dr-drive-harness SKILL.md skillA
dr-drive-harness from ahepi/deepreason is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add ahepi/deepreason/dr-drive-harness@git:20260903.d23eb93Pins git:20260903.d23eb93 in mdr.lock. Pin the fingerprint instead.

The driving manual for DeepReason - how to run the harness properly (session preflight, the public CLI lifecycle, live-run ladders) and where to look before modifying anything or when diagnosing a problem. An index over the owning authorities (CLAUDE.md, docs/map, the workflow skills), not a replacement for them. Load at the start of any session that will run, modify, or diagnose the harness, especially a first session in this repo.
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
# Drive the harness
You are operating a Popperian reasoning harness whose entire epistemology
rests on one rule: **the typed record is the only admissible evidence**.
`log.jsonl`, `objects/`, `progress.jsonl`, `run-status.json`,
`REPLAY_VALIDATION.json`, `verify_root` — those are evidence. Model prose,
including yours, is not. Every section below is an index: it tells you the
load-bearing command and WHERE the full authority lives, so you never
operate from a half-remembered copy.
## 1. Session preflight (before anything else)
The cloud container rolls back silently — stale checkout, dead processes,
deleted gitignored files. CLAUDE.md's "Environment" section is the
authority; the sequence is:
git log --oneline -1 # stale head? resync:
git fetch origin <branch> && git checkout -B <branch> origin/<branch>
python -c "import deepreason" || pip install -e . --break-system-packages -q
ls experiments/*/env 2>/dev/null # gitignored credentials survive?
**No live launch without a green soak on the launch config**: run
`python -u scripts/cycle_soak.py --case <case>` before any ladder launch.

How to install
mdr add ahepi/deepreason/dr-drive-harness@sha256:94c3292b45e492c8The line at the top of this page pins the label git:20260903.d23eb93, 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.
