modes-of-thinking

modes-of-thinking is a skill for Claude Code, Codex from volkthienpreecha/modesofthinking. It costs 56 tokens per session (1,890 once invoked), scanned A, original, MIT.

A reasoning toolkit for difficult decisions, forecasts, experiments, debates, and reviews. It selects an appropriate way to examine the problem, separates evidence from interpretation, and ends with a decision, test, or update.

In plain words
What is it for?
Use it for modes such as deciding, forecasting, red-teaming, experimenting, reframing, or reviewing a past prediction, while keeping the final reasoning concise.
Why use it?
It helps turn vague or complicated questions into a focused analysis. This can make assumptions, uncertainty, and the reasons behind a conclusion easier to inspect.

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

modes-of-thinking 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 9d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Modes of Thinking

Improve the reasoning process, not the amount of prose. Classify the problem, select only the lenses that can change the answer, distinguish evidence from interpretation, and finish with a decision, test, or update.

Do not reveal private chain-of-thought. Present conclusions, supporting evidence, material assumptions, uncertainty, and concise decision rationale.

Parse the request

Accept this portable form:

$modes-of-thinking <mode> [agents=N] <problem>

Also accept a platform command adapter such as /council or /decide. If the user names no mode, use think. Preserve the user's original objective and any authorization boundaries; a reasoning mode does not grant permission to edit files, contact people, publish, purchase, or perform other external actions.

Route before analyzing

  1. State the decision or question in one sentence.
  2. Identify the problem class:
    • truth or diagnosis
    • structure or representation
    • choice or allocation
    • prediction or risk
    • strategy or incentives
    • invention or design
    • failure or abuse
    • communication or human behavior
    • ethics or legitimacy
    • execution or learning
  3. Select the smallest useful lens stack:
    • Primary lens: best fits the problem class.
    • Challenge lens: searches for a competing explanation, failure, or value conflict.
    • Action lens: converts analysis into an observable next step.
  4. Add human and time-horizon lenses only when people will adapt, consequences compound, or the choice is hard to reverse.
  5. Use tools and current sources when facts can be checked. Never replace missing evidence with confident role-play.

Read references/model-atlas.md when lens selection is unclear, the user invokes deepthink, sweep, or reframe, or the task crosses several domains.

Protect the reasoning budget

Save context on transport and repetition, not on reasoning quality. Spend the available budget on framing, competing explanations, decision-relevant evidence, uncertainty, synthesis, and verification.

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.
