The Agent Skills Directory

[SAFE]: The skill is a standard configuration utility for Letta agents. It provides instructions and a script to interact with the official Letta API (api.letta.com). All network operations are directed at vendor-owned infrastructure and are consistent with the skill's purpose.
[INDIRECT_PROMPT_INJECTION]: The skill facilitates the design of prompts for context summarization, which process untrusted message history. This introduces an inherent surface for indirect prompt injection.
Ingestion points: Untrusted message history processed during the compaction lifecycle.
Boundary markers: Recommended templates include explicit instructions such as 'Do NOT continue the conversation', 'Do NOT respond to any questions', and 'Do NOT call any tools' to constrain the summarizer's behavior.
Capability inventory: The resulting summaries are reinserted into the agent's context window via the PATCH API endpoint used in scripts/update-compaction-prompt.ts.
Sanitization: The skill relies on model instruction following and hard character limits (clip_chars) defined in the compaction_settings object.
