bat-code Implementation Plan

Batman-themed AI coding TUI. Package at libs/batman-cli/, CLI command bat-code. Architecture: Custom Textual UI (Option B, stranger-code style) + local editable deepagents SDK.

Phase 0 — Scaffold Package

Create libs/batman-cli/ directory
Write libs/batman-cli/pyproject.toml
- Build system: hatchling
- Package name: batman-cli
- Entry point: bat-code = "batman_code:cli_main"
- Dependencies: mirror libs/cli/pyproject.toml (textual, langchain, etc.)
- [tool.uv.sources] deepagents pointing to ../deepagents editable
- Optional extras: all model providers (anthropic, openai, etc.)
Create libs/batman-cli/batman_code/ package directory
Write batman_code/__init__.py — export __version__, cli_main
Write batman_code/__main__.py — python -m batman_code support
Write batman_code/_version.py — version 0.1.0
Run uv sync in libs/batman-cli/ to verify scaffold installs cleanly
Verify bat-code --help runs without error

Phase 1 — Config & Color System — COMPLETE

Write batman_code/config.py
- Batman color palette constants (COLORS dict):
  - background: #0a0a0f
  - bat_gold: #f5c518
  - gotham_blue: #1a3a5c
  - error: #8b0000
  - success: #00ff41
  - tool: #2d2d4e
  - dim: #4a4a6a
  - user: #e8e8e8
- Glyphs frozen dataclass (same fields as deepagents_cli, bat-themed defaults)
  - spinner_frames: bat-wing frames ["(\\ )", "( \\ )", "( / )", "(/ )"] cycling
  - bat_symbol: ">==|==<" compact bat, and full ASCII bat for overlays
- CharsetMode StrEnum (UNICODE / ASCII / AUTO)
- Settings frozen dataclass with env var loading
- get_glyphs() cached function
- get_banner() — returns Gotham ASCII art banner text
- PERSONA_NAMES list: ["batman", "alfred", "oracle", "nightwing", "joker"]
- DEFAULT_PERSONA = "batman"
Write batman_code/app.tcss
- All color variables using Batman palette
- Screen layer definitions (base, autocomplete, batsignal)
- #chat, #messages, #bottom-app-container, #input-area layout
- .approval-menu with bat-gold border
- Message type styling:
  - User: white text, thin white border
  - Assistant: bat-gold left border
  - Tool: dim violet background
  - Error: dark red border
  - System: gotham blue border
- Status bar color coding:
  - DETECTIVE MODE: #1a3a5c (gotham blue)
  - DARK KNIGHT MODE: #8b0000 (danger red)
- Bat-signal overlay layer (#batsignal-overlay)

Phase 2 — Model & Session Infrastructure — COMPLETE

Near-direct ports from libs/cli/deepagents_cli/ with Batman naming. All deepagents_cli.* imports remapped to batman_code.*. SDK imports (deepagents.*) kept as-is. Two deferred imports remained until Phase 4 — resolved in commit 8842309; the tracking doc was removed once closed (see git history / archive).

Phase 3 — Agent Personas — COMPLETE

Write batman_code/system_prompt.md
- Ported from deepagents_cli/system_prompt.md (240 lines)
- Branding: "Deep Agents CLI" → "Bat-Code", "Deep Agent" → "Bat-Code agent"
- Added {persona_instructions} placeholder for runtime injection
- All safety rails (git, security, debugging) kept verbatim
Write batman_code/prompts/__init__.py
- load_persona(name) utility — reads persona .md by name
Write batman_code/prompts/batman.md
- Terse, imperative, Detective Mode debugging, max 2 sentences
- Easter eggs: "why so serious?" → ., "who are you?" → "I'm Batman."
Write batman_code/prompts/alfred.md
- Refined British butler, verbose, "If I may, sir...", dry wit
- Easter eggs: "where's Bruce?" → "Master Wayne is... indisposed."
Write batman_code/prompts/oracle.md
- Analytical hacker, mission briefing format (Situation/Analysis/Recommended action)
- Easter eggs: "birds of prey" → 🙄, security vuln → "Backdoor detected."
Write batman_code/prompts/nightwing.md
- Collaborative, witty, pair programming energy, "we" and "let's"
- Easter eggs: Haley's Circus refs, "Stuck the landing! Perfect 10."
Write batman_code/prompts/joker.md
- Chaotic, theatrical, DARK KNIGHT MODE (auto-approve)
- Startup warning text defined, roasts bad code dramatically
- Easter eggs: "why so serious?" → unhinged semicolons monologue

