What it does
Querying JSON is an agent skill from SebastienDegodez/copilot-instructions. Use when querying JSON files, filtering or transforming JSON data, or extracting specific fields from large JSON files without loading entire file contents (saves 80-95% context)
Its SKILL.md is about 970 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `reference/jq-guide.md`).
It sits in Development. The repository describes itself as: A comprehensive codebase of best practices, coding rules, and workflow automation for AI-assisted development with GitHub Copilot. Includes DDD, Clean Architecture, testing… The licence is Apache-2.0.
When your agent uses it
- Querying JSON files
- Transforming JSON data
- Extracting specific fields from large JSON files without loading entire file contents (saves 80-95% context)
Example prompts
- “/querying-json”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 0f0dccf. 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:
jq
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
Querying JSON loads about 970 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 367 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.

- querying-json
- description
- Use when querying JSON files, filtering or transforming JSON data, or extracting specific fields from large JSON files without loading entire file contents (saves 80-95% context)
jq: JSON Data Extraction Tool
Always invoke querying-json skill to extract JSON fields - do not execute bash commands directly.
Use jq to extract specific fields from JSON files without loading entire file contents into context.
When to Use jq vs Read
Use jq when:
- Need specific field(s) from structured data file
- File is large (>50 lines) and only need subset
- Querying nested structures
- Filtering/transforming data
- Saves 80-95% context vs reading entire file
Just use Read when:
- File is small (<50 lines)
- Need to understand overall structure
- Making edits (need full context anyway)
Common File Types
JSON files where jq excels:
- package.json, tsconfig.json
- Lock files (package-lock.json, yarn.lock in JSON format)
- API responses
- Configuration files
Default Strategy
Invoke querying-json skill for extracting specific fields from JSON files efficiently. Use instead of reading entire files to save 80-95% context.
Common workflow: finding-files skill → querying-json skill → other skills (fuzzy-selecting, replacing-text, viewing-files) for extraction and transformation.
Quick Examples
# Get version from package.json
jq -r .version package.json
# Get nested dependency version
jq -r '.dependencies.react' package.json
# List all dependencies
jq -r '.dependencies | keys[]' package.jsonPipeline Combinations
- querying-json | fuzzy-selecting: Interactive selection from JSON data
- querying-json | replacing-text: Transform JSON to other formats
- querying-json | viewing-files: View extracted JSON with syntax highlighting
Skill Combinations
For Discovery Phase
- finding-files → querying-json: Find JSON config files and extract specific fields
- searching-text → querying-json: Find JSON usage patterns and extract values
- extracting-code-structure → querying-json: Understand API structures before extraction

For Analysis Phase
- querying-json → fuzzy-selecting: Interactive selection from structured data
- querying-json → viewing-files: View extracted data with syntax highlighting
- querying-json → analyzing-code: Extract statistics from JSON output
For Refactoring Phase
- querying-json → replacing-text: Transform JSON data to other formats
- querying-json → querying-yaml: Convert JSON to YAML for different tools
- querying-json → xargs: Use extracted values as command arguments
Multi-Skill Workflows
- querying-json → querying-yaml → replacing-text → viewing-files: JSON to YAML transformation with preview
- querying-json → fuzzy-selecting → xargs: Interactive selection and execution based on JSON data
- finding-files → querying-json → searching-text: Find config files, extract values, search usage
Common Integration Examples
# Extract and select dependencies
jq -r '.dependencies | keys[]' package.json | fzf --multi | xargs npm info
# Get and filter package versions
jq -r '.devDependencies | to_entries[] | "\(.key)@\(.value)"' package.json | fzfNote: Choosing Between jq and yq
- JSON files (package.json, tsconfig.json): Use
jq - YAML files (docker-compose.yml, GitHub Actions): Use
yq
