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 | $0.01266 | $0.01266 |
| Opus 5.5 | $0.00506 | $0.00506 |
| Sonnet 5.5 | $0.00253 | $0.00253 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
rosetta pr-review-bots.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 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.
How it starts
The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PR review bots (Copilot + CodeRabbit)
This is the rationale doc. For the runnable step-by-step procedure (list unresolved
threads, resolve them, re-check after a push), use the pr-review-gate skill
(.github/skills/pr-review-gate/SKILL.md) instead of re-deriving the gh commands here.
When a rosetta PR is marked Ready for Review (not while it is a draft), two
bots review it: copilot-pull-request-reviewer and coderabbitai. They surface
their findings through different GitHub mechanisms, so an agent that checks only
one signal will mis-read the state of the PR.
- CodeRabbit is a status check, not a findings gate. Its check turns green when
its review run finishes — green means "CodeRabbit is done looking," not "your
findings are addressed." Do not read a green CodeRabbit check as permission to merge.
It re-reviews on demand via an
@coderabbitai reviewPR comment. - Copilot is a requested reviewer. Its review lands as state
COMMENTED, neverCHANGES_REQUESTED. Sogh pr view N --json reviewDecisionwill not show it as blocking or pending the way a human "changes requested" review would — the findings are real but invisible to a decision-status check. - Bot reviews don't move
reviewDecision, but unresolved threads DO block the merge.mainis branch-protected: required status checks (test, both CodeQLAnalyze) plus required conversation resolution, withenforce_admins: false(an admin can still override the button, or merge viagh). Because both bots submitCOMMENTED(neverCHANGES_REQUESTED),gh pr view N --json reviewDecisionstays clean — the block surfaces asmergeStateStatus: BLOCKED, driven by the unresolved review threads, not by a review decision. SoreviewDecisionis not the signal to watch; an open bot thread is. Resolving every thread (below) is what clears the gate.
Wrapping a PR
Findings live in inline review comments, which gh pr view does not show. Read
them explicitly, then close the loop:
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.

rosetta pr-review-bots.instructions.md is an instructions file published in the GitHub repository tikoci/rosetta (51 stars, last pushed yesterday), licensed MIT. It adds 1,266 tokens to every session, about $0.0051 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
