Every change ships to external developers. Backward +compatibility, credential safety, and localization discipline are +non-negotiable. + +## Audience + +This skill is invoked by: + +1. **PRism** — runs as a presubmit on PRs to forcedotcom/SalesforceMobileSDK-Android. +2. **Local Claude Code sessions** — author or reviewer running `/review` against a working tree. +3. **Autonomous review agents** — multi-agent pipelines that need a Mobile-SDK-aware reviewer. + +In all three modes, the **evidence gate**, **JSON output**, and **silence-is-valid** +rules below are identical. The skill does not branch on caller. + +## The Core Question + +For each changed line, ask: +**"Which existing Mobile SDK consumer — an external app, an internal Salesforce +team, a logged-in user account, an encrypted on-device store, or a localization +pipeline — will fail or become unsafe because of this exact change?"** + +If you cannot name the old behavior, the affected consumer, and the changed +line, do not comment. + +## Evidence Gate + +Only report a finding when **all four** are true: + +1. **Old contract**: The previous behavior was part of the public SDK surface, + a documented protocol (OAuth, REST, SmartStore soup format, sync target API), + a localized string resource, or a security-relevant default. +2. **New behavior**: The PR changes that contract, default, identifier, or + security posture in a way external consumers can observe. +3. **Affected path**: You can name the caller, the persisted SmartStore data, + the locked-out user account, the missing localization, or the deployment + path that now breaks. +4. **Grounded line**: The comment is attached to an exact added/changed line + from the diff. Never invent line numbers; never cite lines outside the patch. + +**Silence is valid.** Return no findings when the diff changes behavior +intentionally but you cannot prove existing consumers are harmed. Reviewer +trust on a public SDK depends on precision — a noisy reviewer gets ignored. + +## The 8 Review Lenses + +Apply each lens to the diff. Use them as **investigation prompts**, not +permission to speculate. The evidence gate above governs every finding. + +### 1. Public-API Backward Compatibility + +The SDK follows a deprecation policy: + +- **Deprecation may be introduced in any release** (major, minor, or patch). + An `@Deprecated` annotation with a clear migration path (`message=...`, + `replaceWith=...` where possible) is sufficient at this stage — it does + **not** need to wait for a major release. +- **Removal of a deprecated symbol may only happen in a major release** + (e.g. 13.x → 14.0). Removing a deprecated symbol in a minor or patch is + always a finding. The N+2 (deprecate in N, remove in N+2) cadence is + ideal but not required — what matters is that the *removal* version is a + major. +- **Net-new breaking changes** (new public surface that is not a deprecation + cleanup — e.g. a signature change, a removed-without-prior-deprecation + symbol, a visibility downgrade) are **only allowed when the active `dev` + branch is building toward a major** (working version `X.0.0` and no `X.0` + has shipped yet). In any other state — minor cycle on `dev`, or any PR + targeting `master` — breaking changes must go through a deprecation + cycle first. + +#### Determine the current development target + +The release model uses two long-lived branches: + +- **`dev`** — active development for the next planned release (major or + minor). The version in `build.gradle.kts` reflects what `dev` is + building toward (e.g. `14.0.0` while building major 14, `14.1.0` while + building minor 14.1). +- **`master`** — what was last released, and the source for any **patch** + release. Patches are unplanned, so the version on `master` is usually + the last shipped version, not a pre-bumped patch number. PRs to + `master` are typically cherry-picks of changes already merged to `dev`, + done for the purpose of including a fix in an upcoming patch. + +Before evaluating a public-API change, determine **two** things: + +1. **Target branch of the PR**: `dev` vs. `master`. PRism passes the base + ref; locally use `git rev-parse --abbrev-ref @{upstream}` or inspect the + PR metadata. If you cannot determine the base, default to treating the + PR as targeting `dev`. +2. **Working version**: read from `build.gradle.kts` at + `allprojects { version = "X.Y.Z" }` (root), or from any library's + `rootProject.ext["PUBLISH_VERSION"]` in `libs/*/build.gradle.kts`. + +Then apply this matrix: + +| Target | Version on branch | Cycle | Net-new breaking changes | Removal of deprecated symbol | +|---|---|---|---|---| +| `dev` | `X.0.0` | Major in development | Permitted | Permitted | +| `dev` | `X.Y.0` (Y>0) | Minor in development | Not permitted — deprecate first | Not permitted | +| `master` | any | Patch (unplanned) | Not permitted | Not permitted | + +**Extra attention is required for any PR to `master`.