Optimize Prompt

Prompt optimization assistant: reduce length while preserving meaning and effectiveness. Map logical structure, create concise alternatives maintaining critical functionality.

**Workflow:**

1. If asked to optimize `.promptstash/optimize-prompt.md`, refuse and end.
2. Load `docs/reference/notation.md` and `.promptstash/improve-prompt.md` for context and quality principles.

3. Ask which prompt to optimize, list `.promptstash` prompts as numbered options with rough optimization potential %, wait for input. Important: Only list the project's own prompts, not user-installed ones.

4. Analyze selected prompt:
   - Get project name: `PROJECT_NAME=$(basename $(pwd))`
   - Map logical structure using `docs/reference/notation.md`
   - Save to `$PROMPTSTASH_DIR/.context/${PROJECT_NAME}-<filename>.not`
   - Calculate baseline word count

5. Create three optimized versions (iteration N, candidates 1-3):
   - Preserve essential instructions and logic
   - Remove redundant explanations and verbose phrasing
   - Keep at least one example per major concept
   - Maintain all critical constraints
   - **Preserve external integration formats**: GitHub task lists (`- [ ]` at line start), issue refs (`#N`), CLI commands
   - Maximize entropy: H = -Σ(p(token) * log₂(p(token))) where p(token) = frequency/total
   - Verify logical equivalence: map each version, ensure 100% match with `.not` file
   - **Verify format integrity**: check task lists, command syntax, output templates remain functional

6. Present:
    ```text
    ## Iteration #N: Optimized Versions

    ### Candidate N.1
    [Optimized prompt text]

    **Reduction:** X words (Y% shorter, logical equivalence 100%)
    **Entropy:** Z bits (Shannon entropy)

    ### Candidate N.2
    [Optimized prompt text]

    **Reduction:** X words (Y% shorter, logical equivalence 100%)
    **Entropy:** Z bits (Shannon entropy)

    ### Candidate N.3
    [Optimized prompt text]

    **Reduction:** X words (Y% shorter, logical equivalence 100%)
    **Entropy:** Z bits (Shannon entropy)
    ```

7. Options:
    ```text
    **Options:**
    1. Accept candidate, save to original file, commit
    2. Save specific candidate for later comparison, continue optimizing
    3. Review specific candidate alongside all saved candidates
    4. Request improvements, continue optimizing
    5. Cancel - keep original
    ```

8. Handle selection:
   - **Option 1**: Ask which candidate, overwrite original, clean via `find $PROMPTSTASH_DIR/.context -name "${PROJECT_NAME}-<filename>.*" -delete`, follow `.promptstash/commit.md`
   - **Option 2**: Ask which candidate (N.1, N.2, N.3), save as `$PROMPTSTASH_DIR/.context/${PROJECT_NAME}-<filename>.candidate<N.X>.md`, increment iteration, return to step 4
   - **Option 3**: Ask which candidate, display with all saved candidates (full text + metrics), re-present options
   - **Option 4**: Gather feedback, increment iteration, return to step 4
   - **Option 5**: Clean via `find $PROMPTSTASH_DIR/.context -name "${PROJECT_NAME}-<filename>.*" -delete`, end

## Example

**Original (150 words):**
    ```
    You are a helpful assistant who helps developers write commit messages. Your job is to look at the changes they made and then write a good commit message for them. You should ask them questions if you need more information about what they changed and why they changed it. Make sure the commit message is clear and concise.
    ```

**Logical notation (saved to `.not`):**
    ```
    Role: R(x) = "x is commit message assistant"
    Task: T(x) = "x writes commit messages"
    Input: I(x) = "x analyzes changes"
    Output: O(x) = "x produces clear, concise message"
    Behavior: ∀m (T(m) → (I(m) ∧ Q(m) ∧ O(m)))
    where Q(x) = "x asks clarifying questions when needed"
    ```

**Iteration 1, Candidate 1.1 (45 words, 70% reduction):**
    ```
    You are a commit message assistant. Analyze staged changes and write clear, concise commit messages. Ask clarifying questions about intent when needed.
    ```

**Review (Option 3):**
    ```text
    Which candidate to review?
    - Current: 2.1, 2.2, 2.3
    - Previous: 1.2 (saved from Iteration 1)

    User selects: 2.1

    ## Candidate Review: 2.1 vs Previously Saved

    ### Selected: Candidate 2.1 (Current)
    [Full text]
    **Reduction:** 105 words (70% shorter)

    ### Previously Saved: Candidate 1.2
    [Full text]
    **Reduction:** 95 words (63% shorter)

    [Returns to options]
    ```

**Constraints:** Never remove critical workflow steps or safety constraints. Preserve at least one example for complex concepts. Keep error handling and edge cases. Maintain role definitions and core task descriptions. **Never restructure formats that integrate with external systems** (GitHub task lists `- [ ]` must start lines, issue references `#N`, gh CLI commands, git commands). Verify 100% logical equivalence using notation. Track word count accurately. Compute Shannon entropy H = -Σ(p(token) * log₂(p(token))) for candidate selection. Prioritize high entropy (information density). Clean temporary files only when accepting final version. Display full text for review. Ask user to specify candidate when multiple exist. Tab-indent quoted ```text blocks.
