, add, remove, theme, export, suggest, magic, rules, and telemetry target the selected app instead of the root. Task/read paths, local-law summaries, and refresh change summaries are printed as openable workspace paths. Nonexistent project paths fail immediately, and Brownfield adoption refuses component packages unless you intentionally pass --force-package.

Current starter adapter availability:

• react-vite is the React + Vite runnable bootstrap adapter
• next-app is the runnable Next.js App Router adapter
• vanilla-vite is the plain HTML/CSS/JS runnable bootstrap adapter
• vue-vite is the Vue 3 + Vite runnable bootstrap adapter
• sveltekit is the SvelteKit runnable bootstrap adapter
• angular is the Angular standalone runnable bootstrap adapter
• solid-vite is the Solid + Vite runnable bootstrap adapter
• other contract targets use the generic-web contract-only adapter until their runnable adapters land

decantr init --existing --adoption=decantr-css
decantr init --project=apps/web --yes
decantr init --assistant-bridge=preview
decantr rules preview
decantr rules apply

Adoption modes:

• contract-only writes Decantr essence/context/governance files without Decantr CSS files or @decantr/css dependency guidance.
• style-bridge writes bridge tokens/files that map Decantr intent onto an existing style system without requiring @decantr/css.
• decantr-css writes the full Decantr CSS files and runtime guidance.

Monorepos store both workspaceRoot and appRoot. Install Decantr at the workspace root if that is where dependencies are managed, but attach Decantr to an app root with --project=<path>.

pnpm add -D -w @decantr/cli
pnpm exec decantr setup
pnpm exec decantr workspace list
pnpm exec decantr adopt --project apps/web --yes
pnpm exec decantr doctor --project apps/web
pnpm exec decantr codify --from-audit --style-bridge --project apps/web
pnpm exec decantr codify --map-pattern hero --project apps/web
pnpm exec decantr ci init --project apps/web

Assistant rule integration is preview-first: --assistant-bridge=preview writes .decantr/context/assistant-bridge.md, decantr rules preview prints the bridge, and --assistant-bridge=apply or decantr rules apply mutates supported rule files with idempotent marked blocks. When .decantr/graph/contract-capsule.json exists, decantr task includes it in the read list and JSON payload so CLI-only agents can load the typed Contract capsule and its SourceArtifact path index before route-specific edits. When .decantr/graph/graph.snapshot.json exists, decantr task --json also includes graph.routeContext: the route node, scoped page/shell/pattern/component/token nodes, local law/style bridge nodes, behavior-obligation LocalRule nodes, open findings/evidence IDs, deterministic ranked nodes boosted by the task text, and the supporting edges. Accepted .decantr/local-patterns.json behavior_obligations also appear in localLaw.patterns[].behaviorObligations and localLaw.behaviorObligations so agents see project-owned dialog/form obligations before editing. If git changed files resolve to SourceArtifact nodes, decantr task --json also includes graph.changedFileContext so an agent can see source-file blast radius before editing or repairing the current diff.

decantr scan is different from the mutating Brownfield primitives: it is look-don't-touch reconnaissance for fit, route/style evidence, GitHub Pages hints, typed Contract graph readiness, capsule source-handle bounds, and next-command guidance. For attached Essence V4 apps it derives the graph preview in memory, reports stale/missing .decantr/graph artifacts, and still writes nothing. decantr analyze writes .decantr/doctrine-map.json, a ranked source-precedence map across security/data, architecture, design-system, workflow/CI, feature/business, assistant-specific, stale, and unsafe-to-cite evidence. It also writes .decantr/brownfield-intelligence.json, .decantr/theme-inventory.json, and .decantr/enrichment-backlog.md. The proposal groups routes into observed semantic domains such as auth, RBAC, billing, reporting, facilities, settings, and public surfaces across Next App/Pages Router, React Router, Angular Router, SvelteKit, Vue Router, and Nuxt file routes. Existing styling systems such as Tailwind, Bootstrap, MUI, Chakra, plain CSS, and Decantr CSS are observed as evidence instead of replaced. Theme variants are observed in the theme inventory without changing Essence V4. decantr adopt writes the first typed Contract graph baseline before verification so Project Health, task context, and agents can anchor to graph artifacts immediately. decantr codify --from-audit proposes .decantr/local-patterns.proposal.json and .decantr/rules.proposal.json with Hybrid authority guidance, source-derived button/card/form/theme evidence, variant hints, confidence tiers, and optional behavior_obligations for form controls and destructive confirmation dialogs when source evidence is strong; decantr codify --style-bridge proposes .decantr/style-bridge.proposal.json, mapping Decantr intent to project-owned tokens/classes without requiring @decantr/css; decantr codify --map-pattern <slug> maps a hosted or bundled registry pattern into an advisory local-law proposal without changing source. After review, decantr codify --accept promotes whichever proposals exist. decantr doctor reports whether the app is contract-only, Hybrid local law, style bridge, Decantr CSS, or Hybrid composition. decantr task prints that authority block and warns before mixing runtimes or adding Decantr CSS to a non-Decantr-CSS app. decantr suggest --from-code surfaces accepted local patterns and style bridge mappings from the app root or selected --project, and decantr ci prints accepted local-rule findings, behavior-obligation findings, plus style bridge status in text, markdown, and JSON reports. decantr verify --brownfield --local-patterns uses the Brownfield guard layer plus accepted local law to flag actionable missing doctrine coverage, unsafe context, missing assistant bridges, behavior-obligation drift, style drift, raw local-rule violations, and unsafe defaults without treating current database migrations as stale docs.

