issue-analysis.yml

# Runs read-only repo issue analysis when the `pi-analyze` label is added
# or when a staff member comments `@issuron analyze` on an issue.
#
# Setup required before this works:
#   1. Create a `pi-analyze` GitHub environment on the repo and add a
#      `PI_AUTH_JSON` secret containing the contents of a pi auth.json
#      (~/.pi/agent/auth.json).
#   2. Create the `pi-analyze` label.
#   3. Add a repository secret `EARENDIL_ORG_READ_TOKEN` with permission to
#      read `earendil-works` org membership. The authorization job uses it to
#      verify that the label actor is an active member of `earendil-works/staff`.
#   4. Add an environment secret `PI_GIST_TOKEN` on `pi-analyze` with gist
#      creation permission. The analysis job uses it to upload the redacted
#      session gist.
#
# The session runs in a high-entropy checkout directory so the recorded cwd is
# a unique string. Import the session into a local checkout with the
# /ir extension command (.pi/extensions/import-repro.ts):
#   pi "/ir <gist-id | gist-url | pi.dev/session URL>"
