What it does
Format Lint Assistant is an agent skill from dmitriiweb/extract-emails. Run the project's formatter, linters, and mypy checks in the required order, fixing issues and managing any needed stub dependencies via uv.
Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/linting_rules.md`).
It sits in Development, covering Linting and formatting and Type safety. The repository describes itself as: Extract emails and links to linkedin accounts from URLs. The licence is MIT.
When your agent uses it
- Tasks that involve Linting and formatting
- Tasks that involve Type safety
Example prompts
- “/format-lint-assistant”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Prepare and format
- Lint and iterate
- Manage dependencies
- Validate and report
What it can do on your machine
Read from SKILL.md and the folder at commit 1f2bb40. 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:
makeuv
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, 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
Format Lint Assistant loads about 395 tokens when it runs, and up to ~624 if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 198 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.

Format and Lint Assistant
Quick start
- Run
make formatbefore linting to apply project formatting. - Run
make lint; fix linter errors first, rerunmake lint, then address any remaining mypy issues. - If mypy needs missing stubs/libs, add them with
uv add --dev <package>so they land inpyproject.toml; never use mypy's install-missing-libraries command. - Keep rerunning
make lintuntil it passes cleanly; share any unresolved issues. - See
references/linting_rules.mdfor the exact workflow.
Workflow
Prepare and format
- Review the scope of files to format/lint.
- Run
make formatto apply formatting before linting.
Lint and iterate
- Run
make lint. - If linters fail, fix those issues first and rerun
make lintto confirm the lint portion is clean. - After lint fixes, address mypy errors reported by the same command, then rerun
make lintto verify.
- Run
Manage dependencies
- When mypy reports missing libraries or type stubs, add the needed package with
uv add --dev <package>so it updates the dev dependencies inpyproject.toml. - Do not use mypy's automatic install-missing-libraries flag.
- When mypy reports missing libraries or type stubs, add the needed package with
Validate and report
- Run
make lintonce more after all fixes to ensure a clean result. - Summarize what was run, what was fixed, and call out any remaining issues.