What It Does

• scaffolds Decantr projects from blueprints, archetypes, or prompts
• previews existing apps with read-only Brownfield scan reports
• guides users through human workflow commands: setup, adopt, doctor, task, verify, ci, and codify
• supports explicit workflow lanes: greenfield blueprint, greenfield contract-only, brownfield adoption, Hybrid local law, Hybrid style bridge, Hybrid Decantr CSS, and hybrid composition
• ranks monorepo app candidates with explainable metadata so product UI apps come before docs, Storybook, API, helper packages, and workbench surfaces
• generates execution-pack context files for AI coding assistants
• generates typed Contract graph artifacts, replayable snapshot history, graph diffs, manifests, source-file impact context, style-bridge Token nodes, behavior-obligation LocalRule nodes, and contract-capsule.json for agent sessions
• audits projects against Decantr contracts
• produces local Project Health reports, Evidence Bundles, workspace health, and a localhost Studio dashboard for end-user drift triage
• audits local vocabulary repositories with Content Health reports for schema, reference, and quality coverage
• searches the registry and showcase benchmark corpus
• runs real-world corpus harnesses with timing percentiles, slow-command budgets, root-smoke/app-scoped classification, and stable failure categories
• filters blueprints through public portfolio sets: All, Featured, Certified, and opt-in Labs
• syncs paginated hosted vocabulary content into a full slug-keyed local cache for offline guards and context generation
• validates, refreshes, and maintains decantr.essence.json

Security And Permissions

The CLI is intentionally a local project inspector and artifact writer. It reads selected project/workspace files, package manifests, routing/style/config files, .decantr artifacts, and Decantr cache/config files. It writes decantr.essence.json, DECANTR.md, .decantr/*, generated context packs, .decantr/graph/* typed graph artifacts, optional CI workflows/snippets, optional style/export files, and auth/telemetry config only when explicitly requested. decantr scan is the exception by design: it reads and prints only, and does not create .decantr, save reports, upload source, run package scripts, or install dependencies.

Telemetry is disabled by default. Hosted registry, hosted pack hydration, hosted critique/audit, and browser evidence are explicit command paths; screenshots and Evidence Bundles stay local unless a hosted workflow is invoked. Release audits prove the installed package with npm pack --dry-run --json. See security permissions.

suggest --from-code uses the selected app's source file to rank both hosted registry patterns and accepted project-owned local patterns, so Brownfield button/card/form law can surface from real code instead of just the text query.

