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 | $0.00096 | $0.03354 |
| Opus 5 | $0.00048 | $0.01677 |
| Sonnet 5 | $0.00019 | $0.00671 |
| Haiku 4.5 | $0.00010 | $0.00335 |
Grade A, and why
update-changelog scanned grade A with 1 finding 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 345 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Update Starcat Changelog
Read ALL git commits from the main Starcat project since the last version tag, then update
CHANGELOG.md (English) and CHANGELOG-ZH.md (Chinese) in supports/starcat-pro/.

Step 0: Ask for Version Number (MANDATORY — Do This FIRST)
This is a blocking step. Before reading any git log or touching any file, you MUST know the target version number. If the user did not provide one in their invocation, immediately ask:
"Which version number should I use for this changelog entry? (e.g.,
1.2.0,1.1.1)"
Do NOT proceed to Step 1 until the user answers. Do NOT guess or assume a version number.
If the user's invocation already includes a version number (e.g., "update changelog for 1.2.0"),
validate that it matches X.Y.Z format. If it doesn't, ask the user to provide a valid format.
The version number must be in X.Y.Z format (semantic versioning) because release-direct.sh
requires this format.
Step 1: Determine Commit Range
# Latest tag
git tag --sort=-creatordate | head -1
# All commits since that tag (NO filtering, NO skip)
git log <latest-tag>..HEAD --oneline --no-merges
# Count
git log <latest-tag>..HEAD --oneline --no-merges | wc -l
If no tag exists, start from the first commit.
If there are 0 commits since the latest tag, stop and tell the user: "No new commits since . There's nothing to add to the changelog."
Step 2: Read EVERY Commit Message (Do NOT Skip Any)
# Full messages for ALL non-merge commits — every single one
git log <latest-tag>..HEAD --format="---COMMIT---%n%h%n%s%n%b" --no-merges
Critical rule: Read EVERY commit first. Then in Step 3a, filter out non-user-facing changes. Don't skip commits at read time — some commits with non-standard prefixes may still describe user-visible changes. The filtering happens AFTER reading, based on content.
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.

update-changelog is a skill published in the GitHub repository starcat-app/Starcat (159 stars, last pushed today), licensed MIT. It adds 96 tokens to every session and 3,354 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
