A skill that halts a search at the first option clearing a threshold you set beforehand, instead of comparing forever.

## What it does

The skill kicks in when option comparison or context gathering has no natural endpoint and could burn the whole turn budget. The agent first names the decision, the remaining tool, context and time budget, and whether the choice is reversible. Only then does it write concrete pass/fail criteria for good enough — the threshold comes before any evaluation.

Search runs sequentially. Each option is scored against the threshold alone, and full comparison matrices are skipped unless the decision was flagged as high-stakes or irreversible. The first option that clears every criterion gets picked right away, and the leftover budget goes into execution rather than re-ranking.

Failure has its own rule: if nothing clears the threshold after the pre-set cap, the skill keeps the threshold and reports that no adequate option exists. Only a criterion predeclared as non-load-bearing can be relaxed, and the relaxation gets recorded. Raising the bar after a failed search is off the table. There is also a guard against overuse — when one cheap lookup settles a fact, the skill says to just do the lookup. Correctness gates like tests and security checks stay out of scope, because those need the right answer, not a sufficient-looking one.

## Install

### Claude Code (native platform)

```

2. **Manually: put the files in place**
- File: `~/.claude/skills/thinking-bounded-rationality/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/thinking-bounded-rationality/

### Codex

## When to use it
- stop comparing once the first option already qualifies
- write pass/fail criteria before evaluating anything
- keep context gathering from eating the turn budget
- report that no option was adequate instead of moving the goalposts
- keep tests and security checks out of satisficing

## Example prompts
- I'm comparing three parsing libraries. Set an aspiration level and stop at the first one that clears it.
- This search is dragging on — apply thinking-bounded-rationality and state the budget.
- Nothing cleared the threshold after the cap. Say so and don't move the bar.

# Bounded Rationality

Under finite tool, context, and time budgets, stop at the first option that meets a predeclared aspiration level. Optimize only when the good-to-best gap is worth the remaining budget.

## When to Use

- Search or option comparison has no natural endpoint and could consume the turn budget.
- Multiple options would clear the requirement and further comparison has diminishing returns.
- The decision is reversible or low-stakes relative to more search.
- You are gathering context beyond what the decision needs to ship.

## When NOT to Use

- Irreversible or high-stakes choices (data loss, security, migrations, public commitments) where the good-to-best gap is material.
- Correctness gates: tests, security checks, and "did the fix work?" need the right answer, not a sufficient-looking one.
- One cheap lookup would settle the fact — do it; do not satisfice past it.
- The aspiration level cannot be stated — clarify the requirement first.

## Procedure

1. **State decision and budget.** Name the choice, residual tool/context/time budget, and reversibility.
2. **Set aspiration before searching.** Write concrete pass/fail criteria for "good enough." Do not evaluate until the threshold is explicit.
3. **Search sequentially.** Score options in encounter order against the threshold only. Skip full matrices unless step 1 marked high-stakes/irreversible.
4. **Stop at first adequate.** When an option clears every criterion, select it immediately.
5. **Handle search failure without moving the goalposts.** If nothing clears after the pre-set cap, preserve the threshold and report no adequate option. Relax only a criterion predeclared as non-load-bearing, record the relaxation, and resume within a new cap; never raise the bar after failure.
6. **Commit.** Record choice and residual uncertainty; spend remaining budget on execution, not re-ranking.
