</> Delimit

The merge gate for AI-written code, with signed, replayable attestation.

Wrap any AI coding assistant (Claude Code, Codex, Cursor, Gemini CLI) with a governance chain that runs your gates, records what changed, and signs a replayable receipt for every merge.

                       receipt → .delimit/attestations/att_a05050eb8e13277e.json

Every wrapped run emits a local delimit.attestation.v1 bundle: repo head before/after, changed files, gate results, and an HMAC-SHA256 signature. Verify it offline with delimit seal-verify; hosted replay is not available yet. Advisory by default; flip to enforcing when you're ready.

Fastest path to value: delimit check

Zero-config PR safety gate. No init, no setup, no account, no keys — run it on any repo and it applies deterministic checks (breaking API changes + leaked secrets) to your staged or modified files.

npx delimit-cli check

$ delimit check

  Delimit Check

  Policy: default | Base: HEAD | Specs: 1

  + api/openapi.yaml — clean

  PASSED — no breaking changes, no leaked secrets

When a check finds a breaking change or a leaked secret, it prints the offending file and the issue and exits non-zero — so it drops straight into a pre-commit hook or CI step.

Common options:

delimit check --staged          # only check staged files
delimit check --base main       # compare against a git ref (default HEAD)
delimit check --fix             # show migration guidance for violations
delimit check --record          # write a content-pinned record of this check

--record writes a content-pinned record of the check to .delimit/records/check-<ts>.json (or a path you name). That record is the precursor to the signed, replayable Seal attestation — the same evidence shape, pinned to the exact content you checked.

Golden Path — your first 10 minutes

The merge gate for AI-written code, end to end: lint a spec, see exactly what breaks, classify the bump, settle the hard calls with multiple models, and walk away with a signed, replayable attestation. Then keep the context that survives across sessions and models.

1. Install

npx delimit-cli scan          # discovery: finds your OpenAPI specs, frameworks, security issues, tests
npx delimit-cli init          # wire up the merge-gate config (--preset strict | default | relaxed)

scan (delimit_scan) reports what Delimit can do for this repo. init (delimit_init) drops in the policy preset and merge-gate config. No account, no keys.

2. The merge gate, end to end

Lint the spec change (the gate). Baseline vs. proposed, with policy applied — one pass/fail verdict.

npx delimit-cli lint old.yaml new.yaml       # tool: delimit_lint

See exactly what breaks. Pure structural diff — added/removed/modified endpoints, schemas, params, no policy.

npx delimit-cli diff old.yaml new.yaml       # tool: delimit_diff

Classify the bump. Deterministic MAJOR/MINOR/PATCH/NONE — same input, same answer, every time.

delimit_semver       → MAJOR/MINOR/PATCH/NONE + next version string
delimit_impact       → blast radius: scans your dependency manifest for downstream callers (informational)

Settle the hard calls. When the gate verdict is a judgment call, put it to multiple models and let them debate to consensus.

npx delimit-cli deliberate "Is dropping the deprecated v1 /users field a safe MINOR?"
#   tool: delimit_deliberate — 3 hosted runs after `delimit signin` (free account), then bring your own keys

delimit setup gives the Codex MCP server a 30-minute tool timeout so a multi-round panel can return its completed transcript instead of being detached by the client while its models are still responding.

Capture the signed, replayable attestation. After a gate event (deploy / security / test / audit), record the evidence bundle and verify it any time.

delimit_evidence_collect   → signed evidence bundle for the audit trail        (Pro)
delimit_evidence_verify    → confirm a bundle hasn't been tampered with         (Pro)
delimit_seal_verify        → check a Delimit Seal receipt against its bundled   (Free)
                             Layer-0 constitution — offline-verifiable

Every receipt is offline-verifiable with npx delimit-cli seal-verify <receipt.json>. Hosted receipt replay is not available yet.