** Patches ship +quickly and reach customers without the usual major/minor release-note +cycle. A PR to `master` should: + +- Be a cherry-pick of a change already merged to `dev` (the standard + pattern, used to avoid drift between branches). +- Contain only a bug fix or security fix — no feature work, no API + surface changes, no dependency bumps beyond what the fix requires. +- Be small and surgical relative to the corresponding `dev` commit. + +If a `master` PR is **not** a cherry-pick of an already-merged `dev` +change, flag it. If it adds or alters public API, flag it. If it includes +unrelated cleanup beyond the fix, flag it. + +Quote the target branch and the version you observed in the rationale so +the author can verify your reasoning. + +#### Look for + +- Removed, renamed, or signature-changed `public` / non-`internal` Kotlin + declarations and `public` Java members under + `libs/*/src/com/salesforce/androidsdk/`. +- Visibility downgrades on a previously public symbol (`public` → `internal`, + `protected` → `private`). +- Type changes that break source compatibility for callers (return type + narrowed, parameter type widened to a non-subtype, nullability tightened + on a non-platform type). +- Removal of `@Deprecated` symbols when the cycle does not permit removal + (i.e. `dev` not at `X.0.0`, or any PR to `master`). The age of the + deprecation is not the gate; the *release type* is. +- Annotation changes on public members (`@JvmStatic`, `@JvmOverloads`, + `@JvmField`) — these are part of the Java-interop ABI. +- Default-value or default-parameter changes on public Kotlin functions. +- A new public method or signature change without an accompanying + `@Deprecated` on the prior shape, on a branch that does not permit + net-new breaks (per the matrix above). +- Changes to `RestClient`, `SalesforceSDKManager`, `UserAccountManager`, + `SmartStore`, `SyncManager` public surfaces — these have the largest + external surface area. + +**Comment when** an external consumer's call site, override, or interop +pattern stops compiling or silently changes behavior, *and* the matrix +above says this change is not permitted at this point in the cycle. Also +comment when a `master`-targeted PR is not a cherry-pick of an +already-merged `dev` change, when it expands public API, or when it +carries unrelated cleanup. + +**Stay silent when** the symbol is `internal`, `private`, or in a +package named `internal`; when the change adds a new optional parameter +with a default; when `dev` is at `X.0.0` and the change is a documented +major-version cleanup; or when a `master` PR is a clean cherry-pick of a +fix already merged to `dev`. + +### 2. OAuth, Token, and Credential Safety + +Any change touching auth, tokens, or credential storage requires extreme care. +Per CLAUDE.md, these changes are an **escalation** — flag for human review. + +Look for: + +- Changes to OAuth2 flow construction in + `libs/SalesforceSDK/src/com/salesforce/androidsdk/auth/**`. +- Changes to `ClientManager`, `RestClient`, `OAuth2`, `TokenEndpoint`, or + identity-service classes. +- New logging that includes `accessToken`, `refreshToken`, `password`, + `consumerSecret`, `Authorization` headers, full request/response bodies, + user identifiers (org id + user id together), or PII (email, phone, name). +- Custom `OkHttpClient` instances created outside `RestClient` — `RestClient` + is the single REST entry point per CLAUDE.md. +- Hardcoded credentials, tokens, consumer keys, or callback URIs in any + source or test fixture (excluding documented sample-app consumer keys). +- New cleartext-traffic exceptions in `network_security_config*.xml` or in + `AndroidManifest.xml` (`android:usesCleartextTraffic="true"`). +- Removal of token-refresh, 401-retry, or session-revocation handling. +- Changes to QR-code login that weaken consumer-key validation. + +**Comment when** a credential can leak through logs, persistence, or network; +when an auth flow stops verifying server identity; or when a fix to the auth +state machine drops a previously handled error path. + +**Stay silent when** logs reference auth events without payload (e.g. +`"refreshing token"` with no token value); when the change is purely +internal restructure with no observable security-relevant effect. + +### 3. SQLCipher / SmartStore Encryption + +SmartStore depends on SQLCipher (`net.zetetic:sqlcipher-android`) for at-rest +encryption. Per CLAUDE.md, SQLCipher integration changes are an +**escalation**. + +Look for: + +- Changes to SQLCipher version in `libs/SmartStore/build.gradle.kts` (the + `update-sqlcipher` skill in `.claude/skills/update-sqlcipher/SKILL.md` + documents the full update process — flag if that process appears + incomplete: missing test version updates, missing API-change handling). +- Changes to `DBOpenHelper`, `DBHelper`, or `SmartStore` class encryption-key + retrieval, key-rotation logic, or `DatabaseErrorHandler` implementations. +- New paths where the SQLCipher key or encryption passphrase is logged, + serialized, or passed across process boundaries. +- Removal or weakening of `KeyStoreWrapper` / `Encryptor` integration with + the Android Keystore. +- Soup-format changes (index spec types, soup name schema) that break + on-device data written by an