Project Health And Studio

decantr verify is the workflow command most users should run locally after edits. It delegates to Project Health, can add Brownfield guard validation with --brownfield, requires an accepted local pattern pack with --local-patterns, scans .decantr/rules.json when present, supports workspace mode, and writes evidence to .decantr/evidence/latest.json by default when --evidence is used.

decantr doctor explains project/workspace state, adoption mode, adoption lane, generated artifacts, typed graph readiness, local law, visual evidence, design authority signals, CI wiring, and an ordered next-step queue. It is the command to reach for when an app is in a monorepo, has stale Decantr files, or someone is not sure what Decantr expects next.

decantr setup is non-mutating orientation. In an attached Brownfield app it reflects whether local law is already accepted, so the recommended verify command includes --local-patterns only when the project has that layer.

decantr ci is the blessed non-mutating automation gate. It runs the Project Health surface with adoption-mode-aware local law checks and emits a schema-backed CI report. decantr ci init writes root GitHub workflows or portable generic snippets using the detected package manager and pinned local CLI command instead of @latest; if the root manifest has not pinned Decantr yet, it prints the exact install command first.

decantr health remains the advanced project observability primitive. It composes the existing verifier audit, guard checks, brownfield route drift checks, runtime evidence, component reuse drift, accepted style bridge drift, accepted behavior-obligation checks, typed Contract graph freshness, and execution-pack files into a v2 ProjectHealthReport with status, score, route summary, pack summary, findings, stable diagnostic codes, typed repair IDs, evidence tier, authority resolution, loop readiness, and AI-ready remediation prompts. The graph freshness slice emits GRAPH001 / regenerate-typed-graph when an attached app has missing, stale, or non-derivable .decantr/graph artifacts. The component reuse slice emits COMP001 / import-existing-component when production source locally redeclares a common primitive that already exists as an exported reusable component, and COMP010 / replace-raw-control-with-local-component when production JSX renders generic raw controls such as <button> or text-like <input> while the project already owns a reusable primitive. Specialized inputs such as file, hidden, checkbox, radio, color, range, and Dropzone getInputProps() controls are not treated as generic Input drift. The behavior-obligation slice emits A11Y010, A11Y011, INT010, INT011, INT012, INT013, and COMP020 for high-confidence dialog/form regressions such as missing accessible names, missing label associations, missing visible destructive consequence copy, missing cancel affordances, missing submitting guards, implicit form button types, or bypassed project-owned interaction primitives. The style bridge slice emits TOKEN010 / replace-arbitrary-style-with-bridge-token when production JSX, common class helpers, hardcoded inline color styles, or hardcoded visual values in CSS/module stylesheets bypass .decantr/style-bridge.json after it has been accepted as project-owned style authority. The baseline slice emits VISUAL010 / review-visual-baseline-drift when --since-baseline detects changed screenshot hashes. When .decantr/graph/graph.snapshot.json exists, each finding is anchored to the most specific graph node Decantr can resolve, and JSON, markdown, text output, repair prompts, and Evidence Bundles carry that anchor. decantr graph also writes content-addressed history snapshots under .decantr/graph/snapshots/ so repeated graph runs can be replayed across an AI edit sequence. When .decantr/analysis.json exists, decantr graph links observed routes/pages to implementation source artifacts and links exported reusable component declarations to their source files. When browser evidence writes .decantr/evidence/visual-manifest.json, decantr graph ingests it as local route/page Evidence nodes without uploading screenshots. When .decantr/evidence/latest.json exists, decantr graph can also materialize saved findings, evidence strings, graph anchors, repair IDs, and referenced repair/read target files as typed graph nodes and edges. When .decantr/health-baseline-diff.json exists, baseline changed files become file-level temporal evidence in the graph.

decantr export --to figma-tokens

Use --json for machines and schema validation, --markdown for summaries, --evidence for the privacy-redacted Evidence Bundle, and --prompt <finding-id> when you want a scoped remediation prompt for an AI assistant. Use --diagnostics --json when automation or agents need the stable diagnostic code and repair ID catalog without running a project audit. The prompt command prints instructions only; it does not modify source files. In monorepos, prompt commands preserve --project <path>, include app-prefixed read targets such as apps/web/DECANTR.md, and use root-safe runtime commands such as pnpm --dir apps/web build so the finding resolves from the same app that produced it. Prompt output includes the stable code and repair ID; if decantr graph has generated a snapshot, it also includes the graph node ID, node type, confidence, and snapshot ID for the finding. --browser uses a project-local Playwright install and a supplied base URL to capture local route screenshots under .decantr/evidence/screenshots/ and write .decantr/evidence/visual-manifest.json; missing Playwright becomes a visible setup finding/message, not a crash or silent skip. --save-baseline writes .decantr/health-baseline.json; --since-baseline writes .decantr/health-baseline-diff.json with changed files, route impact, finding deltas, screenshot hash drift, and contract drift. --design-tokens <path> compares a Tokens Studio/Figma token JSON export against Decantr CSS token names. decantr ci --fail-on error fails only when blocking errors exist; decantr ci --fail-on warn also fails on warnings.

