What it does
JSON To LLM Context is an agent skill from aiskillstore/marketplace. Turn JSON or PostgreSQL jsonb payloads into compact readable context for LLMs. Use when a user wants to compress JSON, reduce token usage, summarize API responses, or convert structured data into model-friendly text without dumping raw paths.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/rules.md` and `scripts/json_to_readable_context.py`).
It sits in Databases, covering LLM cost and token optimization and Schema markup. It works with PostgreSQL. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.
When your agent uses it
- A user wants to compress JSON
- Reduce token usage
- Summarize API responses
- Convert structured data into model-friendly text without dumping raw paths
Example prompts
- “/json-to-llm-context”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Confirm the input is valid JSON or jsonb-style JSON text.
- Run scripts/json_to_readable_context.py on the file or pipe JSON through stdin.
- Return the generated readable summary as the primary artifact.
- If the output still feels too long, rerun with tighter limits such as lower --max-samples,
- If parsing fails, report the JSON error clearly instead of guessing.
What it can do on your machine
Read from SKILL.md and the folder at commit 44923f3. 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
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
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
JSON To LLM Context loads about 1k tokens when it runs, and up to ~1.7k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 379 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 379 words (~1,044 tokens).
“Use this skill when raw JSON is too noisy for direct prompting. It converts JSON or exported jsonb content into short, readable summaries that preserve entities, status, relationships, and counts.”
