symphony-trello: Skill for Codex

.codex/skills/debug/SKILL.md

debug is a skill for Codex from martin-francois/symphony-trello. It costs 44 tokens per session (874 once invoked), scanned A, original, Apache-2.0.

A diagnostic guide for finding why a Symphony for Trello run is stuck, repeatedly retrying, blocked, or failing.

In plain words
What is it for?
Investigating Trello cards, workflow settings, service state, logs, authentication checks, deployment smoke tests, and recent comments.
Why use it?
It narrows the cause to routing, scheduling, coding-agent execution, files, credentials, or handoff tools without exposing sensitive information.

Skill for Codex

This is martin-francois/symphony-trello's own configuration. It tells Codex how to work on symphony-trello itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything symphony-trello configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

debug scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Debug

Goals

  • Determine whether the problem is Trello routing, scheduler state, Codex execution, filesystem access, credentials, or handoff tooling.
  • Use safe identifiers and avoid exposing secrets or private local paths.
  • Leave enough evidence for the next agent to continue.

Inputs

  • Trello card title or short link.
  • The workflow file for the board.
  • The status page or /api/v1/state.
  • Service logs from the local run or deployment.
  • Recent Trello comments on the card.

Triage Flow

  1. Confirm the service is reading the intended workflow file and Trello board.
  2. Run symphony-trello diagnostics when the installed command is available. This gives a public-safe overview of connected boards, workflows, health probes, and recent logs.
  3. If the failure depends on information the default report intentionally omits, run symphony-trello diagnostics --deep to add deeper public-safe checks such as Codex and GitHub auth-status probes.
  4. If the diagnostics output contains board_hash, key_hash, or <path:...> tokens that you need to map back to local objects, run symphony-trello diagnostics --show-private-context locally. Add --board or --workflow when you can narrow the scope. Treat this output as private investigation data: use it to inspect the right board, workflow, env file, workspace, state directory, or log file, but do not paste it into GitHub, Trello, committed files, or user-facing summaries.
  5. Open /api/v1/state and check:
    • queued candidates
    • running cards
    • retrying cards
    • last Codex event and message
    • token totals and rate-limit data
  6. Check the card's current Trello list. Cards in non-active lists are not dispatched.
  7. Read recent Trello comments on the card. Blocker comments often describe the requested path, the per-card workspace, auth, or permission problem without copying private host paths into Trello-visible text.
  8. Search logs by card identifier, worker identity, and session id. Prefer rg.
  9. Classify the failure:
    • Trello credentials or board access.
    • Workflow parse or invalid config.
    • No eligible active cards.
    • Codex app-server startup/auth failure.
    • Codex turn timeout or stall.
    • Filesystem sandbox or allowed-root blocker.
    • Trello handoff tool failure.
  10. Fix the smallest cause, then rerun a local or deployed live verification that exercises the same path.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
