The file
We split this skill into the rules it gives an agent
1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

Start from a guaranteed clean state: remove stale artifacts and intermediates, restore any patched config, before you begin.
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

The rule
Build and release code has a different discipline than feature code: it must be reproducible, abortable, and reversible. A build that depends on whatever the last run left behind is unreliable by definition. Before you change a build step, ask what happens if it crashes halfway, and whether you could undo the release after it ships.
Fires when
Editing a build script, a release or packaging step, a publish flow, or CI config.
How to apply
- Start from a guaranteed clean state: remove stale artifacts and intermediates, restore any patched config, before you begin.
- Smoke-test the smallest case first and abort fast if it fails; don't run the full matrix on a setup you haven't proven.
- Version artifacts into timestamped outputs instead of overwriting, so rollback is trivial.
- Validate outputs, not just inputs. A silently-empty artifact, or a "0 tests passed" nobody asserted on, is the worst failure mode and the easiest to miss.
- Protect any global state you patch-and-restore with a lock, so a half-finished run doesn't leave the machine broken.
- Know the rollback before you ship.
Worked example
A release script builds against eight SDK versions over an hour, then you discover the first one was broken from the start — the whole hour is wasted. A canary fixes it: build the smallest target first, and abort the run if it fails, so a broken setup costs two minutes instead of sixty. The same instinct catches a "0 tests passed" that would otherwise ship green because nobody asserted the count was above zero — a loud failure is always better than a silent bad artifact.
Red flags
| Thought | Reality |
| "The machine's probably clean" | Probably is not a guarantee; start clean. |
| "It built, so it's good" | Built is not the same as validated. Check the output. |
| "I'll just overwrite the last build" | Then you can't roll back when this one's bad. |
| "All eight will be fine" | Smoke-test one before you spend an hour on eight. |
