Language-neutral code quality rules for eserstack, TypeScript and Go.

  • Handling errors
  • SKILL.md covers Always and References
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Calling external services

What it does

Coding Practices is an agent skill from eser/stack. Language-neutral code quality rules for eserstack, TypeScript and Go. Covers errors, logging, explicit checks, naming and comments, timeouts and resource bounds, streaming, background work, input and config sources, and performance claims. Use when writing or reviewing code, handling errors, adding logs or calling external services. Not for syntax (use javascript-practices or go-practices).

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `evals/triggers.json`, `references/errors.md` and `references/inputs-and-config.md`).

It sits in Development, covering Code quality. It works with JavaScript and TypeScript. The repository describes itself as: The Portability Solution for Your Code! 🚀 Powered By Deno and JavaScript.

When your agent uses it

  • Handling errors
  • Calling external services

Example prompts

  • “/coding-practices”

What it can do on your machine

Read from SKILL.md and the folder at commit 64939e6. 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

Coding Practices loads about 688 tokens when it runs, and up to ~8.3k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 223 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~103
When it runs · the whole SKILL.md, loaded when a task matches
~688
With references · SKILL.md plus every file in references/, read only if the agent opens them
~8.3k

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 223 words (~688 tokens).

“Rules that hold in every language in this repository. Language syntax lives in javascript-practices and go-practices; design patterns in design-principles.”
