The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: References the celticht32/MCP-Couchbase repository for cluster interaction. This is a vendor-owned resource essential for the skill's functionality and is documented neutrally.
[DATA_EXFILTRATION]: Utilizes tools that read system catalogs (system:completed_requests) and sample document data (cb_get_schema_for_collection). These operations are necessary for query performance diagnosis and schema discovery.
[COMMAND_EXECUTION]: Provides instructions for environment setup, including running the MCP server with uv run and configuring read-only modes via environment variables.
[PROMPT_INJECTION]: The skill processes untrusted user input in the form of SQL queries and EXPLAIN plans, creating an inherent surface for indirect prompt injection.
Ingestion points: User-provided SQL statements and tool outputs from cb_explain_query (SKILL.md, references/diagnostic-workflow.md).
Boundary markers: Absent; the agent is instructed to process the query text directly.
Capability inventory: Index creation (admin_index_create), cluster queries (cb_query), and local server execution (uv run) (references/diagnostic-workflow.md).
Sanitization: Not explicitly defined for the agent's context; the documentation focuses on preventing traditional SQL injection rather than prompt injection.
