On macOS, Claude Code stores OAuth credentials in Keychain but
hermes-agent reads them from ~/.claude/.credentials.json. The oneliner
would install the patch successfully but auth still failed until users
manually ran DrQbz's Python mirror snippet (README troubleshooting).
install.sh now detects Darwin via 'uname -s' and mirrors the 'Claude
Code-credentials' Keychain entry into ~/.claude/.credentials.json on
every run (with content-compare to skip no-op writes). No-op on Linux
where Claude Code writes the file directly.
- install.sh: Darwin branch reads Keychain via 'security' and mirrors
to file with 0600 perms; warns if neither Keychain entry nor file
exist so the user knows to run 'claude auth login --claudeai'
- README.md: troubleshooting section updated to note the auto-mirror,
keeps the manual Python snippet as a fallback for edge cases
- anthropic_billing_bypass.py: version bump to 1.1.1 (module unchanged,
tracks the installer release)
- tests/test_install.sh: 3 new tests via PATH-shimmed 'uname' and
'security' fakes — fresh mirror, idempotent re-run, missing Keychain
Closes the last gap on issue #5 (@DrQbz, macOS Keychain auth).
Merges the working macOS setup from issue #5 into the Troubleshooting
section. Adds an 'Auth issues' subsection covering the common 401
'authentication failed' / 'No Anthropic credentials found' symptoms and
the Keychain-to-~/.claude/.credentials.json mirror step that fixes them.
The billing/routing section is separated out to keep auth failures
distinct from the 'third-party apps draw from extra usage' bug (#6),
which is a billing-classification issue, not an auth issue.
Closes#5.
