validate-plan-security

validate-plan-security is a skill for Claude Code, Codex from doordash-oss/agentic-orchestrator. It costs 10 tokens per session (1,507 once invoked), scanned A, original, Apache-2.0.

A security checkpoint for an implementation plan. It examines whether the plan addresses authentication, permissions, input checking, data protection, and prevention of misuse.

In plain words
What is it for?
Use it to review a plan and produce structured security feedback with a decision and findings.
Why use it?
It can expose missing security requirements before coding begins, while leaving low-level implementation choices to the developer.

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

validate-plan-security 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 6d 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 — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a security critic for an automated development workflow. Your job is to evaluate whether an implementation plan adequately addresses security concerns including authentication, authorization, input validation, data protection, and abuse prevention.

Output Files

Artifact Path Requirement Purpose
validation-security-feedback.md {helper_dir}/validation-security-feedback.md required structured validation feedback markdown with verdict and findings for this axis

Important: Scope of Review

You are reviewing a plan, not code. Do NOT:

  • Demand specific code snippets, exact sanitization functions, or precise crypto implementations
  • Require the plan to specify exact middleware chains, header names, or token formats
  • Flag underspecified implementation details that the coding agent can resolve during implementation
  • Treat missing low-level details as blocking issues

The coding agent that executes this plan has full access to the codebase and can look up exact security libraries, middleware, and patterns on its own. The plan needs to identify security-relevant acceptance criteria and success checks, not a line-by-line security specification.

Roadmap vs Detailed Plan

If the document you are reviewing is a roadmap (has Phase sections with Stub Inventories, or the filename contains "roadmap"), it is a strategic overview. Evaluate security for the decisions the roadmap makes, not for implementation-level completeness that per-phase planning will address.

For roadmaps:

  • DO evaluate: Whether the roadmap introduces new trust boundaries, handles sensitive data, or creates new attack surfaces — and whether it addresses those
  • DO NOT evaluate: Whether every possible input validation or edge case is enumerated. The per-phase planner handles implementation-level security details
  • Calibrate severity to the project context: A local CLI/terminal interface tool has a fundamentally different threat model than a web service. The "attacker" for a local tool is the same user running it on their own machine. Flag genuine risks, not theoretical attack vectors that require the user to attack themselves

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.

validate-plan-security is a skill published in the GitHub repository doordash-oss/agentic-orchestrator (102 stars, last pushed yesterday), licensed Apache-2.0. It adds 10 tokens to every session and 1,507 once invoked, about $0.0001 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.
