What it does
Strategic Testing is an agent skill from FranciscoMoretti/chat-js. Decide whether a change warrants new tests and choose proportionate verification. Use before adding tests, when planning validation, or when reviewing whether a proposed test protects meaningful behavior.
Its SKILL.md is about 220 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with OpenAI and Google Gemini. The repository describes itself as: Production-ready AI chat. Start here and make it your own. Formerly Sparka AI. The licence is Apache-2.0.
Example prompts
- “/strategic-testing”
What it can do on your machine
Read from SKILL.md and the folder at commit 7da0efb. 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
Strategic Testing loads about 223 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 90 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.

- description
- Decide whether a change warrants new tests and choose proportionate verification. Use before adding tests, when planning validation, or when reviewing whether a proposed test protects meaningful behavior.
Strategic testing
Add tests only when they protect meaningful behavior or a stable contract that existing checks could realistically miss.
- Prioritize domain invariants, important edge cases, public interfaces, persisted data, security boundaries, and integration seams.
- Skip tests for mechanical edits, implementation details, existing coverage, or changes already verified by types, linting, or schema validation.
- Choose the smallest test level that protects the behavior.
Before adding a test, identify the realistic failure it prevents and confirm that the maintenance cost is justified. If that case is weak, do not add one.

How do I install Strategic Testing in Claude Code?
Run `npx skills add FranciscoMoretti/chat-js --skill strategic-testing -a claude-code`. Or copy the skill folder (.agents/skills/strategic-testing in FranciscoMoretti/chat-js) into .claude/skills/strategic-testing in your project. Claude Code loads it when a task matches its description.
How do I install Strategic Testing in Codex?
Run `npx skills add FranciscoMoretti/chat-js --skill strategic-testing -a codex`. Or copy the skill folder (.agents/skills/strategic-testing in FranciscoMoretti/chat-js) into .agents/skills/strategic-testing in your project. Codex loads it when a task matches its description.
Can I use Strategic Testing 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 FranciscoMoretti/chat-js --skill strategic-testing -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/strategic-testing, .gemini/skills/strategic-testing, .github/skills/strategic-testing and .opencode/skills/strategic-testing in your project.
What does Strategic Testing need to run?
SKILL.md names no scripts, command-line tools or credentials: Strategic Testing is instructions for the agent only.
Does Strategic Testing 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 Strategic Testing safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Strategic Testing use?
Strategic Testing is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Strategic Testing use?
About 223 tokens (SKILL.md is roughly 892 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
