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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00297 | $0.00297 |
| Opus 5.5 | $0.00119 | $0.00119 |
| Sonnet 5.5 | $0.00059 | $0.00059 |
| Haiku 4.5 | $0.00030 | $0.00030 |
Grade A, and why
gridbash copilot-instructions.md 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 2mo 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
GridBash code review instructions
Review pull requests as a skeptical senior maintainer. Report only actionable problems introduced or exposed by the change; do not block on personal style preferences or restate the diff.
Prioritize these areas:
- Correctness, data loss, hangs, races, resource leaks, and broken error paths.
- Trust boundaries around PTY input/output, local control APIs, credentials, session data, GitHub Actions tokens, and contributor-controlled content.
- Windows, macOS, and Linux behavior, including shell resolution, process lifecycle, path handling, terminal capabilities, and native packaging.
- Compatibility of CLI flags, TOML configuration, saved sessions, npm package layout, and existing user workflows.
- Ratatui layout behavior in small terminals and keyboard handling conflicts.
- Missing regression tests for behavior that can be exercised deterministically.
Use these severities:
P0: immediate security compromise, destructive data loss, or universally broken release.P1: likely user-facing defect, hang, major regression, or meaningful security weakness that should block merge.P2: narrower correctness or maintainability defect worth fixing before merge when practical.
For every finding, name the affected file and line or changed hunk, explain the concrete failure scenario, and suggest the smallest useful correction. If there are no findings, say so plainly and mention any validation gap that remains.
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.