decantr ci init installs .github/workflows/decantr-ci.yml for GitHub Actions. The generated workflow installs dependencies at the workspace root, writes JSON/markdown CI artifacts, gates with decantr ci, appends the markdown report to the GitHub step summary, and uploads both files as artifacts. Use --force to replace an existing workflow or --fail-on warn for stricter repositories. In monorepos, add --project <path> from the repository root; dependency install stays at the root while CI evaluates the app contract and uploads app-scoped artifacts. Use --workspace to generate an aggregate gate. Use --provider generic for Jenkins, Please, Buildkite, GitLab, Azure DevOps, or internal deployment tools. Generated CI uses the pinned local package-manager command and does not depend on @latest. Project Health remediation prompts are also monorepo-aware, so missing-pack fixes use apps/web/decantr.essence.json and CI recommendations include --project apps/web.

decantr workspace is the monorepo reliability namespace. Before attach, workspace list shows app candidates. After attach, it also discovers Decantr projects from .decantr/workspace.json or by finding decantr.essence.json files, and it distinguishes "attach another app" from the empty-workspace first attach. Workspace health runs projects with deterministic ordering, concurrency, per-project timeout, failure isolation, and aggregate JSON, and can limit a run to changed projects:

decantr workspace list
decantr workspace health
decantr workspace health --json --output .decantr/workspace-health.json
decantr verify --workspace --changed --since origin/main

In observed Brownfield projects, common section shorthands are accepted for page and feature additions when they resolve unambiguously. For example, decantr add page app/settings --route /settings --project apps/web and decantr add feature saved-recipes --section app --project apps/web resolve app to the single primary section, such as observed-primary, so docs and LLM prompts do not have to guess generated section IDs first.

decantr studio starts a local-only Control Room powered by the same v2 report. It uses Node built-ins only and serves GET /, GET /api/health, GET /api/control-room, GET /api/resolve, GET /api/evidence, GET /api/graph-impact, GET /api/task-preview, GET /api/proof, and POST /api/refresh.

decantr studio
decantr studio --port 4319 --host 127.0.0.1
decantr studio --report decantr-health.json
decantr studio --workspace

Studio is for local triage, not Decantr admin telemetry. The Control Room keeps the first decision simple: inspect loop state, next action, authority lane, blocking findings, evidence tier, graph impact, and copyable commands. The views cover Control Room, Routes, Graph Impact, Authority Resolver, Evidence, Repairs, and CI/Benchmarks without uploading source code, prompts, file paths, or project data.

Workspace Studio uses decantr workspace health behind GET /api/workspace and POST /api/workspace/refresh so large monorepos can triage many Decantr projects from one local dashboard.

Use report mode for customer-controlled reporting from CI artifacts:

decantr health --json --output decantr-health.json
decantr studio --report decantr-health.json

If the project has explicitly enabled Decantr CLI telemetry, new --telemetry, init --telemetry, analyze, check --telemetry, health, and studio emit only aggregate product-activation metadata such as lifecycle command outcome, analyze counts, status, score, finding counts, CI failure outcome, Studio usage, and remediation prompt requests. They never upload the health report, finding evidence, local paths, route names, source code, package names, or prompt text.

Opted-In Telemetry Identity

decantr telemetry lets users inspect and link the opaque install/project ids used by opted-in CLI telemetry. This is how customer org attribution becomes durable without collecting repository names, local paths, source code, prompts, private package slugs, emails, or secrets.

decantr telemetry status
decantr telemetry status --json
decantr telemetry explain
decantr telemetry explain --json
decantr login --api-key=<key>
decantr telemetry link --enable --org <org-slug>

telemetry link calls the hosted /v1/me/telemetry-link endpoint with only opaque ids, optional org slug, and optional label. The API verifies org membership, writes telemetry_identity_aliases, clears the actor-resolution cache, audit logs the change, and emits telemetry.identity_linked.

telemetry explain prints the CLI event catalog subset, aggregate field categories, current opaque ids if they already exist, and the explicit never-collected list. It is designed for security review and customer trust conversations before a team opts in.

