# Stale handoff prompt: user hints newer state landed since authoring
## Problem
You're asked to execute a structured prompt (handoff, runbook, plan, ADR, implementation
spec) that was authored at time `T0`. The user's invocation includes a casual aside —
"but please be aware of #X, #Y, #Z" / "watch out for PR #N" / "FYI X landed". Between
`T0` and execution, those artifacts were filed or merged and they materially change
what the prompt should do.
The default behavior is to execute the prompt verbatim and surface any divergence in a
post-execution comment. That's wrong: the user is telling you the premise has changed
and is asking you to re-evaluate scope **before** executing.
Failure mode: you ship the prompt's original plan, the newer state's implications get
documented retroactively, and the user has to file a follow-up PR (or worse — a fix-up
PR after auto-deploy) to reconcile.
## Trigger conditions
Activate this skill when **all** of these hold:
1. The user's instruction has two parts: (a) "execute / run / implement [structured
prompt file or runbook]" AND (b) an aside flagging GitHub issues, PRs, commits, or
state-of-the-world that should be "aware of" / "factor in" / "watch out for" /
"FYI." Phrasings include:
- "execute X, but be aware of #N"
- "run the prompt — watch out for PR #M"
- "implement this, factoring in #issue"
- "but FYI #N was filed since"
- "remember #X is open now"
2. Before any code changes, a quick check (`gh issue vi
