Execute the implementation plan by processing and executing all tasks defined in tasks.md.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## User Input

```text
$ARGUMENTS
```

You **MUST** consider the user input before proceeding (if not empty).

## Pre-Execution Checks

**Check for extension hooks (before implementation)**:
- Check if `.specify/extensions.yml` exists in the project root.
- If it exists, read it and look for entries under the `hooks.before_implement` key
- If the YAML cannot be parsed or is invalid, skip hook checking silently and continue normally
- Filter out hooks where `enabled` is explicitly `false`. Treat hooks without an `enabled` field as enabled by default.
- For each remaining hook, do **not** attempt to interpret or evaluate hook `condition` expressions:
  - If the hook has no `condition` field, or it is null/empty, treat the hook as executable
  - If the hook defines a non-empty `condition`, skip the hook and leave condition evaluation to the HookExecutor implementation
- When constructing slash commands from hook command names, replace dots (`.`) with hyphens (`-`). For example, `speckit.git.commit` → `/speckit-git-commit`.
- For each executable hook, output the following based on its `optional` flag:
  - **Optional hook** (`optional: true`):
    ```

How to install

The exact contents, by fingerprint

mdr add vizier-lab/vizier/speckit-implement@sha256:042a0415ce60a5b6

The line at the top of this page pins the label git:20260813.0d20dc4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
