Implement pre-commit checks without slowing down developers
Pre-commit hooks should only perform fast, deterministic checks of changed files; comprehensive testing remains the responsibility of the central pipeline.
"Implementing Fast Pre-Commit Checks" is considered here from the perspective of "Tests and Release Gates." For developers and technical project managers, "short runtime" and "slow hook" are particularly important.

Which checks belong in pre-commit without noticeably slowing down the workflow?
Formatting, syntax, simple static rules, and secret detection belong locally in the short commit path. Network, integration, and browser tests remain reserved for reproducible central jobs.
Local benefits
Error types are sorted by runtime, determinism, and earliest meaningful checkpoint.
Only fast file-related rules run in the hook; heavy-duty tests move to CI.
Runtime and workarounds are monitored, and the sentence size is regularly reduced.
Limit case: "Hook too slow"
A commit formats modified files, checks syntax, and searches for secrets without network access. The subsequent push initiates integration tests with the database and browser; this keeps the local cycle short while maintaining complete central control.
Short runtime
Test criterion
Short runtime
The check finishes quickly enough to be accepted with every commit.
Test criterion
Local benefits
The error can be clearly identified and corrected without an external environment.
Same rule – CI repeats the same check and prevents workarounds from becoming permanent paths.
Same rule
Control signal
Signal 1
Median, slow outliers, and most frequent causes of local check time per check step.
Control signal
Signal 2
CI errors that a suitable fast pre-commit check could have detected.
Hook that is too slow.
Hook that is too slow. Developers bypass or bundle commits because each run takes a long time to complete.
Environment Dependency – Network or local services produce unreliable results and lead to repetitions or deliberate circumvention.
Local Control Only – A skipped hook allows unchecked code to pass if the same mandatory rules are not run again in the pipeline.

Conclusion: Implementing Fast Pre-Commit Checks
Early checks are only effective if they remain fast and reliable. Test depth increases along the delivery path and reiterates mandatory rules in the central pipeline.
Sources and Further Information
The following sources document the technical and methodological guidelines used for "Implementing Fast Pre-Commit Checks."
Secure Software Development Framework Version 1.1 – NIST SP 800-218NIST defines verifiable development, testing, and release practices for secure software delivery.
Deployments and environments – GitHub DocsThe official documentation describes environments, protection rules, releases, branch restrictions, and secret access in deployment workflows.
Key Thesis
Formatting, syntax, simple static rules, and secret detection can run locally if they take only seconds. Slower integration and browser tests are run centrally and reproducibly after the push.
What This Is Not About
Pre-commit is not the place for the complete integration or browser suite.
What it's about
Fast deterministic checks prevent local root causes; slower tests run centrally after the push.

Same rule: first task
The runtimes of existing hooks are initially measured according to a rule. Slow or unstable candidates can then be moved to a suitable CI job.
