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 | $0.00035 | $0.00253 |
| Opus 5 | $0.00017 | $0.00127 |
| Sonnet 5 | $0.00007 | $0.00051 |
| Haiku 4.5 | $0.00003 | $0.00025 |
Grade A, and why
report 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 4d 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

Reading it out
The metric is context per call — tokens carried into each API request. That is what a workspace can change. Cost per call is not: it moves when the user switches model, which has nothing to do with this plugin, and quoting it would take credit for something the plugin did not do.
new-read/call is the sharper number. It counts material entering the context for the first time —
files being opened. That is exactly what an index is supposed to make unnecessary.
What not to say
Do not present this as proof. The user's model, tasks, and Claude Code itself all changed over the same weeks. It is an observation on one repository, which is the honest and useful thing about it: it is their number, not a figure from someone's README.
If there is not enough history on both sides yet, say that plainly and stop. Do not reach for a comparison the data cannot support.
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.

report is a skill published in the GitHub repository ArcticFox2029/chamnan (4 stars, last pushed 6d ago), licensed MIT. It adds 35 tokens to every session and 253 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 2026-08-31.
