Shipwright
- What it is
- An agent that takes an approved GitHub issue and returns a tested, reviewable pull request.
- Read first
- The agent runner's test suite, which exercises the plan, patch, and review loop end to end.
What’s live, what’s open source, and what stays private.
Three ledgers, checked in your browser: repositories you can read, demos you can open, and the private systems behind the case studies. Deeper backend checks live in the demo operations page.
Open source
Every entry names the file worth reading first. Entries tagged cold-clone reviewed were verified by an independent engineer working from a fresh clone before the repository went public. Claude plugin packs and demo-only repos stay on the GitHub profile and the live-demo ledger below.
Holdfast
- What it is
- An append-only decision ledger with a human publish gate, enforced inside Postgres by triggers, a hash chain, and unique indexes.
- Read first
- Attack tests that try to rewrite history and race two sessions against the publish gate; the migrations under them close what the tests document.
Vouch
- What it is
- Human review as an API: agents submit work, real reviewers return a consensus verdict.
- Read first
- A README walkthrough of the offline verification harnesses, with a 173-test suite behind it.
Matchbox
- What it is
- Disposable cloud dev servers that destroy themselves when a lease expires and write receipts proving it.
- Read first
- A hermetic reaper suite covering lease expiry, escalation, and the receipts a destroyed server leaves behind.
Tenantwell
- What it is
- Postgres row-level-security multi-tenancy, tested by an adversarial suite that attempts cross-tenant reads.
- Read first
- SQL attack tests that probe the tenant boundary from inside a session, including the one documented way across it.
Reconciler
- What it is
- Finds billing discrepancies, proposes typed fixes, and requires a person to approve every invoice change.
- Read first
- The verification workflow CI runs on every push, plus a README that walks the local run.
Landfall
- What it is
- Migrates a WordPress export to Astro and fails the build when any origin URL is missing from the built site.
- Read first
- Parity tests plus the synthetic Harborline fixture the verifier runs against. No client URLs are in the repository.
RepoMan
Grades a codebase's technical debt and prices the paydown.
Marrow
Turns AI coding-session transcripts into durable, searchable lessons.
Winnow
Scores and routes inbound leads; a 24-case model eval suite gates every accuracy change.
Muster
A terminal dashboard for running a fleet of AI coding agents in tmux.
Broadside
Fans one prompt out to a fleet of AI coding agents in tmux panes, then collects their work.
Yardmaster
One CLI that routes a prompt to Claude, Codex, Cursor, or Gemini, with JSON output and real exit codes.
Pairwell
PostgreSQL fuzzy matching for public filings, with hermetic SQL assertions and a bounded live demo on Texas open data.
Deckhand
An autonomous coding agent that works a Linear backlog end to end and opens the pull requests.
Throughline Connector Kit
The sanitized public kit behind Throughline: one four-method connector contract, the sync engine, sample CRM data, and tests.
Trifold
One Zod-validated operation registers as an HTTP route, a CLI command, and an opt-in MCP tool, with OpenAPI emitted from the same registry.
Vaultkeep
Reads, injects, and exports 1Password secrets from the command line so they never have to sit in a committed .env.
Gradewell
Scores Claude prompts against a stored eval suite, with string-match or rubric grading you can re-run.
Onward
A Claude Code stop hook that sends the agent back to work when the last turn still lists next steps, and stops when it is asking you a question.
Placard
Forty-nine MCP tools over Meta's Marketing API, with a smoke test that starts the server and lists every tool without credentials.
Showwright
Compiles a JSON show definition into a vMix preset bundle a studio machine can open.
Dowser
Suggests the next Claude Code skill from a local library using fuzzy search, TF-IDF, and optional embeddings.
polycast
One command definition writes Raycast, PopClip, Dropzone, and Shortcuts artifacts, and will not emit a surface that cannot represent that command's input.
xair-cli
Drives Behringer X Air and Midas MR mixers from the terminal, and a parity test fails the build if the docs drift from the CLI.
Outfitter
Claude Code plugin packs for building, testing, and deploying, where CI runs the plugin validator over every pack on every push.
llm-1password
Resolves llm model keys from 1Password at prompt time. refs.json stores the op:// reference; a failed read aborts the call.
The rest of the public estate lives on the GitHub profile.

Private systems
The production systems stay private; their case studies name what each claim rests on. The repositories above show the same engineering in the open.
