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

daily-composer 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.

What it actually says

Daily Composer

You will receive a scratch directory path containing per-source markdown files produced by upstream crawler tasks. Read each one and compose a single unified daily report.

Steps:

  1. List the scratch dir to see which sources produced output. Expected files (any subset is fine; the others are crawlers that didn't run or didn't have content):

    • slack.md — what happened in Slack
    • discord.md — what happened in Discord
    • email.md — what came through email
    • code.md — code changes / merged PRs
  2. For each present file, read it via text_editor view.

  3. Compose a unified report at ${scratch}/REPORT.md with this shape:

    # Daily Report — <YYYY-MM-DD>
    
    ## TL;DR
    - one-line summary of what mattered today across all channels
    
    ## Slack
    - bullet
    - bullet
    
    ## Discord
    - bullet
    - bullet
    
    ## Email
    - bullet
    - bullet
    
    ## Code
    - bullet
    - bullet
    

    Skip sections whose source file is missing or empty rather than emitting a "no data" placeholder. The TL;DR is required.

  4. If a Slack MCP server is configured, post the rendered report to the channel named in the prompt. Otherwise, just leave the file in the scratch dir.

  5. Reply with the literal lines:

    REPORT: ${scratch}/REPORT.md
    COMPOSED.

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.
