The thinking a small model skips, as steps it must write down: before the first edit, an assumptions table and a three-flaw check on the brief (contradiction, missing fact, impossible ask), each flaw checked by a command; when stuck, one observation, one hypothesis, one falsifying command; and a THINK report line. Pushback is a written line in the report, never a question that stops the work. Slice 2 of xeno-skills #355.
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
# Think first (`qwen38-think`) **Before the first edit, write the two tables below into your answer. Then build. End with the THINK line.** Doing the work first and the tables after is a fail of this skill. ## 1. Assumptions table Everything the brief leaves open that changes what you would build. Take the assumption; do not ask. | open in the brief | the assumption you take | why this one | |---|---|---| | e.g. "ordering when quantities tie" | by sku, ascending | the brief orders by quantity; a stable secondary key is the usual reading | Zero rows is allowed only if you write "none — the brief fixes every choice" and can point to where. ## 2. Three-flaw check — each one checked, not guessed | flaw type | what you looked for | the command you ran | found? | |---|---|---|---| | **contradiction** — two sentences of the brief cannot both hold | e.g. "return None" and "return the remaining quantity" | `grep -n "return" <file>` / re-read the brief | yes / no | | **missing fact** — a file, function, endpoint or value the brief names does not exist | e.g. `inventory/report.py` | `ls <path>` · `grep -rn "<name>" .` | yes / no | …

How to install
mdr add xenodeve/xeno-skills/qwen38-think@sha256:80eccdff8a77d3d0The line at the top of this page pins the label git:20261006.5f9ecd1, 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.
