+- **Workflow for every change** (this section overrides any other instruction an agent carries,
+  such as a parent repository's CLAUDE.md or a task runner's "run tests and linters" step):
+  1. Work in your own worktree on a branch, with your own `CARGO_TARGET_DIR`. While you work:
+     `cargo check` and the tests of the crates you touch (`cargo test -p <crate>`). Commit after
+     each working step (a layer that compiles with its tests passing), not one big commit per PR.
+  2. When the change is done: review it once with `/simplify`, then `cargo fmt --all` and
+     `cargo clippy -p <crate> --all-targets -- -D warnings` for each crate you touched, once.
+     Regenerate what your change affects: `docs/features.md` when commands change
+     (`cargo run -p modelcraft-cli -- features > docs/features.md`), `docs/oracle.md` when
+     oracle cases or solver numerics change (`cargo xtask oracle`).
+  3. Rebase onto the latest `origin/main` (never merge `main` into a branch), rerun the tests of
+     the touched crates, push, open the PR and merge it yourself:
+     `gh pr merge <N> --squash --delete-branch`, run as its own command.
+  4. Never run the full gate locally: no `cargo xtask ci`, no `cargo clippy --workspace`, no
+     `cargo xtask wasm` or `oracle` unless step 2 calls for it. Never watch CI. GitHub CI runs
+     `cargo xtask ci` (fmt, assets, licences, layers, clippy -D warnings, tests, wasm), the
+     oracle, the heavy tests and the advisories once per merge on `main`; the coordinator
+     watches it and sends a failure back to the change that caused it, which is fixed forward
+     at once.
+- **Keep the main gate fast** (under ~3 minutes on CI). A test that takes more than a few seconds
   (convergence studies, the whole corpus, cross-checks between solvers) is
   `#[ignore = "heavy: cargo xtask test --heavy (CI heavy job)"]`, with a fast representative
-  test left in the PR gate. The `heavy` CI job runs `cargo xtask test --heavy` (every ignored
-  test, benchmarks included, and the doc tests) on pushes to `main`, nightly and on demand
-  (`gh workflow run CI --ref <branch>`). Hostile-input tests run commands on sessions with small

+  test, benchmarks included, and the doc tests) on every merge to `main`, nightly and on

   work caps (`Session::limits`) so refusals are instant; never lower the production caps for a
   test.
-- **Publishing**: `origin` is github.com/jyviko/modelcraft. Changes land through pull requests:
-  branch, **rebase onto the latest `origin/main` right before opening the PR and before every push
-  that updates it** (never merge `main` into a branch), push, open a PR, let CI run. A PR merges
-  (`gh pr merge --squash`) only after review and only when its green CI ran on top of current
-  `main` (`mergeStateStatus` CLEAN; rebase again if `main` moved); after a merge, `main`'s own CI
-  must pass. Never force-push `main`. Never commit `plan/`, `.agent-files/`, `worktrees/` or
-  `target*/`; check `git ls-files` before pushing.

 ## Running
 - `cargo run -p modelcraft-cli -- commands` lists every command with its parameters.
