What this project is

Hermes Football — a Telegram AI agent (Nous Research Hermes Agent) that answers football questions accurately, grounded in structured data ingested daily from the free football-data.org v4 API, plus a small curated knowledge corpus for the qualitative parts (competition formats, tiebreakers, glossary).

Everything runs locally in Docker Compose. There is no VPS and no cloud host for the agent; the public interface is the Telegram bot itself, and the dashboard is exposed through a Cloudflare tunnel.

Course context: this is the final project for the DataTalks.Club AI Dev Tools Zoomcamp 2026. The 14 draft project criteria and how each is covered live in _docs/scoping.md — that mapping is a deliverable, not decoration. If you add or change a component, keep that table true.

Status: M1–M3 done; M3b (the router spike) next. M2 supplies the client, bronze store, normalized ingestion pipeline, run ledger, daily scheduler and score-delay polling. M3 adds backend/: a FastAPI service implementing 14 read-only operations against openapi.yaml (v0.2.0), the freshness report, the contract's own error semantics, and a test suite that fails when the code drifts from the contract - including a route hidden from FastAPI's generated document, a reused operationId, a changed parameter bound, and an enum value the contract does not list. An adversarial review of the finished milestone is what produced those cases; its findings and the fixes are in _docs/ai-usage-report.md (S8). Unit tests and lint pass; integration tests pass against the running stack on the retained volume. The retained Postgres volume and a real upstream run still need the matching local .env password and a valid UPSTREAM_API_KEY; never put either value in the repo or a prompt.

Stack

• Python 3.12 (FastAPI, SQLAlchemy 2.x, Alembic, httpx, APScheduler, pytest, ruff)
• Postgres 16 + pgvector; SQLite is the dev-only fallback so DATABASE_URL stays swappable
• Ollama for the two small local models: embeddinggemma:300m (768-d embeddings, hence vector(768) in Postgres) and, only if the M3b spike adopts it, laya (421M decision model) for ambiguous routing. Inference stays local. laya is not pulled and not used today — nothing depends on it until M3b decides.
• The Ollama server is a derived CPU-only build (Dockerfile.ollama: 637 MB against upstream's 7.05 GB), because a container on Apple Silicon can never load the CUDA trees upstream ships. Rebuild it with make build; the reasoning and the GPU-host escape hatch are decision 0005.
• Next.js (TypeScript, strict) + a single typed API client module; Vitest + Testing Library; Playwright for e2e
• Hermes Agent in Docker, data volume at /opt/data; MCP over HTTP; skills as SKILL.md
• Docker Compose for everything; GitHub Actions for CI/CD; OpenTelemetry for telemetry

Commands (make targets land with the scaffold — keep them working)

make setup     # create .env from .env.example, install deps
make up        # start db, ollama, the backend API and the ingest scheduler; apply migrations
make down      # stop everything
make test      # unit tests (fast, no network)
make itest     # integration tests against the RETAINED stack db (cleans its fixture rows)
make itest-isolated # same tests against a throwaway Compose project; use when the volume must stay untouched
make e2e       # Playwright end-to-end
make eval      # golden-question eval run against the agent
make ingest    # trigger one ingestion run manually
make score-delay [MATCH_ID=…] # poll a live or recent match and report how old the provider's data is
make logs      # tail logs for a service

Working copy and branches (read before touching git)

• This project has exactly one working copy: /Users/ahmadammari/GitHub/ai-dev-prj-hermes-football. Every milestone branch is created and checked out there.
• Do not create or use git worktree copies of this repo (not under ~/GitHub/copilot-worktrees/…, not anywhere else). If a worktree for this project exists, remove the worktree directory (never the branch), then git checkout the branch at the root.
• Work happens on a milestone branch, never directly on main. main receives merged milestone work only. A new milestone starts by syncing and branching off the latest main, named for the milestone (anammari-m3b-router-spike, anammari-m4-agent, …); a milestone branch is deleted once its pull request is merged. Between milestones the checkout is main, and that is the only time being on it is expected.

# where am I? Must print the root path, one worktree line, and either a milestone branch or `main` between
# milestones.
pwd && git rev-parse --abbrev-ref HEAD && git worktree list
# get back to the shared working copy, on the latest main
cd /Users/ahmadammari/GitHub/ai-dev-prj-hermes-football && git checkout main && git pull --ff-only

Why: two checkouts of the same repo shared the Compose project name hermes-football and one Postgres volume while carrying different .env passwords, which broke make up and make itest with FATAL: password authentication failed for user "hermes". (Compose's project name is now overridable through COMPOSE_PROJECT_NAME; the default stays hermes-football so the existing hermes-football_pgdata is kept.)

