The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill facilitates the installation of the cosmos-pp-cli and cosmos-pp-mcp tools using npx -y @mvanhorn/printing-press-library and go install github.com/mvanhorn/printing-press-library/.... These resources are hosted within the vendor's official package namespace and repository structure.
[COMMAND_EXECUTION]: The agent is instructed to use the Read Bash tool to execute a wide variety of shell commands to interact with the Cosmos API, manage local configuration, and perform data operations.
[DYNAMIC_EXECUTION]: The skill utilizes a self-capturing learning loop where the cosmos-pp-cli recall command provides 'playbooks' and 'trial commands' that the agent is expected to execute. This involves dynamic command construction from tool-provided templates with slot substitutions.
[DATA_EXFILTRATION]: Supports a --deliver webhook:<url> flag, allowing the agent to POST command results, including exported collection data, to arbitrary external URLs.
[INDIRECT_PROMPT_INJECTION]: The skill's 'Automatic learning' and 'Discovery' features ingest data from the Cosmos GraphQL API, which is then used to generate future command suggestions and playbooks for the agent.
Ingestion points: cosmos-pp-cli recall, collection coverage, and element trail output.
Boundary markers: The CLI uses a structured JSON response envelope to separate tool metadata from data results.
Capability inventory: The agent has shell execution capabilities via the Read Bash tool.
Sanitization: The CLI documentation notes that it attempts to strip PII and uses structural mapping, though the agent remains responsible for validating trial commands before execution.
