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.

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 | $0.00092 | $0.01260 |
| Opus 5 | $0.00046 | $0.00630 |
| Sonnet 5 | $0.00018 | $0.00252 |
| Haiku 4.5 | $0.00009 | $0.00126 |
Grade A, and why
qlint-snippet 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 11d 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
qlint-snippet
Run KX qlint on a single q/qSQL code snippet via the scripts/run.sh script bundled with this skill (sibling scripts/ directory next to this SKILL.md). Useful for:
- ad-hoc syntax checks on a code block pasted into the chat
- Claude auto-validating q code it just generated before presenting it to the user
Prerequisites
QLINT_DIR must point to the directory containing KX's qlint.q_ — there is no default; the wrapper exits with code 2 and a clear stderr message if it is unset or the file is missing. q is expected on PATH; override with the Q env var if not. If you don't have KX Developer installed, see this plugin's README for the recommended setup.
If QLINT_DIR is unset or qlint.q_ is missing (exit 2), ASK THE USER for the correct path. Do not run find / or other filesystem-wide searches to locate it unless the user explicitly requests — they are slow and the user already knows where it lives. A narrow check in obvious places (e.g. ~/.kx, the plugin's own directory) is fine as a one-shot, but anything broader should be a question.
Gather parameters
| Parameter | Default | Description |
|---|---|---|
CODE |
required | The q snippet to lint. Take it from the user's message (fenced block, inline quote, or explicit myCode variable). Strip any markdown fences before passing. |
Execute
Invoke the scripts/run.sh script bundled with this skill (under the scripts/ directory sibling to this SKILL.md). Pass the snippet via argument or stdin. Stdin (heredoc) is strongly preferred for multi-line code — see the gotcha below.
# Stdin form (preferred for multi-line — quoted heredoc disables all expansion)
scripts/run.sh <<'EOF'
<the snippet here, possibly multi-line>
EOF
# Argument form (one-liner, single-line code)
scripts/run.sh '<the snippet>'
Use the absolute path to scripts/run.sh (resolved from the skill's own directory) so it works regardless of the caller's current working directory.
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.

qlint-snippet is a skill published in the GitHub repository KxSystems/kx-skills (17 stars, last pushed 9d ago), licensed Apache-2.0. It adds 92 tokens to every session and 1,260 once invoked, about $0.0005 per session on Opus 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 2026-08-30.