older app version — SmartStore upgrades + must preserve existing user data. +- SQLCipher migration code that opens a database without first checking for + the existing on-device version. + +**Comment when** a user's encrypted store could become unreadable after the +upgrade, when the encryption key path is weakened, or when the SQLCipher +update is missing the canonical updates documented in the +`update-sqlcipher` skill. + +**Stay silent when** the change is a pure SmartStore feature addition that +extends the public API additively without touching key handling or +on-disk format. + +### 4. Multi-User Account Correctness + +The SDK supports multiple logged-in accounts simultaneously. Single-user +assumptions are a recurring class of bug. + +Look for: + +- New static / singleton state in `SalesforceSDKManager`, `RestClient`, + `UserAccountManager`, `MobileSyncSDKManager`, sync managers, or SmartStore + managers that does not key off the current `UserAccount`. +- Code that reads "the current user" without handling the multi-user-pending + case (no current user during account switch). +- File / SharedPreferences / SmartStore / cache paths that omit the user-id + or org-id segment, leading to data bleed between accounts. +- Push-notification registration or unregistration that ignores the account + it was registered for. +- Cleanup paths on logout that don't scope to the user being logged out. + +**Comment when** account-switching, simultaneous multi-user use, or logout +of one of N users will produce wrong-user data, leaked tokens, or stale +caches. + +**Stay silent when** the code path is documented as single-user (e.g. +hybrid bridge during initial bootstrap) and the diff stays within that +constraint. + +### 5. Localization (`sf__strings.xml`) + +Per CLAUDE.md, all new user-facing strings must go in `sf__strings.xml` with +the `sf__` prefix. Localization is an **escalation** — any `sf__strings.xml` +change requires human attention. + +Look for: + +- Hardcoded user-facing strings in Kotlin/Java/Compose UI files + (`Toast.makeText`, `setText`, `Text(...)`, `AlertDialog.setMessage`, etc.) + that are not pulled from resources. +- New `` entries inside `sf__strings.xml` whose key does + not start with `sf__`. The `sf__` prefix is required for keys defined in + that file. +- Changes to existing translated `` values (the *value*, not the key) + without an accompanying note about re-translation. The English value in + `sf__strings.xml` is the source-of-truth that drives localization for all + other locales — silently changing it leaves other locales out of date. +- Removal of string keys that may still be referenced by external apps that + ship their own translations. + +**Comment when** a new user-visible string is hardcoded, when an `sf__`- +prefixed key value changes without a re-translation note, or when a key +is deleted that may be in use externally. + +**Stay silent when** the string is a log message, exception message intended +for developers, or a constant that is never displayed to users. + +### 6. Android Platform Hygiene + +Look for: + +- New Java files. Per CLAUDE.md, **no new Java files** — Kotlin only. +- Force-unwraps (`!!`) introduced without a comment justifying why null is + impossible at that line. Force-unwraps in `init`, `lateinit`, or after a + proven null check are typically fine but should be avoided when possible. +- Blocking work on the main thread: `Thread.sleep`, `runBlocking` on the + main dispatcher, synchronous network calls (`okhttp3.Call.execute()` + outside a worker dispatcher), file I/O on `Dispatchers.Main`. +- New callback-based public APIs when an existing pattern uses suspending + functions — per CLAUDE.md, callbacks are being deprecated in favor of + coroutines. +- Use of legacy support libraries (`android.support.*`) — should be `androidx.*`. +- New `` entries in `AndroidManifest.xml`. Per CLAUDE.md, + Android permission changes are an **escalation**. +- `targetSdk` / `compileSdk` / `minSdk` changes in any `build.gradle.kts`. + Per CLAUDE.md, build-system changes are an **escalation**. +- Deprecation warnings introduced (calls to `@Deprecated` Android APIs, + Kotlin language deprecations). +- New third-party dependencies in `build.gradle.kts` files. Per CLAUDE.md, + new dependencies are an **escalation** (license/security review needed). + +**Comment when** a change introduces blocking main-thread work, ignores the +no-new-Java rule, adds a permission, or bumps an SDK target. + +**Stay silent when** the pattern matches surrounding code (e.g. a `!!` in a +file that uses `!!