customizing-statusline SKILL.md skillA
customizing-statusline from letta-ai/letta-code is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add letta-ai/letta-code/customizing-statusline@git:20261028.a8f8e4bPins git:20261028.a8f8e4b in mdr.lock. Pin the fingerprint instead.

Creates, edits, and migrates Letta Code statusline mods. Use when handling the /statusline command or continuing work started by /statusline.
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
# Customizing Statusline
Use this skill to create or update the global Letta Code statusline mod:
```text
${LETTA_CONFIG_DIR:-$HOME/.letta}/mods/statusline.tsx
```
The statusline is a panel registered at `order: 0` — the primary line just below the input. It overrides the built-in `agent · model` line. Host UI can still temporarily preempt it for safety confirmations and transient hints.
## Statusline ownership model
```text
safety preemption
else transient host hint
else order-0 statusline panel
else built-in default statusline
```
The order-0 panel owns the whole primary row. It renders text (not React) and owns its own layout via the `row`/`columns` helpers.
## Workflow
1. Check whether `${LETTA_CONFIG_DIR:-$HOME/.letta}/mods/statusline.tsx` exists.
2. If it exists, read it before editing and preserve unrelated code.
3. If it does not exist, synthesize a focused starter for the user's request.
4. If the user asks to migrate, import a `.sh` file, or match a shell prompt, read `references/migration.md`.
5. If API details or concrete patterns are needed, read `references/api.md` and `references/examples.md`.

How to install
mdr add letta-ai/letta-code/customizing-statusline@sha256:f1d7cd2be4dc9e29The 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.