Phase 4 — Agent Wiring — COMPLETE

Plan: tasks/phase4-plan.md 4 commits: config prereq → agent.py → ui.py + input.py → deferred import fixups

Add "primary_dev": "#e0a800" to COLORS dict in config.py
- Prerequisite for ui.py's show_help() editable-install banner
Write batman_code/agent.py — port from deepagents_cli/agent.py
- DEFAULT_AGENT_NAME = "agent" (unchanged)
- list_agents() — ~/.deepagents/ → ~/.bat-code/ in empty-state text
- reset_agent() — no changes (uses settings.user_deepagents_dir)
- get_system_prompt(assistant_id, sandbox_type, persona="batman") — adds persona injection via .replace("{persona_instructions}", load_persona(persona))
- Skills path: ~/.deepagents/ → ~/.bat-code/
- create_batman_agent() — mirrors create_cli_agent + persona kwarg
  - Joker enforcement: if persona == "joker": auto_approve = True
  - Temp dir prefixes: deepagents_ → batcode_
- All deepagents_cli.* imports → batman_code.*
- New import: from batman_code.prompts import load_persona
- All _format_*_description and _add_interrupt_on helpers ported verbatim
Write batman_code/ui.py — port from deepagents_cli/ui.py
- Verbatim: build_help_parent, _format_timeout, truncate_value, format_tool_display, format_tool_message_content
- show_help(): deepagents → bat-code, -a/--agent → -p/--persona, --auto-approve → DARK KNIGHT MODE
- All show_*_help(): deepagents → bat-code, ~/.deepagents/ → ~/.bat-code/
- All deepagents_cli.* imports → batman_code.*
Write batman_code/input.py — port from deepagents_cli/input.py
- Near-direct port: only import paths change
- INPUT_HIGHLIGHT_PATTERN already matches /batsignal generically
- No /batsignal registration needed (deferred to Phase 7/8)
Resolve deferred import in batman_code/non_interactive.py
- from deepagents_cli.agent import DEFAULT_AGENT_NAME, create_cli_agent → from batman_code.agent import DEFAULT_AGENT_NAME, create_batman_agent
- Rename create_cli_agent(...) calls → create_batman_agent(...)
Resolve deferred import in batman_code/skills/commands.py
- from deepagents_cli.ui import ... → from batman_code.ui import ...
Close out deferred-imports tracking — all items resolved (the standalone tasks/deferred-imports.md was kept while items were open and removed in the Phase 5 docs cleanup once fully closed)

Phase 5 — Core Widgets — COMPLETE

Phase 6 — Batcave Splash Screen (Multi-Phase)

Phase 6a — "BAT CODE" Block-Letter Glitch Animation — COMPLETE

batman_code/widgets/batcave.py — BatcaveScreen(Screen[None])
- Skippable: any keypress skips to settled state; second keypress dismisses
- --no-splash flag dismisses immediately
10-row-tall block letters using █╔═╗║╚╝ box-drawing chars
- ~99 chars wide, centered horizontally and vertically on screen
- 10-shade gold gradient (_FACE_SHADES), letter gap 2, word gap 5
Per-cell smooth settling with _MatCell dataclass
- Delay 2-7 ticks, settle 8-16 ticks
- Character cycling decelerates with progress
- Color lerps from dark-blue glitch → bat-gold via progress^1.5
Portrait feature explored and descoped — all portrait code, assets, and tools removed
User testing — glitch animation approved
Committed, pushed, and merged to main

Phase 6b — Batcomputer CRT + Typewriter — COMPLETE

Phase 7 — Bat-Signal Widget — COMPLETE

Full plan: see tasks/archive/phase7-plan.md (archived on close). This checklist mirrors that doc's per-commit shape with check-offs added per commit.

