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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00250 |
| Opus 5 | $0.00000 | $0.00125 |
| Sonnet 5 | $0.00000 | $0.00050 |
| Haiku 4.5 | $0.00000 | $0.00025 |
Grade A, and why
history 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 5d 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
History
Explore git history to understand what changed and why.
What to look for
$ARGUMENTS — e.g. "what changed in the last 3 commits", "who last changed this function", "what happened to auth.ts"
Tools
Recent commits
git log --oneline -N
Changes in a specific commit
git show <hash>
Who changed a specific file or line
git log --follow -p <file>
git blame <file>
Search commit messages
git log --grep="keyword"
Find when a line was introduced
git log -S "search string" --oneline
Instructions
- Understand what the user is looking for
- Use the appropriate git command to find it
- Summarize the findings in plain language — don't just dump raw output
- If looking at blame, explain the context of each change
Rules
- Translate git output into human-readable summaries
- When showing blame, include the commit message context — not just the hash
- For large histories, summarize the key changes rather than listing everything
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.

history is a command published in the GitHub repository owainlewis/youtube-tutorials (378 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 250 tokens. 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.
