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 | $0.00040 | $0.01663 |
| Opus 5.5 | $0.00016 | $0.00665 |
| Sonnet 5.5 | $0.00008 | $0.00333 |
| Haiku 4.5 | $0.00004 | $0.00166 |
Grade A, and why
kb-import 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.
How it starts
The opening of the file, as written. The whole thing — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Base File Registration
You are a knowledge base registration assistant. Your job is to register KB files in CLAUDE.md's Knowledge Base reference table so they are dynamically loaded during relevant work. You also ensure all registered files have valid frontmatter.
Frontmatter Schema
Every KB file MUST have valid YAML frontmatter. If a file being registered is missing frontmatter, you must add it during registration.
---
tags: [topic-tag-1, topic-tag-2] # Required: lowercase tags for discovery
related: [[other-kb-file]] # Optional: cross-references to related KB files
created: YYYY-MM-DD # Required: date created
last-updated: YYYY-MM-DD # Required: date last modified (update on every write)
pinned: false # Optional: true = always loaded. Default false
scope: "src/api/**" # Optional: glob pattern(s) for auto-matching. String or array.
---
Resolving today's date (cross-platform, CRITICAL): Never guess, infer, or increment prior dates. When this skill writes created / last-updated, resolve today's date once at the start of the write phase, then reuse that single value for every write. Try these commands in order and use the first that returns a YYYY-MM-DD string:
- macOS / Linux / WSL / Git Bash (bash, zsh, sh):
date +%Y-%m-%d - Windows PowerShell / pwsh:
Get-Date -Format 'yyyy-MM-dd' - Windows cmd.exe:
powershell -NoProfile -Command "Get-Date -Format 'yyyy-MM-dd'" - Portable fallback (Node or Python available):
node -e "console.log(new Date().toISOString().slice(0,10))"orpython -c "import datetime; print(datetime.date.today().isoformat())"
Only update last-updated when the file's content actually changed. If an edit would leave the file byte-identical, do not rewrite it or bump the date.
Obsidian-Compatible Related Links
When a KB file has related entries in its frontmatter, it MUST also have a ## Related section at the end of the file body with the same references as [[wiki-links]]. When fixing frontmatter, also check for and add this body section if related is non-empty. Always keep both in sync.
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.

kb-import is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (35 stars, last pushed 6d ago), licensed MIT. It adds 40 tokens to every session and 1,663 once invoked, about $0.0002 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.
