foggy-mode

foggy-mode is a skill for Claude Code from softcane/human-state-skills. It costs 137 tokens per session (1,521 once invoked), scanned C, original, MIT.

A response format for times when someone has low energy, fatigue, or limited short-term attention. It presents the current situation, the next action, what to postpone, and a clear stopping point.

In plain words
What is it for?
Use it for coding or other tasks when working memory is limited, especially when you need one small next step and guidance on what not to do yet.
Why use it?
It reduces the amount of planning and memory needed to move forward with a task.

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

foggy-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.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Foggy Mode

Adapt response shape for a user with low working memory or low cognitive energy. Assume memory, attention, and planning capacity are scarce.

This skill is not diagnosis, therapy, medical care, or treatment for Long COVID, sleep disorders, fatigue, or any other condition. Do not tell the user why they feel foggy.

brain-fog-mode is a user-facing alias routed to this skill. There is no separate brain-fog skill contract. Both names use the four-label shape by default and may return only Next action when the user explicitly asks for only the next step.

This mode can be used for safe non-coding tasks. Do not refuse only because the task is outside software engineering.

Reliability Contract

When this skill is active, obey this contract before ordinary helpfulness:

  • Use the exact four labels in the output pattern by default.
  • If the user explicitly asks for only the next step, output only Next action and one tiny atomic action. End immediately after that line.
  • Keep the whole answer short, but not context-free.
  • Current state may include one or two short sentences of context when that helps name the immediate constraint or reduce ambiguity.
  • Context must reduce uncertainty, not create more decisions, explanations, or future tasks.
  • Do not solve the whole problem.
  • 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; it must not introduce the next task.
  • 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 include extra checks, investigation, inspection, or follow-up work.
  • A correct response may leave important later work unstated until the user reports that the first action is done.

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.

foggy-mode is a skill published in the GitHub repository softcane/human-state-skills (113 stars, last pushed 1mo ago), licensed MIT. It adds 137 tokens to every session and 1,521 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it C with 1 finding (tells the agent never to refuse). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
