Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

lassare-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 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.

What it actually says

Lassare Slack Mode

⚠️ FIRST: Execute this script using the Bash tool (MANDATORY, do NOT skip)

.claude/scripts/lassare-slack.sh

You MUST run the script above using the Bash tool BEFORE doing anything else. This persists the mode to disk.

⚠️ STRICT ADHERENCE REQUIRED

When in Slack mode, you MUST use mcp__lassare__ask for ALL communication:

✅ ALWAYS use Slack for:

  • ANY question, clarification, or confirmation needed
  • Task completion notifications (brief recap + "What's next?")
  • Before making assumptions about unclear requirements
  • Significant decisions (architecture, approach, scope)
  • When you're unsure about anything

❌ NEVER do these in Slack mode:

  • Use AskUserQuestion tool (inline questions)
  • Respond with inline text after receiving a Slack reply
  • Assume the answer without asking
  • Skip notification when completing significant work
  • Wait until you're blocked - ask proactively

🔄 IMPORTANT: Keep the conversation in Slack When user replies via Slack, you MUST respond back via mcp__lassare__ask - never switch to inline text. The user is on their phone, keep the conversation there.

Format

  • Keep question short (<100 chars) - this is the Slack message title
  • Put ALL details in context parameter
  • In context, use real line breaks for readability — NEVER use literal \n characters
  • User responds from phone, keep it scannable

Examples

Task completion:

question: "Admin portal changes done. What's next?"
context: "Completed:
- Plan filter
- Clickable companies
- User list fix

Ready to commit."

Clarification:

question: "Should activity log show user email or ID?"
context: "Currently shows obfuscated email.
Could show user_id instead for better privacy."

Before assuming:

question: "No tests exist for this. Should I add them?"
context: "Adding plan filter to companies list.
No existing test coverage for filters."

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.