` throughout, where forcing a switch is out of scope) — +flag the broader pattern only if it crosses into one of the higher-severity +lenses above. + +### 7. Sample Apps & API Contracts + +When public SDK API changes, sample apps under `native/NativeSampleApps/**` +and `hybrid/HybridSampleApps/**` are part of the contract — they're how +external developers learn the SDK. + +Look for: + +- Public-API changes that don't have a corresponding sample-app update. +- Sample-app changes that introduce patterns the SDK itself doesn't endorse + (raw `OkHttpClient`, hardcoded credentials beyond the documented + consumer-key constants, swallowed exceptions in flagship samples). + +**Comment when** a public-API change is not reflected in samples or when a +sample establishes a counter-example to SDK guidance. + +**Stay silent when** the sample-app change is a cosmetic fix unrelated to +SDK behavior. + +### 8. Test Correctness & Coverage + +Tests are part of the SDK contract. A test whose body does not match its +name, asserts on the wrong value, or silently passes when the SUT is +broken is **worse than no test** — it gives false confidence and survives +regressions. Test code under `libs/test/**`, `**/test/**`, `**/androidTest/**` +is in scope and reviewed with the same rigor as production code. + +Look for: + +- **Name vs. body mismatch**. The CLAUDE.md naming convention is + `test_given[Precondition]_when[Action]_then[Expected]`. Verify: + - The "given" matches the test's `@Before` / setup state and any + test-local arrangement. + - The "when" matches the single action under test. + - The "then" matches what the assertions actually verify. + Names that lie (e.g. `test_givenExpiredToken_whenRefresh_thenRetries` + but the body never expires the token, or asserts only on a return value + that is the same whether the token is fresh or expired) are findings. + (Test-name lies are a specialization of the cross-cutting "Comments + That Lie" principle below — apply that section's rules.) +- **Assertions that pass vacuously**. + - `assertNotNull(result)` where `result` is constructed by the test + itself or returned by a non-null platform type. + - `assertTrue(list.size >= 0)` and similar always-true predicates. + - `assertEquals(expected, expected)` — both sides reference the same + fixture, not the SUT output. + - Catching `Exception` in a test body and asserting nothing — the test + passes even if the SUT throws unexpectedly. +- **Missing assertions**. A test that calls the SUT but contains zero + `assert*` / `verify*` / `Espresso onView(...).check(...)` calls is + asserting nothing. +- **Mocking the class under test**. Per CLAUDE.md, mock boundaries + (network, keystore, SQLCipher, system services), not the SUT. Flag + `mock(SalesforceSDKManager::class.java)` inside a `SalesforceSDKManager` + test, or `Mockito.spy(sut)` followed by `when(sut.method())...` that + stubs the very behavior under test. +- **Determinism violations**. `Thread.sleep`, hardcoded delays, + `System.currentTimeMillis()` used without injection, real network calls, + ordering assumptions in `HashMap` / `HashSet` iteration. CLAUDE.md + forbids flaky tests; Espresso idling resources and proper + synchronization are required. +- **Cleanup gaps**. A test that creates a soup, account, or cached file + without an `@After` that removes it. State bleeds into the next test + and produces order-dependent passes. +- **Coverage regressions on changed code**. When the diff modifies a + public method but does not add or update a test that exercises the new + behavior, flag it. New behavior without test coverage is a finding. +- **Test data with credentials**. Real OAuth tokens, real consumer keys, + real PII in test fixtures. Use `test_credentials.json` in `shared/test/` + per CLAUDE.md. + +**Comment when** the test name or assertions don't match what the body +actually verifies; when the SUT is mocked; when assertions are vacuous; +when new public behavior lands without a test; when the test is +flaky-by-construction; or when test data contains real credentials. +For lying comments inside test bodies, apply the "Comments That Lie" +section. + +**Stay silent when** the test is a straightforward addition that exercises +the SUT through its public API, asserts on observable outcomes, and +matches the naming convention even if not perfectly. Style preferences +(BDD vs. test_method form, Hamcrest vs. JUnit assertions) are out of +scope unless they cross into one of the failure modes above. + +#### How to read a test + +For each changed test method, in order: + +1. Read the test name and any leading comments. State, in your head, what + precondition + action + expected outcome they imply. +2. Read the `@Before` and any setup helpers. Note what state is actually + established. +3. Read the body. Identify the single line that invokes the SUT. +4. Read the assertions. Identify what each one actually checks. +5. Compare 1 vs. 2+3+4. If they don't line up, that's the finding. + +Quote both the test name (or comment) and the contradicting body line in +the rationale. + +## Where to Comment + +Prefer the line where the breakage is **experienced**, not where it +originates: + +- A renamed `RestClient` method breaks an external consumer's call site: + comment on the rename and name affected callers in the rationale. +- A SmartStore index-type change breaks a soup migration: comment on the + migration line, or on the index-spec line and explain the data-path break. +- A new hardcoded string in a Compose screen: comment on the literal, not + the function declaration. + +Do not leave duplicate comments for the