name: Bonk

# /bonk and @ask-bonk both trigger this workflow. The first word after the
# trigger picks a model alias from .github/bonk-models.json. Currently
# registered aliases (see that file for the source of truth):
#
#   /bonk <task>                         -> default model (currently opus)
#   /bonk opus <task>                    -> Claude Opus 4.7 (default)
#   /bonk kimi <task>                    -> Kimi K2.7 Code (cheap pass for tiny tasks)
#   @ask-bonk opus how would you do X?   -> Claude Opus 4.7
#
# Add new aliases by editing .github/bonk-models.json -- the resolver script
# only registers the selected alias in OPENCODE_CONFIG_CONTENT at runtime.

# Concurrency is at job level (below) rather than workflow level so it's only

# in the repo would enter the group and could evict in-flight runs from
# unrelated, non-matching comments.
