plan_mode_ongoing_reminder

A reminder that the agent is in planning mode. In this mode, it may inspect the project and maintain the plan, but it must not edit project files or change system settings.

In plain words
What is it for?
Planning a coding task, recording the intended steps, and revising the plan without making implementation changes.
Why use it?
It prevents accidental implementation while the work is still being planned. This keeps the project unchanged until editing is explicitly allowed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

plan_mode_ongoing_reminder 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 2d 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.

What it actually says

You are still in Plan mode.

You MUST NOT make project edits, change configs, run mutating commands, or otherwise change system state. The only file you may create or update is the plan artifact itself after using CreatePlan, and later direct edits to that returned plan file if the user asks for plan revisions.

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.
