Project Memory Skill

This skill acts as the system's "hippocampus," responsible for storing, retrieving, and updating long-term project contextual information.

Purpose

To provide a single source of truth about project status, technical decisions, and global configurations, accessible to all authorized agents.

Capabilities

1. read_context

Reads information from the global context.

• Input:
  • key (optional): The specific key to read (e.g., tech_stack.languages). If omitted, returns the entire context.
• Behavior:
  1. Loads memory-store/global_context.yaml.
  2. If key is provided, navigates the object to find the value.
  3. Returns the value or the entire object.

2. update_context

Updates or inserts information into the global context.

• Input:
  • key: The key to update (e.g., active_phase.current). Supports dot notation for nesting.
  • value: The new value.
• Behavior:
  1. Loads memory-store/global_context.yaml.
  2. Updates the value at the specified path.
  3. Saves the file.
  4. Returns confirmation.

3. log_decision

Logs an important decision or milestone in the project log.

• Input:
  • title: Title of the decision.
  • description: Brief description.
  • status: Status (e.g., PROPOSED, ACCEPTED, DEPRECATED).
  • adr_link (optional): Link to the corresponding ADR file.
• Behavior:
  1. Loads memory-store/global_context.yaml.
  2. Adds an entry to the decisions_log list with the current timestamp.
  3. Saves the file.

Usage (A2A)

Tech Stack Query

request = {
    "type": "QUERY",
    "target": "project-memory",
    "payload": {
        "action": "read_context",
        "key": "tech_stack"
    }
}

Phase Update

request = {
    "type": "TASK",
    "target": "project-memory",
    "payload": {
        "action": "update_context",
        "key": "active_phase.status",
        "value": "Completed"
    }
}
