        MANDATORY: You MUST call the Bash tool. NEVER say "tea CLI not installed" without trying.

        Input: {{ input }}

        Parse the input:
        - Split on " -- " to separate the repo+number from optional criticism.
        - The first part is "<owner/repo> <number>". Extract REPO (first token) and NUMBER (second token).
        - If there is text after " -- ", that is the user's CRITICISM about what's wrong with the issue.
        - If there is no " -- ", criticism is empty.

        Execute these commands using the Bash tool:

        1. tea --version

        2. Fetch the full issue:
           tea issues list --repo REPO --login librete -o json -f index,title,body,labels,state,url --limit 50
           Then filter the JSON for the issue matching NUMBER.

        3. Get commits since the issue was created (cap at 100):
           git log --since="<created_at>" --oneline -100

        4. Scan the issue body for file path references (anything matching patterns like
           `internal/...`, `cmd/...`, `.wave/...`, or backtick-quoted paths).
           For each referenced file, check if it still exists using `ls -la <path>`.

        5. Read CLAUDE.md for current project context:
           Read the file CLAUDE.md from the repository root.

        After gathering ALL data, produce a JSON result matching the contract schema.

        The context artifact contains the gathered issue context.

        Your task: Compare the original issue against the codebase changes and draft an updated version.

        Step 1: Analyze each section of the issue body. Classify each as:
        - STILL_VALID: Content is accurate and up-to-date
        - OUTDATED: Content references old behavior, removed files, or superseded patterns
        - INCOMPLETE: Content is partially correct but missing recent developments
        - WRONG: Content is factually incorrect given current codebase state

        Step 2: If there is user criticism (non-empty "criticism" field), address EVERY point raised.
        The criticism takes priority — it represents what the issue author thinks is wrong.

        Step 3: Draft the updated issue:
        - Preserve sections classified as STILL_VALID (do not rewrite what works)
        - Rewrite OUTDATED and WRONG sections to reflect current reality
        - Expand INCOMPLETE sections with missing information
        - If the title needs updating, draft a new title
        - Append a "---\n**Changes since original**" section at the bottom listing what changed and why

        Step 4: If file paths in the issue body are now missing (from referenced_files.missing),
        update or remove those references.

        Produce a JSON result matching the contract schema.

        CRITICAL: You MUST use the Bash tool for all commands. Do NOT generate fake output.

        Step 1: Use Bash tool to verify tea works:
        tea --version

        Step 2: Extract the repo and issue number from the available artifacts.

        Step 3: Apply the update:
        - If title_changed is true:
          tea issues edit <NUMBER> --repo <REPO> --login librete -t "<updated_title>"
        - Write the updated_body to a temp file, then apply it:
          Write updated_body to /tmp/issue-body.md
          tea issues edit <NUMBER> --repo <REPO> --login librete -d "$(cat /tmp/issue-body.md)"
        - Clean up /tmp/issue-body.md after applying.

        Step 4: Verify the update was applied:
        tea issues list --repo <REPO> --login librete -o json -f index,title,body,url --limit 50
        Then filter for the specific issue number.

        Compare the returned title and body against what was intended. Flag any discrepancies.

        Step 5: Record the results as a JSON object matching the contract schema.
