what

  • Adds from-mise.md and from-aqua.md to the atmos-migration agent skill, guiding an agent or user through migrating tool-version management from mise or Aqua CLI to the Atmos toolchain.
  • Flips toolchain.use_lock_file's default from false to true via the editions system, so atmos toolchain install writes toolchain.lock.yaml (pinned resolved versions and checksums) automatically instead of requiring an undocumented opt-in setting. Projects pinned to an edition dated before this change keep the previous opt-in default.
  • Fixes atmos toolchain set: it now actually changes a tool's default version (previously it only appended, like add), and updates an existing .tool-versions entry in place instead of duplicating it under the resolved owner/repo form when the file uses a short alias.
  • Fixes a markdown-rendering bug where any ui.* formatted message containing word@version-shaped text (e.g. jq@1.9.0) silently lost that text in terminal output.
  • Adds a changelog post and roadmap entry for the use_lock_file default change, per this repo's minor-label release-doc requirements.

why

  • Hands-on field testing of the new from-mise.md/from-aqua.md migration recipes — building real mise/aqua fixtures and following each recipe verbatim — surfaced all of the bugs fixed here, rather than just reading the code and assuming it worked.
  • The wrong kubectl registry alias (kubernetes-sigs/kubectl instead of kubernetes/kubectl) broke atmos toolchain install for both docs' flagship first example.
  • toolchain.lock.yaml never got written in any of the field-test fixtures despite the doc's claim that it's automatic — tracing this down found the setting was opt-in, undocumented, and therefore essentially unused, so tool installs weren't actually reproducible across machines/CI by default.
  • The doc's CLI mapping pointed mise use (which changes the active tool version) at atmos toolchain add (which only appends), and testing the more semantically correct atmos toolchain set found it was broken in two separate ways — a real product bug, not just a docs inaccuracy.

references

  • Field-tested against real mise/aqua fixtures built under .context/field-test-mise-aqua/ (not committed).

Summary by CodeRabbit

  • New Features

    • Toolchain installs now create and use toolchain.lock.yaml by default, recording versions, download URLs, checksums, and platform-specific sizes for reproducible installations.
    • Added migration guidance for moving from Terramate, mise, and Aqua CLI to Atmos.
  • Bug Fixes

    • Tool version updates now preserve user-specified names and correctly handle aliases without creating duplicate entries.
    • Improved resilience against transient Windows test failures, dependency-download interruptions, and delayed Floci service startup.
    • Increased the Windows Terraform registry cache test timeout to reduce failures on degraded runners.

…l alias

Add from-mise.md and from-aqua.md scenario-keyed migration guides to the
atmos-migration skill, wired in via SKILL.md and AGENTS.md.

Field-testing these docs against real fixtures found two bugs, fixed here:
kubectl's Aqua registry owner/repo is kubernetes/kubectl, not
kubernetes-sigs/kubectl (the wrong alias broke `atmos toolchain install`
for both docs' flagship Shape A example), and the `mise use` CLI mapping
pointed at `atmos toolchain add` (append-only) instead of `atmos toolchain
set` (which actually changes the default version).

…ditorConfig

from-mise.md and from-aqua.md used 3-space continuation under numbered
list items, matching this skill's other reference docs but failing this
repo's EditorConfig rule (multiple of 2). Shift continuation blocks
(including nested YAML/text fences) to 4-space uniformly; no content
changed.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
toolchain.lock.yaml pins resolved tool versions and checksums for
reproducible installs, but writing it was opt-in and undocumented
(use_lock_file defaulted to false). Field-testing the mise/aqua migration
docs found their "the lockfile writes automatically" claim didn't hold in
practice for exactly this reason.

Flip the default via the editions system (pkg/edition/journal.go) rather
than a bare default change, so projects pinned to an edition before this
change keep the old opt-in behavior.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…t loss

atmos toolchain set claimed to set a tool's default version but called
the same append-only helper as add, so it never reordered .tool-versions,
and used the resolved owner/repo form to write the file instead of the
name the caller passed, silently duplicating entries for aliased tools
(e.g. "jq") instead of updating them in place. Fixed by calling
AddToolToVersionsAsDefault with the original tool name, matching add.go's
already-correct, already-tested pattern.

Separately, set's own success message silently dropped the tool@version
text it reported (e.g. "Set  in .tool-versions"). Root cause: goldmark's
GFM autolink pass mistakes word@version text for an email address; the
strict-linkify extension correctly un-links it but replaced it with an
ast.KindString node glamour's ANSI renderer has no render case for, so
the text vanished. Any ui.* formatted message with this shape hit the
same bug. Fixed by rebuilding a source-backed ast.Text node instead.

Both were found while field-testing the mise/aqua migration skill docs,
which document `set` as the command a mise-style "make this version
active" migration needs.

…havior

CI acceptance tests (linux, macos) failed: TestToolchainSetTool_Execute
asserted the old behavior where SetToolVersion wrote .tool-versions under
the resolved canonical owner/repo form. That behavior was intentionally
changed in the prior commit (matching AddToolVersion's already-correct
pattern) but this MCP/AI-tool wrapper's test, in a different package,
wasn't updated at the same time.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
CI acceptance tests (linux, macos, windows) failed: TestCLICommands'
describe-config-family snapshots didn't account for the
toolchain.use_lock_file default flip landing earlier in this branch --
atmos describe config now resolves and renders that field (and the
previously all-zero-value toolchain block, no longer empty) differently
than what the committed .golden files expected.

