symphony-trello: Skill for Codex

Trello Workpad

Goals

• Keep exactly one current-card comment that starts with ## Codex Workpad.
• Preserve useful context across retries, rework, and later human review.
• Avoid noisy progress comments.
• Keep private host paths and unrelated local details out of Trello.

Required Sections

Use concise Markdown. Include sections that are relevant to the card:

• Plan
• Acceptance Criteria
• Progress
• Validation
• PR / Review
• Blockers
• Handoff

How To Update

Use the scoped Trello tool when it is available:

{
  "tool": "trello_upsert_workpad",
  "arguments": {
    "text": "## Codex Workpad\n\n..."
  }
}

Symphony scopes the tool to the current card. Do not include a card id.

Update the workpad:

• Before implementation with the plan and acceptance criteria.
• After reproducing a bug or capturing current behavior.
• After meaningful implementation progress.
• After validation.
• Before moving to Human Review, Blocked, Merging, or Done.
• When returning to work after review comments or a retry.

Content Rules

• Record evidence, not only intentions.
• Prefer short bullet points over long status narratives.
• Do not include secrets, API tokens, private board ids, account names, or unrelated host paths.
• For filesystem blockers, do not copy absolute host paths or per-card workspace locations into the workpad. Refer to them as "the requested path" or "the per-card workspace", explain that undeclared host paths are blocked by default, and point the operator to the allowed-host-path settings.
• If the tool fails because the existing workpad cannot be updated, treat the card as blocked instead of creating duplicate progress comments.

Stop Conditions

• trello_upsert_workpad is unavailable or disabled and the workflow requires a durable workpad for safe handoff.
• The only way to explain progress would expose secrets or unrelated internals.