Batch 13 — `/batsignal` core — 4 of 4 landed

feat(batman-cli): add BatSignalOverlay widget with flicker animation (e7bf09e)
- New file batman_code/widgets/batsignal.py:
  - BAT_SYMBOL_ASCII constant (7-line bat symbol from CLAUDE.md Phase 1 spec)
  - _FLICKER_COLORS = {"dim": "#2d2d2d", "normal": "#b8960c", "bright": "#f5c518"}
  - _FLICKER_STATES = ("dim", "normal", "bright", "off") — includes rare "off" state for the blank-frame spotlight flicker effect
  - _FLICKER_INTERVAL_RANGE = (0.3, 1.5) seconds
  - class BatSignalOverlay(Widget) — set_interval loop calls _flicker() which picks a new state + reschedules with a jittered interval. render() returns colored Text or empty string when state == "off".
  - Pure helpers _pick_next_state() and _next_interval() extracted as testable seams (mirrors the _build_title() pattern from model_selector / thread_selector).
- No re-export from widgets/__init__.py — deep import per source convention (matches approval.py, autocomplete.py, thread_selector.py).
- Bundled unit tests (if <30 LOC per tasks/lessons.md): _pick_next_state() returns a valid state, _next_interval() stays in [0.3, 1.5], render() colors match state, ASCII constant is exactly the spec's 7-line string.
feat(batman-cli): wire /batsignal command dispatch + autocomplete (96f75b2)
- widgets/autocomplete.py::SLASH_COMMANDS — append 13th entry ("/batsignal", "Toggle bat-signal overlay").
- app.py:
  - Import BatSignalOverlay from batman_code.widgets.batsignal.
  - Add self._batsignal_overlay: BatSignalOverlay | None = None to BatmanApp.__init__. No separate _batsignal_active bool — the widget reference is the state (None = off, else = on). Simpler + avoids drift.
  - Add elif branch to _handle_command: elif cmd == "/batsignal": await self._toggle_batsignal(command).
  - Implement _toggle_batsignal(command: str):
    - Mount UserMessage(command) first (sibling handler pattern).
    - If overlay is None → create + mount to Screen + confirm with themed AppMessage("Bat-signal engaged.") (or similar — confirm exact wording at commit review).
    - Else → await self._batsignal_overlay.remove(), null the reference, confirm with themed AppMessage("Bat-signal stood down.").
  - Await .remove() before nulling to avoid a double-toggle race leaking an overlay.
test(batman-cli): cover /batsignal wiring + autocomplete registration (a422c38)
- New tests/widgets/test_autocomplete.py (autocomplete.py was deep-import verbatim in Phase 5 — first test file for it):
  - /batsignal present in SLASH_COMMANDS with the exact description
  - SLASH_COMMANDS length is 13 (regression against accidental entry removal)
- Extend tests/test_app.py:
  - _handle_command source contains "/batsignal" + _toggle_batsignal call
  - _toggle_batsignal source contains the themed AppMessage strings ("Bat-signal engaged." + "Bat-signal stood down.") — regression guards for wording
  - BatmanApp.__init__ initializes _batsignal_overlay to None (source-inspection check, matches the pattern for other kw-only param defaults in test_app.py)
docs: mark Phase 7 COMPLETE (this commit)
- Bumps this checklist (Phase 7 header → COMPLETE, Batch 13 → 4 of 4, all commits checked off with hashes).
- Bumps tasks/phase7-plan.md status banner to COMPLETE with final commit range + total tally. Plan doc moved to tasks/archive/phase7-plan.md (matches Phase 5/8/9 archive pattern).
- Updates tasks/archive/README.md with the Phase 7 row + close-out commit hash.
- Updates MEMORY.md topic files:
  - project_status.md: [x] Phase 7: Bat-Signal Overlay — COMPLETE; marks Phase 10 (end-to-end verification) as NEXT.
  - project_deferred_work.md: /batsignal core section removed (it's shipped); easter-eggs backlog stays under its own heading.
  - project_key_files.md: adds widgets/batsignal.py + tests/widgets/test_batsignal.py + tests/widgets/ test_autocomplete.py entries.
  - MEMORY.md index one-liners refreshed where Phase 7 status is mentioned.

Phase 7 tally: 4 commits (e7bf09e..<this>), 28 new tests (15 widget + 13 wiring), 316 tests passing across the suite, zero deepagents_cli references in source (only remaining deepagents.* refs are SDK imports).