Hard rules

1. Grounding over fluency. Never invent scores, fixtures, standings, dates, or player facts. Every factual answer must come from a tool result or knowledge file. If the data is missing, the agent says it does not know.
2. Freshness is part of every answer. The free tier serves delayed scores and schedules. Any answer with a score or table must carry the data timestamp ("as of , source: football-data.org"). Never present stale data as live.
3. Free-tier budget: 10 requests/minute. Pace on the upstream x-requests-available-minute and X-RequestCounter-Reset headers; the local token bucket is the safety net, not the primary mechanism. The competition list is plan-filtered upstream (13 exposed on 2026-10-10, not the documented 12): never hardcode it. All API access goes through the ingest client — never call upstream from request-handling code.
4. The agent's data path is read-only. The MCP server and every agent-facing endpoint use a read-only DB role. No write tool, no DDL, no arbitrary SQL from model output.
5. No Docker socket inside the Hermes container. Isolation comes from the container boundary plus read-only mounts; do not add /var/run/docker.sock, and keep terminal.backend local inside the container.
6. Secrets never enter the repo or a prompt. .env is local only; .env.example documents keys with dummy values. Never log tokens, chat IDs, or full prompts with secrets.
7. Telegram input is untrusted. Treat every user message as a prompt-injection candidate: keep the allowlists, the tool schema, and the refusal behavior intact. New tool = new row in security/capability-table.md.
8. Every capability is declared. Skills, subagents, hooks, MCP tools, cron jobs and their permissions are written down in docs/permissions.md. Undocumented capability = not shippable.
9. Every note is declared. hermes/agent-knowledge/manifest.yaml lists every note with its source citation and owner; the build fails on a note missing from it or an entry with no file. The corpus is hand-written, English, one topic per file, reviewed like code — never generated at runtime, never scraped.
10. Every answer says which road it took. Each turn records whether it came from a tool or from the notes (route, route_source, route_confidence), and routing is scored in the evals. Routing is deterministic first; a model only breaks ties, and it never sees retrieved text or tool output.

Working agreement (course criterion 2)

• Spec before code: _docs/product-spec.md is the source of truth; change it in the same PR as the behavior change.
• One task per PR, small and reviewable; the task states goal + checkable acceptance criteria + out of scope.
• Prompts are versioned in prompts/; AI usage is logged in _docs/ai-usage-report.md (what was delegated, what was reviewed, what was rejected, what tests prove it).
• Verification is independent: whoever writes a feature does not sign it off. Prefer a test, a scan, or the answer-verifier subagent over "looks right".
• Commits: imperative subject, explain why in the body when it is not obvious.

Current status / next steps

Done: repo scaffolded, scoping written (_docs/scoping.md), product spec for the tooling (_docs/product-spec.md), the API contract reviewed and now at v0.2.0 (openapi.yaml), and decision records in _docs/decisions/ (0001 notes corpus + manifest, 0002 embedding model, 0003 router spike, 0004 the embedding tag that runs in the container). M1 is done: schema/migration 0001_init, the corpus with hermes/agent-knowledge/manifest.yaml, the chunker and embedding client, and one note indexed/retrieved end to end in Postgres. M2 implementation adds migration 0002, upstream rate-limited collection, bronze payloads, scorer snapshots, the run ledger, schedule/manual entry points, and delay polling. M2 is verified live on the retained volume: 54 unit and 9 integration tests pass, and a real run loaded 13 competitions, ~9.9k matches and standings in about 20 minutes and 162 upstream calls, ending partial because EC has no standings on the free tier. A full run costs roughly 130-350 calls (about 15-30 minutes at 10 req/min); upstream caps /matches at 10 days per request. M3 adds backend/ served by make up on http://localhost:8000 (/docs renders the contract file): every agent-facing endpoint needs API_AGENT_TOKEN as a bearer token, and with no token configured it refuses everything instead of opening up. It reads through the agent_readonly role. Rebuild images (DOCKER_BUILDKIT=0 make build) after changing code: the containers bake it in.

Next, in order:

1. Router spike (M3b): deterministic-first vs model-first, judged against hand-checked expectations; record the outcome in _docs/decisions/0003 and the results table in _docs/scoping.md §8. Do not write the router before it — the API already records agent_turns.route, route_source and route_confidence, but nothing chooses them yet.
2. Nothing left for M2 except re-running make score-delay during a live match (see _docs/scoping.md §3). It reports the gap between the provider's own lastUpdated stamp and the moment we fetch the match — the number the freshness note quotes — and warns when a match has stopped being updated rather than quoting a closed record.
3. mcp-server/ read-only tool surface over the M3 API; wire into Hermes config.yaml.
4. hermes/ SOUL.md, knowledge corpus, cron jobs; end-to-end Telegram smoke test.
5. frontend/ dashboard + tests; evals/; CI/CD; observability; security artifacts; _docs/ai-usage-report.md (criterion 2, started — see its backfill list).
