nanoflash: Skill for Claude Code

.claude/skills/update-nanoclaw/SKILL.md

update-nanoclaw is a skill for Claude Code from refactornator/nanoflash. It costs 33 tokens per session (2,563 once invoked), scanned A, a copy of update-claudeclaw, MIT.

A guided process for bringing changes from the original NanoClaw project into a customized copy. NanoClaw is the upstream project being adapted, and a fork is a separate copy with local changes.

In plain words
What is it for?
Use it to review and synchronize an existing NanoClaw fork with its upstream Git repository.
Why use it?
It helps compare upstream changes, create a backup, and choose between merging or selectively applying changes without losing local work.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; names the AskUserQuestion tool; mentions Claude Code.

This is refactornator/nanoflash's own configuration. It tells Claude Code how to work on nanoflash itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nanoflash configures →

Token cost

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.

Security

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.

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>

Files

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.

Changes

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.
