cross-modal-review

cross-modal-review is a skill for Claude Code, Codex from timurgaleev/memex. It costs 74 tokens per session (1,561 once invoked), scanned A, a copy of cross-modal-review, MIT.

A second-opinion review step that asks a different AI model to check work before it is finalized. It compares the work with the promises made by the original task.

In plain words
What is it for?
Use it for ad-hoc reviews of significant code changes, security-sensitive work, architecture decisions, refactors, API changes, or other work that needs an independent check.
Why use it?
It can catch problems that the first model missed, especially in large, architectural, or security-related changes. If a reviewer refuses, it switches to another model, while the user makes the final decision.

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

cross-modal-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 9d 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 — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cross-Modal Review

Convention: see conventions/cross-modal.yaml (via get_skill conventions/cross-modal) for the review pairs and refusal routing chain.

Relationship to memex eval: This skill is the manual mid-flow gate (one model reviews work product before commit, with refusal routing). The memex eval CLI is a sibling surface: it scores retrieval and skill behavior against documented fixtures before tests cement behavior. Use this skill for ad-hoc second opinions; use memex eval for the skillify quality gate. The two are complementary, not redundant.

Contract

This skill guarantees:

  • Work product is reviewed by a different model before finalizing.
  • The review is graded against the originating skill's Contract section (what was promised), not vibes.
  • Agreement and disagreement are reported transparently.
  • Refusal from one model triggers a silent switch to the next in chain.
  • The user always makes the final decision (user sovereignty).

When to invoke (v1.1 gating)

Invoke this skill when:

  • Significant code changes — any commit touching 5+ files or 100+ lines. Architecture decisions, refactors, API changes.
  • Security-sensitive changes — auth flows, brain-write trust boundaries, webhook transforms, cross-skill data passing.
  • Stuck or churning — 2+ iterations on the same problem without progress.
  • Pre-bulk-operation — before running batch enrichment, migrations, or bulk writes (see conventions/test-before-bulk.md via get_skill conventions/test-before-bulk).
  • Skill creation / modification — new or rewritten skills that affect operational behavior.
  • Brain-page quality concerns — when brain writes need validation against the originating skill's Contract.

Do NOT invoke for:

  • Simple memory writes or brain-page updates
  • Single-file typo fixes
  • Routine scheduled-job output or heartbeat operations
  • Git commit / push of already-reviewed work

Phases

  1. Capture the work product. The brain page, analysis, code diff, or decision to be reviewed.
  2. Load the Contract. Read the originating skill's Contract section (what was promised) — get_skill returns it.
  3. Spawn review model. Send the work + Contract to a different model. Use conventions/model-routing.md (via get_skill conventions/model-routing) for model selection — for brain-side passes that means the Bedrock tiers (Haiku = utility, Sonnet = synthesis); for a genuinely different model family, use a reviewer from the agent harness's own tooling.
  4. Grade. Model evaluates: did the output follow the Contract? Pass / fail with specific citations.
  5. Report. Present agreement / disagreement to the user. Never auto-apply the reviewer's suggestions.
