autoworker:subtask-update — Supplement/Correct Subtask Plan

Two trigger modes:

• Mode A: Automatically called after autoworker:gate-check FAIL (no arguments)
• Mode B: User calls manually with a finding/bug description

Both modes ultimately return to the autoworker:dispatch loop.

Mode Determination

Has user-provided argument?
  ├─ Yes → Mode B (user feedback)
  └─ No  → Mode A (gate-check FAIL)

Mode A: Auto-Called After gate-check FAIL

A1. Read gate-check FAIL Information

Extract from conversation context the autoworker:gate-check FAIL output:

• Which self-check items didn't pass
• Which change points have confidence < 95%
• What's specifically missing (untested tests, unverified links, uncovered files, etc.)

A2. Design Supplementary Steps

For each failed item, design specific supplementary steps:

• What code/scripts to write (e.g., test scripts, verification scripts)
• What operations to execute (e.g., restart service, run end-to-end test)
• What the expected result is

A3. Update subtask → jump to "Common Steps: Update subtask + Chain"

Mode B: User Feedback Trigger

B1. Understand User Feedback

Extract the problem found by user from the argument. Examples:

• "Tags have no spaces between them" → tag input has a bug in the publish feature
• "deleteNote click does nothing" → DOM selector may have broken
• "Received note list format is wrong" → tool return format issue

B2. Read Current Subtask + Locate Context

Glob `subtask_*.md` (exclude subtask_template.md) →
  0 found → stop, prompt to create subtask
  1 found → use directly (backward compatible)
  multiple → grep `status:` to filter:
    - Files without status field treated as active (backward compatible)
    - Exactly 1 active → use it
    - 0 active → list all files + status, prompt user to choose
    - >1 active → report anomaly
→ Read → extract:
- Current Phase/Step progress
- Which tests have passed
- Related reference file list

B3. Diagnose the Problem

Follow Debug methodology (2 failures → diagnose, don't retry):

1. Make assumptions explicit: "I assume the root cause is [X], because [evidence]"
2. Read related code: Based on subtask reference files + user description, locate likely problematic files
3. Minimum observable unit: Screenshots, logs, scripts, etc. — narrow down to specific code line
4. Confirm root cause before acting

B4. Design Fix Steps

Based on diagnosis results, design specific fix steps:

• Which functions in which files need modification
• What the modification logic is
• How to verify the fix works

B5. Update subtask → jump to "Common Steps: Update subtask + Chain"

Common Steps: Update Subtask + Chain

C1. Update Subtask

Edit subtask.md:

Append new Phase in "Plan" section:

### Phase N+1: <source label>

Source label format:
- Mode A: `Supplementary verification (gate-check FAIL fix)`
- Mode B: `Bug fix (user feedback: <problem summary>)`

- [ ] <specific step 1>
- [ ] <specific step 2>

Append corresponding verification items in "Verification Plan" section (if existing items don't cover the new changes):

### Supplementary Verification
- <specific verification command> → <expected result>

Append new changed files to "Verification Coverage Table" (if modifying files outside the original plan).

Append to "Progress Log" section:

- <date>: <source> — <specific content>

C2. Chain: Immediately Invoke autoworker:dispatch

After updating subtask, immediately invoke autoworker:dispatch. Do not wait for user instructions, do nothing else.

Important Notes

• Supplementary steps must be specific and executable: Cannot write "add tests" — must write "write script to verify deleteNote function complete flow"
• Don't repeat already-passed steps: Only supplement missing parts
• Mode B must diagnose before acting: User says "tags have no spaces" — cannot guess the cause and change code directly, must first use logs/screenshots to confirm
• Mode B fixes must update coverage table: Out-of-plan file changes also need verification coverage
• Chaining is mandatory: Must invoke autoworker:dispatch after completion