3. Context that survives sessions and models

Decisions, constraints, and tasks persist across sessions and across AI assistants — switch from Claude Code to Codex, Cursor, or Gemini CLI without losing the thread.

Memory — persist and recall the why, not just the diff.

npx delimit-cli remember "v1 /users field is frozen until Q3 — downstream billing depends on it"
#   tool: delimit_memory_store
npx delimit-cli recall billing               # local recall over your saved memories (Free)

For semantic recall by meaning across sessions, the assistant calls delimit_memory_search (Pro) directly.

Ledger — one task list, shared across every assistant and session.

delimit_ledger_add        → record a task/bug/feature/strategic item
delimit_ledger_context    → session-start: top open items by priority (what's queued)
delimit_ledger_done       → close with a note (auto-captures a PR URL as ship proof)

That's the loop: gate the change, sign the proof, keep the context. Run it once on a real spec and you've used the whole merge gate.

Explicit Copilot CLI and Muse Code sessions

Install and authenticate the official client separately, under the same OS user who runs Delimit. Delimit does not install these clients, purchase a plan, log you in, or verify your subscription allowance. Then launch from the actual Git repository, not your home directory:

cd /path/to/repository
npx delimit-cli chat --model copilot
npx delimit-cli chat --model muse

These are explicitly selected interactive harnesses, not new model votes or automatic build-loop backends. Neither launch probes other models or falls back to another provider. Native permission approvals remain active. Copilot launches with automatic updates and remote/export features disabled for this session.

Muse preparation: first verify that your account permits Standard muse-spark-1.3 on the intended billing route. Back up your native $XDG_CONFIG_HOME/muse/settings.json (or ~/.config/muse/settings.json when XDG_CONFIG_HOME is unset), and merge these fields into its existing JSON object; preserve unrelated settings and authentication:

{
  "model": "muse-spark-1.3",
  "context": {
    "foreign_personal_rules": false,
    "foreign_personal_skills": false
  }
}

The explicit Muse launch requires that selection and exclusion of foreign personal rules/skills; it does not change native settings for you. A configured provider must be meta, and a configured endpoint must be https://api.meta.ai/v1. META_API_KEY or MODEL_API_KEY environment overrides block this launch until you resolve the intended billing route. Do not switch credentials or models merely to bypass that check. Standard selection is not proof of zero retention, subscription billing, or private-data clearance.

Current binary discovery supports Copilot in ~/.local/bin, /usr/local/bin, or /usr/bin, and Muse's versioned ~/.local/bin/muse-bin-<version>-R<revision> distribution. Muse uses that executable directly, not its updater launcher. Other installation layouts are not automatically discovered. The native Muse context settings were checked with Muse Code 1.2.1; recheck compatibility when upgrading the client.

Delimit supplies a compact project-bound startup instruction, not an automatic import of your ledger, memory, or complete conversation. Optional local guidance can live in $DELIMIT_HOME/harness-bootstrap.md (default ~/.delimit/harness-bootstrap.md); the combined startup text must fit within 16 KiB. Project AGENTS.md/CLAUDE.md files at or above 64 KiB are rejected instead of silently truncated. Recover and save a scoped handoff through your available Delimit tools. These launchers do not automatically register a native MCP connection or prove cross-harness continuity.

When both project instruction files exist, the startup packet lists both files with their sizes and hashes and tells the harness to read them completely, including guidance hidden by native file precedence. It does not copy their contents into the startup packet, silently merge files, or override the existing instruction hierarchy. User-global guidance remains opt-in through the local bootstrap file; Delimit never copies a different client's private rules by default. This manifest is a loading instruction, not proof that the model performed every read. If required guidance is inaccessible or conflicts, resolve that gap before allowing edits. Oversized native project files still fail closed without rewriting the originals.

Optional command shims can be installed with delimit setup --harness-shims. Ordinary setup only refreshes already-managed Muse/Copilot shims; it does not newly shadow your native commands. Custom shims are preserved. With the opt-in, a conflicting custom file stops installation of both additional shims.

