RFC 0002: Runbook Action Lookup

Status	Implemented
Date	2026-01-24
Source Spike	runbook-driven-actions

---

Summary

No way to discover and follow runbooks when performing repo actions. Claude guesses instead of following documented procedures for docker builds, deploys, releases, etc.

Proposal

1. Action Tags in Runbooks

Add actions field to runbook frontmatter:

# Runbook: Docker Build

| | |
|---|---|
| **Status** | Active |
| **Actions** | docker build, build image, container build |

Store actions in SQLite metadata table for fast lookup.

2. New Tool: blue_runbook_lookup

blue_runbook_lookup action="docker build"

Returns structured response:

{
  "found": true,
  "runbook": {
    "title": "Docker Build",
    "file": ".blue/docs/runbooks/docker-build.md",
    "actions": ["docker build", "build image", "container build"],
    "operations": [
      {
        "name": "Build Production Image",
        "steps": ["...", "..."],
        "verification": "docker images | grep myapp",
        "rollback": "docker rmi myapp:latest"
      }
    ]
  },
  "hint": "Follow the steps above. Use verification to confirm success."
}

If no match: { "found": false, "hint": "No runbook found. Proceed with caution." }

3. New Tool: blue_runbook_actions

List all registered actions:

blue_runbook_actions

Returns:

{
  "actions": [
    { "action": "docker build", "runbook": "Docker Build" },
    { "action": "deploy staging", "runbook": "Deployment" },
    { "action": "run tests", "runbook": "Testing" }
  ]
}

4. Matching Algorithm

Word-based matching with priority:

1. Exact match - "docker build" matches "docker build" (100%)
2. All words match - "docker" matches "docker build" (90%)
3. Partial words - "build" matches "docker build" (80%)

If multiple runbooks match, return highest priority. Ties broken by most specific (more words in action).

5. Schema

-- In metadata table
INSERT INTO metadata (document_id, key, value)
VALUES (runbook_id, 'action', 'docker build');

-- Multiple actions = multiple rows
INSERT INTO metadata (document_id, key, value)
VALUES (runbook_id, 'action', 'build image');

6. Update blue_runbook_create

blue_runbook_create title="Docker Build" actions=["docker build", "build image"]

• Accept actions array parameter
• Store each action in metadata table
• Include in generated markdown

7. CLAUDE.md Guidance

Document the pattern for repos:

## Runbooks

Before executing build, deploy, or release operations:

1. Check for runbook: `blue_runbook_lookup action="docker build"`
2. If found, follow the documented steps
3. Use verification commands to confirm success
4. If something fails, check rollback procedures

Available actions: `blue_runbook_actions`

Security Note

Runbooks should never contain actual credentials or secrets. Use placeholders:

**Steps**:
1. Export credentials: `export API_KEY=$YOUR_API_KEY`
2. Run deploy: `./deploy.sh`

Not:

**Steps**:
1. Run deploy: `API_KEY=abc123 ./deploy.sh`  # WRONG!

Example Runbook

# Runbook: Docker Build

| | |
|---|---|
| **Status** | Active |
| **Actions** | docker build, build image, container build |
| **Owner** | Platform Team |

## Overview

Build and tag Docker images for the application.

## Prerequisites

- [ ] Docker installed and running
- [ ] Access to container registry
- [ ] `.env` file configured

## Common Operations

### Operation: Build Production Image

**When to use**: Preparing for deployment

**Steps**:
1. Ensure on correct branch: `git branch --show-current`
2. Pull latest: `git pull origin main`
3. Build image: `docker build -t myapp:$(git rev-parse --short HEAD) .`
4. Tag as latest: `docker tag myapp:$(git rev-parse --short HEAD) myapp:latest`

**Verification**:
```bash
docker images | grep myapp
docker run --rm myapp:latest --version

Rollback:

docker rmi myapp:latest
docker tag myapp:previous myapp:latest

Troubleshooting

Symptom: Build fails with "no space left"

Resolution:

1. docker system prune -a
2. Retry build

## Implementation

1. Add `actions` parameter to `blue_runbook_create`
2. Store actions in metadata table
3. Implement `blue_runbook_lookup` with matching algorithm
4. Implement `blue_runbook_actions` for discovery
5. Parse runbook markdown to extract operations
6. Update runbook markdown generation

## Test Plan

- [ ] Create runbook with actions tags
- [ ] Lookup by exact action match
- [ ] Lookup by partial match (word subset)
- [ ] No match returns gracefully
- [ ] Multiple runbooks - highest priority wins
- [ ] List all actions works
- [ ] Actions stored in SQLite metadata
- [ ] Operations parsed from markdown correctly
- [ ] Malformed runbook returns partial data gracefully
