Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00160 | $0.02535 |
| Opus 5.5 | $0.00064 | $0.01014 |
| Sonnet 5.5 | $0.00032 | $0.00507 |
| Haiku 4.5 | $0.00016 | $0.00253 |
Grade A, and why
openclaw-json-toolkit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 234 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenClaw JSON Toolkit v2.0
The Swiss Army knife for JSON — 6 tools, zero install, instant results.
Quick Reference
| Situation | Action | Tool |
|---|---|---|
| Messy single-line JSON from an API | Pretty-print with 2-space indent | json_format |
| Need to minify for production | Compress to single line | json_format (minify) |
| Pasted JSON won't parse | Find exact error line + column | json_validate |
| Two config files changed | See added/removed/changed paths | json_diff |
| Need one field from 500-line JSON | Query with JSONPath expression | json_query |
| Deeply nested keys hard to access | Flatten to dot-notation | json_transform |
| Building an API contract | Auto-generate draft-07 schema | json_schema_generate |
What's New in v2.0
- :zap: CloudEdge Protocol -- All processing runs on Cloudflare's global edge network. Sub-100ms response worldwide, zero cold starts.
- :mag: DeepQuery Engine -- Full JSONPath with deep scan (
..), wildcards (*), filter expressions (?(@.price < 10)), and array slicing ([0:5]). - :shield: Schema Draft-07 Intelligence -- Auto-detects semantic formats: email, URI, date-time, IPv4, UUID. Infers
requiredfields andenumcandidates from sample data. - :arrows_counterclockwise: StructureMorph Transform -- Recursive flatten/unflatten, key renaming with mapping objects, pick/omit projections on arbitrarily nested JSON.

Detection Triggers
This skill activates when you say:
- "format this JSON" / "pretty print this" / "indent this JSON"
- "validate my JSON" / "is this valid JSON" / "why won't this parse"
- "compare these two JSON" / "diff these objects" / "what changed between these configs"
- "query this JSON" / "extract from JSON" / "JSONPath" / "get the nested value"
- "flatten this JSON" / "restructure this" / "rename these keys" / "unflatten"
- "generate a schema" / "create JSON Schema" / "schema from this sample"
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openclaw-json-toolkit is a skill published in the GitHub repository yedanyagamiai-cmd/openclaw-mcp-servers (4 stars, last pushed 7mo ago), licensed MIT. It adds 160 tokens to every session and 2,535 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