For existing launcher-managed continuity, clean exit finalizes only a bound handoff. If that is unavailable, Delimit reports the specific reason and writes a private local diagnostic receipt under its sessions/ directory. That receipt is not a conversation backup. Existing handoffs are not replaced by empty ones; resume the exact native session and explicitly save a project-bound handoff.

Think and Build

Beyond the merge gate, Delimit orchestrates multi-model deliberation and autonomous builds. delimit think dispatches a strategic question to Claude, Codex, Gemini, and Grok; delimit build activates a background daemon that executes ledger tasks through the gate chain. delimit vault manages local secrets (AES-256).

Works across any configuration, from a single model on a budget to a full panel.

What's New

Gate every AI-assisted invocation. Ship the receipts.

• delimit wrap — pipe claude -p, cursor, aider, codex, or any AI-assisted CLI through a signed governance gate. Snapshots the git diff before/after, runs lint + tests, HMAC-signs an att_* attestation, and writes the receipt locally for offline verification. Advisory by default; --enforce blocks CI on policy violations; --max-time <s> is a kill switch that tags the attestation as a liability_incident and prints a cross-model handoff command.
• delimit trust-page — renders a directory of attestations into a static HTML trust page + JSON Feed 1.1 feed. Single file, no framework, offline-renderable. Deploy anywhere.
• delimit ai-sbom — aggregates attestations into a CycloneDX 1.6 bill-of-materials with AI-specific fields (detected models per vendor, tool-call surface, policy gate counts). Pipe straight into procurement.
• Cross-model by construction — wrap is agnostic to the producer. Same attestation schema whether the pipe upstream is Claude Code, Cursor, Aider, Codex, or Gemini CLI. Switch producers without losing the audit chain.

# Gate any AI-assisted CLI
delimit wrap -- claude -p "add tests for payments"
#   → att_7d556843c84fb881 signed, receipt written locally

# Kill switch + handoff after 60s wall-clock
delimit wrap --max-time 60 -- cursor edit "refactor auth middleware"
#   → if killed: kind=liability_incident
#   → suggested: delimit wrap -- claude -p "refactor auth middleware"

# Render accumulated attestations as a public trust page
delimit trust-page -o ./trust
#   → ./trust/index.html (+ feed.json)

# Build a CycloneDX-AI bill of materials
delimit ai-sbom -o ./ai-sbom.json
#   → components: 4 models detected, 187 gates run

Earlier releases

The highest state of AI governance — earlier features still active.

• delimit doctor -- 14 prescriptive diagnostics. Every failure prints the exact command to fix it. --ci for pipelines, --fix for auto-repair.
• delimit simulate -- policy dry-run. See what would be blocked before you commit. The terraform plan for API governance.
• delimit status -- visual terminal dashboard. Policy, specs, hooks, CI, MCP, models, memory, ledger, evidence, git branch. --watch for live refresh.
• delimit report -- governance report. --since 7d --format md|html|json. Audit-friendly output for PRs and compliance.
• Memory hardening -- SHA-256 integrity hash + source model tag on every remember. Cross-model trust, verified on every recall.
• Tag-based publishing -- automated gateway sync, no more version drift between source and npm bundle.

Multi-Model Deliberation

Run your question through 4 AI models simultaneously. They debate each other until unanimous agreement.

delimit deliberate "Should we build rate limiting in-house or use a managed service?"

  Round 1 (independent):
    Claude:  Build in-house. Redis sliding window is 50 lines.
    Gemini:  Build. You already have Redis.
    Codex:   Agree — but add circuit breaker for Redis failures.
    Grok:    Build. Managed service costs $200/mo for 50 lines of code.

  Round 2 (deliberation):
    All models: AGREE

  UNANIMOUS CONSENSUS (2 rounds, confidence 94/100)
  Build rate limiting in-house with Redis + circuit breaker.

