The Agent Skills Directory

[COMMAND_EXECUTION]: The skill utilizes the openspec CLI tool to perform project-level actions. These include initializing the environment, checking change status, and validating artifact formats.
[EXTERNAL_DOWNLOADS]: The skill references the installation and execution of the @fission-ai/openspec package via npx or pnpm. This is the primary tool for the specification-driven workflow and is fetched from the official NPM registry.
[INDIRECT_PROMPT_INJECTION]: The skill is designed to process and act upon content within project-specific specification and design documents, which could potentially contain untrusted instructions if files are manipulated externally.
Ingestion points: Files located in openspec/specs/ and openspec/changes/ including proposals, technical designs, and task lists.
Boundary markers: Uses mandatory Markdown structures and keywords (MUST, SHALL, GIVEN, WHEN, THEN) to delimit requirements. Employs openspec validate --strict to enforce these boundaries.
Capability inventory: The agent has the capability to modify project files and execute local CLI commands based on the content of these documents.
Sanitization: Validates the schema and structure of artifacts before implementation, reducing the risk of accidental execution of malformed instructions.
