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 | $0.00017 | $0.00274 |
| Opus 5 | $0.00009 | $0.00137 |
| Sonnet 5 | $0.00003 | $0.00055 |
| Haiku 4.5 | $0.00002 | $0.00027 |
Grade A, and why
kb-store 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.
What it actually says
KB Store
Store a new knowledge entry in the knowledge bank.
FIRST: Load the knowledge-bank:knowledge-bank skill using the Skill tool, then execute Step 2b (STORE) from the skill.
If $ARGUMENTS is provided:
- Parse it as
[category] [title]— use these to pre-fill the entry. - Valid categories:
learnings,decisions,context,sessions
If $ARGUMENTS is empty:
- Infer what to store from the recent conversation context.
- Ask the user to confirm the title, category, and tags before writing.
The skill will:
- Gather title, category, tags, and content
- Create a dated markdown file under
.knowledge-bank/<category>/YYYY-MM/ - Append an index entry to the master and category
INDEX.mdfiles - Confirm the file path and assigned ID
For formal Architecture Decision Records, use /kb-adr instead.
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.