Out of scope (parked for future planning)

Easter eggs: villain-of-the-day, Gotham weather status slot, additional loading screens, additional slash commands. These stay in tasks/deferred.md under "Easter eggs backlog" — to be planned collaboratively once /batsignal core lands.

Phase 8 — Textual Adapter & Main App — COMPLETE

Full plan: see tasks/archive/phase8-plan.md (archived on close). This checklist mirrors that doc's per-commit shape with check-offs added per commit.

Batch 10 — `textual_adapter.py` (895 LOC) — COMPLETE

feat(batman-cli): port textual_adapter.py (verbatim) (8a5de62)
- 5 import remaps applied: deepagents_cli.{file_ops, image_utils, input, ui, widgets.messages} → batman_code.*
- Zero behavioral changes; theming deferred to commit 3
test(batman-cli): cover textual_adapter.py pure-logic helpers (4504f8c)
- 25 tests covering _build_stream_config, _is_summarization_chunk, _build_interrupted_ai_message, TextualUIAdapter.__init__ / set_token_tracker, _HITL_REQUEST_ADAPTER smoke check
feat(batman-cli): theme textual_adapter.py narrative strings (95fda97, theming + 3 regression tests bundled per lessons.md <30-LOC rule)
- "Thinking" → "Investigating" (DETECTIVE MODE voice)
- "Interrupted by user" → "Mission aborted." (cinematic)
- "Command rejected. Tell the agent what you'd like instead." → "Order denied. Tell the Dark Knight what to do instead." (DARK KNIGHT MODE branding, instructive guidance preserved)
- Regression tests use inspect.getsource(execute_task_textual) to assert themed strings present + upstream strings gone
Suite: 164 passed (3 batch-10 commits + 136 Phase 5).

Batch 11 — `app.py` (2094 LOC)

feat(batman-cli): port app.py (verbatim with import remaps) — single 2094-LOC commit (matches Batch 3 messages.py shape)
- All deepagents_cli.* → batman_code.* (~15 top-level + 1 inline _version import statement at the /version handler)
- from deepagents_cli.agent import create_cli_agent → from batman_code.agent import create_batman_agent (incl. line 1943 call site + the comment at line 1932)
- DeepAgentsApp class name → BatmanApp (incl. the run_textual_app constructor call site)
- _COMMAND_URLS dict: changelog / feedback → https://github.com/Akhan521/bat-code/... URLs. /docs keeps DOCS_URL constant (sourced from config). Correctness fix bundled with port, same pattern as Batch 9 chat_input history path.
- Approved deviation from pure verbatim: BatmanApp.__init__ accepts no_splash: bool = False (kw-only) and stores it as self._no_splash. Required because the pre-existing Phase 1 main.py stub calls BatmanApp(no_splash=args.no_splash); without this param, runtime breaks. The on_mount conditional push of BatcaveScreen deliberately stays out of commit 1 and lands in commit 3 alongside the joker modal (both are new on_mount behaviors). Temporary regression: splash won't render at runtime between commits 1 and 3 — accepted because CLI isn't end-to-end usable until Phase 9 anyway.
- No theming, no logic changes, no new on_mount behavior beyond the no_splash storage above.
test(batman-cli): cover app.py pure-logic helpers (46fe383)
- 40 unit tests in tests/test_app.py covering: QueuedMessage (frozen, fields, equality, all 3 InputMode literal values); TextualTokenTracker (add accumulates + notifies, overwrites previous, reset zeroes, hide is no-op without callback, show replays current_context); TextualSessionState (defaults, auto_ approve persistence, reset_thread generates distinct 8-char hex, auto_approve survives reset); _COMMAND_URLS integrity (three keys, bat-code repo URLs with regression guards against rollback, /docs delegates to DOCS_URL); _build_thread_message async URL resolver (Rich Text on success, plain str on None or exception); BatmanApp.__init__ (no_splash defaults False + explicit value preserved, all other storage defaults, cwd path handling, tools falsy → empty list, MessageStore + deques start empty); module- level smoke (REMEMBER_PROMPT size check, InputMode literal values).
- Suite: 204 passed (40 new + 28 textual_adapter + 136 Phase 5).
Commit 3 SPLIT into 3 sub-commits per small-commit convention (all applied concerns from the "BIG commit" scope below):

