regression-manage

regression-manage is a skill for Claude Code from vibeic/vibe-ic. It costs 72 tokens per session (1,309 once invoked), scanned A, original, Apache-2.0.

A workflow for managing repeated test runs, such as nightly or continuous-integration regressions. It groups failures, investigates flaky tests, summarises results, classifies severity, and assigns owners.

In plain words
What is it for?
Use it after CI or nightly runs, when a critical failure appears, when tests are unreliable, or during a review of regression health.
Why use it?
It helps teams keep large test suites under control and route failures to the people who can fix them.

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

regression-manage 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tests/test_compliance.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Regression Manage

Doctrine (v0.1.50): 把修法寫進工具,而非寫進 prompt. Programs first; AI is the backstop for owner-assignment narrative.

Once verification, synthesis, P&R, and signoff are scripted, the next bottleneck is keeping the regression green. This skill triages nightly / CI results and routes failures to the right skill / owner.

Mandatory Deterministic Preflight

# Validate every incoming regression-failure issue has fixture data:
python3 plugins/vibe-ic/programs/regression_issue_intake_check.py \
    --issue <issue.json> --strict

The intake gate rejects issues without a verbatim repro snippet, expected output, or drop-in fixture — exactly the pattern that preceded the historical #5 thrashing loop. Do not start triage on an issue that fails intake. Refuse to "diagnose by reading the log" without the program's PASS.

When to use

  • After each nightly regression completes
  • When a critical failure appears mid-day
  • When flaky tests are slowing down the team
  • Weekly regression health review

Inputs

  1. Regression run log / database (Jenkins, LSF, Slurm, GitHub Actions)
  2. Known-failure list with owners
  3. Severity policy (tape-out blocker vs warning vs info)
  4. Branch / tag under test

Workflow

The five mechanical steps are deterministic and are now programs, not prose. Run them in order; each emits a JSON report (--json <out>):

  1. Aggregate results (pass/fail/error/timeout per job, pass %, trend, P0 count) — enforced by programs/regression_report_aggregate.py.
  2. Deduplicate (normalize-and-hash the failure signature so identical failures collapse to one issue) — enforced by programs/regression_failure_dedup.py.
  3. Classify severity (P0 was-green-now-red on protected/release; P1 new failure on feature branch; P2 flaky passes-on-retry; P3 environmental license/disk/network) — enforced by programs/regression_severity_classify.py.
  4. Auto-triage (failing-step → target skill: timing→/sta-review, DRC→/drc-fix, functional→/rtl-repair, formal→/formal-verify, …) — enforced by programs/regression_failure_route.py.
  5. Flaky-test quarantine (pass-on-retry AND fail → quarantine + open ticket so flakes don't hide real regressions) — enforced by programs/regression_flaky_quarantine.py.

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.

regression-manage is a skill published in the GitHub repository vibeic/vibe-ic (23 stars, last pushed today), licensed Apache-2.0. It adds 72 tokens to every session and 1,309 once invoked, about $0.0004 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 2026-09-03.
