Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00048 | $0.01904 |
| Opus 5 | $0.00024 | $0.00952 |
| Sonnet 5 | $0.00010 | $0.00381 |
| Haiku 4.5 | $0.00005 | $0.00190 |
Grade A, and why
blocklet-updater scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 257 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Blocklet Updater
Bumps a blocklet project version and creates a release bundle.
Workflow
1. Version Bump (Smart Detection)
Check for project-specific version update scripts before falling back to blocklet version patch.
1.1 Detect Version Update Method
Check the following in priority order and use the first match:
| Priority | Detection | Command |
|---|---|---|
| 1 | Makefile has bump-version target |
make bump-version |
| 2 | package.json has bump-version script |
pnpm run bump-version |
| 3 | package.json has version script |
pnpm run version |
| 4 | lerna.json exists | lerna version patch --yes |
| 5 | None of the above | blocklet version patch (fallback) |
Detection commands:
# Priority 1: Check Makefile for bump-version target
if [ -f "Makefile" ] && grep -q "^bump-version:" Makefile 2>/dev/null; then
VERSION_CMD="make bump-version"
fi
# Priority 2: Check package.json for bump-version script
if [ -z "$VERSION_CMD" ] && [ -f "package.json" ]; then
if cat package.json | jq -e '.scripts["bump-version"]' > /dev/null 2>&1; then
VERSION_CMD="pnpm run bump-version"
fi
fi
# Priority 3: Check package.json for version script
if [ -z "$VERSION_CMD" ] && [ -f "package.json" ]; then
if cat package.json | jq -e '.scripts["version"]' > /dev/null 2>&1; then
VERSION_CMD="pnpm run version"
fi
fi
# Priority 4: Check for lerna.json
if [ -z "$VERSION_CMD" ] && [ -f "lerna.json" ]; then
VERSION_CMD="lerna version patch --yes"
fi
# Priority 5: Fallback to blocklet version
if [ -z "$VERSION_CMD" ]; then
VERSION_CMD="blocklet version patch"
fi
1.2 Execute Version Bump
Run the detected command:
$VERSION_CMD
Important: Project-specific scripts (like make bump-version) often:
- Update
versionfile - Auto-generate
CHANGELOG.mdentries - Update multiple package versions in monorepos
- Call additional tooling scripts
If fails → EXIT with error output.
What ships with it
2 files 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.

blocklet-updater is a skill published in the GitHub repository ArcBlock/agent-skills (5 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 1,904 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
