At a glance

A skill your agent uses when reading JSON files in Go applications, especially for configuration files, data files, or any JSON parsing that requires comprehensive error handling for missing files…

  • Works in 4 steps: Define the Target Struct → Implement File Reading with Error Handling → Parse JSON with Validation → …
  • Reading JSON files in Go applications
  • SKILL.md covers Overview, When to Use, Process and Rules, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Go JSON File Reading is an agent skill from sandgardenhq/sgai. Use when reading JSON files in Go applications, especially for configuration files, data files, or any JSON parsing that requires comprehensive error handling for missing files, invalid JSON, and permission errors

Its SKILL.md is about 2.2k 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 Error handling. The repository describes itself as: Sandgarden AI Software Factory.

When your agent uses it

  • Reading JSON files in Go applications
  • Especially for configuration files
  • Any JSON parsing that requires comprehensive error handling for missing files
  • Permission errors

Example prompts

  • “/go-json-file-reading”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Define the Target Struct
  2. Implement File Reading with Error Handling
  3. Parse JSON with Validation
  4. Add Context and Logging

What it can do on your machine

Read from SKILL.md and the folder at commit 9efbb7b. 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 go).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • pkg.go.dev
    • go.dev

    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

Go JSON File Reading loads about 2.2k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 603 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~59
When it runs · the whole SKILL.md, loaded when a task matches
~2.2k

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 603 words (~2,234 tokens).

“This skill provides comprehensive patterns for reading JSON files in Go with proper error handling, context wrapping, and best practices. It addresses common failure modes like missing files, invalid JSON syntax, permission errors, and provides structured error messages for debugging.”
