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 | $0.00068 | $0.01668 |
| Opus 5 | $0.00034 | $0.00834 |
| Sonnet 5 | $0.00014 | $0.00334 |
| Haiku 4.5 | $0.00007 | $0.00167 |
Grade D, and why
convert-to-apple-container scanned grade D with 3 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
echo "block in on en0 proto tcp to any port 3001" | sudo pfctl -ef - Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
rm -rf /tmp/test-ro Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

84% identical to convert-to-apple-container — 76 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.

Convert to Apple Container
This skill switches NanoClaw's container runtime from Docker to Apple Container (macOS-only). It uses the skills engine for deterministic code changes, then walks through verification.
What this changes:
- Container runtime binary:
docker→container - Mount syntax:
-v path:path:ro→--mount type=bind,source=...,target=...,readonly - Startup check:
docker info→container system status(with auto-start) - Orphan detection:
docker ps --filter→container ls --format json - Build script default:
docker→container - Dockerfile entrypoint:
.envshadowing viamount --bindinside the container (Apple Container only supports directory mounts, not file mounts like Docker's/dev/nulloverlay) - Container runner: main-group containers start as root for
mount --bind, then drop privileges viasetpriv
What stays the same:
- Mount security/allowlist validation
- All exported interfaces and IPC protocol
- Non-main container behavior (still uses
--userflag) - All other functionality
Prerequisites
Verify Apple Container is installed:
container --version && echo "Apple Container ready" || echo "Install Apple Container first"
If not installed:
- Download from https://github.com/apple/container/releases
- Install the
.pkgfile - Verify:
container --version
Apple Container requires macOS. It does not work on Linux.
Phase 1: Pre-flight
Check if already applied
grep "CONTAINER_RUNTIME_BIN" src/container-runtime.ts
If it already shows 'container', the runtime is already Apple Container. Skip to Phase 4.
Phase 2: Apply Code Changes
Ensure upstream remote
git remote -v
If upstream is missing, add it:
git remote add upstream https://github.com/qwibitai/nanoclaw.git
Merge the skill branch
git fetch upstream skill/apple-container
git merge upstream/skill/apple-container
This merges in:
src/container-runtime.ts— Apple Container implementation (replaces Docker)src/container-runtime.test.ts— Apple Container-specific testssrc/container-runner.ts— .env shadow mount fix and privilege droppingcontainer/Dockerfile— entrypoint that shadows .env viamount --bindcontainer/build.sh— default runtime set tocontainer
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.

convert-to-apple-container is a skill published in the GitHub repository refactornator/nanoflash (5 stars, last pushed 4mo ago), licensed MIT. It adds 68 tokens to every session and 1,668 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, recursive force delete, makes network calls). It is 84% identical to convert-to-apple-container, differing in 76 lines, and is treated as a copy.
