Summary

secrets env and secrets exec now accept the store-backed .secrets.json shape that README.md, AGENTS.md, CLAUDE.md, and the bundled skills already document:

{
  "secrets": [
    {"name": "github_token", "env_var": "GITHUB_TOKEN"},
    {"name": "openai_key", "env_var": "OPENAI_API_KEY", "ttl": "30m"}
  ],
  "client_id": "my-project"
}

Previously that file failed, even when present in the working directory:

{
  "ok": false,
  "command": "secrets env",
  "error": {
    "message": "failed to find project config: project config: source cannot be empty",
    "code": "generic_error"
  }
}

Root cause

internal/project/config.go (added in c317381) only implemented a provider-backed schema requiring source/project/scope/ttl. Because Validate() was not mode-aware, it rejected any config without source.

env_var never appeared in any Go file in the repository's history, so the documented store-backed format was never implemented — secrets env could not have worked with the documented config. This is a docs/code divergence rather than a regression.

Changes

  • internal/project/config.go — add SecretMapping, ProjectConfig.Secrets, ProjectConfig.ClientID. Validate() dispatches on IsStoreBacked(), so source is only required for provider-backed configs. Adds duplicate env_var detection and per-entry TTL validation. The default output file becomes mode-specific: .env for store-backed (as documented), .env.local for provider-backed.
  • cmd/secrets/env.go — store-backed configs lease each secret over RPC and write .env at 0600. The file's TTL is the earliest lease expiry, so it never outlives the shortest-lived secret it contains. One shared TTL resolver drives both the dry-run preview and the real lease path, so --dry-run reports the TTL each secret will actually be leased with.
  • cmd/secrets/exec.go — injects leased secrets into the subprocess and revokes them on exit. Returns the child's exit code instead of calling os.Exit, which skipped deferred cleanup and leaked the run's leases whenever the wrapped command failed.
  • cmd/secrets/project_leases.go (new) — shared lease helpers. Secret values are deliberately excluded from the JSON envelope.
  • README.md — documents both schemas; corrects the secrets exec and secrets cleanup descriptions (including a cleanup --dry-run flag that does not exist; the real flags are --path/--watch/--interval).

Provider-backed behaviour is unchanged and its existing tests still pass.

Verification

  • go build ./..., go vet ./..., gofmt -s clean.
  • go test -race ./... passes under umask 0022, matching CI.
  • New coverage for: store-backed loading, validation errors, TTL precedence (entry vs config vs flag), lease-failure fixes, exec lease release on both the success and failure paths, and the regression case that previously emitted source cannot be empty.

Exercised end-to-end against a live daemon with a real encrypted store:

  • reproduced the original error byte-for-byte against a pre-fix build;
  • secrets env writes .env at 0600 with the earliest lease expiry;
  • per-entry TTLs (10m/2h) are honoured and the file expires at the earliest;
  • secrets exec injects the variables and revokes its leases on exit.

The exec leak was confirmed against a pre-fix build (active leases 4 → 5) and confirmed fixed afterwards (exit code 3 preserved, leases unchanged).

Notes for review

  • CI on main is currently red, for reasons unrelated to this PR: golangci-lint reports pre-existing errcheck findings in internal/daemon, internal/audit, internal/scanner, internal/cleanup, internal/types, internal/adapters/vercel, internal/config, internal/lease, internal/otel, and internal/update; and goreleaser check fails on deprecated archives.format / archives.format_overrides.format in .goreleaser.yml. This PR touches none of those files and adds no new lint findings. Happy to split either fix into a separate PR.
  • internal/daemon tests fail on hosts where t.TempDir() is group-writable (a local umask of 002); they reject group/other-writable socket directories by design. This is environmental and reproduces on the base commit. Under CI's umask 0022 the whole suite passes.
  • AGENTS.md is byte-identical to CLAUDE.md, and .claude/skills / .opencode/skills are symlinks to skills/, so those needed no edits.

Follow-ups (not addressed here)

  • The doppler source is still an unimplemented stub.
  • secrets cleanup --dry-run is not implemented; the docs now describe the real flags.

Summary by CodeRabbit

  • New Features
    • secrets env supports store-backed and provider-backed configurations, with dry-run previews and configurable secret lifetimes. Store-backed output defaults to .env; provider-backed output defaults to .env.local.
    • secrets exec supports both configuration types, passes secrets to the command without writing them to disk, and revokes store-backed leases when the command exits.
  • Documentation
    • Added guidance on configuration formats, secret lifetimes, cleanup watch intervals, and secrets exec behavior.

