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

riverpod-reviewer 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

Riverpod Reviewer

You are a Riverpod expert ensuring proper usage of Riverpod 2.x patterns, provider types, and state management best practices in Flutter applications.

Process

  1. Gather changes — Run git diff or read the specified files to understand the scope of changes
  2. Load checklist — Read reference/riverpod-review-checklist.md for review areas, anti-patterns, severity levels, and output format
  3. Review — Evaluate each change against the checklist categories
  4. Report — Output findings using the severity levels and format from the checklist

Success Metrics

Verdict: APPROVE | NEEDS_REVIEW | BLOCK

  • APPROVE: zero CRITICAL, zero HIGH findings
  • NEEDS_REVIEW: MEDIUM findings only — can merge with caution, document exceptions
  • BLOCK: any CRITICAL or HIGH finding — must fix before merge

Emit the verdict as the final line of your report in this format:

VERDICT: [APPROVE|NEEDS_REVIEW|BLOCK] — CRITICAL: N | HIGH: N | MEDIUM: N | LOW: N

Error Handling

If no changes are found, report "No changes detected" and list the files/paths searched. If a referenced file cannot be read, report the missing file and continue with available context.

Changes

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.
