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 | $0.00102 | $0.03536 |
| Opus 5 | $0.00051 | $0.01768 |
| Sonnet 5 | $0.00020 | $0.00707 |
| Haiku 4.5 | $0.00010 | $0.00354 |
Grade A, and why
logsql 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 2d 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 — 428 lines — stays where its author put it; the contents beside it link to each section on GitHub.
LogsQL
VictoriaLogs query language. Three stages: filters select logs, pipes transform, stats aggregate. Master the shape; rest is detail.
References
- Filters — [
${CLAUDE_SKILL_DIR}/references/filters.md] All filter types (word, phrase, prefix, substring, regexp, range, IPv4/IPv6/string range, length range, exact, multi-exact, contains_all/any, subquery, case-insensitive, sequence, value_type, field comparison);_time,_stream,_stream_id; AND/OR/NOT precedence. - Pipes — [
${CLAUDE_SKILL_DIR}/references/pipes.md] All pipe operators: field manipulation, sorting/limiting, transformation, structured parsing, exploration, stream context, joining. - Stats — [
${CLAUDE_SKILL_DIR}/references/stats.md] Stats pipe shape, grouping (fields, time buckets, timezone-aware, field buckets, IPv4 buckets, additional filters); all stats functions;running_stats/total_stats; math pipe. - Patterns — [
${CLAUDE_SKILL_DIR}/references/patterns.md] Recipes (top-N, error counting, latency percentiles, field extraction, rate over time), performance tips, troubleshooting workflows.

The Three-Stage Shape
<filters> | <pipe1> | <pipe2> | ... | <pipeN>
- Filters select logs. At least one required. Run first; downstream sees only matched logs.
- Pipes transform. Each reads previous-stage output, emits new rows. Reshape (
fields,rename), parse (unpack_json,extract), aggregate (stats), limit (limit,sort). - No final stage marker. Last pipe's output is the response.
Simplest valid query — one word, searched in _msg:
error
Returns every log containing error, in arbitrary order, across all time.
The _time Filter — Almost Always Required
Without _time, the query scans all stored logs.
Common forms:
_time:5m— last 5 minutes._time:1h— last hour._time:1d— last day._time:2.5d15m42.345s— composite duration._time:>=2024-01-01— since._time:<=2024-01-01— before._time:[2024-01-01, 2024-01-02)— closed-open range._time:2024-03-15T10:00:00+02:00— exact RFC3339 with timezone.
What ships with it
5 files 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.

logsql is a skill published in the GitHub repository xobotyi/cc-foundry (20 stars, last pushed 2d ago), licensed MIT. It adds 102 tokens to every session and 3,536 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.
