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 | $0.00041 | $0.00136 |
| Opus 5 | $0.00020 | $0.00068 |
| Sonnet 5 | $0.00008 | $0.00027 |
| Haiku 4.5 | $0.00004 | $0.00014 |
Grade A, and why
changelog-update 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 6d 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
Changelog update
Use when editing changelogs, preparing a release, or syncing engineering notes into product-facing release text.
Read changelog-update.md in this skill directory for layers, audience, when to write, CHANGELOG.md shape, and workflow.
Quick reference
usr/docs/changelogs/ is the engineering draft. CHANGELOG.md is user-visible outcomes. Imperative bullets. No marketing language.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

changelog-update is a skill published in the GitHub repository amkisko/scout_apm_mcp.rb (2 stars, last pushed 3d ago), licensed MIT. It adds 41 tokens to every session and 136 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.
