Inspect or modify Letta Code's own memory, model, context window, system prompt, compaction, permissions, toolsets, mods, skills, channels, schedules, agent secrets, and local runtime settings. Use when the user asks how this agent or conversation is configured, asks about account usage, remaining credits, or model quota, asks you to change how you behave or how the harness runs you, or renames you.
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
# Self-Configuration
Use this skill when the user asks you to change yourself or the Letta Code runtime around you.
The important part is choosing the right layer. Do not smear a preference into deterministic config, and do not bury a deterministic safety rule in prose memory.
## First choose the layer
| Layer | Use it for | How to change it |
| --- | --- | --- |
| Memory and identity | Facts worth retaining, style preferences, persona changes, project knowledge, reusable skills | Edit `$MEMORY_DIR` files and sync the memory repo |
| Server agent fields | Agent default model (only on explicit request), context limit, system prompt, compaction, agent name, description | Patch `/v1/agents/{agent_id}` |
| Server conversation fields | Model/context changes for the current conversation (the normal target) | Patch `/v1/conversations/{conversation_id}` |
| Local settings | Permissions, environment variables, UI/runtime preferences, pinned agents, toolset overrides, reflection cadence | Edit `$LETTA_CONFIG_DIR/settings.json` when configured (otherwise `~/.letta/settings.json`), `./.letta/settings.json`, or `./.letta/settings.local.json` |

How to install
mdr add letta-ai/letta-code/self-configuration@sha256:25ba05cbbf34fd6eThe line at the top of this page pins the label git:20261028.a8f8e4b, 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.
