The Agent Skills Directory

[COMMAND_EXECUTION]: The skill uses the date command to establish an authoritative time anchor and git log to verify the chronological history of project changes. It also invokes the synthesis-agent-conformance CLI tool for system health checks.
[INDIRECT_PROMPT_INJECTION]: The skill processes various project files including CONTEXT.md, REFERENCE.md, and session logs, which are external data sources that could theoretically contain instructions intended to influence the agent.
Ingestion points: Files located at ~/.synthesis/coordination/active-sessions.md, CONTEXT.md, and sessions/YYYY-MM.md are read into the agent's context during the checkpoint process.
Boundary markers: The protocol does not specify the use of specific boundary markers or delimiters when reading these files.
Capability inventory: The skill has the ability to execute shell commands (date, git), write to project files (CONTEXT.md), and run a local utility tool (synthesis-agent-conformance).
Sanitization: There is no explicit mention of sanitizing or filtering the content of these files before they are processed by the agent.