3 free deliberations, then BYOK for unlimited. Works with Grok, Gemini, Claude, GPT-4o.

v4.18

• MCP Registry record published on every release -- the official registry entry now tracks the npm version automatically. Publisher pinned and checksum-verified; the tag gate asserts that both server.json version fields match the package version.
• Tool descriptions -- 16 previously undocumented parameters documented from their signatures; 26 Pro-gated tools state the prerequisite and the unlicensed-call response.
• Release guards -- bundle-classification guard no longer flakes on SIGPIPE.

v4.17

• Cross-model continuity on fresh installs -- delimit_soul_capture / delimit_revive work without any internal modules via the public session_continuity module; captured souls carry deterministic provenance (venture, transcript identity, capture key) for reliable resume across model switches. Existing soul files load unchanged.
• Security audit -- fewer false positives on test fixtures and documentation dummies; suppressed findings are reported, never silently dropped.

v4.16

• Fail-closed bundle allowlist -- the npm package ships only explicitly reviewed gateway files; two CI guards block any unclassified or non-allowlisted file from entering the tarball.
• Session-end auto-capture installs in the settings shape Claude Code expects, so end-of-session handoff fires instead of being silently dropped.
• Always-on commit-author audit workflow catches identity drift on the repo.

v4.1

• TUI -- terminal-native Ventures panel, real delimit think and delimit build commands
• Security hardening -- notify.py stubbed in npm, axios pinned against supply chain attacks
• Free tier restructure -- deliberations use Gemini Flash + GPT-4o-mini (cost: <$20/mo)
• Zero-config onboarding -- auto-detect framework, scan, and first evidence in one command
• Auto-approve tools -- delimit setup configures permissions for Claude Code, Codex, and Gemini CLI

v4.0

• Toolcard Delta Cache -- SHA256 schema hashing, delta-only transmission, saves tokens
• Session Phoenix -- cross-model session resurrection with soul capture
• Handoff Receipts -- structured acknowledgment protocol between agents
• Cross-Model Audit -- 3 lenses (security, correctness, governance) with deterministic synthesis
• 4-model deliberation -- Claude + Grok + Gemini + Codex debate until consensus
• Universal Swarm Triggers -- "Think and Build", "Keep building", "Ask Delimit"
• Full governance toolkit -- lint, diff, policy, evidence, drift, attestation, and swarm orchestration exposed as MCP tools and CLI subcommands

Adopt with minimum privilege

You don't have to trust a large tool surface on day one. The safe on-ramp:

Phase 1 — read-only governance (free, no account). Start with the tools that only read your repo and write reports: delimit_lint, delimit_diff, delimit_semver, delimit_policy, delimit_explain, delimit_scan, and delimit_seal_verify. If your MCP client supports per-tool allowlists, grant exactly those. Nothing in this set executes, deploys, or posts anywhere.

Phase 2 — opt into side effects deliberately. Tools that write evidence bundles, open PR comments, or run deploys (delimit_security_audit, delimit_deploy_*, agent orchestration) are tier-gated; enable them once phase 1 has earned its keep in your CI.

Pin the Action to a commit SHA. @v1 is a floating tag. For supply-chain-sensitive pipelines, pin the exact commit and bump on review:

- uses: delimit-ai/delimit-action@<commit-sha>   # gh api repos/delimit-ai/delimit-action/git/refs/tags/v1

Keep BYOK keys out of plaintext config. If you bring your own model keys for deliberation, store them with delimit_secret_store (encrypted vault, access-logged via delimit_secret_access_log) rather than in dotfiles.

Our own releases ship under the same discipline: every release carries a signed, replayable Seal receipt (see the latest release assets — verify with npx delimit-cli seal-verify <receipt.json>), plus SLSA provenance on npm.

