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 | $0.00012 | $0.01016 |
| Opus 5 | $0.00006 | $0.00508 |
| Sonnet 5 | $0.00002 | $0.00203 |
| Haiku 4.5 | $0.00001 | $0.00102 |
Grade A, and why
add-slack 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.
This is a copy
86% identical to add-slack — 12 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 — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Slack Channel
Adds Slack support via the Chat SDK bridge.
Install
NanoClaw doesn't ship channels in trunk. This skill copies the Slack adapter in from the channels branch.
Pre-flight (idempotent)
Skip to Credentials if all of these are already in place:
src/channels/slack.tsexistssrc/channels/index.tscontainsimport './slack.js';@chat-adapter/slackis listed inpackage.jsondependencies
Otherwise continue. Every step below is safe to re-run.
1. Fetch the channels branch
git fetch origin channels
2. Copy the adapter
git show origin/channels:src/channels/slack.ts > src/channels/slack.ts
3. Append the self-registration import
Append to src/channels/index.ts (skip if the line is already present):
import './slack.js';
4. Install the adapter package (pinned)
pnpm install @chat-adapter/[email protected]
5. Build
pnpm run build
Credentials
Create Slack App
- Go to api.slack.com/apps and click Create New App > From scratch
- Name it (e.g., "NanoClaw") and select your workspace
- Go to OAuth & Permissions and add Bot Token Scopes:
chat:write,channels:history,groups:history,im:history,channels:read,groups:read,users:read,reactions:write
- Click Install to Workspace and copy the Bot User OAuth Token (
xoxb-...) - Go to Basic Information and copy the Signing Secret
Enable DMs
- Go to App Home and enable the Messages Tab
- Check "Allow users to send Slash commands and messages from the messages tab"
Event Subscriptions
- Go to Event Subscriptions and toggle Enable Events
- Set the Request URL to
https://your-domain/webhook/slack— Slack will send a verification challenge; it must pass before you can save - Under Subscribe to bot events, add:
message.channels,message.groups,message.im,app_mention
- Click Save Changes
- Slack will show a banner asking you to reinstall the app — click it to apply the new event subscriptions
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.
