About this skill
TiDB Failpoint Test Runner is a skill in pingcap/tidb (41k stars). Its SKILL.md is about 256 tokens. Licence: Apache-2.0.
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Use docs/agents/testing-flow.md -> Failpoint decision for unit tests to decide whether the package needs failpoint enablement.
- Run the matching command set from docs/agents/testing-flow.md
- Keep the run targeted with -run ; for Bazel-specific variants, see the Bazel notes in docs/agents/testing-flow.md -> Failpoint-enabled run.
- Record the decision evidence and exact test command in the final report.
What it can do on your machine
Read from SKILL.md and the folder at commit 7a3dacb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
TiDB Failpoint Test Runner loads about 256 tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 103 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

TiDB Failpoint Test Runner
Overview
Follow this workflow before running package tests under pkg/....
-tags=intest,deadlock does not enable failpoints.
Canonical command details live in docs/agents/testing-flow.md -> Failpoint decision for unit tests.
Workflow
- Use
docs/agents/testing-flow.md->Failpoint decision for unit teststo decide whether the package needs failpoint enablement. - Run the matching command set from
docs/agents/testing-flow.md:Failpoint-enabled runwhen the package matches the failpoint checks.Unit tests (/pkg/...)when it does not.
- Keep the run targeted with
-run <TestName>; for Bazel-specific variants, see the Bazel notes indocs/agents/testing-flow.md->Failpoint-enabled run. - Record the decision evidence and exact test command in the final report.
