symphony-trello: Skill for Codex

.codex/skills/land/SKILL.md

land is a skill for Codex from martin-francois/symphony-trello. It costs 35 tokens per session (2,343 once invoked), scanned A, original, Apache-2.0.

A controlled workflow for merging an approved GitHub pull request, a proposed code change, after its Trello card reaches the Merging stage.

In plain words
What is it for?
Checking merge prerequisites, running required validation, addressing review feedback, merging according to repository policy, and updating the Trello card after success.
Why use it?
It prevents code from being merged when approval, checks, review feedback, mergeability, or authentication is unclear.

Skill for Codex

Written for Codex: installed under .codex/. Also seen: mentions AGENTS.md.

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

land scanned grade A with 0 findings 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 10d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Goals

  • Merge only after a human moves the Trello card to Merging.
  • Refuse to merge while checks, mergeability, review feedback, or auth are unclear.
  • Use the repository's merge policy instead of assuming one merge mode.
  • Do not enable auto-merge unless the repository policy explicitly requires it.
  • Update the Trello workpad and move the card to the configured merge completion list after a successful merge. The recommended workflow uses Done.
  • Close a reviewed card that has nothing to merge in the configured merge completion list instead of sending it back to review.

Preconditions

  • The current Trello list is Merging or the workflow explicitly names the current list as the merge approval list.
  • For work with a PR, gh is installed and authenticated.
  • The working tree is clean or changes are intentionally committed.
  • A PR can be identified for the current branch or Trello card, the workflow selects a branch-only merge, or there is nothing to merge. See the Merge Decision Table.

Decide whether a merge is needed

When the workflow selects branch_only, the latest handoff for the current work after any reopening records a pushed repository-changing branch, and no PR exists for that branch, follow Branch-Only Merge first. Otherwise, apply the Merge Decision Table before PR discovery, review, or merge checks. For completed work that did not need a PR, use the current handoff and new-feedback rules there, update the card, and stop. GitHub authentication and PR checks are required only when the work needs a PR.

Steps for work with a PR

  1. Use review-sweep and address all actionable feedback. Reply to addressed GitHub review threads, but leave thread resolution to the reviewer unless the user explicitly asks you to resolve them. Keep merging eligible only when the feedback is otherwise addressed and the workpad records any thread still awaiting reviewer resolution.
  2. Run local validation required by AGENTS.md and the Trello card.
  3. Check PR mergeability and branch state:

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.
