bet-on-it

bet-on-it is a skill for Claude Code, Codex from Lum1104/bet-on-it. It costs 23 tokens per session (486 once invoked), scanned A, original, MIT.

A debugging method for testing uncertain explanations with small, observable actions. It records what you expected, what happened, and whether the explanation still holds.

In plain words
What is it for?
Use it to investigate bugs, check why a change had an effect, and choose the next diagnostic step. It also helps decide whether to continue, revise, abandon, or undo an approach.
Why use it?
It reduces guesswork when several causes could explain a bug or behavior change. Each test gives you evidence without quietly changing your original prediction.

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

bet-on-it 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 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.

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 — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bet On It

Make each action earn or lose confidence. Never rewrite a prediction after its result.

Record the bet

When an action depends on an uncertain causal explanation, record this in working notes or commentary—not a repository file:

Hypothesis: <current causal explanation>
Expected observation: <specific result expected from the next action>
Expected change: <files, state, metric, or behavior; none for observation-only steps>
Disproof: <result that would make this hypothesis untenable>

Use observable signals. One bet may cover coupled steps. Skip bets for mechanical work or settled requirements.

Run the smallest discriminating step

Choose the cheapest safe step that separates plausible alternatives. Prefer read-only observation or temporary instrumentation before a persistent edit. Preserve baselines; separate unrelated changes.

Settle the bet

After the action, preserve the original prediction and append:

Observed: <actual result, including unexpected changes>
Verdict: matched | partially matched | failed | inconclusive
Next action: <continue, refine, abandon, revert, or gather a better signal>

Apply the verdicts consistently:

  • Matched: Expected results occurred and disproof did not. This raises confidence but does not prove causality when rivals predict the same result.
  • Partially matched: Some predictions held; narrow or revise the hypothesis.
  • Failed: A valid discriminator produced disproof or failed a required prediction. Abandon or revise.
  • Inconclusive: The step or measurement could not distinguish alternatives. Do not count it as support.

Revert speculative changes after a failed hypothesis when they lack independent justification. To keep one, state the new reason and test it under a new prediction.

Example

For a duplicate checkout request, Bet 1 predicts that instrumentation will show two client handler invocations; one invocation with two requests disproves it. Make no behavior change.

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.

bet-on-it is a skill published in the GitHub repository Lum1104/bet-on-it (5 stars, last pushed 1mo ago), licensed MIT. It adds 23 tokens to every session and 486 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
