Summary

easyp-tech/easyp#241 removes the global --cfg flag and the EASYP_CFG variable. In their place, lint, breaking, generate, and validate-config each get their own --config, placed after the command name.

Both actions currently pass the config input as a global --cfg=…, in front of mod download and in front of the command. With an image built from that change, any workflow that sets config fails in the very first step, Download dependencies:

Incorrect Usage: flag provided but not defined: -cfg

Change

Both actions get a new step, Detect config flag placement. It runs only when config is set, and it calls <command> --help in the selected image:

Image	Help lists --config	lint/breaking get	mod download gets
v0.x, v1 nightlies ≤ 20261009.1	no	global --cfg=… (as before)	global --cfg=… (as before)
v1 builds with easyp#241	yes	<command> --config=…	nothing: v1 reads protobuf.mod/protobuf.lock, not the policy
config unset	—	nothing	nothing

Some implementation details:

• The help text is first captured into a variable and only then searched with grep. Piping straight into grep -q under pipefail could misfire on SIGPIPE.
• The existing --format fallback is kept. The command-local config flag is carried into both attempts.
• READMEs explain the placement and that, with v1, the input should point to a policy file (easyp.yaml / *.easyp.yaml).

Test plan

Tested locally with a small runner that executes the action.yml steps the way GitHub does. It substitutes inputs.*, github.workspace and steps.*.outputs.*, and runs each step with bash -eo pipefail.

Fixtures were real git repos with an origin, a main branch, and a feature commit. The commit adds a lint violation (BadName) and deletes a field. The config is named so that it cannot be discovered without the input: ci.yaml for v0, ci.easyp.yaml for v1.

Action	Image	Placement	Result
lint	v0.17.0	global	FIELD_LOWER_SNAKE_CASE annotation, exit 1 ✅
lint	v1.0.0-nightly.20261009.1	global	2 annotations, exit 1 ✅
lint	local build of easyp#241	command	2 annotations, exit 1 ✅
breaking	v0.17.0	global	field-deleted annotation, exit 1 ✅
breaking	v1.0.0-nightly.20261009.1	global	FIELD_NO_DELETE annotation, exit 1 ✅
breaking	local build of easyp#241	command	FIELD_NO_DELETE annotation, exit 1 ✅
lint (no config)	local build of easyp#241	none	discovers easyp.yaml, exit 1 with annotations ✅
old lint/action.yml	local build of easyp#241	—	fails in Download dependencies with a --cfg usage error ❌ (confirms the regression)

Breaking runs on Docker Desktop for macOS occasionally exited 2 with Repository does not exist in current directory. Both the nightly image and the new build hit this. It happens right after the host git fetch rewrites .git, so it is a file-sharing artifact of the local environment, not of this change. GitHub's Linux runners use direct bind mounts.

Merge after or together with easyp-tech/easyp#241. The change is safe to merge first, because older images keep the global form.