New on_mount behavior (NOT in source):
- Splash mount: add from batman_code.widgets.batcave import BatcaveScreen import. In on_mount, conditionally push BatcaveScreen(no_splash=self._no_splash) early (before agent / adapter wiring). No exit callback — the splash should dismiss to reveal the chat UI, NOT exit the app (different behavior from the Phase 1 demo stub which exited on dismiss because there was nothing else to show).
- Joker startup warning modal (NEW): add persona: str = "batman" kw-only param to BatmanApp.__init__ (stored as self._persona); on_mount pushes themed modal when persona == "joker" (after splash, before chat focus). Both conditional pushes are unit-testable seams.
Theming — narrative strings (chrome → Gotham voice):
- App TITLE class variable "Deep Agents" → "bat-code" (line 353)
- Help text command-list intro + footer (lines 1087-1101) — Gotham voice; slash names + key-binding mnemonics stay functional
- /version output strings (lines 1112, 1115): "deepagents version: {ver}" and "deepagents version: unknown" → themed wording
- Status messages: "Switched to ..." (1972) / "Resumed thread ..." (via _build_thread_message) / "No active session" (1048) / "Unknown command:" (1202) / "Already using ..." (1898) / "Started new thread: ..." (1133) / "Already on thread: ..." (1794) / "Failed to switch to thread ..." (1850) → themed
- Error messages: "Model not configured" (n/a — that's a phantom; the real strings are "Agent not configured." 1250, "Failed to create model: ..." 1928, "Model switch failed: ..." 1958, "Could not save model preference." 1915, "Could not save default model. Check permissions for ~/.deepagents/" 2016, "Could not clear default model. Check permissions for ~/.deepagents/" 2037, "Cannot switch threads: no active agent" 1782, "Cannot switch threads: no active session" 1788, "Missing credentials: ..." 1890) → themed
- Auto-approved shell command notice (line 829): "✓ Auto-approved shell command (allow-list): {cmd}" → themed
- Model-preference saved-but-restart notice (line 1908): "Model preference set to ... Restart the CLI for the change to take effect." → themed
- LangSmith tracing hint (line 1062): "LangSmith tracing is not configured. Set LANGSMITH_API_KEY and LANGSMITH_TRACING=true to enable." → themed (instructive parts kept)
- _COMMAND_URLS usage flow note: Usage: /model --default provider:model (line 1190) — functional, keep verbatim
- "Command completed (no output)" (line 976) → themed
- Approval-mode toggle confirmations mirror StatusBar's "DETECTIVE MODE" / "DARK KNIGHT MODE" labels (already themed in Phase 5)
- "Press Ctrl+C again to quit" notification (line 1593) → themed
- Resume-thread label: "Resumed thread" prefix passed to _build_thread_message (line 1431) → themed
Path correctness (currently still says ~/.deepagents/):
- 5 occurrences in error messages: lines 1888, 1916, 1977, 2016, 2037 → ~/.bat-code/
- 3 occurrences in REMEMBER_PROMPT (lines ~265, 266, 284): ~/.deepagents/agent/AGENTS.md, .deepagents/AGENTS.md, ~/.deepagents/agent/skills/ → ~/.bat-code/...
- REMEMBER_PROMPT is an agent prompt, NOT chrome — keep substance intact; only swap deepagents-cli / ~/.deepagents/ references.
Docstring updates (self-identifies file as bat-code, not deepagents):
- Line 1 module docstring: """Textual UI application for deepagents-cli.""" → """...for bat-code."""
- Line 351 class docstring: """Main Textual application for deepagents-cli.""" → """...for bat-code."""
- Line 409 init docstring: """Initialize the Deep Agents application.""" → themed (e.g. """Initialize the bat-code application.""")
UserMessage theming touch in widgets/messages.py (Phase 5 follow-up bundled here):
- Border-left + > prefix #10b981 → COLORS["gotham_blue"] (#1a3a5c)
- Add "Gotham Citizen:" label above content in compose layout (closes CLAUDE.md Phase 1 spec item Phase 5 deferred)
feat(batman-cli): add on_mount splash + joker modal behavior (84098a0)
- BatcaveScreen import added
- persona: str = "batman" kw-only param + self._persona storage
- JokerWarningModal(ModalScreen[None]) class defined inline with "⚠ DARK KNIGHT MODE ENGAGED" title + "Chaos incoming" body per user-selected "Dramatic" wording; any key dismisses
- on_mount pushes JokerWarningModal (bottom of stack) if persona=="joker", then BatcaveScreen (top of stack) if not no_splash
- No exit callback on BatcaveScreen — full Phase 8 reveals chat after splash dismisses (unlike Phase 1 demo stub which exited)
feat(batman-cli): theme app.py with Gotham language + bat-code paths (b307c67)
- Group B narrative theming: TITLE, docstrings, /version, help text with Batcomputer/DARK KNIGHT MODE/THE CAVE labels, all status confirmations (New case opened, Batcomputer deployed, Case reopened, etc.), Villain detected error prefix, Ctrl+C Batcave hint, Unrecognized Batcomputer command, No active patrol, Auto-authorized (Batcave allow-list), Mission complete
- Group C path corrections: 5 error-message paths + 3 REMEMBER_PROMPT paths → ~/.bat-code/
- Only remaining deepagents refs: SDK imports from deepagents.backends import ... (unchanged — first-party dep of the deepagents package, not deepagents-cli)
feat(batman-cli): theme UserMessage with Gotham Citizen sender label (50b5f82)
- Border-left + ASCII fallback + > prefix colors all #10b981 → #1a3a5c (gotham_blue)
- "Gotham Citizen:\n" prepended above the > content line
- QueuedUserMessage untouched (its grey styling is intentional "queued while agent runs" ephemeral state)
test(batman-cli): cover app.py + messages.py Batch 11 theming (ef567d2)
- 39 new theming regression tests appended to tests/test_app.py using inspect.getsource(...) pattern (same as Batch 10)
- Covers TITLE, docstrings, /version, REMEMBER_PROMPT paths, all themed method bodies (help text, bash notice, auto-approve notice, agent lifecycle, case/thread vocabulary, model switching), persona defaults + on_mount conditional pushes, JokerWarningModal class + title + body, UserMessage border color + Gotham Citizen label + prefix styling
- Suite: 243 passed (39 new + 204 prior)
docs: mark Phase 8 COMPLETE — bumps this checklist + phase8-plan.md scope table + MEMORY.md next-session pointer (moves on to Phase 9 — main.py CLI entry)

