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 | $0.00070 | $0.02480 |
| Opus 5.5 | $0.00028 | $0.00992 |
| Sonnet 5.5 | $0.00014 | $0.00496 |
| Haiku 4.5 | $0.00007 | $0.00248 |
Grade A, and why
kb-query 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.

KB Query Skill
Purpose
Interactive Knowledge Base search with natural language queries, providing fast access to institutional knowledge through relevance-ranked results with quality scoring.
How It Works
Step 1: Accept Query
User provides search query or problem description:
User: "Search KB for database connection pool issues"
Step 2: Execute Search
Run KB search with intelligent parameters:
# Basic search
make kb-search QUERY="database connection pool"
# With category filter
make kb-search QUERY="JWT authentication" CATEGORY=AUTH
# With quality threshold
make kb-search QUERY="performance optimization" MIN_SCORE=70
# All parameters
make kb-search QUERY="redis cache" CATEGORY=CACHE MIN_SCORE=60 LIMIT=10
Step 3: Display Results
Show top results with relevance and quality scores:

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.
- 1mo ago First seen · 392 lines · 70 tokens per session scan A 2566d849b386
kb-query is a skill published in the GitHub repository davidmatousek/tachi (94 stars, last pushed 4d ago), licensed Apache-2.0. It adds 70 tokens to every session and 2,480 once invoked, about $0.0003 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 2026-08-30.
