Run scope-realism analysis and premortem on an approved-or-pending plan. Outputs a complexity score, a quantified likelihood that ≥1 premortem scenario fires, and a ranked list of likely failure scenarios seeded by /g-patterns history. Plan-time gate, never blocks — surfaces risk for human judgment.

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

**Announce:** "Using g-forecast to analyse scope realism and run a premortem."

A forward-looking risk pass on a plan before it executes. Output is advisory — never blocks approval. This skill's `scripts/` and `references/` paths are relative to its own directory; run every script with Bash from the project root.

## Step 1 — Identify the target plan

Run `scripts/find-plan.sh "$ARGUMENTS"`. Its case order is contractual: **1** pending-handoff `g-docs/plans/.pending-forecast.md` (written by `/g-plan` Step 3a), **2** developer-passed slug or path, **3** most-recent `g-docs/plans/*.md` with a `pending` wave. On `EXIT: no-plan`, print exactly:
```
✗ No plan to forecast. Run /g-plan first, or pass a plan slug as argument.
```
and stop. Record the plan-slug (`SLUG:`; on case 1, derive it from the plan's title) — Step 8 uses it for the output filename.

## Step 2 — Score complexity

Load the normative measurement thresholds in `references/scoring-notes.md` (its `## Step 2` section — always, before scoring), then compute a 0–10 score from the plan:

| Signal | Weight |
|--------|--------|
| File count touched | 0–3 |
| Wave count | 0–2 |
| Layer-boundary crossings | 0–2 |

How to install

The exact contents, by fingerprint
mdr add onlygian/g-forge/g-forecast@sha256:da2d93123fb79fa9

The line at the top of this page pins the label git:20260902.43671e4, 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.