Intent:
- Make `secrets env` and `secrets exec` work with the store-backed
  .secrets.json shape that README.md, AGENTS.md, CLAUDE.md, and the bundled
  skills already document.
- Replace the misleading "source cannot be empty" failure, which blamed the
  user for a schema the code never accepted.

Implementation:
- Add SecretMapping, ProjectConfig.Secrets, and ProjectConfig.ClientID.
- Split validation into store-backed and provider-backed paths, dispatched by
  IsStoreBacked(), so `source` is only required for provider-backed configs.
- Reject duplicate env_var entries and validate per-entry TTLs.
- Default the output file per mode: .env for store-backed, .env.local for
  provider-backed.
- Lease each secret over RPC in `secrets env` (writes .env at 0600, TTL equal to
  the earliest lease expiry) and in `secrets exec` (injects into the subprocess
  and revokes the leases on exit).
- Share one TTL resolver between the dry-run preview and the real lease path so
  `--dry-run` reports the TTL each secret will actually be leased with.
- Route lease failures to an actionable fix: a missing secret suggests
  `secrets list` rather than misreporting a stopped daemon.
- Return the child's exit code from `secrets exec` instead of calling os.Exit,
  which skipped deferred cleanup and leaked the run's leases whenever the
  wrapped command failed.
- Keep secret values out of the JSON envelope; report lease metadata only.
- Refresh the `env` command-tree help text, which is part of the stable agent
  contract, and its `--dry-run` flag description.
- Extract shared lease helpers into cmd/secrets/project_leases.go.

Outcomes:
- A .secrets.json containing a `secrets` array with `env_var` entries no longer
  fails project config validation.
- A failing `secrets exec` no longer leaves credential leases active.
- Provider-backed configs behave exactly as before.

Verification:
- go build ./... and go vet ./... pass; changed files pass gofmt -s.
- go test -race ./... passes under a umask of 0022, matching CI.
- New coverage for store-backed loading, validation errors, TTL precedence
  (entry vs config vs flag), lease-failure fixes, exec lease release on both the
  success and failure paths, and the regression case that previously emitted
  "source cannot be empty".
- Exercised end-to-end against a live daemon with a real store: `secrets env`
  wrote .env at 0600 with the earliest lease expiry, `secrets exec` injected the
  variables and revoked its leases on exit, and per-entry TTLs (10m/2h) were
  honored while the file expired at the earliest. The exec leak was confirmed
  against a pre-fix build (active leases 4 -> 5) and confirmed fixed after.

Follow-ups:
- The doppler source is still an unimplemented stub.
- `secrets cleanup --dry-run` is documented in the README but not implemented;
  the docs now describe the real --path/--watch flags instead.

📝 Walkthrough

Walkthrough

The project configuration and CLI commands now support store-backed secrets alongside provider-backed configurations. secrets env writes leased values to an env file. secrets exec injects resolved values into a subprocess and revokes store-backed leases when it exits.

Changes

Secrets configuration and commands

Layer / File(s) Summary
Configuration shapes and validation
internal/project/config.go, internal/project/config_store_test.go, README.md
ProjectConfig supports store-backed secret mappings, TTLs, and client IDs. Validation and env-file defaults vary by configuration mode. Tests and documentation describe both schemas.
Env-file generation and leases
cmd/secrets/env.go, cmd/secrets/project_leases.go, cmd/secrets/env_test.go, cmd/secrets/root.go, README.md
secrets env dispatches by configuration mode. Store-backed execution validates TTLs, acquires leases, and writes leased values with TTL metadata and mode 0600. Tests cover dry-run TTL precedence and lease failures. Documentation describes env generation and cleanup options.
Secret injection and lease cleanup
cmd/secrets/exec.go, cmd/secrets/exec_test.go, README.md
secrets exec resolves secrets from either configuration mode and injects them into the subprocess environment. It revokes store-backed leases after success or failure. Tests cover lease cleanup and child exit codes.

Merge Risk: 🟡 Moderate · up to 2bdad

Store-backed commands can leave leases active after failure, briefly or persistently expose an env file to other local users, or write malformed variable mappings. Resolve these issues before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 2bdad

Store-backed secrets can now be written to project files or passed to commands. The review found a window in which a new secrets file may be readable before its permissions are restricted, and a failure path that can leave acquired leases active. The observed exposure is local and bounded, but these are meaningful changes to how secrets are handled.

