Summary

Adds engram (Gentleman-Programming/engram) to the registry, with aqua: as the primary backend and github: as a fallback, so mise use -g engram@latest works.

Popularity

  • GitHub: 6,185 stars, 655 forks, last release v1.20.0 (2026-07-20)
  • Persistent memory system for AI coding agents (Claude Code, OpenCode, Codex, Gemini CLI)

Known transient issue: aqua-registry vendor lag

The aqua:Gentleman-Programming/engram entry in aquaproj/aqua-registry merged today (2026-08-27): aquaproj/aqua-registry#59476 (merge commit 4b4fc52).

mise's own vendored aqua-registry snapshot (vendor/aqua-registry/) is currently pinned to aqua-registry commit 6d546dfab62d3ff4ee47312222c9559b82f6b3f4, re-vendored as part of yesterday's mise release (2026.8.14), which happened before the engram aqua PR merged. Verified via the GitHub compare API:

$ gh api repos/aquaproj/aqua-registry/compare/6d546dfab62d3ff4ee47312222c9559b82f6b3f4...4b4fc5275614833bb58bbbb05fd555ff6a889e7b --jq '{status, ahead_by, behind_by}'
{"status":"ahead","ahead_by":62,"behind_by":0}

So right now, mise ls-remote engram (which resolves via the aqua: backend first) returns no versions locally, purely because of this vendoring lag — not because of anything wrong with the registry entry itself. Based on this repo's release cadence (roughly daily per recent release history), this should self-resolve at mise's next release, which re-vendors aqua-registry as a standard part of the release process.

The github: backend (secondary, live, not vendored) resolves correctly today:

$ ./target/debug/mise ls-remote github:Gentleman-Programming/engram
...
1.18.0
1.19.0
1.20.0
$ ./target/debug/mise latest github:Gentleman-Programming/engram
1.20.0

(The repo also publishes an unrelated companion npm package under pi-vX.Y.Z tags, which show up in the raw tag list above but are correctly ignored by version_order = "semver" when resolving latest.)

I'm opening this now with that caveat stated plainly rather than waiting, consistent with how registry/gentle-ai.toml (#12444) was handled. Only the aqua: backend is affected transiently; the entry itself is correct.

Test evidence

Built from source (default features; --all-features currently fails locally on an unrelated aws-lc-sys/bindgen path unrelated to this change) and ran the real binary against this branch:

$ ./target/debug/mise test-tool --raw engram
mise cleaning engram       ✓ done
mise WARN  Latest version cannot be fetched: registry not available: no aqua-registry found for Gentleman-Programming/engram
mise WARN  Remote versions cannot be fetched for Gentleman-Programming/engram: registry not available: no aqua-registry found for Gentleman-Programming/engram
mise WARN  Failed to resolve tool version list for engram: [--runtime] engram@latest: unable to fetch versions for engram: registry not available: no aqua-registry found for Gentleman-Programming/engram
mise WARN  no versions found for engram
mise engram: OK

Because of the vendor lag above, this specific local run resolves zero versions via the primary aqua: backend and short-circuits (mise test-tool treats "no resolvable version" as a no-op pass rather than a failure — see src/cli/test_tool.rs around the no versions found for {tool} warning). So while it does print OK, that's not a substitute for a real install+run cycle.

As the closest available real evidence of the test field's correctness, I resolved and ran the actual engram binary via the working github: backend directly:

$ engram version
engram 1.20.0

This matches test = { cmd = "engram version", expected = "engram {{version}}" } (no v prefix, consistent with sibling entries like registry/oha.toml and registry/ty.toml).

taplo format registry/engram.toml produces no diff (already conforms to .taplo.toml's schema-driven key ordering).

Other notes

  • No os restriction: engram publishes Linux, macOS, and Windows release archives, so all platforms are supported.
  • Commit is signed (SSH).

Checklist

  • Registry entry includes a test field
  • Popularity evidence included above
  • mise test-tool run against a local build (see caveat above re: aqua vendor lag)
  • taplo format produces no diff

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds registry metadata for the Engram package. It defines Aqua and GitHub backends, the engram binary, package description, version validation command, and semantic version ordering.

Changes

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to b6931

The new entry currently cannot resolve Engram through the default workflow because the preferred registry snapshot does not yet include it; users can still use the GitHub backend explicitly, and the default path should recover with the next registry refresh. This is a bounded follow-up risk rather than a broader merge blocker.

A rabbit checks the registry door
Engram’s name is written on the floor
Aqua and GitHub point the way

🌐 Web query:

aquaproj aqua-registry Gentleman-Programming engram registry.yaml

💡 Result:

The terms mentioned belong to two distinct projects: aquaproj/aqua and Gentleman-Programming/engram. aquaproj/aqua-registry is the standard registry for the aqua tool manager [1][2]. In the context of aqua, a registry.yaml file is a configuration file used to define package metadata, such as installation methods (e.g., github_release, go_build), platform support, and checksum verification [3][2]. Gentleman-Programming/engram is a separate project providing a persistent memory system for AI coding agents [4][5]. While engram uses a registry-based approach internally to manage setup configurations for various AI agents (like Claude Code, Cursor, and Windsurf), it is not a package managed by the aquaproj/aqua-registry [4][6]. The engram project uses its own internal registry logic (located at internal/setup/registry.go) to handle agent-specific MCP (Model Context Protocol) configurations [6]. There is no functional integration between aquaproj/aqua-registry and Gentleman-Programming/engram; they simply share common terminology regarding registries (a common pattern in CLI tools for configuration management) [6][2].

Use a resolvable preferred backend.

aqua.baked_registry defaults to true, and the baked Aqua registry does not contain Engram. AquaBackend::_list_remote_versions returns an empty list when the package lookup fails. RegistryTool::ba() selects the first backend, so the GitHub entry is not used for this default resolution.

Add Engram to the Aqua registry first, or remove the Aqua backend and use GitHub alone. Run mise ls-remote for the selected backend and confirm that it returns installable versions.

The vendored aqua-registry snapshot was updated in v2026.8.15 (commit ee2a510b), and it now includes this package's entry (pkgs/Gentleman-Programming/*).

The registry-ci / test-tool-0 failures above are from the previous run (2026-08-27), before that update, so they're stale. Could someone re-run the checks on this PR when convenient?