Splash mount details (decision locked at planning)

BatmanApp.__init__ accepts no_splash: bool = False. Param + storage shipped in commit 1. Conditional on_mount push of BatcaveScreen (the actual rendering behavior) ships in commit 3 alongside joker modal — both are new on_mount behaviors and bundle cleanly together. Phase 1 demo stub used to self.push_screen( BatcaveScreen(...), callback=lambda _: self.exit(0)); full Phase 8 drops the exit callback so splash reveals chat instead.
The --no-splash CLI flag flows from Phase 9 main.py → constructor

Re-export note

textual_adapter.py and app.py aren't widgets — no widgets/__init__.py changes expected. Import as from batman_code.textual_adapter import ... and from batman_code.app import BatmanApp (the latter only from Phase 9's main.py).

Phase 9 — CLI Entry Point — COMPLETE

Full plan: see tasks/archive/phase9-plan.md (archived on close). This checklist mirrors that doc's per-commit shape with check-offs added per commit.

Batch 12 — `main.py` (~880 LOC) — 6 of 6 landed

feat(batman-cli): extend run_textual_app with persona + no_splash params (09b56eb)
- Prep commit: run_textual_app gains persona: str = "batman" and no_splash: bool = False kwargs, threaded straight into the BatmanApp constructor. Both params were added to BatmanApp in Phase 8 (commit 84098a0) but the wrapper wasn't updated, so main.py couldn't reach them.
- 2 bundled signature/forwarding tests (inspect.signature for defaults + inspect.getsource for the two persona=persona / no_splash=no_splash forwards).
feat(batman-cli): port main.py with import remaps + persona flag + no_splash (cf543d7)
- 800-LOC replacement of the Phase 0/1 stub.
- Mechanical port: all deepagents_cli.* imports (10 top-level + ~7 inline lazy imports) → batman_code.*; create_cli_agent → create_batman_agent with persona= kwarg; description → "bat-code — Batman-themed AI Coding Assistant"; version → f"bat-code {__version__}"; 5 ~/.deepagents/ error paths → ~/.bat-code/; deepagents -r / deepagents threads list hints → bat-code ...; apply_stdin_pipe docstring examples → | bat-code; check_cli_dependencies messages → bat-code + cd libs/batman-cli && uv sync guidance.
- CLI surface change: -a/--agent (unconstrained, default "agent") replaced by -p/--persona (choices=PERSONA_NAMES, default=DEFAULT_PERSONA="batman"). Persona value feeds both create_batman_agent(persona=...) (prompt overlay) AND assistant_id (memory namespace) — one flag, one mental model. threads list --agent filter → threads list --persona; reset --agent stays verbatim (subcommand-scoped target identifier).
- New --no-splash flag threaded through run_textual_cli_async → run_textual_app → BatmanApp. run_textual_cli_async gains persona + no_splash kwargs.
- No narrative Gotham theming yet — chrome strings like "Resuming thread" / "Application error" / "Interrupted" stay verbatim. Deferred to commit 4 (theming pass) to keep the port diff scoped to structural + identity fixes.
- Post-port: bat-code --help renders the persona flag with the 5 choices; bat-code -p invalid is rejected by argparse; zero deepagents_cli references remain in libs/batman-cli/ source.
test(batman-cli): cover main.py pure-logic helpers (a1889f7)
- 33 unit tests in tests/test_main.py covering:
  - check_cli_dependencies — all-present / single-missing (with "bat-code" wording assertion + upstream "deepagents CLI" guard) / all-missing enumeration.
  - parse_args argparse surface — defaults; -p accepts all 5 canonicals + rejects unknown; dropped -a/--agent no longer parses; --no-splash toggles; -r bare vs. -r <id>; sandbox choice constraint; subparsers (help / list / reset / skills / threads); reset --agent required; threads list --persona filter rename + ls alias + delete positional. Version output regression guard: prints "bat-code" not "deepagents-cli".
