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 | $0.00018 | $0.00552 |
| Opus 5 | $0.00009 | $0.00276 |
| Sonnet 5 | $0.00004 | $0.00110 |
| Haiku 4.5 | $0.00002 | $0.00055 |
Grade A, and why
install-extension scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Install Extension
Install a ClaudeClaw extension from GitHub.
Usage
/install slack
/install triage
Flow
1. Validate input
The argument is the extension short name (e.g., slack, triage). The full repo name is claudeclaw-<name>.
EXTENSION_NAME="${1}"
REPO="https://github.com/sbusso/claudeclaw-${EXTENSION_NAME}.git"
EXT_DIR="extensions/claudeclaw-${EXTENSION_NAME}"
2. Check if already installed
[ -d "$EXT_DIR" ] && echo "Extension claudeclaw-${EXTENSION_NAME} is already installed." && exit 0
If already installed, ask if the user wants to update instead (git pull + rebuild).
3. Clone the extension
mkdir -p extensions
git clone "$REPO" "$EXT_DIR"
4. Read manifest and install dependencies
cat "$EXT_DIR/manifest.json"
If manifest.json has a dependencies field, install them at the root:
cd "$(git rev-parse --show-toplevel)" && npm install <each dependency with version>
5. Compile the extension
cd "$EXT_DIR" && npx tsc
6. Run post-install hook
If manifest.json has hooks.postInstall:
chmod +x "$EXT_DIR/hooks/install.sh"
bash "$EXT_DIR/hooks/install.sh" "$(git rev-parse --show-toplevel)"
This copies skills, agents, and agent skills into the ClaudeClaw root.
7. Rebuild core
npm run build
8. Restart service
Detect OS and restart:
macOS:
SERVICE_NAME=$(launchctl list | grep claudeclaw | awk '{print $3}')
[ -n "$SERVICE_NAME" ] && launchctl kickstart -k "gui/$(id -u)/$SERVICE_NAME"
Linux:
systemctl --user restart claudeclaw
9. Verify
Print confirmation:
Extension claudeclaw-<name> installed successfully.
- Skills: <list from manifest>
- Type: <channel|extension>
- Restart: service restarted
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.

install-extension is a skill published in the GitHub repository sbusso/claudeclaw (193 stars, last pushed 24d ago), licensed MIT. It adds 18 tokens to every session and 552 once invoked, about $0.0001 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 2026-08-30.

hello
Sample knowledge-only skill demonstrating the SKILL.md layout.
artifact-deploy
One-click deploy a user's pre-built app/artifact into their OWN AWS account and get a global public HTTPS link (Vercel-like), with a default TTL and promote-to-persistent. Use when the user says "deploy this", "ship this demo", "give me a public link", "share this externally", or "deploy to AWS".
explain-for
Explain a topic, a piece of code, an error, or a design decision calibrated to one named audience — a 5-year-old, a 5th grader, a manager, a designer, a graduate student, a parent. Resolves who the explanation is for (from the request, or from what memory already records about that person), establishes the ground…

Handle due reminders — notify the user with natural language and mark them done.
agent-initialization
Initialize an Agent's settings from a user requirement by writing AGENTS.md, setting identity metadata, and installing only needed Skills.

What the chat right-panel session summary shows, what it costs, and how to make a session summarize well. Load when the user asks about the session summary panel, why a summary looks wrong or empty, or how to turn it on.
