--- name: claims-a0766315b1a4 description: > Claims-based authorization for agents and operations. Grant, revoke, and verify permissions for secure multi-agent coordination. Use when: permission management, access control, secure operations, authorization checks. Skip when: open access, no security requirements, single-agent local work. --- # 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 ```bash npx claude-flow claims check --agent agent-123 --claim write ``` ### Grant Claim ```bash npx claude-flow claims grant --agent agent-123 --claim write --scope "/src/**" ``` ### Revoke Claim ```bash npx claude-flow claims revoke --agent agent-123 --claim write ``` ### List Claims ```bash 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 ## Cross-Host Work Claims (federation, v3.40.0+) Distinct from the *authorization* claims above: **work claims** coordinate *ownership of a task or resource* across agents, and now propagate across a cross-host federation so a claim made on one node is visible to the whole swarm. ### Runtime tools (local ledger) | Tool | Purpose | |------|---------| | `claims_claim` | Take ownership of an issue/resource (with optional TTL). | | `claims_release` | Give up a claim you hold. | | `claims_handoff` / `claims_accept-handoff` | Transfer a claim to another agent. | | `claims_steal` / `claims_mark-stealable` | Work-stealing for stalled claims. | | `claims_status` / `claims_list` | Inspect current ownership. | ### Federated (cross-host) Publish claim events into a federation room (`federation_bbs_publish`) so ownership converges across hosts. Message types: `ClaimIssued` / `ClaimReleased` / `ClaimHandoff` / `ClaimAck`. Rules: one owner per `resourceId`; first valid `ClaimIssued` wins (ties → earliest ts, then smallest `from`); `ClaimReleased` or expired TTL frees it; `ClaimHandoff` only from the current owner; a coordinator posts `ClaimAck` naming the authoritative owner. **Before shared work: claim, sync, and proceed only if you are the acknowledged owner.** When a claim must be both cross-host visible and runtime-enforced, mirror the two — publish the federation claim message *and* call `claims_claim`. See the `cross-host-federation` skill (ruflo-bbs-federation plugin) for the transport. ### Scoping a claim stream to a channel (ADR-386) By default every claim event lands in the shared swarm stream, where any relay member reads it. To keep a team's ownership ledger separate — or unreadable by the rest of the relay — publish claim messages into a channel instead: ``` npx ruflo federation channel --action create --name platform-team --visibility private npx ruflo federation channel --action grant --channel prv: --pubkey npx ruflo federation channel --action publish --channel prv: \ --type ClaimIssued --payload '{"resourceId":"repo/foo","ttlSeconds":7200}' npx ruflo federation channel --action read --channel prv: ``` Reduction rules are unchanged; only the audience changes. Two caveats before relying on it: a private channel hides content but **not metadata** (the relay still sees who published and when), and a claim nobody outside the channel can read cannot arbitrate against a claim made outside it. If ownership must be swarm-wide, keep it on the open stream. See the `open-federation` skill for channel mechanics. --- Source attribution: ruvnet Original project: https://github.com/ruvnet/ruflo/blob/e30d81b845815dbfaed2c4085790b23ed7654f91/.agents/skills/claims/SKILL.md License: MIT License information: https://opensource.org/license/mit Original upstream instructions; downloaded from Mega AI Hub. ## Upstream license notice MIT License Copyright (c) 2024-2026 ruvnet Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
