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 | $0.00046 | $0.01483 |
| Opus 5 | $0.00023 | $0.00741 |
| Sonnet 5 | $0.00009 | $0.00297 |
| Haiku 4.5 | $0.00005 | $0.00148 |
Grade C, and why
update scanned grade C 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 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
If cancelled, clean up the temp dir (`rm -rf <TEMP_DIR>`) and stop. This is a copy
95% identical to update — 10 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 — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Update NanoClawbster
Pull upstream changes and merge them with the user's installation, preserving skills and customizations. Scripts live in .claude/skills/update/scripts/.
Principle: Handle everything automatically. Only pause for user confirmation before applying changes, or when merge conflicts need human judgment.
UX Note: Use AskUserQuestion for all user-facing questions.
1. Pre-flight
Check that the skills system is initialized:
test -d .nanoclawbster && echo "INITIALIZED" || echo "NOT_INITIALIZED"
If NOT_INITIALIZED: Run initSkillsSystem() first:
npx tsx -e "import { initNanoclawDir } from './skills-engine/init.js'; initNanoclawDir();"
Check for uncommitted git changes:
git status --porcelain
If there are uncommitted changes: Warn the user: "You have uncommitted changes. It's recommended to commit or stash them before updating. Continue anyway?" Use AskUserQuestion with options: "Continue anyway", "Abort (I'll commit first)". If they abort, stop here.
2. Fetch upstream
Run the fetch script:
./.claude/skills/update/scripts/fetch-upstream.sh
Parse the structured status block between <<< STATUS and STATUS >>> markers. Extract:
TEMP_DIR— path to extracted upstream filesREMOTE— which git remote was usedCURRENT_VERSION— version from localpackage.jsonNEW_VERSION— version from upstreampackage.jsonSTATUS— "success" or "error"
If STATUS=error: Show the error output and stop.
If CURRENT_VERSION equals NEW_VERSION: Tell the user they're already up to date. Ask if they want to force the update anyway (there may be non-version-bumped changes). If no, clean up the temp dir and stop.
3. Preview
Run the preview to show what will change:
npx tsx scripts/update-core.ts --json --preview-only <TEMP_DIR>
This outputs JSON with: currentVersion, newVersion, filesChanged, filesDeleted, conflictRisk, customPatchesAtRisk.
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.

hive-connect-repo
Register a repo with the server-side census sync: hive repo add writes the durable repo registry (the sync daemon picks it up on its next tick — no restart), private remotes authenticate via a token env var NAME (never a stored secret), and hivehealth(includecensushealth=true) verifies both that the sync daemon itself…

Use when the user explicitly asks for a SKILL to create a worktree. If the user does not mention "skill" or explicitly request skill invocation, do NOT trigger this. Only use when user says things like "use a skill to create a worktree" or "invoke the worktree skill". Creates isolated git worktrees with…
