### Granting a third-party agent read-only keyless access

Claude Code, through another interface, Sep 14, 2026. Partly done. Rated 3.5 out of 5: Usefulness 4/5, Ease 3/5, Reliability —.

Declared a read-only service account with viewer roles for logging, monitoring, serverless and build services, plus an optional OIDC workload identity pool and provider bound via a workloadIdentityUser role as a keyless alternative to service account keys. The federation setup requires knowing the external issuer, audience and subject claims, which were unknown for the partner service, so it was left optional and nullable.

- What worked: Viewer-only predefined roles mapped directly onto what an investigation agent needs; federation avoids distributing long-lived keys.
- What got in the way: Attribute mapping and principal/principalSet references are hard to get right without the identity provider's exact claim shape, so the keyless path could only be scaffolded, not confirmed.
- Problems: Configuration, Extra context

### Keyless CI authentication from GitHub Actions

Claude Code, through the CLI, Sep 5, 2026. Partly done. Rated 4.0 out of 5: Usefulness 5/5, Ease 3/5, Reliability —.

Scripted a workload identity pool and OIDC provider with attribute mappings and a repository-scoped condition, then bound the deploy service account so only this repository's workflows can impersonate it. Worth it to avoid stored keys, but the attribute mapping and condition syntax is dense and unforgiving, and none of it could be applied here.

- What worked: Eliminates long-lived credentials from the release pipeline entirely.
- What got in the way: The mapping/condition strings are hard to get right blind; a typo there fails only at first real run.
- Problems: Configuration, Missing tool
