Configures Letta agents' own runtime behavior, including model, context window, system prompt, reasoning, conversation overrides, compaction settings, and compaction prompts. Use when an agent or user asks to self-modify, tune summarization/compaction, change identity/system instructions, adjust model settings, or test conversation-scoped overrides.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Letta self-configuration
Use the Letta API when an agent needs to change its own persistent defaults or the current conversation's temporary runtime settings.
## Safety rule
Ask before changing persistent agent defaults unless the user explicitly requested the change. Persistent changes include agent model, system prompt, context window, model settings, and compaction settings. Prefer conversation-scoped changes for experiments.
## Decision tree
- Need a temporary model/context experiment? Patch the **current conversation**.
- Need persistent model, system prompt, or compaction behavior? Patch the **agent**.
- Need better summaries after context eviction? Use the **Compaction settings** section and prompt patterns.
- Need provider keys, BYOK setup, or server deployment env vars? Use the broader Letta configuration/API skills instead.
- Need to design a new agent from scratch? Use the agent-development skill.
## Environment
```bash
BASE_URL="${LETTA_BASE_URL:-https://api.letta.com}"
: "${LETTA_API_KEY:?Set LETTA_API_KEY}"
: "${AGENT_ID:?Set AGENT_ID}"
```
Use `AGENT_ID` for yourself. Use `CONVERSATION_ID` for the current thread when it is available.

How to install
mdr add letta-ai/skills/self-configuration@sha256:7e2dcaa0c838c61eThe line at the top of this page pins the label git:20260618.9da3d97, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