  - apply_stdin_pipe — six branches (sys.stdin=None passthrough, TTY passthrough, empty piped passthrough, no-flag → sets non_interactive_message, existing -n prepend, existing -m prepend), plus docstring example regression guard. Uses a small _StdinStub (StringIO + settable isatty) and patches os.open to raise so TTY restoration doesn't touch the real terminal.
  - run_textual_cli_async — signature exposes persona + no_splash with correct defaults, calls create_batman_agent (regression guard against create_cli_agent), forwards persona to BOTH the agent factory AND run_textual_app, forwards no_splash to run_textual_app.
  - Identity regression guards — no from deepagents_cli imports, description says "bat-code" not "Deep Agents", cli_main paths point at ~/.bat-code/, hint strings use bat-code -r / bat-code threads list.
- Suite: 278 passed (33 new + 245 prior).
feat(batman-cli): theme main.py narrative strings with Gotham voice (259bd22)
- Chrome-only Gotham voice pass on run_textual_cli_async + cli_main. Applies Phase 8's locked vocabulary (Cases / Batcomputer / Villain detected / Batcave):
  - Case vocabulary (threads): "Resuming thread: " → "Reopening case: "; "Starting with thread: " → "Opening new case: "; "No previous thread for '...'" → "No prior case for '...'"; "No previous threads, starting new." → "No prior cases on file. Opening a new one."; "Thread 'X' not found." → "Case 'X' not on file."; "Did you mean?" → "Similar case files?"; "available threads" → "available case files"; "resume the most recent thread" → "reopen the most recent case"; "View this thread in LangSmith" → "View this case in LangSmith"; "Resume this thread with:" → "Reopen this case with:".
  - Batcomputer vocabulary (models) — aligns to app.py's /model wording: "Default model {cleared|set to|:}." → "Default Batcomputer {cleared|set to|:}."; "No default model set." → "No default Batcomputer set."; "Could not clear/save default model." → "Could not clear/save default Batcomputer.".
  - Villain / Batcave (errors / exit): "\nApplication error: " → "\nVillain detected: " (mirrors app.py runtime error prefix themed in commit b307c67); Ctrl+C "[yellow]Interrupted[/yellow]" → "[yellow]Left the Batcave.[/yellow]" (mirrors StatusBar's "Ctrl+C to leave the Batcave" hint themed in Phase 8).
- Kept functional (NOT themed): argparse help= strings (they describe operational behavior users see with -h), subcommand names, sandbox choices, [bold red]Error:[/bold red] Rich markup prefix convention, "❌ Missing required CLI dependencies!" (startup diagnostic), "❌ Failed to create agent:" / "❌ Sandbox creation failed" (operational startup failures), all logger.debug/warning messages (internal diagnostics).
test(batman-cli): cover main.py theming regression guards (a40ba9e)
- 10 unit tests appended to tests/test_main.py using inspect.getsource(...) pattern (same as Batches 10 + 11 theming). Covers all 10 themed surfaces above; for each: assert Gotham wording present + upstream wording gone. One test (test_cli_main_resume_hints_use_case_vocabulary) splits its assertion across two adjacent string literals because the source wraps "reopen the most " / "recent case." on separate lines (implicit string concat).
- Suite: 288 passed (10 new + 278 prior). Zero deepagents_cli references remain in libs/batman-cli/ source.
docs: mark Phase 9 COMPLETE (this commit)
- Bumps this checklist (Phase 9 header → COMPLETE, Batch 12 header → 6 of 6, commit 6 checked off).
- Bumps tasks/phase9-plan.md status banner ("5 of 6 commits landed" → COMPLETE) with the final commit range and total tally.
- Updates MEMORY.md: Current Status → [x] Phase 9: COMPLETE; consolidates the two Phase 9 session summaries (commits 1-3 and 4-5) into a single Phase 9 COMPLETE block; rewrites NEXT SESSION pointer to Phase 7 (/batsignal widget — the last widget still deferred per tasks/deferred.md).

