What it does
Validate Tests is an agent skill from gittower/git-flow-next. Codex-gate the test plan in an implementation plan before implementation starts
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Test generation and Planning. It works with Git. The repository describes itself as: A modern reimplementation of git-flow in Go that offers greater flexibility while maintaining backward compatibility with the original git-flow and git-flow-avh.
When your agent uses it
- Tasks that involve Test generation
- Tasks that involve Planning
Example prompts
- “/validate-tests”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Edit, Write, Bash, Agent
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Find the Plan
- Local Validation
- Codex Gate
- Evaluate and Apply
- Report Findings
What it can do on your machine
Read from SKILL.md and the folder at commit 00d1b4b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobEditWriteBashAgent
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
Validate Tests loads about 660 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 312 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Grep, Glob, Edit, Write, Bash, Agent
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 312 words (~660 tokens).
“Gate the test plan of an implementation plan before any implementation starts. Combines a local check against the testing guidelines with an external Codex review, following the shared convention in ../_shared/CODEX_GATE.md.”

Questions about Validate Tests
What does Validate Tests do?
Codex-gate the test plan in an implementation plan before implementation starts. Validate Tests is an agent skill from gittower/git-flow-next.
When should I use Validate Tests?
Validate Tests fits situations like: tasks that involve Test generation; tasks that involve Planning.
How do I install Validate Tests in Claude Code?
Run `npx skills add gittower/git-flow-next --skill validate-tests -a claude-code`. Or copy the skill folder (.claude/skills/validate-tests in gittower/git-flow-next) into .claude/skills/validate-tests in your project. Claude Code loads it when a task matches its description.
How do I install Validate Tests in Codex?
Run `npx skills add gittower/git-flow-next --skill validate-tests -a codex`. Or copy the skill folder (.claude/skills/validate-tests in gittower/git-flow-next) into .agents/skills/validate-tests in your project. Codex loads it when a task matches its description.
Can I use Validate Tests in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add gittower/git-flow-next --skill validate-tests -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/validate-tests, .gemini/skills/validate-tests, .github/skills/validate-tests and .opencode/skills/validate-tests in your project.
What does Validate Tests need to run?
SKILL.md names no scripts, command-line tools or credentials: Validate Tests is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob, Edit, Write, Bash, Agent.
Does Validate Tests access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Validate Tests safe to install?
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Validate Tests use?
Validate Tests has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Validate Tests use?
About 660 tokens (SKILL.md is roughly 2.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
