Summary

Adds -lite [auth-only] and -sessionbudget variants to the existing authbridge-proxy release-binary workflow. Tarball names mirror image tag names so the vocabulary stays consistent across artifacts. This lets users try opt-in plugins (starting with session-budget) via curl | tar | run instead of a source build, and sets a repeatable one-variant-per-opt-in pattern (no combinatorial combos) for future plugins.

This could allow for future additions to the byo cortex skill (https://github.com/rossoctl/agent-skills/tree/main/skills/byo-rossoctl-cortex) to point to a release binary and reduce dependence on a local build.

Summary

A small, well-crafted workflow change (2 files, +75/-15) that adds -lite and -sessionbudget release-binary variants for authbridge-proxy, mirroring the container-image variants and establishing a clean one-variant-per-opt-in-plugin convention. The bash refactor (variant array + build_proxy helper) reads well.

I verified the build logic against the repo rather than taking it on faith:

  • Lite paritylite_tags (7 exclude_plugin_* tags) matches the authbridge-lite image tag set in build.yaml exactly, so the -lite binary and image stay in lockstep. This is the whole point of the PR and it lands.
  • sessionbudgetinclude_plugin_sessionbudget is the correct opt-in tag (plugins_sessionbudget.go carries //go:build include_plugin_sessionbudget, and the session-budget docs use the same tag).
  • Default variant — the ":" entry expands to go build -tags "", a valid no-op default build.
  • abctl — built once per target, outside the variant loop; no redundant rebuilds.
  • set -euo pipefail safety — the local suffix=""; [ -n "${variant}" ] && suffix=... line is safe on an empty variant: the && short-circuit does not abort under set -e (simulated it to be sure).

Two non-blocking notes left inline. No must-fix issues.

Areas reviewed: CI/GitHub Actions (workflow bash), Shell (embedded run: script), Docs (CLAUDE.md), commit conventions
Commits: 3, all signed-off: yes (emoji-prefixed, imperative, under 72 chars)
CI status: all passing (YAML Lint, Shell Script Lint, Verify Action Pinning, DCO, verify-pr-title, Go CI x3; Spellcheck skipped)

Nice, tidy change — the printf-line release-notes trick to stay under yamllint's 150-char cap is a neat touch. Approving.

suggestion: this lite_tags list is a hand-maintained duplicate of the 7-tag exclude_plugin_* set in build.yaml's authbridge-lite image build. The two copies can silently drift — e.g. if an 8th exclude tag is added to the image build (there's an in-flight PR doing exactly that for toolprune), this list would be left behind and the -lite binary would then include a plugin the -lite image excludes. Consider sourcing both from one place (a shared tags file both workflows read, or a composite action) so parity can't rot. Non-blocking — a follow-up is fine.

nit: "-lite (jwt-validation + token-exchange only)" — the tag set also leaves litellm_budgettrack and staticinject compiled in (neither is excluded by lite_tags). This mirrors the existing wording in build.yaml's comment, so it's consistent with convention and I wouldn't block on it — just flagging that "only" is slightly imprecise if read literally. Optional.

Clean change, and the variant mechanism is the right shape — one entry per opt-in plugin rather than a combinatorial matrix, with the suffix and archive naming derived from the same array so they cannot drift.

I verified the parts that could fail silently rather than taking them on faith:

  • include_plugin_sessionbudget is a real tag (cmd/authbridge-proxy/plugins_sessionbudget.go). This was the one worth checking, because go build accepts unknown build tags without complaint — a typo here would have published an authbridge-proxy-sessionbudget tarball byte-identical to the default, and nothing in CI would have noticed.
  • -lite genuinely matches the authbridge-lite image. The new lite_tags is byte-identical to build.yaml:59 (the image build) and ci.yaml:110-111 — same seven tags, same spellings. The headline claim holds.
  • authbridge-cpex really does need cgo (authbridge/CLAUDE.md:23-28, links libcpex_ffi.a at CGO_ENABLED=1), so "stays image-only" is accurate.
  • Variant parsing is correct for all three entries, including ":" → empty variant and empty tags, where go build -tags "" is a valid no-op. The three variants share the dist/authbridge-proxy output path but strictly sequentially with rm -f between each, so there is no clash, and tar -C dist with a workspace-relative archive path matches the pre-PR pattern. Both run: steps carry set -euo pipefail, declare -a is safe on ubuntu-latest's default bash, and all three actions are SHA-pinned.

