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.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 410 Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next.

What it costs to keep this loaded
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 | $0.00035 | $0.03148 |
| Opus 5 | $0.00017 | $0.01574 |
| Sonnet 5 | $0.00007 | $0.00630 |
| Haiku 4.5 | $0.00003 | $0.00315 |
Grade B, and why
jq-json-processing scanned grade B with 2 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 9d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

jq JSON Processing
Expert knowledge for processing, querying, and transforming JSON data using jq, the lightweight and flexible command-line JSON processor.
When to Use This Skill
| Use this skill when... | Use yq-yaml-processing instead when... |
|---|---|
| Extracting or filtering fields in JSON input | Working with YAML files (Kubernetes, GH Actions, Helm) |
Parsing gh, curl, or kubectl -o json responses |
Editing YAML in place while preserving comments |
| CI pipelines on minimal images (jq is universally installed) | Converting YAML → JSON before processing |
| Use this skill when... | Use nushell-data-processing instead when... |
|---|---|
| One-off pipeline transforms that fit in a single expression | Multi-step transforms that span JSON, YAML, CSV, and TOML |
| Stdin-piped JSON from another command | Aggregations, group-by, or visual table exploration |
Core Expertise
JSON Operations
- Query and filter JSON with path expressions
- Transform JSON structure and shape
- Combine, merge, and split JSON data
- Validate JSON syntax and structure
Data Extraction
- Extract specific fields from JSON objects
- Filter arrays based on conditions
- Navigate nested JSON structures
- Handle null values and missing keys
Essential Commands
Basic Querying
# Pretty-print JSON
jq '.' file.json
# Extract specific field
jq '.fieldName' file.json
# Extract nested field
jq '.user.email' file.json
# Extract array element
jq '.[0]' file.json
jq '.items[2]' file.json
Array Operations
# Get array length
jq '.items | length' file.json
# Map over array
jq '.items | map(.name)' file.json
# Filter array
jq '.items[] | select(.active == true)' file.json
jq '.users[] | select(.age > 18)' file.json
# Sort array
jq '.items | sort_by(.name)' file.json
jq '.items | sort_by(.date) | reverse' file.json
# Get first/last elements
jq '.items | first' file.json
jq '.items | last' file.json
# Unique values
jq '.tags | unique' file.json
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 9d ago First seen · 460 lines · 35 tokens per session scan B 9529d182787c
jq-json-processing is a skill published in the GitHub repository Kilo-Org/kilo-marketplace (175 stars, last pushed 22d ago), licensed Apache-2.0. It adds 35 tokens to every session and 3,148 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
