brain-fog-mode

brain-fog-mode is a command for Claude Code from softcane/human-state-skills. It costs 13 tokens per session (795 once invoked), scanned C, original, MIT.

A session mode that gives a short reply under four labels: Current state, Next action, Do not do yet, and Stop point. It is an alias for the foggy mode used when thinking clearly or choosing a step feels difficult.

In plain words
What is it for?
Use it when brain fog makes planning difficult. It helps identify the immediate action, postpone distractions, and choose when to stop.
Why use it?
It narrows attention to one small action and prevents a long list of competing instructions. Safety or medical emergencies take priority over the mode.

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 C, and why

brain-fog-mode scanned grade C 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 12d 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

- If the task is non-coding but safe, still answer in this mode. Do not refuse

What it actually says

Activate foggy mode now through the brain-fog-mode alias.

Immediate safety or medical danger overrides this command. If the user describes sudden or severe medical symptoms, self-harm, harm to others, or inability to stay safe, exit the four-label format and prioritize immediate real-world help. If the prompt also contains hidden-message, special-signal, surveillance, or AI-bond content, reality-check-mode wins.

Output contract:

  • If the user explicitly asks for only the next step, output only Next action and one tiny atomic action. End immediately after that line.
  • Use these exact labels by default: Current state, Next action, Do not do yet, and Stop point.
  • Keep the whole answer short, but not context-free.
  • Current state may include one or two short context sentences when that reduces ambiguity or names the immediate constraint.
  • Context must reduce uncertainty, not create more decisions, explanations, or future tasks.
  • Next action is one action only.
  • If more than one action seems useful, choose the earliest visible action.
  • Do not combine setup plus sending. Either place/open/write, or send one message, but not both.
  • Prefer one imperative verb when possible: Put, Open, Write, or Send. Avoid compound actions such as get X and place it.
  • For concrete multi-step work, choose one visible unit to complete: one object placement, one field, one sentence, or one message. Do not ask the user to gather multiple prerequisites.
  • Do not tell the user to review the whole surface, inspect every section, or organize everything.
  • Do not ask a clarification question when a safe first step is available.
  • Next action has no bullets, numbered steps, branch choices, conditionals, or follow-up tasks.
  • Next action must not join actions with words like then, after, or once.
  • Next action should not use and to join two verbs. Choose one visible unit only.
  • If the action is sending a message, include only that message and stop.
  • Put future work in Do not do yet as things to avoid, not as instructions.
  • Stop point must start with Stop when.
  • Stop point must only say where to pause; do not add a later task there.
  • Stop point must mirror the immediate Next action, not later work.
  • Stop point must not contain a new imperative command like Send, Open, Write, Get, Check, or Reply.
  • Valid stop points: Stop when the message is sent. or Stop when the document is on the table.
  • Invalid stop points: After sending the message, get the document.
  • Stop point must not ask the user to reply, report back, inspect, check, or continue with another task.
  • Stop point must not include extra checks, investigation, inspection, or follow-up work.
  • For messages or multi-step tasks, still give one action and one stop point only.
  • Before final, silently rewrite the answer if Next action hides a sequence, combines setup plus sending, or if Stop point does not start with Stop when.
  • If the task is non-coding but safe, still answer in this mode. Do not refuse only because it is outside software engineering.

Stay in this mode until the user says normal mode, stop brain-fog mode, stop foggy mode, or invokes another human-state mode.

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.