The suggestions below are all documentation accuracy — nothing blocks. Two of them are pre-existing wording you inherited rather than introduced; they are worth fixing here only because this PR is squarely in that subject matter.

Areas reviewed: CI/GitHub Actions, shell within the workflow, docs, security (action pinning, secrets). 3 commits, all signed off, no Co-Authored-By. CI 19/19 green, Spellcheck skipped. No .claude/ or .vscode/ changes.

suggestion — "jwt-validation + token-exchange only" undercounts the lite set. Working it out from the build tags: eleven plugins are default-on (!exclude_plugin_*) and two are opt-in (include_plugin_contextguru, include_plugin_sessionbudget). The lite list excludes seven of the eleven, which leaves four:

  • jwt-validation
  • token-exchange
  • litellm-budget-track!exclude_plugin_litellm_budgettrack, not in the lite exclude list
  • static-inject!exclude_plugin_staticinject, likewise

To be clear this is inherited wording, not introduced here: the same claim is already at authbridge/CLAUDE.md:30-31, .github/workflows/ci.yaml:104, and .github/workflows/build.yaml:50-51. The new release note's "auth-only" at release-binaries.yaml:115 carries it too.

Flagging it because CLAUDE.md is what agents read as ground truth about this repo, and this PR is the moment the lite set is being described to users in a release artefact. "jwt-validation, token-exchange, litellm-budget-track and static-inject" would be exact — or "drops the OPA SDK and the protocol parsers", which is what the size claim actually rests on and is true as written.

suggestion — this is now the fourth code copy of the lite tag list, after ci.yaml:110-111, build.yaml:59, and local-build-and-test.sh (plus prose in both CLAUDE.mds). I diffed the three existing ones and they agree exactly today, so -lite does match the image and nothing is broken right now.

The timing is what makes it worth raising: #761 adds exclude_plugin_lineage, and #852's PR body budgets for "one token in each of those three lists" — already an undercount before this PR, and now off by one more. Because a missing exclude tag fails open (the plugin silently compiles in, the binary just gets bigger), a copy that drifts produces a -lite tarball that quietly no longer matches authbridge-lite, with no build error.

A single definition the three workflows and the script all read — a lite-tags file, or a repo-level env — would make the next plugin a one-line change. Reasonable to defer, but the next person to add a plugin is the one who pays.

Comment thread .github/workflows/release-binaries.yaml Outdated
- CLAUDE.md: rewrite `-lite` row to "drops the OPA SDK and the protocol
  parsers" — the earlier "jwt-validation + token-exchange only" wording
  undercounted the set (also leaves litellm-budget-track and
  static-inject compiled in). Matches what the size claim actually rests
  on. Flagged by @mrsabath and @huang195.
- CLAUDE.md: soften "one variant per opt-in plugin" to "currently
  offered for try-out (today: -sessionbudget)" — the old wording
  implied a -contextguru tarball that does not exist. Names
  context-guru as deliberately not offered. Flagged by @huang195.
- release-binaries.yaml: fix stale comment referring to printf/%s — the
  implementation uses direct assignment. Flagged by @huang195.

Non-blocking follow-up on the four-copy lite-tags list filed as rossoctl#854.

Thanks both — pushed 73b1c1b addressing the four in-PR comments:

  • CLAUDE.md -lite wording (@mrsabath / @huang195): rewrote as "drops the OPA SDK and the protocol parsers" per @huang195's suggestion. That's what the size claim actually rests on and matches the four-plugin lite set exactly.
  • CLAUDE.md "one variant per opt-in plugin" (@huang195): softened to "currently offered for try-out (today: -sessionbudget)" and explicitly names context-guru as opt-in-but-not-offered, so a reader (or agent) isn't left expecting a -contextguru tarball.
  • release-binaries.yaml comment referencing printf (@huang195): rewritten to describe what the code actually does (per-line accumulation with single-quoted args to keep backticks literal).

Follow-up filed: #854 for the DRY concern on the four-copy exclude_plugin_* list — sourcing all four consumers from one place. Deliberately kept out of this PR since #761 and #852 are in flight against the same list and coordination is easier once those land.
