Forge Doctor API

Deterministic, offline-first, evidence-first engine for API architecture intelligence.

Forge Doctor ("the Doctor") inspects API projects — contracts, source code, configuration, and exported runtime artifacts — and produces structured, evidence-bearing findings. It never calls a model, never fetches a URL, and never guesses: anything it cannot establish from local evidence is surfaced as an explicit UnknownFact.

Status: 0.2.0 — the full deterministic surface is implemented (scan, diff, diagnose, inventory, lab, handoff). This is not a stable public API commitment; interfaces may still change before 1.0.

Design principles

The Doctor is the deterministic half of the Forge product family: it observes and classifies. Agentic code generation lives in api-forge (a separate project); this repository has no dependency on it.

Installation

pip install .            # runtime deps: typer, rich, pyyaml
pip install .[graphql]   # optional: graphql-core for GraphQL parsing

Requirements: Python >= 3.11. For development:

pip install pytest ruff mypy types-PyYAML build
python -m pytest -q
python -m ruff check .
python -m mypy src

Portable install (Forge contract)

The checkout also carries the Forge family's portable-installation contract — clone once, setup once:

./setup.sh          # or .\setup.ps1 — venv + wheel + ~/.forge registry

Installing the Forge into a consumer project (managed .mcp.json key + AGENTS.md marker block, sha256-ledgered) is deliberately a checkout script, not a forge-doctor-api verb: the package boundary bans os/subprocess imports across src/ and the 0.2.0 RC window forbids new CLI commands. Same verbs, same receipts as sibling forges:

python scripts/forge_install.py install --dry-run   # plan only
python scripts/forge_install.py install --yes       # apply to a repo
python scripts/forge_install.py status|doctor|repair
python scripts/forge_install.py uninstall [--purge]
python scripts/forge_install.py update|mcp-verify

# Optional local web UI over the same real services (127.0.0.1, session token)
python scripts/forge_portal.py [--no-browser] [--port N] [--root DIR]

theforge install auto delegates here automatically via the install_command field in forge.json.

Quickstart

# Full deterministic scan of a project directory
forge-doctor-api scan ./my-service

# Scan + CI gate: fail on new breaking changes vs a baseline contract
forge-doctor-api scan ./my-service --fail-on breaking --baseline ./last-release

# Emit SARIF for GitHub code scanning, or a compact agent-readable format
forge-doctor-api scan . --format sarif --out results.sarif
forge-doctor-api scan . --format agent

Exit codes: 0 scan ran and gate passed · 1 gate failed · 2 usage/misconfiguration error.

What it understands

• Contracts: OpenAPI 3.x (YAML/JSON), AsyncAPI, GraphQL SDL + introspection, gRPC .proto.
• Source: FastAPI route discovery, client call-site extraction (Python/JS/TS), GraphQL client queries (gql tagged literals).
• Config: timeouts, retries, rate limits, idempotency headers, authentication/CORS/mTLS/TLS evidence, gateway routes, ownership files, policy files.
• Runtime: OTLP/OTEL JSON traces, access-log records — ingested as compact per-request summaries (raw spans are not retained).

From those inputs it produces: OAS/ASYNC/GQL/GRPC contract checks, contract-drift and semantic compatibility diffs, client impact and blast radius, versioning/deprecation analysis, observability + performance regression findings, reliability checks (retry amplification, SLO budgets), passive OWASP API Top-10 candidates, policy violations, an API digital twin, root-cause diagnosis, safe-fix classification, multi-repo workspace analysis, fleet intelligence, migration portability assessments, and compact handoff bundles for agentic tools.
