claims

claims is a skill for Claude Code, Codex from ruvnet/ruflo. It costs 53 tokens per session (407 once invoked), scanned A, original, MIT.

A permission system for agents and their operations. It lets you grant, revoke, and check claims such as reading files, writing files, running commands, using memory, or accessing the network.

In plain words
What is it for?
Use it to define scoped permissions, inspect an agent's claims, and apply different access levels to secure operations.
Why use it?
It limits what each agent can access or do, which helps prevent unnecessary permissions during coordinated work.

Part of the claude-flow plugin — 134 skills, 52 commands, 11 agents, 4 hooks shipped together

About the project

Ruflo is an execution and coordination layer for Claude Code and Codex that equips AI coding agents with tools, memory, control loops, sandboxes, and collaboration mechanisms. Developers use it to organize specialized agents into swarms, coordinate workflows, retain knowledge across sessions, and communicate across machines. The catalogue entries are Ruflo’s skills, commands, agents, hooks, and plugin components.

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

claims 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 yesterday.

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.

What it actually says

Claims Authorization Skill

Purpose

Claims-based authorization for secure agent operations and access control.

Claim Types

Claim Description
read Read file access
write Write file access
execute Command execution
spawn Agent spawning
memory Memory access
network Network access
admin Administrative operations

Commands

Check Claim

npx claude-flow claims check --agent agent-123 --claim write

Grant Claim

npx claude-flow claims grant --agent agent-123 --claim write --scope "/src/**"

Revoke Claim

npx claude-flow claims revoke --agent agent-123 --claim write

List Claims

npx claude-flow claims list --agent agent-123

Scope Patterns

Pattern Description
* All resources
/src/** All files in src
/config/*.toml TOML files in config
memory:patterns Patterns namespace

Security Levels

Level Claims
minimal read only
standard read, write, execute
elevated + spawn, memory
admin all claims

Best Practices

  1. Follow principle of least privilege
  2. Scope claims to specific resources
  3. Audit claim usage regularly
  4. Revoke claims when no longer needed

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.
