knowledge-base-first

knowledge-base-first is a skill for Claude Code, Codex from Snorlax-zzZ/knowledge-base-system-oss. It costs 61 tokens per session (875 once invoked), scanned A, original, no licence file.

A skill that searches a project knowledge base before carrying out engineering work. A knowledge base is a collection of stored project information that an agent can search.

In plain words
What is it for?
Looking up relevant engineering information and including a trace ID and knowledge-item ID when a result is found.
Why use it?
It helps the agent use existing project knowledge before making implementation decisions. It can use an MCP connection first and an HTTP service if MCP is unavailable.

Good fit Looking up relevant engineering information and including a trace ID and knowledge-item ID when a result is found.

Token cost

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.

Security

Grade A, and why

knowledge-base-first 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 7d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

Changes

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.
