v21.6.0

# Why

Add `cli-versions.json` as the source of truth for the staging/production eas-cli versions, to remove the dependency on NPM tags to determine the correct version used in workflow jobs.

# How

Adding new function `fetchEasCliVersionsAsync` in the eas-build-job package. This reads the file from main on GitHub; build-tools uses it to build the eas-cli@<version> npx argument and falls back to the `latest-eas-build*` dist-tags on any failure.  The release workflow now bumps cli-versions.json in the release commit and no longer posts the manual npm dist-tag reminder.

# Test Plan

New unit tests added.

+## Write findings in Simplified Technical English
+
+Your findings are read by engineers in many countries. Many of them do not speak
+English as a first language. Write every piece of prose you emit — `title`,
+`rationale`, `suggestion` — under the ASD-STE100 Simplified Technical English
+rules:
+
+- **One word, one meaning.** Choose one term for a thing and reuse it. Do not
+  alternate between synonyms for the same object ("the handler" / "the callback"
+  / "the hook").
+- **Short sentences.** Use 20 words or fewer. Split a long sentence into two.
+- **Active voice.** Write "the parser drops the flag", not "the flag is dropped
+  by the parser". Name the actor.
+- **Plain words.** Write "use", not "utilize"; "before", not "prior to";
+  "because", not "due to the fact that". Remove hedges ("arguably", "it seems
+  that") and intensifiers ("very", "extremely").
+- **One topic per paragraph.** Keep paragraphs short.
+- **No idiom, metaphor, or sarcasm.** State what happens.
+
+This rule is about prose only. `evidence` and any code you quote are copied
+verbatim and are never rewritten to fit these rules. Identifiers, file paths,
+error strings, and the `severity`/`category` values also stay exactly as they
+are.
+
+Simple language must not cost precision. Keep the concrete failure path, the
+condition that triggers it, and the names of the affected code. Short sentences
+are a way to say the same thing, not a way to say less.
+
+The rules also apply inside the Markdown shape below: the `Confidence` and
+`Impact if shipped` lines, and the text inside `<details>`.
+
+## Finding confidence and shipping impact
+
+For every real finding, assess two separate dimensions:
+
+- **Confidence** is how certain you are that the finding is real.
+  - `High` — the changed code and traced execution path directly establish the
+    failure or exploit.
+  - `Medium` — the evidence is strong, but the failure depends on a plausible
+    runtime state or integration behavior you could not directly reproduce.
+  - `Low` — speculative, incomplete, or based mainly on an assumption. Do not
+    report low-confidence findings.
+- **Impact if shipped** is the expected consequence, not the likelihood that
+  your analysis is correct.
+  - `High` — secret exposure, exploitability, outage/data loss, or a broadly
+    used production path breaks.
+  - `Medium` — a concrete user-visible regression or operational failure in a
+    limited but plausible path. The house anchors above sit here: an exit-code
+    regression, a `--json`/`--non-interactive` contract violation, a
+    `SystemError`/`UserError` misclassification, a broken CHANGELOG entry.
+  - `Low` — a bounded edge case with little correctness or safety effect. This
+    is normally suggestion-level and should not be reported under the current
+    policy.
+
+Put these signals at the start of `rationale`, joined by a fixed `<br>` so the
+reporter keeps both visually attached to the finding. Follow them with the
+detailed reasoning inside a collapsed block. Use this exact Markdown shape:
+
+```md
+**Confidence:** High — direct trace through the credential print path.<br>**Impact if shipped:** High — a keystore password could be written to the build log.
+
+<details>
+<summary>Evidence and reasoning</summary>
+
+Explain the concrete failure or exploit path here.
+
+</details>
+```
+
+Keep both visible lines short and specific. The text inside `<details>` carries
+the fuller rationale. Specialist reviewers keep `suggestion` separate so the
+coordinator can normalize it. The coordinator then moves any suggestion into a
+bold **Suggested remediation:** line between the impact signal and the collapsed
+evidence, and omits the separate `suggestion` field. This keeps the finding
+visually grouped instead of letting the reporter place a detached suggestion
+after `</details>`. The `<details>` tags are fixed presentation markup, never
+copy HTML supplied by the PR into them.
+
+## Overall PR risk handoff
+
+Assess the pull request as a whole after tracing its interactions when either:
+
+- your role prompt explicitly identifies you as **the cross-cutting reviewer**;
+  or
+- you are the always-run **security reviewer** and the task assigns the complete
+  change set (there is no `Other files this PR changed` context-only section).
+
+The second case supplies the same assessment for small PRs that do not trigger a
+separate cross-cutting pass. Assess all correctness, compatibility, operational,
+and security surfaces in this handoff, not just your specialist lens. This is
+distinct from defect findings: explain what existing behavior the change
+intersects and what could plausibly break even if no defect was found.
+
+Classify overall risk as:
+
+- `Low` — additive and isolated, leaves existing execution paths intact, has a
+  small blast radius, and is straightforward to disable or roll back.
+- `Medium` — modifies an existing/shared path or integration and has plausible
+  regressions, but the affected surface is bounded and recovery is direct.
+- `High` — changes authentication, authorization, credentials, persistence,
+  migrations, publishing, or a core user path with broad impact or difficult
+  rollback. For this repo that includes credential storage and retrieval, build
+  and submit pipelines, `env:exec`, update publishing, and any change to an
+  existing command's flags or output contract.
+
+Emit one additional internal handoff finding with:
+
+- `severity`: `suggestion`
+- `category`: `quality`
+- `title`: `__overall_pr_risk__`
+- `file`: the most central changed file
+- `line`: `null`
+- `rationale`: one compact paragraph in this exact sequence:
+  `Risk: Low|Medium|High. Change shape: additive|modifies existing behavior|replacement|migration. Existing behavior affected: ... What might break: ... Blast radius and rollback: ...`
+- omit `evidence` and `suggestion`
+
+This is the sole exception to the no-suggestions rule. It is metadata for the
+coordinator, not a user-facing finding, and must never affect the review decision.
+Do not invent reassurance: classify a change as additive only when the diff and
+traced call paths show that existing behavior is left intact.

