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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00171 | $0.03229 |
| Opus 5 | $0.00086 | $0.01614 |
| Sonnet 5 | $0.00034 | $0.00646 |
| Haiku 4.5 | $0.00017 | $0.00323 |
Grade A, and why
two-lens-review 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.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
two-lens-review (v1.2) — the review gate + the whole-codebase audit
ONE protocol, two SCOPES over the SAME factors:
- Diff scope — the repo's mandatory merge gate ("Don't merge a PR without
the two-lens review" — workspace
CLAUDE.md, "Things NOT to do"; PR #23 merged unreviewed with a critical path-traversal). 2+ differentiated-lens agents on the diff, disposition in the PR thread. - Whole-codebase scope — the periodic / pre-release AUDIT. A diff review and an audit scan DIFFERENT populations (fix-introduced-in-one-change vs existing code + cross-PR accumulation), so the audit is a SEPARATE pass, not a bigger PR review — but it runs the same factors, verify contract, and disposition.
The factors, the fill-in-the-slots lens briefs, the five hard requirements, the
escalation triggers, AND the whole-codebase fan-out orchestration are all
canonical in
.github/prompts/pr-review.prompt.md —
read it; fill from THAT file, never a paraphrase here (a copy here is the exact
two-copies-drift class Lens 2 hunts — when the prompt gains a factor or trigger, a
copy here silently lags). This skill owns only when to invoke each scope, how
to orchestrate, and the red-flag self-checks.
When to use
Diff scope:
- Before merging any PR (no exceptions — it's the gate, not a nicety; no size exemption — lens count can shrink, the gate can't).
- User says "review this branch/PR", "two-lens review", "is this ready to merge".
- After a fix round, to re-review the new head before merge.
Whole-codebase scope:
- User says "whole-codebase review" / "audit the repo"; a pre-release or milestone sweep; a periodic drift/design-debt pass.
- NOT the per-PR gate — that's the diff scope above.
Two agents MINIMUM (diff scope), lenses differentiated (a shared lens makes
their misses re-correlate); lens/finder count scales with blast radius (or tree
size). The quality lever is never the lens NAME — it's the change-specific
checklist filled into the <...> slots, and the FACTOR COVERAGE (no family
silently dropped).
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.

two-lens-review is a skill published in the GitHub repository IvanWng97/pixtuoid (475 stars, last pushed today), licensed MIT. It adds 171 tokens to every session and 3,229 once invoked, about $0.0009 per session on Opus 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.
