+name: refresh-model-catalog
+description: Use when adding or removing Command Code models, refreshing the model catalog snapshot (image, reasoning, effort, output-limit metadata), updating display pricing, or refreshing test fixtures in pi-commandcode-provider.
+---
+
+# Refresh Model Catalog
+
+Use this skill whenever the Command Code model catalog changes: new or retired models, changed reasoning efforts, output limits, or pricing. All commands run from the repository root and work on Windows and Linux.
+
+## Core rules
+
+- Do not commit, tag, push, or publish unless the user explicitly asks in the current conversation.
+- Pricing is manually reviewed: temporary promotions and long-context tiers require explicit review of the official pricing page. Never copy prices blindly from the API.
+- Keep the change focused: one refresh per PR, no unrelated refactors.
+- Follow [CONTRIBUTING.md](../../../CONTRIBUTING.md) for commit message rules.
+
+## Workflow
+
+### 1. Detect drift
+
+```sh
+npm run check:commandcode-catalog
+```
+
+This compares the repository snapshot against the latest published `command-code` npm package and reports added/removed models, changed efforts, and version drift. Use the report to scope the work.
+
+### 2. Sync static model metadata
+
+```sh
+npm run sync:commandcode-catalog
+```
+
+Regenerates `src/commandcode-catalog.ts` and bumps the documented CLI version in `README.md`. Review the diff; the catalog also lists reasoning models without selectable efforts.
+
+### 3. Update display pricing (manual review)
+
+Fetch <https://commandcode.ai/docs/resources/pricing-limits> and compare against `src/pricing.ts`:
+
+- Add entries for new models and remove entries for retired models. Missing models silently display zero cost, so `MODEL_COSTS` must cover the full catalog.
+- The pricing page's "Cache Read"/"Cache Write" columns map to `cacheRead`/`cacheWrite`; a "—" column means `0`.
+- Update `PRICING_LAST_VERIFIED` to today's date.
+- Add or update `TEMPORARY_PRICING` entries for promotions with an end date, so tests fail when they expire.
+
+### 4. Refresh the test fixtures
+
+```sh
+node .agents/skills/refresh-model-catalog/scripts/refresh-model-ids.mjs
+npx tsx .agents/skills/refresh-model-catalog/scripts/sync-pricing-fixture.ts
+```
+
+The first script snapshots the live model-id list into `tests/fixtures/commandcode-model-ids.json`; the second regenerates `tests/fixtures/commandcode-pricing.json` from `MODEL_COSTS`. The pricing test fails until `MODEL_COSTS` matches the catalog snapshot exactly.
+
+### 5. Update test expectations
+
+Adjust the model-specific assertions that the refresh invalidated, typically in:
+
+- `tests/test-pricing.ts`: fixture date assertions, the `freeModels` set, and per-model rate assertions.
+- `tests/test-models.ts`: image/reasoning/effort/output-limit assertions and catalog entry counts.
+
+Do not weaken assertions to make them pass; update them to the verified upstream values.
+
+### 6. Validate
+
+```sh
+npm run test:models
+npm run test:pricing
+npm run typecheck
+npm run format:check
+git diff --check
+```
+
+Run the full `npm test` before reporting the work as done when the environment allows it.
+
+### 7. Document
+
+Add entries to the `Unreleased` section of `CHANGELOG.md` covering new/retired models, effort changes, and pricing refreshes.
