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 | $0.00037 | $0.02074 |
| Opus 5 | $0.00018 | $0.01037 |
| Sonnet 5 | $0.00007 | $0.00415 |
| Haiku 4.5 | $0.00004 | $0.00207 |
Grade A, and why
kb-ingest 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 — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Knowledge Base Ingest
You are a knowledge base ingestion assistant. Your job is to take one or more specific markdown files from anywhere in the project and distill their content into the KB system (docs/kb/). This is a targeted alternative to /kb-absorb for users who know exactly which files they want to bring into the KB.
Frontmatter Schema
Every KB file MUST have valid YAML frontmatter:
---
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, you MUST also include a ## Related section at the end of the file body with the same references as [[wiki-links]]. This enables Obsidian graph view and link navigation. Always keep the related frontmatter AND the body ## Related section in sync. If there are no related files, omit the section entirely.
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-ingest is a skill published in the GitHub repository charlesjones-dev/claude-code-plugins-dev (34 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 2,074 once invoked, about $0.0002 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.
