Hermes Mobile — Delivery Plan

Operational contract: Codex must read this file before each work loop. Work exactly one coherent milestone at a time. Move completed items to the completed section in the same commit that implements them. Add a concise entry to CHANGELOG.md in the same commit. Never mark work complete without running its listed verification.

Product guardrails

  • Native Android client for upstream Hermes Agent: Kotlin + Jetpack Compose.
  • Material 3 base, deliberately customized through a reusable design system.
  • Thin client: Hermes remains the authority for auth, sessions, streaming, tool semantics, and backend behavior.
  • No WebView-first app, no cloned Hermes backend, no embedded credentials.
  • Adaptive, accessible, compact-but-readable UI: phone, tablet, light/dark, font scaling, IME/keyboard, long code/output must remain safe.
  • Keep DTO/transport, domain/UI models, repositories, view models/state, and composables separated.
  • Never commit APKs, build outputs, credentials, or generated local environment files.

Release policy

  • Start artifacts at v0.1.0-beta.1.
  • Patch: compatible fixes/polish. Minor: a coherent feature milestone. Major: stable v1.0.0+ only.
  • A release requires a pushed source commit, passing relevant checks, a versioned APK artifact, and a Telegram release post.

Now — direct gateway pivot

Complete the Android/client contract pivot before implementing backend behavior. The next release path targets a remote upstream Hermes Agent gateway/API server directly; apps/companion is legacy compatibility only.

Beta path — upstream-connected MVP

  • B2 — Direct gateway connection, authentication, and local-first routing UX

    • One logical Hermes gateway profile with optional local URL + required remote fallback URL.
    • Validate URLs, store bearer/no-auth configuration securely, probe GET /health, and use optional GET /v1/models auth check.
    • Automatically prefer the local URL when reachable; immediately fail over to remote when it is not. Re-evaluate on foreground, explicit reconnect, connectivity change, and request failure; never switch a stream mid-flight.
    • Show active Local/Remote route and clear offline/unauthorized/retry state without logging tokens or silently sending credentials to untrusted LAN hosts.
    • Verification: deterministic route-selection/retry tests, connection-state tests, and manual unhappy-path walkthrough.

  • B3 — Direct gateway session contract and durable chat state

    • Fetch/list/search/select/create sessions through repository contracts after upstream session routes are verified.
    • Restore selected session and protect against duplicate sends / lost drafts.
    • Verification: fake-repository UI tests; direct gateway compatibility checks where available.

  • B4 — Direct gateway streaming, reconnects, and resilient long-running work

  • Stream event reducer: final response/token deltas first; tool lifecycle, session events, artifacts, cancel, and reconnect/backoff only where upstream capability is verified.

  • Preserve partial output and make recovery obvious and safe.

  • Verification: deterministic fake stream tests and real direct gateway exercise.

  • B5 — Tool, artifact, and output experience

    • Compact tool cards with lifecycle/status, expandable output, copy/share/save affordances.
    • Safe rendering for large logs and code; no unbounded nested scroll failures.
    • Artifact/file handoff only where upstream capability is actually supported.
    • Verification: large-output and rotation/resume checks.

Beta hardening and release

  • R1 — Adaptive/accessibility quality pass

    • Small phone, normal phone, tablet/two-pane behavior; portrait/landscape.
    • Font scaling, TalkBack semantics, contrast, touch targets, reduced motion, IME behavior.
    • Verification: emulator/device matrix evidence documented in docs/ROADMAP.md.

  • R2 — Beta packaging and install guide

    • Version v0.1.0-beta.1, reproducible debug/beta APK build, install/run guide, known limitations.
    • Publish source commit, APK, release notes, and verification result.
    • Verification: clean install on a real device or emulator plus full required checks.

V2 backlog

  • Multiple server profiles and fast switching.
  • Rich file/artifact workflows based on upstream capability.
  • Notifications for task completion.
  • Mature tablet/two-pane session + optional terminal/log pane.
  • Offline cache/search and diagnostic export with privacy controls.
  • Remove legacy companion Android routes and deprecate apps/companion install/runtime docs after direct gateway chat/session/streaming is verified.