Regenerated via `go test ./tests -run 'TestCLICommands/...' -regenerate-snapshots`
per this repo's golden-snapshot policy; diff is exactly the expected
use_lock_file: false -> true change, no unrelated output shifted.

…fix mise mappings

Addresses CodeRabbit review on PR #2899:
- from-aqua.md: carry the aqua.yaml ref: pin into the converted
  toolchain.registries[] entries (public and custom registry examples) instead
  of dropping it -- an unpinned registry, like an unpinned branch ref, can
  change what gets installed without any change to atmos.yaml.
- from-aqua.md: document that automatic toolchain.lock.yaml management depends
  on the project's edition; projects pinned before 2026-08-05 need
  toolchain.use_lock_file: true explicitly.
- from-mise.md: mise prune has no direct Atmos equivalent (it prunes unused
  versions only); atmos toolchain clean remains the mise implode mapping.
- SKILL.md: add .mise/config.toml to the mise routing entry so repos using
  that path still route to from-mise.md.

…onical key

AddToolToVersionsAsDefault (via addToolToVersionsInternal) returned early
whenever findDuplicateKey (formerly wouldCreateDuplicate) matched, even when
the caller wanted the version promoted to the default position. When a
version was already tracked under a *different* key than the caller passed
-- the alias vs. its canonical owner/repo form, or vice versa -- promoting it
silently did nothing instead of reordering it within its existing key.

Same-key updates (e.g. "jq 1.9.0 1.7.1" -> promote 1.7.1) were unaffected:
findDuplicateKey never matches within the same key, so AddVersionToTool's
existing reorder loop already handled that case correctly. Added a
regression test for both the same-key case (documenting the pre-existing
correct behavior) and the cross-key case (reproducing and fixing the bug).

findDuplicateKey/aliasConflictsWithFullName/fullNameConflictsWithAlias now
return the conflicting key instead of a bool, so the caller can promote
within it.

TestCustomRenderer_Render_PackageRefLinkify only exercised two *different*
package-ref labels in one message, so an implementation that dedupes by label
and keeps only the first occurrence would still pass. Add a case with the
same reference repeated and assert the rendered occurrence count, not just
presence.

Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The toolchain lockfile pins the resolved artifact per platform, so two
different operating-system/architecture combinations can legitimately resolve
to different artifacts for the same declared version. Reword the "byte-for-
byte the same artifact" claim in the blog post and roadmap entry to be scoped
to installs on the same OS/architecture, matching what the lockfile actually
guarantees.

270-296: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Avoid non-deterministic alias promotion.

toolVersions.Tools is a Go map. This function returns the first matching alias. If two aliases resolve to tool and contain version, map iteration selects one alias without a stable order. AddToolToVersionsAsDefault then promotes only that arbitrary entry.

Collect all matching keys. Then promote all equivalent entries or return a static ambiguity error. Add a regression test with two aliases that resolve to the same canonical tool.

As per coding guidelines, “Wrap all errors with static errors from errors/errors.go” if this state returns an error.

315-361: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Use a table for the new promotion scenarios.

These cases repeat the same setup, promotion, load, and assertion flow. Put the tool key, stored key, versions, and expected result in test cases. Add the canonical-to-alias scenario to the same table.

As per coding guidelines, “Use table-driven tests for testing multiple scenarios in Go.”

Not fixed: image-size (alerts #276, #275, high) -- GitHub reports no
patched version exists yet for either advisory (first_patched_version
is null on both). Nothing to bump to; revisit once upstream ships a fix.

TestAzureSecretsFlociE2E failed with "Floci HTTP endpoint is not
reachable at http://localhost:4577" -- the TCP dial succeeded but the
HTTP GET timed out, a startup race where the socket accepts
connections before the app inside is ready to respond. CI's service
containers have no health-check configured, so requireFlociEndpoint's
single 2s check was the only readiness gate, far stricter than the 90s
flociStartupTimeout the local testcontainers auto-start path already
grants for this exact scenario.

requireFlociEndpoint now polls via a new pollUntil helper for up to
flociStartupTimeout instead of checking once. Added unit tests for
pollUntil directly.

Preserve id-token: write across the reusable-workflow boundary.

Its GoReleaser configuration uses keyless cosign signing, so the release can fail when it cannot mint an OIDC token. Update the called workflow or use a revision that grants this permission.

Use a table-driven test for the polling scenarios.

These tests cover multiple scenarios for one helper. Consolidate them into table-driven cases with per-case callbacks, expected errors, and expected call counts.

Check the deadline before invoking fn (not just after) and cap the
retry sleep to the remaining time, so a slow fn call near the deadline
can no longer push the total run time well past the intended timeout.

atmos toolchain install skips tools already on disk, so it won't add a
lock entry for them. Point readers to atmos toolchain lock (or
--reinstall) to backfill, and scope the byte-for-byte reproducibility
claim to platforms with a matching lock entry.
