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 | $0.00033 | $0.02563 |
| Opus 5 | $0.00016 | $0.01282 |
| Sonnet 5 | $0.00007 | $0.00513 |
| Haiku 4.5 | $0.00003 | $0.00256 |
Grade A, and why
update-nanoclaw 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 9d 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.
This is a copy
92% identical to update-claudeclaw — 30 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
About
Your NanoClaw fork drifts from upstream as you customize it. This skill pulls upstream changes into your install without losing your modifications.
Run /update-nanoclaw in Claude Code.
How it works
Preflight: checks for clean working tree (git status --porcelain). If upstream remote is missing, asks you for the URL (defaults to https://github.com/qwibitai/nanoclaw.git) and adds it. Detects the upstream branch name (main or master).
Backup: creates a timestamped backup branch and tag (backup/pre-update-<hash>-<timestamp>, pre-update-<hash>-<timestamp>) before touching anything. Safe to run multiple times.
Preview: runs git log and git diff against the merge base to show upstream changes since your last sync. Groups changed files into categories:
- Skills (
.claude/skills/): unlikely to conflict unless you edited an upstream skill - Source (
src/): may conflict if you modified the same files - Build/config (
package.json,tsconfig*.json,container/): review needed
Update paths (you pick one):
merge(default):git merge upstream/<branch>. Resolves all conflicts in one pass.cherry-pick:git cherry-pick <hashes>. Pull in only the commits you want.rebase:git rebase upstream/<branch>. Linear history, but conflicts resolve per-commit.abort: just view the changelog, change nothing.
Conflict preview: before merging, runs a dry-run (git merge --no-commit --no-ff) to show which files would conflict. You can still abort at this point.
Conflict resolution: opens only conflicted files, resolves the conflict markers, keeps your local customizations intact.
Validation: runs npm run build and npm test.
Breaking changes check: after validation, reads CHANGELOG.md for any [BREAKING] entries introduced by the update. If found, shows each breaking change and offers to run the recommended skill to migrate.
Rollback
The backup tag is printed at the end of each run:
git reset --hard pre-update-<hash>-<timestamp>
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.
