SAM Infrastructure Research and Design Prompt

Mission

Research 5 existing agent coordination systems to understand their meta-messaging, artifact storage, and git worktree awareness patterns. Use findings to design a comprehensive infrastructure layer for the Stateless Agent Methodology (SAM).

Background Context

What is SAM?: The Stateless Agent Methodology treats Claude as a stateless function operating in 7 stages:

1. Discovery & Interview
2. Context Gathering
3. Research & Learning
4. Design & Architecture
5. Planning
6. Implementation & Validation
7. Delivery

Current Gap: SAM currently lacks infrastructure for:

• Meta-messaging (agent-to-agent async communication via message queues)
• Task-agent association (YAML config for agent selection + skill loading per task/stage)
• Structured artifact storage (designs, specs, plans, tasks, checkpoints)
• MCP server interface to the infrastructure
• Git worktree awareness (pull, rebase, read state from commits)

Reference Document: Read ./methodology_development/stateless-agent-methodology.md for complete SAM specification (relative to repo root).

Target Repositories for Research

Research these 5 systems to understand their infrastructure patterns:

1. ~/repos/gastown - Emphasize git worktree awareness patterns (user noted this has good example)
2. ~/repos/octocode-mcp - MCP server integration patterns
3. ~/repos/get-shit-done - Task and checkpoint management
4. ~/repos/cc-sessions - Session state and continuity
5. ~/repos/BMAD-METHOD - Multi-agent coordination (21+ agents)

Research Focus Areas

For each repository, identify:

1. Meta-Messaging Patterns

Definition: Information about the process or tasks in the process - NOT code changes to the project.

Questions to answer:

• How do agents communicate asynchronously?
• What message queue systems are used (if any)?
• What types of meta-messages are sent between agents?
• How are messages structured (schema/format)?
• How do agents read from their message queues?
• Are messages persistent or ephemeral?

Example meta-messages to look for:

• "Task X completed, Task Y can now start"
• "Context gathering found 15 relevant files"
• "Design validation failed: missing constraint Y"
• "Agent A blocked on user clarification"

2. Artifact Types and Lifecycle

Definition: Structured documents that capture process state, decisions, plans, and progress.

Questions to answer:

• What artifact types are created? (designs, specs, plans, tasks, checkpoints, etc.)
• What is the lifecycle of each artifact? (created → updated → validated → archived)
• What information does each artifact contain?
• How are artifacts referenced between stages/agents?
• Are artifacts versioned? How?

Example artifacts to identify:

• Design documents (architecture decisions, constraints)
• Context documents (gathered information, research findings)
• Specification documents (requirements, acceptance criteria)
• Plan documents (task breakdown, dependencies)
• Task documents (individual work units with status)
• Checkpoint documents (progress snapshots, state recovery points)

3. Storage Patterns

Questions to answer:

• Where are artifacts stored? (filesystem, sqlite3, cloud db, git issues/milestones)
• What directory structure or schema is used?
• How are artifacts organized by project/session/stage?
• How are artifacts retrieved by agents?
• What indexing or search capabilities exist?

Look for:

• .planning/ or similar directories
• Database schemas (sqlite/postgres)
• Git integration (issues, milestones, projects)
• Naming conventions for files/records

4. Agent Coordination Patterns

Questions to answer:

• How are agents selected for tasks?
• How is agent-task association configured? (hardcoded, YAML, dynamic)
• What skills/capabilities must agents load per task?
• How do agents signal completion or blocking?
• How are dependencies between agents handled?

Look for:

• Configuration files (YAML, JSON) mapping tasks to agents
• Agent capability declarations
• Task dependency specifications
• Completion signaling mechanisms

5. Git Worktree Awareness (Priority: Gastown)

Questions to answer:

• How does the system detect git state changes?
• When does pull/rebase happen in the workflow?
• How are commit messages used for state recovery?
• How does the system handle merge conflicts?
• How does the system read recent changes from git history?
• What git operations are first-class in the workflow?

Look for (especially in gastown):

• Git operation automation
• Commit message parsing for state
• Rebase handling
• Working tree status detection
• Change detection between sessions

- Task-agent association format
- Skill loading specification
- Stage-level configuration
- Example configurations

### Component 3: Artifact Storage System

- Storage backend options (filesystem, sqlite, supabase, git)
- Directory structure or database schema
- Retrieval API

### Component 4: MCP Server Interface

Research Methodology

Follow this process:

1. For each repository:

   • Start by reading README.md or main documentation
   • Use Glob to find configuration files (.yaml,.json, *.toml)
   • Use Glob to find artifact storage directories (.planning/, .artifacts/, etc.)
   • Use Grep to search for message queue patterns, agent coordination keywords
   • Read key implementation files that handle messaging, artifacts, git operations
   • Document findings with file paths and line numbers for citations

2. Evidence-based analysis:

   • Cite specific files and line numbers for all claims
   • If a pattern is not explicitly found, mark as "NOT_OBSERVED" rather than assuming
   • Distinguish between documented patterns and implemented patterns
   • Note version/date of repository when accessed

3. Synthesis:

   • Create comparison tables showing patterns across all 5 systems
   • Identify common patterns (convergence) and unique approaches (divergence)
   • Recommend patterns for SAM based on evidence, not assumptions

Tools Available

• Read(file_path) - Read any file in the repositories
• Glob(pattern, path) - Find files matching patterns
• Grep(pattern, path, output_mode) - Search file contents
• Bash - Run git commands or directory listing if needed

Success Criteria

You have completed this task when:

• All 5 repositories have been researched with evidence citations
• Meta-message types documented for each system with examples
• Artifact types documented for each system with schemas/examples
• Storage patterns documented with directory structures or DB schemas
• Git worktree awareness patterns documented (especially gastown)
• Comparison tables created showing patterns across systems
• sam-infrastructure-research.md created with complete findings
• sam-infrastructure-layer.md created with design specification
• All claims cited with file paths and line numbers
• Recommendations grounded in observed patterns, not assumptions

Starting Point

Begin with gastown repository since user emphasized it has good git worktree awareness example:

cd ~/repos/gastown
Read README.md or similar entry point
Glob **/*.{yaml,json,toml} to find config files
Grep for git-related keywords (rebase, commit, worktree, etc.)

Context Files to Read First

Before starting research, read these files to understand SAM:

1. ./methodology_development/stateless-agent-methodology.md - Complete SAM specification
2. ./methodology_development/sam-framework-generator.md - Meta-SAM concept (using SAM to generate SAM implementations)

Notes

• Focus on meta-messages (information about process/tasks), not code change messages
• Git worktree awareness is critical - gastown is the priority example
• Evidence-based research only - cite all findings with file paths and line numbers
• If uncertain, mark "UNVERIFIED" and explain the gap rather than assuming