same root cause. Choose the clearest +line and write one finding. + +## Confidence Threshold + +This skill runs at `level: 'warn'`. Author trust is preserved by precision — +warnings cost reviewer attention even when they are not blocking. + +- Default emission is **`severity: warning`** at **confidence 7.0 – 10.0**. +- Reserve **`severity: blocker`** with **confidence 9.0 – 10.0** for cases + where a merged regression is catastrophic and unrecoverable: + - A credential / token / refresh-token leak path with a concrete log, + persistence, or network sink the diff demonstrably introduces. + - A SQLCipher key path that becomes unauthenticated, or a SmartStore + migration that the diff proves will corrupt or delete existing + encrypted user data on upgrade. + - Real credentials, real OAuth tokens, real consumer secrets, or real + user PII committed in a test fixture or test source file. Once + public-history, the secret must be rotated. +- All other escalations (removed `@Deprecated` symbol, weakened multi-user + scoping, unflagged public-API change, missing localization, etc.) emit + as `severity: warning` with high confidence. The rationale text should + call out the CLAUDE.md "escalation" status in prose — that is the + appropriate signal under `level: warn`. +- Do not emit findings below confidence 7.0. Stay silent. + +## Output Format + +For each finding, return: + +```json +{ + "is_blocking": false, + "rationale": "In `libs/SalesforceSDK/src/com/salesforce/androidsdk/rest/RestClient.kt:142`: `RestClient.sendSync()` was made `internal`, but it was a public API as of 12.2 and is referenced from sample app `RestExplorer/MainActivity.kt:88`. External apps that follow that pattern will fail to compile against the new SDK.

Lens 8 + covers test correctness; do not also flag the same test under another + lens unless the test is itself a public API (e.g. a public test + utility under `libs/test/SalesforceSDKTest/.../TestUtils.kt` whose + signature changed). +- Documentation-only changes (`*.md`, KDoc comments) unless the doc change + contradicts the diffed code. +- Intentional cleanup, deleted dead code, or removed already-deprecated + behavior whose deprecation period has demonstrably elapsed. +- Generic "missing validation", "consider adding error handling", or "may + break" concerns without a named affected path. +- Style or pattern preferences that the surrounding file already violates — + flag the broader pattern only via lens 6 if it rises to a real bug. +- The `update-sqlcipher` and `update-min-sdk` skills' subject matter when + the PR is invoking those skills — they are documented operational changes, + not novel risk surfaces. Flag only if those skills' checklists are not + fully satisfied. + +## Deletions Are Clues, Not Findings + +Removed code deserves attention, but deletion alone is not a defect. Before +commenting on a deletion: + +- Verify what still depends on the removed behavior in this repo. +- Check whether the PR replaced the behavior elsewhere. +- If the code was deprecated past two majors, unused, or intentionally + superseded, **stay silent**. + +## Comments That Lie + +This rule applies to **every lens** and to **every file in the diff** — +production Kotlin, Java, XML, Gradle, sample apps, *and* test code. A +comment, KDoc, Javadoc, or doc string that contradicts the code it +annotates is a finding regardless of where it appears. + +Why it matters on a public SDK: external developers read SDK source and +KDoc to learn the API. A comment that says "refreshes the token on 401" +above a method that no longer handles 401 will be propagated into +external apps as an incorrect assumption. Stale comments age into bugs. + +Look for: + +- **KDoc / Javadoc that describes a method's old contract.** Example: + `/** Returns null if the user is not logged in. */` above a method + whose new body throws or returns a sentinel object instead. +- **Inline comments contradicting the surrounding statements.** Example: + `// Skip refresh if token is fresh` above a branch that refreshes + unconditionally; or `// Run on background thread` above a call that + now executes on `Dispatchers.Main`. +- **`@param`, `@return`, `@throws` tags** that no longer match the + current signature, return type, or thrown exceptions. +- **`TODO` / `FIXME` / `XXX`** referencing a constraint that has been + resolved by the diff (e.g. `// TODO: remove when min API >= 28` + surviving into a min-SDK 28 commit). +- **Header banners and copyright/version notices** that name an API + version, year, or author no longer accurate after the change. +- **Sample-app comments** ("// Replace with your consumer key") that + have been bypassed because the consumer key is now hardcoded to a real + value — the comment lies *and* there is a credential leak. +- **Test names and inline comments** describing behavior the body does + not exercise (covered as a specialization in lens 8). + +How to evaluate: + +1. For each modified region, scan the comments inside and immediately + above it. +2. Check whether the comment's claim is still true in the post-diff code. +3.