What the MCP toolkit adds

When installed into your AI coding assistant, Delimit provides tools across two tiers:

Free (no account needed)

• API governance -- lint, diff, policy enforcement, semver classification
• Persistent ledger -- track tasks across sessions, shared between all AI assistants
• Zero-spec extraction -- generate OpenAPI specs from FastAPI, Express, or NestJS source
• Project scan -- auto-detect specs, frameworks, security issues, and tests
• Quickstart -- guided first-run that proves value in 60 seconds

Pro

• Multi-model deliberation -- AI models debate until they agree (free: Gemini Flash + GPT-4o-mini; BYOK: any models)
• Security audit -- dependency scanning, secret detection, SAST analysis
• Test verification -- confirms tests ran, measures coverage, generates new tests
• Memory & vault -- persistent context and encrypted secrets across sessions
• Evidence collection -- governance audit trail for compliance
• Deploy pipeline -- governed build, publish, and rollback
• OS layer -- agent identity, execution plans, approval gates

What It Detects

28 change types (17 breaking, 11 non-breaking) -- deterministic rules, not AI inference. Same input always produces the same result.

FAQ

How does this compare to Obsidian Mind?

Obsidian Mind is a great Obsidian vault template for Claude Code users who want persistent memory via markdown files. Delimit takes a different approach: it's an MCP server that works across Claude Code, Codex, Gemini CLI, and Cursor. Your memory, ledger, and governance travel with you when you switch models. Delimit also adds API governance (28-type breaking change detection), CI gates, git hooks, and policy enforcement that Obsidian Mind doesn't cover. Use Obsidian Mind if you're all-in on Claude + Obsidian. Use Delimit if you switch between models or need governance.

Does this work without Claude Code?

Yes. Delimit works with Claude Code, Codex (OpenAI), Gemini CLI (Google), and Cursor. The remember/recall commands work standalone with zero config. The MCP server integrates with any client that supports the Model Context Protocol.

Is this free?

The free tier includes API governance, persistent memory, zero-spec extraction, project scanning, and 3 multi-model deliberations. Pro ($10/mo) adds unlimited deliberation, security audit, test verification, deploy pipeline, and agent orchestration. Premium ($50-100/mo) adds priority support and team features. Enterprise is custom: see delimit.ai/pricing.

Telemetry & cloud sync

Short version: none by default. Nothing leaves your machine unless you explicitly configure it.

What's always local (source of truth):

• ~/.delimit/events/events-YYYY-MM-DD.jsonl — per-tool-call events (tool name, timestamp, status, model id, session id, trace id). No source code, no prompts, no responses.
• ~/.delimit/ledger/ — your ledger items, work orders, deliberation transcripts.
• ~/.delimit/attestations/ — delimit wrap output bundles.

What's OPT-IN (requires you to provide your own Supabase project credentials):

• gateway/ai/supabase_sync.py mirrors the local event + ledger + work-order + deliberation rows into a Supabase project you own so you can view them in app.delimit.ai. It only activates if you set SUPABASE_URL + SUPABASE_SERVICE_ROLE_KEY environment variables OR provide ~/.delimit/secrets/supabase.json with those credentials. No URL or key is hardcoded in the published package (verify with grep -r aqbdqxnhzqzswdxifksc $(npm root -g)/delimit-cli/ — zero hits).
• Data scope when enabled: metadata only (tool names, timestamps, IDs, statuses, venture tags). Never source code, prompts, or model responses.

Kill switch: Set DELIMIT_DISABLE_CLOUD_SYNC=1 in your environment to force all sync operations to no-op even if credentials are present. Local files continue to work normally.

# Disable cloud sync for a single invocation
DELIMIT_DISABLE_CLOUD_SYNC=1 delimit lint api/openapi.yaml

# Disable for the shell session
export DELIMIT_DISABLE_CLOUD_SYNC=1

Webhook notifications: gateway/ai/notify.py emits governance events to a webhook endpoint only if you configure DELIMIT_WEBHOOK_URL explicitly. Unset by default.

If you spot another code path that could phone home without disclosure, file an issue. This section is maintained as ship-truth, not aspirational.