Phase 9 tally: 6 commits (09b56eb..<this>), 45 unit tests added (2 + 33 + 10), 288 tests passing across the suite, zero deepagents_cli references in source (only remaining deepagents.* refs are SDK imports from deepagents.backends import ..., which are first-party deepagents package imports).

Phase 10 — End-to-End Verification — IN PROGRESS (final phase)

Full plan: see tasks/phase10-plan.md. Interactive terminal smoke of the assembled bat-code app. Nothing else blocks this — all 9 prior phases are shipped and 334 tests pass on main. Batch 14 kicks off with this commit (plan doc + this header bump); realistic total is 2–5 commits (plan doc + 0–3 fixes + closeout), depending on what live smoke surfaces.

Batch 14 — verification pass

docs: kick off Phase 10 with plan doc + todo checklist (this commit)
- New tasks/phase10-plan.md — scope, batch shape, per-checklist procedure, verification recipe, success criteria.
- This section flipped from "NEXT" to "IN PROGRESS" with the plan-doc pointer above.
[~] Any fix(...) commits surfaced during live smoke (0–3, variable)
- Scoped, with regression tests bundled if <30 LOC.
- Opportunistic approval.py Esc-binding fix if in the way.
- fix(batman-cli): surface 4 missing CLI flags in show_help() (f878e70) — --help smoke caught --no-splash, --model-params, -q/--quiet, --no-stream registered in argparse but absent from ui.show_help(). Fix + parametrized source-inspection guard in tests/test_ui.py. Suite: 334 passed (18 new + 316 prior).
docs: mark Phase 10 COMPLETE — project shipped
- Marks every checkbox below with observed behavior noted.
- Flips plan-doc status banner to COMPLETE; git mv to tasks/archive/; updates archive/README.md.
- Flips libs/batman-cli/README.md status footer to shipped.
- Memory topic files: all phases COMPLETE.

Notes

Port, don't copy blindly: Read each source file, understand it, then adapt. Don't carry over bugs or dead code.
Persona injection: System prompt = system_prompt.md contents + \n\n + prompts/{persona}.md contents. Keep them composable.
Joker safety: Always show a warning when joker persona is active. Never silently enable auto-approve.
Bat-signal layer: Must use Textual's layers CSS feature. Chat interaction must not be blocked.
Splash screen: Use Screen not Widget for the splash — it needs to occupy full terminal.
Local deepagents: All imports from deepagents SDK use from deepagents import ... — the editable install handles resolution.
No modifications to libs/cli or libs/deepagents unless a specific SDK limitation is hit and documented.
