That's a preference the model can forget under context pressure, get talked out of by a crafted input, or deprioritize mid-task — it isn't a control. As agent security matured through 2026, the field converged on one line: permission is infrastructure, not prompt. This kit gives you that infrastructure as five tiers, a manifest format, a tested enforcement hook, an audit trail, and a red-team checklist — without adopting a new runtime.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this kit does\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eDefines a \u003cstrong\u003efive-tier Permission Ladder\u003c\/strong\u003e (read_only → propose → auto_safe → human_approval → blocked) for classifying every tool call by what it actually does, not what the model says it's doing\u003c\/li\u003e\n  \u003cli\u003eShips a \u003cstrong\u003emanifest format\u003c\/strong\u003e (JSON Schema + worked YAML example) for declaring which tools and argument patterns fall into which tier, with default-deny built in\u003c\/li\u003e\n  \u003cli\u003eIncludes a \u003cstrong\u003etested reference enforcement hook\u003c\/strong\u003e for Claude Code's PreToolUse event — run through a 15-case test suite, including a real rule-ordering bug caught and fixed before shipping — plus a porting guide for LangChain, custom loops, and MCP clients\u003c\/li\u003e\n  \u003cli\u003eProvides \u003cstrong\u003eescalation templates\u003c\/strong\u003e for human-in-the-loop approval that bind every approval to one exact tool call, with async\/expiry handling and a list of the failure modes that quietly turn approval into a bypass\u003c\/li\u003e\n  \u003cli\u003eDefines a structured \u003cstrong\u003eaudit log schema\u003c\/strong\u003e — the record you hand a security review or a customer's compliance team\u003c\/li\u003e\n  \u003cli\u003eIncludes a \u003cstrong\u003ered-team checklist\u003c\/strong\u003e mapped to all ten OWASP Agentic Security Initiative categories, so you test the manifest against an adversarial input instead of trusting it on paper\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eBuilt for\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eAnyone shipping an agent that calls real tools — file writes, shell commands, API calls, payments, outbound messages, code execution\u003c\/li\u003e\n  \u003cli\u003eTeams that need a defensible, written answer to \"what stops this agent from doing something we didn't authorize\"\u003c\/li\u003e\n  \u003cli\u003eAgencies productizing agent builds for clients who ask about guardrails, permissions, or MCP security before signing off\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat's inside\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003epermission-ladder-framework.md\u003c\/strong\u003e — the full methodology: five tiers, default-deny, rule ordering, the tool-classification decision tree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003emanifest.schema.json\u003c\/strong\u003e + \u003cstrong\u003eexample-manifest.yaml\u003c\/strong\u003e — the permission manifest format and a complete, schema-valid worked example\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eaudit-log.schema.json\u003c\/strong\u003e — structured schema for every allow\/hold\/deny decision\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eescalation-templates.md\u003c\/strong\u003e — human-in-the-loop approval prompts, sync and async\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eowasp-asi-redteam-checklist.md\u003c\/strong\u003e — one concrete test per OWASP ASI Top 10 category\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ehooks\/pretooluse-permission-gate.py\u003c\/strong\u003e — the tested Claude Code enforcement hook\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ehooks\/generic-middleware.md\u003c\/strong\u003e — porting guide for LangChain\/LangGraph, custom agent loops, and MCP clients\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow you get it\u003c\/h3\u003e\n\u003cp\u003eYour full kit — every file, every schema, copy-paste ready — is hosted at \u003ca href=\"https:\/\/ukiyoprod.com\/pages\/agent-permission-ladder\"\u003eukiyoprod.com\/pages\/agent-permission-ladder\u003c\/a\u003e.
