# State Hub MCP — Tool Reference Card

Quick reference for all tools and resources.

## Design Boundary

The State Hub is a **read model**. It observes and visualises cross-domain state
that originates in the projects themselves.

Two write operations are permanently sanctioned:

| Use Case | Tools |
|---|---|
| **Resolving Decisions** | `resolve_decision()` — decisions are cross-cutting; resolution must propagate across all domains |
| **Suggesting Next Steps** | `get_next_steps()` *(v0.2)* — surface what is unblocked; the domain does the work |

All other mutate tools are **bootstrap-only**: use them during First Session Protocol
to give a freshly-registered project its initial workstream structure.
Do not use them as a substitute for formal work definition inside the domain repo.

---

## Query Tools (read-only, use freely)

| Tool | Key Args | When to use |
|------|----------|-------------|
| `get_domain_summary(domain_slug)` | `domain_slug`: e.g. `"railiance"` | **Domain session start.** Scoped snapshot: active workstreams, blocking decisions, last 5 events, repo SBOM status — ~10% of get_state_summary() token cost. |
| `get_state_summary()` | — | **Cross-domain work / custodian sessions.** Full snapshot: totals, all blocking decisions, all blocked tasks, all open workstreams, last 20 events. Large (~10k tokens). |
| `get_topic(slug)` | `slug`: e.g. `"markitect"` | Deep-dive on one topic + its workstreams + recent events. |
| `list_tasks(workstream_id, status?)` | `workstream_id`: UUID (required); `status?`: todo/in_progress/blocked/done/cancelled | List all tasks in a workstream. Use this to look up task UUIDs before calling `update_task_status`, or to verify which workplan tasks are already synced to the DB. |
| `list_blocked_tasks(workstream_id?)` | optional filter | Surface all impediments, optionally scoped to one workstream. |
| `list_pending_decisions(topic_id?)` | optional filter | Decisions holding up work, sorted by deadline. |
| `get_recent_progress(limit, since?)` | `limit` default 20; `since` ISO datetime | Reconstruct recent session history. |

---

## Sanctioned Write Tools

| Tool | Key Args | Notes |
|------|----------|-------|
| `record_decision(title, ...)` | `decision_type`: made/pending; `topic_id?`; `workstream_id?`; `deadline?` | Financial/legal + pending → auto-escalated per constitution §4. At least one of topic_id/workstream_id required. |
| `resolve_decision(decision_id, rationale, decided_by)` | all required | Marks decision resolved, emits progress event, writes DECISIONS.md to project directory. |
| `add_progress_event(summary, ...)` | `event_type`: note/milestone/blocker/insight; `topic_id?`; `workstream_id?`; `task_id?`; `detail?` | Append-only log entry. **Use at session end.** |

---

## Bootstrap-Only Tools

> Use during **First Session Protocol** to give a freshly-registered project its
> initial workstream structure. Do not use for ongoing project management —
> formal work structure belongs in the domain repo (workplans, requirements, milestones).

| Tool | Key Args | Notes |
|------|----------|-------|
| `create_workstream(topic_id, title, ...)` | `slug?`; `owner?`; `description?`; `due_date?` | Creates workstream under a topic. Use `get_state_summary()` to find topic IDs. |
| `create_task(workstream_id, title, ...)` | `priority`: low/medium/high/critical; `assignee?`; `due_date?` | Creates task under a workstream. |
| `update_task_status(task_id, status, ...)` | `status`: todo/in_progress/blocked/done/cancelled; `blocking_reason` required when blocked | |
| `update_workstream_status(workstream_id, status)` | `status`: active/blocked/completed/archived | Thin shortcut — use `update_workstream` for full field control. |
| `update_workstream(workstream_id, ...)` | `title?`; `description?`; `owner?`; `due_date?`; `repo_goal_id?`; `status?` | Patch any subset of workstream fields. Pass empty string for `repo_goal_id` to clear the link. |

---

## Human Interventions

Tasks that agents cannot complete themselves are flagged with `needs_human=True`.
Use `list_human_interventions()` at session start to see Bernd's action items.

| Tool | Key Args | Notes |
|------|----------|-------|
| `flag_for_human(task_id, note)` | `task_id`: UUID; `note`: action description (required) | Sets needs_human=True + intervention_note. Emits progress event. |
| `clear_human_flag(task_id)` | `task_id`: UUID | Clears flag after human completes the action. Emits progress event. |
| `list_human_interventions(workstream_id?)` | optional workstream filter | Returns all tasks with needs_human=True. |

---

## Governance Tools

| Tool | Key Args | When to use |
|------|----------|-------------|
| `validate_repo_adr(repo_slug, domain_slug?)` | `repo_slug`: registered repo slug (e.g. `"the-custodian"`); `domain_slug?`: for orphan detection | Check a repo against ADR-001. Resolves the local path from the DB (uses this host's registered path). Detects missing workplans/ dir, invalid frontmatter, stale workstream ID references, and DB-only orphan workstreams. Always runs against the MCP server's copy — see Multi-Host section below. |

---

## Resources (URI-addressable, read-only)

| URI | Returns |
|-----|---------|
| `state://summary` | Full StateSummary JSON |
| `state://topics` | Active topics list |
| `state://workstreams/{topic_slug}` | Workstreams for a topic (by slug) |
| `state://decisions/blocking` | All pending decisions |
| `state://tasks/blocked` | All blocked tasks |

---

## Domain Management Tools (v0.5)

Domains are now first-class DB entities. Use `list_domains()` to discover available slugs.

