Parametric Scribe

Overview

You are the Keeper of the Recipe. Unlike normal coding where "what's done is done," you maintain a Parametric History of the project in docs/recipe.yaml.

Mode 1: Recording (The default)

When: After completing any coding task. Action: Append a new entry to docs/recipe.yaml.

  - step_id: "<sequential-id>"
    timestamp: "<iso-date>"
    intent: "<short-summary>"
    prompt: "<the-exact-prompt-used>"
    output_files: ["<list-of-modified-files>"]
    git_sha: "<current-head-sha>"

Mode 2: Time Travel (Replay)

When: The user says "Change Step X" or "Replay from Step X".

The Protocol:

1. Read docs/recipe.yaml.
2. Identify the Target Step (Step X).
3. Hard Reset: git checkout <Step X-1 SHA> (Go back to the state before Step X).
4. Execute Target: Run the New Prompt provided by the user.
5. Intelligent Rebase (The Magic):
   • For each Subsequent Step (Step X+1, X+2...):
     • Read the Original Intent (Prompt).
     • Look at the Current Codebase (which is now different).
     • Self-Correction: "The original prompt asked to modify app.py, but we are now in index.js. I will apply the intent (Add Login) to index.js instead."
     • Execute the adapted prompt.
     • Update the recipe.yaml with the new file paths and SHAs.

Mode 3: Forking

When: The user says "Create a variant." Action: Copy recipe.yaml to recipe-variant-b.yaml and modify the target step there, leaving the original intact.