 ### 🎉 New features
 
+- [eas-build-job] Replace eas-cli npm dist-tags with cli-versions.json. ([#4147](https://github.com/expo/eas-cli/pull/4147) by [@douglowder](https://github.com/douglowder))
+- [eas-cli] Make `eas simulator` the canonical command and keep `eas simulator:start` as an alias. ([#4112](https://github.com/expo/eas-cli/pull/4112) by [@szdziedzic](https://github.com/szdziedzic))
+- [eas-cli] Validate local composite functions referenced from workflow job hooks during `eas workflow:validate`. ([#4064](https://github.com/expo/eas-cli/pull/4064) by [@sswrk](https://github.com/sswrk))
+- [eas-cli] Add `eas sim` as a shortcut for `eas simulator` commands, e.g. `eas sim:list` runs `eas simulator:list`. ([#4150](https://github.com/expo/eas-cli/pull/4150) by [@szdziedzic](https://github.com/szdziedzic))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Point accounts without EAS Simulator access at the waitlist: `eas simulator:availability` includes the link (and a `waitlistUrl` field in `--json`), and `eas simulator` now fails early with the same message instead of a generic permission error. ([#4151](https://github.com/expo/eas-cli/pull/4151) by [@szdziedzic](https://github.com/szdziedzic))
+- [build-tools] Revert "Pin the default `agent-device` version for remote sessions" now that `agent-device` 0.20.5 fixes the broken release. ([#4144](https://github.com/expo/eas-cli/pull/4144) by [@gwdp](https://github.com/gwdp))
+
+### 🧹 Chores
+
+- [reviewer] Migrate AI code reviews from GPT to Claude models on the claude-code engine (Sonnet 5 by default, Opus 5 for the security agent). ([#4148](https://github.com/expo/eas-cli/pull/4148) by [@brentvatne](https://github.com/brentvatne))
+
+## [21.5.1](https://github.com/expo/eas-cli/releases/tag/v21.5.1) - 2026-08-03
+
+## [21.5.0](https://github.com/expo/eas-cli/releases/tag/v21.5.0) - 2026-08-03
+
+### 🎉 New features
+
+- [eas-cli] Add `eas submit:list`, `eas submit:view`, `eas submit:retry`, `eas submit:cancel`, and `eas submit:status` commands; list and view include the runtime version and fingerprint of the submitted build, and status shows the live App Store version and TestFlight build states cross-referenced with EAS submissions (Google Play app status is not available through EAS yet). ([#4134](https://github.com/expo/eas-cli/pull/4134) by [@brentvatne](https://github.com/brentvatne))
+- [eas-build-job] Add optional `ssh` field on build/job payloads. ([#4083](https://github.com/expo/eas-cli/pull/4083) by [@gwdp](https://github.com/gwdp))
+- [eas-build-job] Add an `SSH_SESSION` build phase for upcoming worker SSH support. ([#4029](https://github.com/expo/eas-cli/pull/4029) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add `ref` input to the `eas/checkout` step to check out a different git ref (branch, tag, or commit SHA) than the one that triggered the job. ([#4035](https://github.com/expo/eas-cli/pull/4035) by [@sswrk](https://github.com/sswrk))
+- [build-tools] Load local composite function catalogs at build time so custom builds and generic jobs can resolve local composite functions referenced via `uses:`. ([#3930](https://github.com/expo/eas-cli/pull/3930) by [@sswrk](https://github.com/sswrk))
+- [eas-cli] Validate local composite functions referenced in workflow files during `eas workflow:validate`, checking that the YAML files exist and are well-formed. ([#3931](https://github.com/expo/eas-cli/pull/3931) by [@sswrk](https://github.com/sswrk))