Content Health

decantr content check is the preferred content-author workflow for vocabulary repositories such as decantr-content. decantr content-health remains as a backward-compatible primitive. Content Health is separate from Project Health: Project Health checks an end-user app against its Decantr contract, while Content Health checks published content inputs before they flow into the hosted registry.

decantr content check
decantr content check --ci --fail-on error
decantr content-health
decantr content-health --json
decantr content-health --markdown --output content-health.md
decantr content-health --ci --fail-on error
decantr content-health --ci --fail-on warn
decantr content check --prompt <finding-id>

The report validates local patterns/, themes/, blueprints/, archetypes/, and shells/ against the published registry schemas, checks hard references such as blueprint themes and composed archetypes, summarizes softer generation-coverage gaps such as missing pattern coverage, and emits AI-ready remediation prompts. It does not call the hosted registry by default; use the existing registry drift audits when you need live publish parity.

Greenfield Certification

Use the built-in certification harness before releases when you want to prove that representative blueprints still scaffold into runnable starter projects:

pnpm --filter @decantr/cli certify:blueprints

By default it certifies portfolio, producer-studio, and agent-marketplace by:

• running decantr new in fresh temp directories
• seeding offline content from DECANTR_CONTENT_DIR or a sibling decantr-content checkout
• verifying the starter runtime files and router mode match the generated essence
• running npm run build in each scaffolded project

Override the matrix or emit JSON when needed:

pnpm --filter @decantr/cli certify:blueprints -- --blueprints=portfolio,legal-research --json

Offline blueprint scaffolding expects a real local content source:

DECANTR_CONTENT_DIR=/path/to/decantr-content decantr new my-app --blueprint=esports-hq --offline

If a requested offline blueprint, archetype, or theme cannot be resolved from local cache/custom content or DECANTR_CONTENT_DIR, the CLI now stops explicitly instead of silently falling back to the default scaffold.

Run decantr sync before offline-heavy or CI-heavy workflows that depend on hosted certified vocabulary content. Sync paginates the official registry list endpoints, then fetches and stores each item by slug as a full content record under .decantr/cache/@official/. That keeps guard checks, Project Health, and context generation aligned with the canonical vocabulary contract instead of abbreviated public list summaries.

Workflow Certification

The broader workflow matrix now has its own certification entrypoint:

pnpm --filter @decantr/cli certify:workflows

It covers:

• greenfield blueprint bootstrap
• greenfield contract-only
• brownfield adopt -> task -> verify, with analyze -> init --existing --accept-proposal -> check --brownfield still covered as primitives
• brownfield doctrine maps and contract coverage checks
• brownfield semantic route-domain sectioning
• direct brownfield compatibility init
• adoption modes (contract-only, style-bridge, decantr-css)
• offline contract-only and offline blueprint flows
• unsupported target contract-only fallback
• monorepo --project handling
• Next.js App Router adapter
• hybrid follow-up composition via Decantr mutation commands

Generated Context

Scaffolded projects include compiled execution packs under .decantr/context/, including:

• scaffold-pack.md / scaffold-pack.json
• section-*-pack.md / section-*-pack.json
• page-*-pack.md / page-*-pack.json
• review-pack.md / review-pack.json
• pack-manifest.json

Those files are the compact task contracts meant for AI assistants and downstream tooling.

Recommended read order for AI-assisted scaffolding:

1. DECANTR.md for the design spec, CSS approach, and guard rules
2. .decantr/context/scaffold-pack.md as the primary compiled shell, theme, feature, and route contract
3. .decantr/context/scaffold.md as the broader app overview and topology guide
4. matching section-*-pack.md and section-*.md files before section work
5. matching page-*-pack.md files before route work

Treat the compiled execution packs as the source of truth. Use the narrative docs as secondary explanation, start with the shell and route structure first, and run decantr check plus decantr audit after implementation.

For a broader health pass, run decantr verify after refresh or before opening a pull request, and run decantr ci inside CI. Install the default GitHub Actions gate with decantr ci init. Findings include remediation commands and can be turned into focused AI prompts with decantr health --prompt <finding-id>.

For cold-start harness or certification runs, use only the scaffolded workspace files as the contract. If local scaffold files disagree, stop and report the mismatch rather than relying on repo-global Decantr assumptions.
