gf-regression

A read-only regression checker for the gf command-line tool, which supports GitHub, GitLab, and GitCode.

In plain words
What is it for?
Checking gf after code changes, preparing a release, diagnosing command-line failures, and reporting genuine test failures for later investigation.
Why use it?
It shows which smoke tests pass, fail, or are skipped without changing scripts or remote repositories.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gf-regression scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 354 lines — stays where its author put it; the contents beside it link to each section on GitHub.

gf-regression

Runs scripts/smoke-test.sh, parses PASS/FAIL/SKIP, delegates real failures to /gf-autoreport-bug. Defaults to --read-only. Does not fix bugs, edit scripts, or modify remotes.

CLI Requirement

MUST use gf CLI, NOT gh CLI.

CLI Scope Platform Support
gf This project GitHub + GitLab + GitCode
gh GitHub only GitHub only

Why: gf is the unified CLI for this project. Using gh breaks GitLab/GitCode compatibility.

Preconditions

  • gf installed: command -v gf
  • gf authenticated: gf auth status

When to Use

Use this skill when you need to verify that the gf CLI is working correctly after changes, before release, or when debugging CLI-related issues.

Specific Scenarios

# Scenario Trigger Phrase Expected Action
1 Post-change verification "verify my changes didn't break gf" Run read-only smoke test, report PASS/FAIL
2 Pre-release gate "run pre-release checks" Run smoke test as part of release preparation
3 Debugging CLI issues "gf commands are failing" Run smoke test to identify which operations fail
4 Quick health check "is gf working?" Run minimal smoke test, report status
5 Regression detection "check for regressions" Run full smoke test, compare with baseline

Language-Specific Triggers

English 中文 Context
smoke test 冒烟测试 Quick CLI health check
regression test 回归测试 Post-change verification
pre-release check 发版前检查 Before publishing release
verify CLI 验证 CLI Confirm CLI functionality
gf is broken gf 坏了 Debug CLI failures

When NOT to Use

Do NOT use this skill in the following scenarios:

Scenario Why Not Use Instead
Fixing a bug This skill only detects and reports bugs, doesn't fix them /gf-workflow for bug fixes
Code review This skill runs tests, doesn't review code /gf-pr-review for code review
Full quality gate This skill only runs smoke tests, not full CI /gf-quality for complete quality checks
Testing other projects This skill is designed for gf CLI only Use project-specific test commands
CI pipeline Smoke tests with autoreport shouldn't run in CI Use scripts/smoke-test.sh directly with exit code
Performance testing This skill checks functionality, not performance Use benchmarking tools

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

gf-regression is a skill published in the GitHub repository byx-darwin/gitflow-cli (2 stars, last pushed 2d ago), licensed MIT. It adds 60 tokens to every session and 2,885 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
