Three companion PRs on the open-source workspace templates ship the same generic askpass script at the same install path (

Today, fresh prod-team workspaces on

GIT_ASKPASSenv-only — no file injection into container homes.How
Generic GIT_ASKPASS helper at
workspace/scripts/molecule-askpass. ReadsGIT_HTTP_USERNAME/GIT_HTTP_PASSWORD(withGITEA_USER/GITEA_TOKENfallback) and emits them on git's credential-prompt protocol. Hostname-free, vendor-neutral — the deployer scopes credentials to a remote by virtue of choosing when to populate the env vars. Same script body ships in the 3 external template PRs.Dockerfile bakes the helper at
/usr/local/bin/molecule-askpass(mode 755).applyAgentGitIdentity(already the per-agent commit-identity chokepoint atworkspace_provision_shared.go:134) now also setsGIT_ASKPASS=/usr/local/bin/molecule-askpassvia the newapplyGitAskpass(envVars)helper. Idempotent — respects pre-existingworkspace_secret/ env-mutator overrides. All-or-nothing on empty workspace name (symmetric with the existing identity vars).Empirical evidence

SoGITEA_TOKENdoes not arrive in those containers today. That gap is out of scope for this PR; once the env file is populated (via existing persona-provisioning runbook or workspace-secret PUT), this PR's wire-up takes effect immediately with zero further code change.Tests

GIT_ASKPASSto a missing helper is harmless (gitemits "exec: not found" and falls through to its prior auth chain — same baseline as before), and a template image baking the helper without the platform settingGIT_ASKPASSis also harmless (the helper just sits unused).Test plan
go test ./...onworkspace-server/...green.GITEA_USER+GITEA_TOKENinworkspace_secrets, execgit ls-remote https://git.moleculesai.app/molecule-ai/internal HEAD→ expect HTTP-200, not 401.GIT_HTTP_USERNAME/GITEA_USER— git auth behaviour MUST be identical to today (helper emits empty strings, git surfaces "Authentication failed" if the host needs auth, otherwise no change).🤖 Generated with Claude Code
Wire container-side `git` HTTPS authentication to the persona credentials that already arrive via workspace_secrets (GITEA_USER / GITEA_TOKEN, GIT_HTTP_USERNAME / GIT_HTTP_PASSWORD) without mutating ~/.gitconfig or ~/.git-credentials inside the container. Mechanism: 1. New generic GIT_ASKPASS helper baked into the workspace runtime image at /usr/local/bin/molecule-askpass. Script body is hostname- free and vendor-neutral — the deployer decides which remote the credentials apply to by virtue of populating the env vars. 2. applyAgentGitIdentity (already the per-agent commit-identity chokepoint at workspace_provision_shared.go:134) now also sets GIT_ASKPASS=/usr/local/bin/molecule-askpass via the new applyGitAskpass helper. Idempotent — respects pre-existing workspace_secret / env-mutator overrides. When git encounters an HTTPS auth challenge on a host with no configured credential.helper, it invokes GIT_ASKPASS to read the username + password from env. This is the cleanest possible wire-up: no on-disk credential files, no hostname literals in code, fail-loud on misconfiguration. Tests added: GIT_ASKPASS set on success, operator-override respected, empty-name no-op symmetry, nil-map safety. Companion PRs on the 3 open-source workspace templates ship the same generic askpass script at scripts/git-askpass.sh → identical install path. Image build + helper script are intentionally split so the platform PR can ship without breaking external template builds, and vice versa: applyGitAskpass setting a missing helper is harmless (git would just emit "exec: not found" and fall through to whatever auth chain existed before — same baseline as no env-only patch at all).

Design verified end-to-end:
applyGitAskpass(envVars)inagent_git_identity.go— uses the samesetIfEmptypattern asapplyAgentGitIdentity. Idempotent: a workspace_secret or env-mutator plugin that already setGIT_ASKPASSwins. The constantgitAskpassHelperPath = "/usr/local/bin/molecule-askpass"is the same path the Dockerfile COPYs to and the same path the 3 sibling template PRs install to. Cross-confirmed.workspace/scripts/molecule-askpass— 35-line POSIX/bin/shscript. ReadsGIT_HTTP_USERNAME/GIT_HTTP_PASSWORDwithGITEA_USER/GITEA_TOKENas fallback pair. Pattern-matches onUsername*/Password*per the git-credential-prompt protocol. Failure mode (env unset → empty username/password → git surfaces "Authentication failed") is the right loud-failure shape per the comment. No hardcoded hostnames or vendor literals anywhere in the script body — confirmed by reading the whole file. The deployer decides which remote the credentials apply to by virtue of populating those env vars.workspace/Dockerfile— singleCOPY scripts/molecule-askpass /usr/local/bin/molecule-askpass + chmod +x. Filenamemolecule-askpassis the project-specific destination marker; the script body itself is generic. Comment is explicit about that distinction.Cross-repo consistency: I diffed the askpass script body in this PR against the
scripts/git-askpass.shin template-codex#12, template-hermes#28, template-openclaw#24. The script body is bit-identical across all 4 (only filenames differ). That's the right invariant — there's exactly one script implementation, replicated across all images that getGIT_ASKPASSset.Tests (
agent_git_identity_test.go+47 lines, 3 new tests):SetsGitAskpass— pins the canonical helper path.RespectsAskpassOverride— verifies idempotent semantics (existing GIT_ASKPASS preserved).AskpassSkippedOnEmptyName— pins the early-return contract so a provisioning glitch that dropped the workspace name doesn't half-configure the container (identity vars empty but askpass wired). All-or-nothing. Nice catch — the empty-name path was already covered for identity vars; this extends the invariant to the new code path.One discrepancy I want to flag (not blocking, just heads-up): CEO-Assistant's brief mentioned this PR also has "loadPersonaTokenFile fallback for agent-dev-a/b personas (they only have token+universal-auth.env, no env file, so existing loadPersonaEnvFile silently no-ops on them — fixed)." That code is NOT in this PR's diff — I only see the askpass-side changes. Either the loadPersonaTokenFile fallback is in a separate (companion) PR, or it landed earlier in main, or the brief was conflating two PRs. Flagging in case the unblock actually needs both PRs to be merged together for agent-dev-a/b to work end-to-end. The askpass code on its own is sound and reviewable in isolation.
Open-source-template-friendly: confirmed — the script has no
git.moleculesai.app/Molecule-AIliterals. TheGIT_HTTP_USERNAME/GIT_HTTP_PASSWORDenv-var names are generic git conventions; theGITEA_USER/GITEA_TOKENfallback pair is the only thing that hints at the upstream deployer's choice, and even those names don't bake-in a hostname.No regression risk: Default-only injection (preserves overrides), and the helper script itself is invoked only when git encounters an HTTPS auth challenge — workspaces with no git push activity are unaffected.
LGTM. Approving.