Completed

Move finished items here with date, commit, and verification. Keep this section factual; do not claim unverified work.

  • F0 — Audit and safely land existing work — 2026-07-24, commit da79d48 (feat: land native mobile foundation).

    • Reviewed existing Android and companion edits; preserved the native Android chat/workspace/settings work and companion chat hardening.
    • Confirmed generated build outputs are ignored and added ignores for .gradle-user/ and .dev/.
    • Reconciled docs/ROADMAP.md to the actual native Android beta state and remaining validation gaps.
    • Verification: git diff --check passed; npm run typecheck --workspace @hermes-mobile/companion passed; npm run lint --workspace @hermes-mobile/companion passed; npm run build --workspace @hermes-mobile/companion passed; npm run typecheck passed; npm run lint passed; npm run build passed.
    • Android debug build attempted with GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:assembleDebug from apps/mobile/android; blocked before compilation because network socket creation is not permitted while downloading Gradle 8.11.1.

  • F1 — Compose design system extraction — 2026-07-24, commit 9ed0969 (feat: extract compose design system).

    • Extracted color, semantic status, spacing, typography, shape, elevation, and motion tokens.
    • Added light and dark Hermes Compose themes backed by Material 3 color schemes.
    • Split shared Compose cards, rows, controls, notices, message bubbles, list scaffolds, and code surfaces out of MainActivity.kt.
    • Added Compose previews for small phone, normal phone, tablet width, light theme, and dark theme component coverage.
    • Verification: git diff --check passed; GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:assembleDebug from apps/mobile/android passed.

  • F2 — Polished fake-data chat proving ground — 2026-07-24, commit f65d4ac (feat: add fake chat proving ground).

    • Added a local fake chat inbox with session rail/list, context controls, keyboard-safe composer, and send/cancel/retry interactions.
    • Added typed user, assistant, system, error, and streaming message models; selectable markdown-friendly text, horizontally scrollable copyable code, and expandable tool results.
    • Added seeded empty, loading, reconnecting, and error states plus reducer tests for send, cancel, retry, and tool expansion.
    • Verification: git diff --check passed; GRADLE_USER_HOME=/root/hermes-mobile/.gradle-user ./gradlew :app:testDebugUnitTest :app:assembleDebug from apps/mobile/android passed.

  • B1 — Transport/domain contracts — 2026-07-24, commit feat: add transport domain contracts.

    • Added transport DTOs and domain repository contracts for server profiles, authentication, sessions, messages, stream events, tool results, and artifacts.
    • Added DTO-to-domain/UI mappers, stream reducer behavior, and a fake Hermes repository for previews and unit tests.
    • Kept the companion path as an optional adapter capability without changing upstream Hermes semantics.
    • Verification: parent preflight immediately before B1 completion passed: script PASS; Android :app:assembleDebug BUILD SUCCESSFUL, 35 tasks total and 6 executed. Parent also verified git diff --check passed.

  • B2a — Direct gateway planning and compatibility contract — 2026-07-24, commit docs: pivot mobile contract to direct gateway.

    • Added docs/DIRECT_GATEWAY_ARCHITECTURE.md with documented upstream endpoints separated from unverified assumptions.
    • Reprioritized the beta path around direct gateway auth, sessions, streaming, and later companion removal.
    • Updated Android transport/domain/fake capability contracts and connection copy so new code no longer assumes a companion server.
    • Verification: git diff --check passed; Android :app:testDebugUnitTest :app:assembleDebug passed from apps/mobile/android.

Work-loop checklist

Before coding:

  1. Read PROJECT_PLAN.md, CHANGELOG.md, docs/ROADMAP.md, git status, and the prior commit.
  2. Choose the single highest-value unchecked item or a narrowly scoped sub-item.
  3. Inspect existing implementation before rewriting it.

Before committing:

  1. Run relevant checks; record exact pass/fail scope in the changelog.
  2. Update this plan: check the completed item, move it into Completed, and leave the next executable item unchecked.
  3. Add a concise CHANGELOG.md entry under Unreleased.
  4. Commit using Conventional Commits and push origin/main.
  5. Do not claim a release without an uploaded, verified versioned APK.
