What it does
Long Task TDD is an agent skill from suriyel/longtaskforagent. Use when implementing a feature through TDD in a long-task project - enforces Red-Green-Refactor cycle
Its SKILL.md is about 4.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `prompts/implementer-prompt.md`, `references/ui-error-detection.md` and `testing-anti-patterns.md`).
It sits in Testing & QA, covering Test-driven development.
When your agent uses it
- Implementing a feature through TDD in a long-task project - enforces Red-Green-Refactor cycle
- Tasks that involve Test-driven development
Example prompts
- “/long-task-tdd”
Requirements
- Python 3
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- TDD Red — Write Failing Tests
- TDD Green — Minimal Implementation
- TDD Refactor
What it can do on your machine
Read from SKILL.md and the folder at commit ca67fe1. 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
Shell commands in SKILL.md call:
pythonbashnpxmvnmypy
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
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
Long Task TDD loads about 4.4k tokens when it runs, and up to ~8.2k if it reads all its reference files. Until then it costs about 29 tokens; SKILL.md has 2,177 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.
- NoteMentions a .env fileSKILL.md:155
ucture** | Use project test environment (.env.test, test DB, localhost test server) — never production resources |
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 2,177 words (~4,423 tokens).
“Write the test first. Watch it fail. Write minimal code to pass. Refactor.”
