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

channel-digest 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 13d 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

Given the comma-separated channel names provided in $ARGUMENTS (strip leading # and whitespace from each):

  1. Parse the argument into individual channel names. Strip leading # and whitespace from each name.

  2. For each channel: a. Use slack_search_channels to find the channel ID. b. Use slack_read_channel to read recent messages (use a limit of 50 messages per channel to keep things manageable). c. Summarize the key activity in that channel: main topics, decisions, questions, and notable messages.

  3. Present the digest in this format:

    *Channel Digest — <today's date>*
    
    *#channel-1*
    - Summary point 1
    - Summary point 2
    
    *#channel-2*
    - Summary point 1
    - Summary point 2
    
    ...
    
  4. For each channel, keep the summary to 3-5 bullet points maximum. Focus on what's actionable or noteworthy.

  5. If a channel has no recent activity, note that it's been quiet and mention when the last message was posted (if visible).

  6. If a channel name can't be found, let the user know and continue with the remaining channels.

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.
