What it does
Tech Debt Scan is an agent skill from jtenniswood/espcontrol. Research-only technical debt scan for this EspControl repository. Use when the user asks for a tech debt scan, cleanup backlog, maintainability review, messy or rushed implementation review, duplicated logic audit, fragile assumption scan, dead code review, architecture cleanup plan, or asks to identify code that works now but will be painful to maintain later.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Technical debt. The repository describes itself as: Esphome based smart home control panel.
When your agent uses it
- The user asks for a tech debt scan
- Cleanup backlog
- Maintainability review
- Rushed implementation review
Example prompts
- “/tech-debt-scan”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Inspect repository state.
- Map the project structure.
- Look for these debt patterns
- Validate each meaningful finding.
- Prioritize by practical impact.
What it can do on your machine
Read from SKILL.md and the folder at commit 72cf82c. 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 (its code samples are markdown).
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
Tech Debt Scan loads about 1.4k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 555 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 555 words (~1,432 tokens).
“Perform a research-only review of the repository and turn findings into a practical cleanup backlog. Do not implement fixes during the scan unless the user separately selects a backlog item and asks for it to be fixed.”
