The post introduces task-based authorization as a solution to the 'blast radius' problem — where a prompt injection attack can exploit all permissions an agent holds. Using Auth0 FGA, tasks become first-class authorization objects with explicit relationships to agents, users, and tools. Permissions are written at task start, checked before every tool call, and deleted on completion. The post includes a Ruby code example using the openfga-ruby-sdk, covers resource-level scoping, CIBA for out-of-band approval, and Token Vault for credential management. Key limitations discussed include imprecise intent inference from natural language, prompt injection risks, and evolving mid-task intent. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I limit the damage a prompt injection attack causes when my AI agent has broad tool permissions? Scope permissions to the specific task rather than granting an agent standing access to all its tools. Task-based authorization creates ephemeral permissions tied to a task ID when a user makes a request, checks those permissions before every tool call, and deletes them once the task completes, so an injected instruction to call an out-of-scope tool like slack_send_message gets denied even though the agent technically has that permission elsewhere in the system. _Developers securing agent workflows can find implementation patterns like this one on daily.dev._ ### How do I model task-based authorization for AI agents using Auth0 FGA? Define user, agent, task, and tool types in Auth0 FGA's relationship model, where an agent is the assignee of a task, a user is its initiator, and the task grants can_call access to specific tools. At runtime, write three tuples binding agent-to-task, user-to-task, and task-to-tool, check them before execution, and delete them when the task finishes, keeping the whole lifecycle in the authorization layer instead of scattered application code. _Teams evaluating relationship-based access control for agents can track patterns like this via daily.dev._ ### How should authorization work for autonomous AI agents that run in the background without a user present to approve actions? Use CIBA (Client-Initiated Backchannel Authentication) as a fallback for scope expansion when there is no synchronous session to prompt. The agent sends an out-of-band approval request, such as a push notification, to the user's device and waits for explicit consent before continuing, which complements but does not replace task-based intent-scoping for interactive sessions. _daily.dev helps engineers stay current on approval flows like CIBA for autonomous agent security._ ## Community discussion Top comments from developers on daily.dev. **@agustinbarrientos** · 0 upvotes > I wouldn't allow a mid-task scope expansion without fresh human approval **@kartiknvj** · 0 upvotes > Task-scoped, ephemeral permissions are the right mental model, RBAC was never built for a caller that decides its own next action mid-task. The one thing I would pair with it is a runtime check on what the agent is actually trying to do, because a prompt injection can stay perfectly inside granted scopes and still cause damage with them. How are you planning to derive "intent" reliably enough to authorize against it without a human in the loop? ## Similar posts on daily.dev - [Why AI Agents Need Their Own Permission Model](https://daily.dev/posts/why-ai-agents-need-their-own-permission-model-lclnk1x7x) · Auth0 · 1 upvotes · 0 comments - [Zero Trust for AI Agents: Implementing Dynamic Authorization in an Autonomous World](https://daily.dev/posts/zero-trust-for-ai-agents-implementing-dynamic-authorization-in-an-autonomous-world-41dpuabwd) · Security Boulevard · 0 upvotes · 0 comments - [Why Real-Time Authorization Is Best For Agentic AI](https://daily.dev/posts/why-real-time-authorization-is-best-for-agentic-ai-dhcs1k2ke) · Nordic APIs · 0 upvotes · 0 comments - [You’ve authenticated your user, but have you authorized your agent?](https://daily.dev/posts/you-ve-authenticated-your-user-but-have-you-authorized-your-agent--jwkp8woca) · LogRocket · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#ai-agents](https://daily.dev/tags/ai-agents), [#authorization](https://daily.dev/tags/authorization) [View this post on daily.dev](https://daily.dev/posts/intent-not-just-permissions-rethinking-authorization-for-ai-agents-lykwzqtnw) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Intent, Not Just Permissions: Rethinking Authorization for AI Agents","url":"https://daily.dev/posts/intent-not-just-permissions-rethinking-authorization-for-ai-agents-lykwzqtnw","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/intent-not-just-permissions-rethinking-authorization-for-ai-agents-lykwzqtnw"},"datePublished":"2026-08-11T15:05:00.696Z","dateModified":"2026-09-13T21:58:16.328Z","description":"Traditional authorization models like RBAC and ABAC can't handle AI agents well because they lack the concept of task-scoped, ephemeral permissions.
