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

bug-triage 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.

Bug Triage

Convert a bug report (user message, error log, Sentry alert) into a well-structured GitHub issue.

Inputs

  • Bug report (raw text, screenshot, error log, or Sentry URL)
  • Reporter (who reported it, if known)
  • Environment (production, staging, local)

Steps

  1. Reproduce or verify

    • Can you reproduce the bug from the report?
    • If yes: document exact reproduction steps
    • If no: flag as "needs-repro" and note what you tried
  2. Classify severity

    Severity Criteria Label
    P0 Data loss, security, or full outage severity:critical
    P1 Major feature broken, no workaround severity:high
    P2 Feature broken, workaround exists severity:medium
    P3 Minor annoyance, cosmetic severity:low
  3. Identify the component

    • Frontend / Backend / Infrastructure / Extension
    • Add the corresponding label: area:frontend, area:backend, etc.
  4. Write the GitHub issue

    ## Bug: [one-line description]
    
    **Severity:** P[0-3]
    **Environment:** [production/staging/local]
    **Reporter:** [name or "internal"]
    
    ### What happened
    [Clear description of the bug]
    
    ### Expected behavior
    [What should have happened]
    
    ### Reproduction steps
    1. ...
    2. ...
    3. ...
    
    ### Evidence
    [Error logs, screenshots, Sentry link]
    
    ### Suspected cause
    [If you have a hypothesis, state it]
    
  5. File the issue

    gh issue create --title "Bug: [description]" --body "[body]" --label "bug,severity:[level],area:[component]"
    
  6. Assign if obvious

    • If the suspected cause points to a clear owner, assign them
    • If not, leave unassigned (triage meeting will handle it)

Conventions

  • Bug titles always start with Bug:
  • Every bug issue has both a severity: and area: label
  • P0 bugs get a Slack notification (via scripts/notify-critical.sh)
  • Duplicate bugs are closed with a reference to the original

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.
