# Marchwarden — Project Context

## What This Is
A network of agentic research specialists (MCP servers) coordinated by a
principal investigator (PI) agent. Educational project learning agents, MCP,
and agent composition.

## Current Project State

| | |
|---|---|
| **Phase** | Phase 1 complete, Phase 2 next |
| **Last worked on** | 2026-04-08 |
| **Last commit** | `7088f45` — Merge PR #7: M1.4 MCP server |
| **Branch** | `main` (clean) |
| **Tests** | 81 passing |
| **Blocking issues** | None |

## Key Files

| File | Purpose |
|---|---|
| `researchers/web/models.py` | Research Contract v1 Pydantic models (9 types) |
| `researchers/web/tools.py` | Tavily search + URL fetch with content hashing |
| `researchers/web/trace.py` | JSONL trace logger |
| `researchers/web/agent.py` | WebResearcher — inner agentic loop |
| `researchers/web/server.py` | FastMCP server wrapping the researcher |
| `cli/main.py` | CLI shim (not yet implemented) |

## Architecture

- **Researcher** = MCP server exposing `research(question) -> ResearchResult`
- **ResearchResult** = answer + citations (with raw_excerpt) + categorized gaps +
  discovery_events + open_questions + confidence + confidence_factors + cost_metadata + trace_id
- **Agent loop** = Claude tool-use loop (plan→search→fetch→iterate) + synthesis step
- **Trace** = JSONL audit log per research call at `~/.marchwarden/traces/`

## Conventions

- API keys live in `~/secrets` (not `.env`)
- Wiki is at `docs/wiki/` (local git clone, not MCP — wiki MCP is buggy)
- All merges via Forgejo API (claude-code user can't merge via MCP)
- One branch per concern, merge via PR, delete branch after

## Session Log

| Session | Date | Summary |
|---|---|---|
| 1 | 2026-04-08 | Project creation, naming, contract design, Phase 0 + Phase 1 complete (81 tests) |

## What's Next

**Phase 2: CLI Shim**
1. M2.1 — `marchwarden ask "question"` command (Click CLI, pretty-print)
2. M2.2 — `marchwarden replay <trace_id>` command
3. M2.3 — First smoke test: "What are ideal crops for a garden in Utah?"
