What it does
Zero Tech Debt is an agent skill from jnsahaj/skills. Rework a change as if the intended UX and architecture existed from day one, deleting compatibility cruft and accidental complexity.
Its SKILL.md is about 350 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 Development, covering Technical debt. The repository describes itself as: Agent skills I use daily.
When your agent uses it
- Tasks that involve Technical debt
Example prompts
- “/zero-tech-debt”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- State the intended end state in one or two sentences.
- Search for real callers before preserving compatibility.
- Reshape around the final product surface.
- Move shared rules to one place.
- Verify the intended flow.
What it can do on your machine
Read from SKILL.md and the folder at commit 170b0b9. 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
Zero Tech Debt loads about 354 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 190 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 190 words (~354 tokens).
“Rework the change from the intended end state, not from the historical path that produced the current patch.”
