TDD is an agent skill from bernardladenthin/BitcoinAddressFinder. Test-Driven Development workflow for BitcoinAddressFinder — delegates to the generic Java TDD skill and adds project-specific context
Its SKILL.md is about 420 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-driven development. It works with Java and Bitcoin. The repository describes itself as: A high performance bitcoin address finder. The licence is Apache-2.0.
Read from SKILL.md and the folder at commit 138f2ef. It shows what the files ask for, not the result of running them.
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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
TDD loads about 424 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 133 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.
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.

Test-Driven Development workflow for BitcoinAddressFinder — delegates to the generic Java TDD skill and adds project-specific context. TDD is an agent skill from bernardladenthin/BitcoinAddressFinder.
TDD fits situations like: tasks that involve Test-driven development.
Run `npx skills add bernardladenthin/BitcoinAddressFinder --skill tdd -a claude-code`. Or copy the skill folder (.claude/skills/tdd in bernardladenthin/BitcoinAddressFinder) into .claude/skills/tdd in your project. Claude Code loads it when a task matches its description.
Run `npx skills add bernardladenthin/BitcoinAddressFinder --skill tdd -a codex`. Or copy the skill folder (.claude/skills/tdd in bernardladenthin/BitcoinAddressFinder) into .agents/skills/tdd in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bernardladenthin/BitcoinAddressFinder --skill tdd -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/tdd, .gemini/skills/tdd, .github/skills/tdd and .opencode/skills/tdd in your project.
SKILL.md names no scripts, command-line tools or credentials: TDD is instructions for the agent only.
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.
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.
TDD 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.
About 424 tokens (SKILL.md is roughly 1.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with TDD: Growing Outside In Systems (lexler/skill-factory, 239 stars), TDD Guide (LeoYeAI/openclaw-master-skills, 2.2k stars), 054 Design TDD (jabrena/plinth, 447 stars) and Test Driven Generation (ArabelaTso/Skills-4-SE, 253 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