Retained concerns

  • Medium · security · observed: New store-backed output writes plaintext through os.Create before restricting the file to 0600. A newly created file may initially inherit permissive umask-derived permissions; an existing file retains its permissions during truncation and writing.
  • Low · security · observed: If a later secret cannot be leased or its response cannot be decoded, acquisition drops the IDs of earlier successful leases. Neither caller can revoke that partial set; it remains active until expiry.
  • Low · reliability · inferred: Independent project runs using the same client ID and secret name can replace one another’s active daemon lease. The new project-driven callers make that shared identity an ownership and audit-lifecycle concern, not an authorization bypass established by this review.
Security review details

Security Blast Radius

  • inferred — A project configuration can select names from secrets reachable through the invoking user’s daemon connection and expose returned values in that project’s env file or a subprocess. The reviewed handler establishes no project namespace; socket-level caller access was not established here.

Security Findings and Attack Paths

  • observed — The two retained file-exposure findings share one condition: plaintext writing precedes chmod. Existing-file checks and a restrictive umask can narrow exposure, but neither makes restrictive permissions a precondition for writing on this path.
  • observed — The retained partial-acquisition finding follows a later RPC or decoding error: successful earlier lease IDs are discarded before either caller receives them. The demonstrated outcome is lost cleanup ownership, not additional authority to read a secret.

Trust Boundaries and Controls

  • observed — The daemon retrieves a named store secret before acquiring its lease. Client ID identifies a lease but is not an authorization check in the inspected handler; the lease manager replaces an active lease with the same secret name and client ID.

Resilience and Maintainability Implications

  • observed — Successful exec acquisition retains lease IDs for deferred revocation, including after child failure. That protection does not cover errors inside acquisition or a process terminated without running defers.

Hardening Proposals

  • proposed — Establish restrictive file permissions before writing any returned secret value, and preserve the intended permissions during replacement.
  • proposed — Give partial acquisition an explicit rollback owner, and define whether project lease identities must be unique or may intentionally replace leases held by other runs.

Revoke leases when env-file setup fails.

After acquireProjectLeases succeeds, the expired-lease, WriteWithTTL, and Chmod error paths return without calling revokeLeases. The daemon keeps those leases active until their TTL expires, although the command did not complete the secured env-file handoff. Add failure-only cleanup after acquisition and keep the leases on the successful path.

Sensitive Data Exposure

Reachability: Internal

CWE: CWE-732 — Incorrect Permission Assignment for Critical Resource

Set mode 0600 before writing secret values.

envfile.WriteWithTTL uses os.Create, which requests mode 0666. With umask 0022, a new file is readable by other local users while plaintext values are written. The caller applies 0600 only after the write succeeds. In --force mode, an existing file keeps its prior mode until Chmod. If writing or Chmod fails, readable partial or complete contents can remain.

Set the mode before writing:

Set restrictive permissions in WriteWithTTL
-	f, err := os.Create(path)
+	f, err := os.OpenFile(path, os.O_WRONLY|os.O_CREATE|os.O_TRUNC, 0600)

Revoke the leases already acquired when a later lease fails.

acquireProjectLeases returns nil, err if a later entry fails. This happens when the secret is not found, the RPC fails, or the response cannot be decoded. The function then discards the leases it already acquired. After that, no caller can revoke them.

  • In resolveExecSecrets (cmd/secrets/exec.go Line 199-202), the cleanup function is set only after acquireProjectLeases succeeds. The PR states that secrets exec revokes leases on exit. That promise fails here: the acquired credential leases stay active until their TTL expires.
  • secrets env leaks the same leases.
Proposed fix
 		resp, err := rpcCall(socketPath, daemon.MethodLease, params)
 		if err != nil {
+			revokeLeases(leases)
 			return nil, fmt.Errorf("failed to lease %q: %w", entry.Name, err)
 		}
 
 		var result daemon.LeaseResult
 		data, err := json.Marshal(resp.Result)
 		if err != nil {
+			revokeLeases(leases)
 			return nil, fmt.Errorf("failed to parse lease for %q: %w", entry.Name, err)
 		}
 		if err := json.Unmarshal(data, &result); err != nil {
+			revokeLeases(leases)
 			return nil, fmt.Errorf("failed to parse lease for %q: %w", entry.Name, err)

Reject env-file delimiters in SecretMapping.EnvVar.

validateStoreBacked accepts newline and = characters. The reachable secrets env path passes the configured names to envfile.WriteWithTTL, which writes each entry as raw key=value\n. For example, EnvVar: "APP_KEY\nOTHER_KEY" creates a second assignment line. envfile.Read then parses OTHER_KEY as a separate variable and loses the configured mapping.

Reject at least \r, \n, and = during store-backed validation.
