8eyes

8eyes is a skill for Claude Code from AgentBuildersApp/eight-eyes. It costs 15 tokens per session (1,655 once invoked), scanned A, original, MIT.

A code-review process that assigns eight separate reviewer roles to examine a change from different angles, including correctness, tests, security, performance, accessibility, documentation, and final integration.

In plain words
What is it for?
It helps perform adversarial code review, assess test coverage and edge cases, check vulnerabilities and speed, review accessibility and documentation, and verify the finished change.
Why use it?
Separate review perspectives can expose assumptions, defects, security issues, and missing coverage that one reviewer may overlook.

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

8eyes 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.

/8eyes - Multi-Agent Code Review

Trigger: /8eyes [target] Version: 4.2.0 — Verifiable Enforcement (installed plugin version)

Overview

Eight constrained reviewer roles with hook-enforced isolation. Prevents AI reviewer consensus failure through architectural enforcement.

Roles

Role Focus GLM 5.1 Eligible? Kimi K2.6 Eligible?
Implementer Code correctness, logic YES (alt — opt-in) NO (default vendor stays)
Test Writer Test coverage, edge cases YES (alt — opt-in) NO (default vendor stays)
Skeptic Adversarial review, assumptions NO (MiniMax canonical Skeptic) NO (MiniMax canonical Skeptic)
Security Vulnerabilities, auth, secrets NO — HARD EXCLUSION NO — HARD EXCLUSION
Performance Bottlenecks, complexity NO (default vendor stays) NO (default vendor stays)
Accessibility WCAG compliance, UX NO (default vendor stays) NO (default vendor stays)
Docs Documentation completeness NO (default vendor stays) NO (default vendor stays)
Verifier Final sign-off, integration NO (default vendor stays) NO (default vendor stays)
Long-Context Reviewer (opt-in) Cross-file architectural review when target spans 5-15 files YES — GLM 200K context lane YES — Kimi long-horizon lane
Architect-alt (opt-in) Cross-module architectural reasoning, large-design review NO (default vendor stays) YES — Kimi long-context architect lane

Min-1-Eastern Requirement (VON-1408 P2)

When invoking /8eyes by default (no operator-supplied --role overrides), at least 1 of the 8 default reviewer roles MUST be filled by an Eastern model (Kimi, MiniMax, or GLM), unless the governance-locked hard exclusions apply (see below). This requirement is satisfied automatically because MiniMax already canonically fills the Skeptic role; the requirement only forces visible review when an operator attempts to override the default skeptic with a Western model.

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.
