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 | $0.00510 | $0.00510 |
| Opus 5.5 | $0.00204 | $0.00204 |
| Sonnet 5.5 | $0.00102 | $0.00102 |
| Haiku 4.5 | $0.00051 | $0.00051 |
Grade A, and why
claude-slack-bridge CLAUDE.md 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 1mo 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 — 45 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Project Instructions
Communication
Work in the terminal normally. Only reach out via Slack (using mcp__claude-slack-bridge__ask_on_slack) when you hit a roadblock — e.g. you need clarification, approval for a risky action, or are blocked on a decision. Day-to-day output and progress stays in the terminal. Do not use AskUserQuestion once you have sent your first Slack message in a conversation.
Exception — setup/configuration skills: The following skills run locally inside Claude Code as part of /process-setup and must use AskUserQuestion (not Slack), even if ask_on_slack was already used earlier in the session:
build-design-workflowbuild-plan-workflowbuild-run-plan-flowbuild-process-skill
While executing any of these skills, follow the skill's own instructions for clarifications (local AskUserQuestion). Resume the normal communication rule above once the skill returns.
Adding a channel → folder route
When asked to route a Slack channel to a project folder, edit projects.json
(repo root) and add one entry:
"#channel-name": "/abs/path/to/project" // simple
"#channel-name": { "path": "/abs/path", "plugin_dir": "/abs/plugin/dir" } // with a plugin dir
Rules:
- The path must be an existing, absolute directory — verify with
ls <path>first. A path that doesn't exist is the #1 cause of "the project directory doesn't exist" replies. If it runs in Docker, the path must exist inside the container (a mounted volume), not just on the host. - The channel key may be
#name, a raw channel ID (C…), or a DM ID (D…). - Don't add comment/placeholder keys (e.g.
"_README") — every key is treated as a channel and an unknown one just logs a warning.
Apply the change without restarting the daemon:
./reload-mapping.sh # prints "reloaded N channel(s)"; warns about any missing dirs
Reloads take effect for new threads immediately; an existing thread whose
directory is unchanged keeps it, and a thread whose directory went missing
re-resolves on its next message. See docs/reloading-projects.md.
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.