| Tool | Key Args | Notes |
|------|----------|-------|
| `list_domains(status?)` | `status`: active/archived/all (default: active) | Discover all registered domains. |
| `create_domain(slug, name, description?)` | `slug`: lowercase_underscored; `name`: display name | Register a new project domain. |
| `rename_domain(slug, new_slug, new_name)` | all required | Renames domain and cascades to EP/TD string columns. |
| `archive_domain(slug)` | `slug` | Soft-delete; fails if active topics exist. |
| `list_domain_repos(domain_slug)` | `domain_slug` | List repos registered under a domain. |
| `register_repo(domain_slug, name, ...)` | `slug?`; `local_path?`; `remote_url?` | Register a git repo under a domain. |
| `update_repo_path(repo_slug, path, host?)` | `repo_slug`: e.g. `"marki-docx"`; `path`: absolute local path; `host`: defaults to current hostname | Register this machine's local path for a repo. Use when the same repo lives at different paths on different machines (e.g. `/home/worsch/…` vs `/home/tegwick/…`). The consistency checker prefers this over `local_path`. |

---

## Agent Inbox Tools

Inter-agent coordination via shared message board. Check inbox at session start;
send messages to coordinate across Claude instances.

Agent names: use the repo slug (e.g. `"marki-docx"`, `"railiance"`) or `"hub"` for the custodian agent.
Use `"broadcast"` as `to_agent` to send to all agents.

| Tool | Key Args | When to use |
|------|----------|-------------|
| `get_messages(to_agent?, from_agent?, unread_only?, limit?)` | `to_agent`: your agent name; `unread_only`: True recommended at session start | Check for pending coordination messages. |
| `send_message(from_agent, to_agent, subject, body, thread_id?)` | all except `thread_id` required | Send a coordination message to another agent (or broadcast). |
| `mark_message_read(message_id)` | `message_id`: UUID | Mark a message as read after acting on it. |
| `reply_to_message(message_id, from_agent, body)` | all required | Reply in-thread; marks original as read. |

Dashboard: `http://localhost:3000/inbox`

---

## Kaizen Agents

Specialized agent personas from `kaizen-agentic/agents/`. Each agent is a markdown
instruction set — load it and follow the instructions it contains.

| Tool | Key Args | When to use |
|------|----------|-------------|
| `list_kaizen_agents(category?)` | `category`: optional filter (testing/quality/process/infrastructure) | Discover all 17 available agent personas with name, description, category. |
| `get_kaizen_agent(name)` | `name`: e.g. `"tdd-workflow"`, `"code-refactoring"` | Load full agent instructions. Read and follow them. |

**Common agents:**

| Agent | Category | When to use |
|-------|----------|-------------|
| `tdd-workflow` | testing | Step-by-step TDD8 workflow for any feature |
| `code-refactoring` | quality | Code quality analysis and safe refactoring |
| `test-maintenance` | testing | Diagnose and fix failing tests |
| `requirements-engineering` | process | Prevent interface/mock mismatches upfront |
| `keepaTodofile` | process | Maintain TODO.md during work |
| `project-management` | process | Track status, determine next steps |
| `scope-analyst` | project-management | Analyze a repo and produce/improve SCOPE.md |
| `datamodel-optimization` | quality | Optimize dataclasses and data structures |

## Multi-Host & Remote Agent Usage

Three tools access the **local filesystem** on the MCP server machine:

| Tool | File-sys operation |
|------|-------------------|
| `validate_repo_adr` | Runs `validate_repo_adr.py` against the server's repo checkout |
| `check_repo_consistency` | Runs `consistency_check.py` against the server's repo checkout |
| `ingest_sbom_tool` | Runs `ingest_sbom.py` against the server's lockfiles |

**Design boundary:** these tools always execute on the machine where the MCP server
runs (`bnt-lap001`), against the path registered for that host. A remote agent
calling them gets results from the server's checkout — not from its own working copy.

### Implications for remote agents (e.g. workers on COULOMBCORE)

- **Ahead of server on a branch?** Results will be based on the server's (older) copy.
  Sync first: push your branch and pull it on the server, or accept the gap.
- **Pure-API tools** (`get_state_summary`, `create_task`, `add_progress_event`, etc.)
  work correctly from any host — they query the DB, not the filesystem.

### Running file-sys scripts locally from a remote host

```bash
# From COULOMBCORE (tunnel maps remote :18000 → bnt-lap001 :8000):
python scripts/consistency_check.py --repo the-custodian --api-base http://127.0.0.1:18000
python scripts/validate_repo_adr.py /home/tegwick/the-custodian --api-base http://127.0.0.1:18000
```

### Registering a new host path

```bash
# Via MCP tool:
update_repo_path("marki-docx", "/home/tegwick/marki-docx")   # defaults to current hostname

# Via Makefile (on the machine where the path lives):
make register-path REPO=marki-docx PATH=/home/tegwick/marki-docx

# Via API directly:
curl -X POST http://127.0.0.1:8000/repos/marki-docx/paths/ \
  -H "Content-Type: application/json" \
  -d '{"host": "your-hostname", "path": "/home/you/marki-docx"}'
```

## Domain Slugs

Run `list_domains()` to get the live list. Default 6: `custodian` · `railiance` · `markitect` · `coulomb_social` · `personhood` · `foerster_capabilities`

---

## Common Patterns

```python
# Session start:
get_state_summary()

# Decision resolved in the hub UI or via tool:
resolve_decision(decision_id="<uuid>", rationale="...", decided_by="Bernd")

# Session end:
add_progress_event(
    summary="...",
    event_type="note",          # or milestone / insight / blocker
    topic_id="<uuid>",
    workstream_id="<uuid>",     # optional
    detail={"key": "value"},    # optional
)

# First Session Protocol only — bootstrap a new project:
create_workstream(topic_id="<uuid>", title="My Workstream", owner="me")
create_task(workstream_id="<uuid>", title="Do the thing", priority="high")
```
