Check a Trade Story both for structure and syntax, and for whether its trade setup can be resolved without guessing.
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
# Verify a Trade Story
Follow `${CLAUDE_SKILL_DIR}/../../story-skills.md` and
`${CLAUDE_SKILL_DIR}/../../reading-stories.md`.
## Step 1 — mechanical checks
Print `Checking grammar`, then run:
```
node "${CLAUDE_SKILL_DIR}/../../../dsl/src/verify.js" <path>
```
Always run it. Step 1 errors come from `verify.js` and nowhere else — never work
one out by reading the story yourself, however obvious it looks.
Report every error in `errors`. If there is at least one, stop — do not start
step 2. If there are none, print `✅ Checked grammar.` and go on to step 2. That
is the only success line this step has: the report's belongs to the whole skill,
and printing it here claims the story passed before it has been read.
`hints` are not errors. Print a hint only when its line falls inside a clause an
error names: verbatim, as a fourth line under that error, prefixed `Hint: `.
## Step 2 — trade setup
Only if step 1 returned no errors. Print `Checking trade setup details`, then
check **every** merged clause in `merged` against **What makes a story unusable**
in `${CLAUDE_SKILL_DIR}/../../../dsl/domain-rules.md`, reporting each as

How to install
mdr add mafftopia/trade-stories/verify-story@sha256:a74d915f9e091ea4The line at the top of this page pins the label git:20260905.b06005f, 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.
