agpair

agpair is a skill for Claude Code from logicrw/agpair. It costs 46 tokens per session (3,985 once invoked), scanned A, original, MIT.

A workflow for sending substantial coding tasks to external command-line agents and comparing their implementation ideas, reviews, fixes, or verification results.

In plain words
What is it for?
Use it for repository scans, refactoring, test fixes, alternative implementations, code reviews, mechanical edits, and smoke checks.
Why use it?
It provides additional independent attempts or evidence for work that spans multiple files or requires research, testing, or review.

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

agpair 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.

AGPair for Claude Code

IRON LAW: Non-trivial work requires an explicit routing budget. Use external AGPair lanes by default, but fan out only when each lane has a distinct role, scope, hypothesis, or verification value. Multiple grok-cli lanes are valid when they are not duplicate prompts.

Claude Code is the controller and verifier. AGPair is the durable external-agent control plane.

Default Route

Use AGPair before Claude Code native subagents for non-trivial implementation, refactor, test-fix, research, review, or multi-file work.

Actively outsource low-value, repetitive, time-consuming, or easily verifiable work through AGPair: repo scans, alternative reviews, focused test-fix attempts, multi-file mechanical edits, smoke checks, and implementation slices with clear acceptance criteria. For ordinary non-trivial work, start with a strong external lane: grok-cli and antigravity-cli are peer first choices. Use both when independent evidence, implementation contrast, or latency hedging is useful. It is acceptable to run several attempts from the same executor at once for parallel review, competing implementation approaches, or file-sliced work, but each attempt needs a distinct task id, role, prompt, or scope.

Prefer these external lanes:

  1. grok-cli and antigravity-cli as peer first choices for review, research, and implementation attempts.
  2. Additional grok-cli or antigravity-cli lanes when prompts, scopes, or acceptance criteria are distinct.
  3. codex when an AGPair-managed external Codex CLI worker is useful as a fallback or challenger executor.

codex is the AGPair-managed external Codex CLI worker for Claude Code controllers. It is the cross-controller fallback lane, not a Claude Code native subagent.

Do not request the AGPair-managed external claude-code executor by default; Claude Code already has native subagents and claude-code is suppressed for Claude Code controllers unless --allow-self-executor is explicitly justified.

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.