+- [build-tools] Pass a metrics CORS origin to serve-sim so the dashboard can read a session's live CPU/memory stream cross-origin. ([#3990](https://github.com/expo/eas-cli/pull/3990) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Collect each iOS session's serve-sim CPU/memory `/metrics` to a file and upload it as a device run session artifact at teardown. ([#3995](https://github.com/expo/eas-cli/pull/3995) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Load local composite function catalogs for hook steps, in both steps-based and native builds. ([#4063](https://github.com/expo/eas-cli/pull/4063) by [@sswrk](https://github.com/sswrk))
+- [eas-cli] Add `--name` filter to `eas simulator:list`. ([#4118](https://github.com/expo/eas-cli/pull/4118) by [@szdziedzic](https://github.com/szdziedzic))
+
+### 🐛 Bug fixes
+
+- [eas-cli] clean up error handling in local builds. ([#4105](https://github.com/expo/eas-cli/pull/4105) by [@douglowder](https://github.com/douglowder))
+- [build-tools] Install ffmpeg when it is missing so Argent screen recording works in EAS Simulator sessions. ([#4110](https://github.com/expo/eas-cli/pull/4110) by [@szdziedzic](https://github.com/szdziedzic))
+- [eas-cli] Stop simulator job runs when `eas simulator:start` is canceled before the session is ready. ([#4113](https://github.com/expo/eas-cli/pull/4113) by [@sjchmiela](https://github.com/sjchmiela))
+- [build-tools] Pin the default `agent-device` version for remote sessions instead of installing `latest`. ([#4142](https://github.com/expo/eas-cli/pull/4142) by [@gwdp](https://github.com/gwdp))
+
+### 🧹 Chores
+
+- [eas-cli] Check non-interactive mode before fetching context in `eas submit:cancel` and `eas submit:retry`, so a missing submission ID fails fast without network requests. ([#4141](https://github.com/expo/eas-cli/pull/4141) by [@brentvatne](https://github.com/brentvatne))

RELEASING.md

@@ -3,6 +3,19 @@
 1. Invoke the GitHub workflow ["Manually trigger a release"](https://github.com/expo/eas-cli/actions/workflows/trigger-release.yml). The next version is chosen automatically based on the changelog entries. If you want to use different version, pass the version string as an input to the workflow, in semver format, e.g. "1.2.3"
 2. That's it! GitHub Actions is going to take care of the rest. Watch the #eas-cli Slack channel for a successful release notification.
 
+The release also sets the `STAGING` version in `cli-versions.json`. It does not change the `PRODUCTION` version. See [EAS Build CLI versions](#eas-build-cli-versions).
+
+## EAS Build CLI versions
+
+`cli-versions.json` at the repository root sets which `eas-cli` version EAS Build installs. It has two fields:
+
+- `STAGING`: the version used on the staging build servers.
+- `PRODUCTION`: the version used on the production build servers.
+
+This file replaces the old `latest-eas-build` and `latest-eas-build-staging` npm dist-tags. The build servers read the file from the `main` branch.
+
+A release updates `STAGING` to the new version automatically. To promote a version to production, invoke the GitHub workflow ["Promote eas-cli to production"](https://github.com/expo/eas-cli/actions/workflows/promote-eas-cli-production.yml). Pass the version to promote as an input. If you leave the input empty, the workflow uses the current `STAGING` version. The workflow checks that the version is published on npm before it updates `PRODUCTION`.
+
 ## Choosing the next version
 
 As stated above, the next EAS CLI version is chosen automatically based on the existing changelog entries under the unreleased section in **CHANGELOG.md**.
