Milestone #254 step 4 (#2290). Eleven capabilities, both surfaces, one service. Design systems are owner-scoped top-level records rather than project-scoped ones, so these do not nest under /api/projects/ the way systems do — routes/rulebooks.py was the closer shape. The one exception is the project pointer, which is genuinely about a project: PUT /api/projects/<id>/design-system, PUT rather than PATCH because clearing it is a first-class outcome and not an omission. `/resolved` and `/tokens` are deliberately separate endpoints. One answers "what does this system CHANGE", the other "what does it end up BEING", and a system that overrides nothing has an empty token list and a full resolved set. Shipping only one would have made the other a client-side computation of exactly the kind the record model exists to remove. ResolvedToken.to_dict carries the SHADOWED contributions, not just the winner. Dropping them at the serialisation boundary would have discarded the one thing step 2 was built to preserve, and it would have been invisible — the payload still looks complete. Three sentinel translations on the MCP side, each tested, because an agent cannot omit an argument and a wrong mapping here is silent: - parent_id: 0 = unchanged, -1 = clear (become a family system), positive = set. Renaming a system must not silently re-root it. - order_index: -1 = unchanged, since 0 is a valid position. - value_by_mode: guarded on `is not None`, not truthiness, so `{}` can strip every mode from a token instead of being unreachable. DesignSystemCycle maps to 400 on REST and to a ValueError carrying the message on MCP — kept apart from 404 throughout. An agent told "not found" retries the same call; one told what the loop is can fix it. Two structural guards beyond the parity list: every endpoint must be reachable on the app (catching a decorator copied without its path, where the second handler silently never runs), and every public coroutine in the tools module must be registered (a tool written but never registered is invisible to an agent, and nothing else would notice).
Fabled Scribe
A self-hosted work system-of-record for software projects, built to be driven by Claude Code. Notes, tasks, issues, projects, milestones, rules, and stored processes — reachable from Claude via a built-in MCP endpoint and a bundled Claude Code plugin, with a clean web UI for humans. No in-app LLM; Claude is the sole assistant.
Features
Notes and tasks with a Markdown editor, sub-tasks, milestones, issues, and kanban project workspaces. Stored processes, an engineering rulebook system, and semantic search with proactive knowledge-injection into Claude's context. A knowledge graph, per-user/group sharing, and a built-in MCP server (/mcp) plus a bundled Claude Code plugin so Claude can record and recall your work directly.
Quick Start
Prerequisites: Docker and Docker Compose. No GPU or local model needed — Claude is the sole assistant, reached over MCP.
Download docker-compose.quickstart.yml from this repo, then:
# Optional but recommended — set a secret key
export SECRET_KEY=your-random-secret-here
docker compose -f docker-compose.quickstart.yml up -d
Open http://localhost:5000. The first user to register becomes admin. To connect Claude, create an API key under Settings → API Keys and install the Claude Code plugin — see API Keys & MCP.
Development: To build from source, see Development.
