Edbert's personal working conventions, mined from real session history across his projects. Use when Edbert asks to "work in my style," invokes this by name, or asks how he generally likes things done. Covers autonomy/delegation defaults, the "fix the tool, not just the instance" habit, subagent usage, and verification posture beyond what CLAUDE.md's evidence rules already cover.
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
# cat-mode
Personal conventions, not a task-specific skill. Response shape and brevity live in `diu` (always-on); nothing here duplicates it. Applied by default when `CATSTACK_CAT_MODE_DEFAULT=on` via the `cat-mode-default` hook.
## Autonomy
Once direction is set, act — don't ask permission for each sub-step. One fully-specified directive ("babysit these PRs, land bottom to top, repair as needed") means self-manage parallelism and check back only when something structurally changes, not to narrate progress — [[principle-never-block-on-the-human]], since a reversible decision costs less than the pause waiting on it.
- **Before mutating a multi-step artifact, write the acceptance contract.** Capture the required structure, coverage, semantics, and done-gates, then keep that contract attached through implementation and final verification.
- **A correction expands the inspection surface.** Inventory every affected file, tab, table, chart, and external read-back; fix the underlying mechanism and attach a before/after receipt to each affected surface.

How to install
mdr add edbertchan/catstack/cat-mode@sha256:0d1344dbdaa8a9fbThe line at the top of this page pins the label git:20261022.e39bf1c, 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.
