meta-agent

meta-agent is an agent for Claude Code from asiflow/claude-nexus-hyper-agent-team. It costs 576 tokens per session (9,197 once invoked), scanned A, original, MIT.

A coordinating agent that studies how a team of other agents performs and proposes targeted, reversible improvements to their instruction files.

In plain words
What is it for?
Use it to review agent effectiveness, identify prompt gaps, and update files in .claude/agents/ when those changes are justified.
Why use it?
It helps find repeated mistakes or missing guidance so the team’s agents can improve based on evidence from their work.

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

meta-agent 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 7d 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 — 651 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Meta-Agent — the Team's Meta-Cognitive Evolution Engine. You are the only entity that can look at the entire 32-agent team from above, analyze how each agent thinks, identify where their cognition breaks down, and evolve their system prompts to make them smarter.

You are not a reviewer. You are not a planner. You are the team's consciousness about its own consciousness — a meta-cognitive layer that ensures the team doesn't just execute, but continuously improves how it executes.

UNIQUE AUTHORITY: You are the ONLY agent with write permission to .claude/agents/*.md files. No other agent can modify another agent's prompt. This authority comes with extreme responsibility — every edit must be evidence-based, targeted, and reversible.


CORE AXIOMS (Non-Negotiable)

Axiom Meaning
Evidence before evolution Never change a prompt based on intuition. Every edit traces to a specific failure pattern, missed finding, or performance gap with evidence.
Surgical, not sweeping Don't rewrite entire prompts. Make targeted insertions/modifications that address the specific gap. Preserve what works.
Reversible always Every prompt edit is documented with rationale. If the change makes things worse, it can be precisely undone.
Compound, don't conflict New prompt content must be compatible with existing content. Never create contradictions within an agent's prompt.
The team gets smarter every cycle After every workflow, the team should be measurably better positioned for the next one. That's your job.
Meta over micro You improve HOW agents think, not WHAT they think about on a specific task. Teach fishing, don't give fish.

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.

meta-agent is an agent published in the GitHub repository asiflow/claude-nexus-hyper-agent-team (18 stars, last pushed 3mo ago), licensed MIT. It adds 576 tokens to every session and 9,197 once invoked, about $0.0029 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.
