At a glance

Write code other humans can read, change, and trust. An agent skill from flornkm/personal-site.

  • Works in 5 steps: The diff is the smallest one that solves… → A reader unfamiliar with the change can… → No file you created is over ~300 lines… → …

  • SKILL.md covers Plan before you code — but…, File and function size, Earn your abstractions and Reliability defaults, plus 3 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Reliable Maintainable Code is an agent skill from flornkm/personal-site. Write code other humans can read, change, and trust. Keep files small, plans concise, abstractions earned. Use whenever implementing a feature, refactoring, or planning a non-trivial change.

Its SKILL.md is about 940 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 Refactoring. The repository describes itself as: Florians personal site.

When your agent uses it

  • Implementing a feature
  • Planning a non-trivial change

Example prompts

  • “/reliable-maintainable-code”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. The diff is the smallest one that solves the problem.
  2. A reader unfamiliar with the change can guess what each touched function does from its name.
  3. No file you created is over ~300 lines without a reason you can state in one sentence.
  4. There is nothing left half-done, commented out, or marked TODO without a concrete trigger.
  5. You have actually run the thing (typecheck, test, or the feature in the UI) — not just looked at the code.

What it can do on your machine

Read from SKILL.md and the folder at commit acc40c8. 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

Reliable Maintainable Code loads about 943 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 565 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~943

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 565 words (~943 tokens).

“The next person to open this file should be able to understand it without you in the room. Optimize for clarity, small surface area, and reversibility — not cleverness, not future-proofing, not personal style.”
