codex-toolplan

codex-toolplan is a command for coding agents from aaditya0602/toolplan-mcp. It costs 0 tokens per session (188 once invoked), scanned B, original, MIT.

A command that sends a project idea to ToolPlan, a planning service that turns rough ideas into an initial development prompt.

In plain words
What is it for?
Use it to prepare a first prompt for a personal or production project, check current tools when web access is available, and review the result before building.
Why use it?
It helps turn an incomplete idea into a clearer plan with suggested technologies and development instructions before coding begins.

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 B, and why

codex-toolplan scanned grade B with 1 finding 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 3d 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

What it actually says

/toolplan for OpenAI Codex CLI — copy this file to ~/.codex/prompts/toolplan.md

Call the plan_project tool on the toolplan MCP server with:

  • idea: the text I passed after the command
  • grade: "industry" for production/business apps, otherwise "personal"; ask me if ambiguous.

Run the searches in the result's "Live Crosscheck" section if you have web access; append clearly-better findings under "Fresh findings (unverified)" with source links. Then show the final enriched prompt verbatim in a markdown block. Do not start building until I confirm or hand back an edited version.

If the server is missing, tell me to add to ~/.codex/config.toml:

[mcp_servers.toolplan]
command = "npx"
args = ["-y", "toolplan-mcp"]
Changes

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.
