feat(video_gen): unified video_generate tool with pluggable provider backends (#25126)
* feat(video_gen): unified video_generate tool with pluggable provider backends

One core video_generate tool, every backend a plugin. Mirrors the
image_gen + memory_provider + context_engine architecture: ABC, registry,
plugin-context registration hook, and per-plugin model catalogs surfaced
through hermes tools.

Surface (one schema, every backend):
- operation: generate / edit / extend
- modalities: text-to-video (prompt only), image-to-video (prompt +
  image_url), video edit (prompt + video_url), video extend (video_url)
- reference_image_urls, duration, aspect_ratio, resolution,
  negative_prompt, audio, seed, model override
- Providers ignore unknown kwargs and declare what they support via
  VideoGenProvider.capabilities() — backend-specific quirks stay in the
  backend, the agent learns one tool

Backends shipped:
- plugins/video_gen/xai/  — Grok-Imagine, full generate/edit/extend +
  image-to-video + reference images (salvaged from PR #10600 by
  @Jaaneek, reshaped into the plugin interface)
- plugins/video_gen/fal/  — Veo 3.1 (t2v + i2v), Kling O3 i2v,
  Pixverse v6 i2v with model-aware payload building that drops keys a
  model doesn't declare

Wiring:
- agent/video_gen_provider.py — VideoGenProvider ABC, normalize_operation,
  success_response / error_response, save_b64_video / save_bytes_video,
  $HERMES_HOME/cache/videos/
- agent/video_gen_registry.py — thread-safe register/get/list +
  get_active_provider() reading video_gen.provider from config.yaml
- hermes_cli/plugins.py — PluginContext.register_video_gen_provider()
- hermes_cli/tools_config.py — Video Generation category in
  hermes tools, plugin-only providers list, model picker per plugin,
  config write to video_gen.{provider,model}
- toolsets.py — new video_gen toolset
- tests: 31 new tests covering ABC, registry, tool dispatch, both plugins
- docs: developer-guide/video-gen-provider-plugin.md (parallel to the
  image-gen guide), sidebar + toolsets-reference + plugin guides updated

Supersedes: #25035 (FAL), #17972 (FAL), #14543 (xAI), #13847 (HappyHorse),
#10458 (provider categories), #10786 (xAI media+search bundle), #2984
(FAL duplicate), #19086 (Google Veo standalone — easy port to plugin
interface).

* feat(video_gen): dynamic schema reflects active backend's capabilities

Address the 'capability variance' question — instead of one tool with a
static schema that lies about what every backend supports, the
video_generate tool now rebuilds its description at get_definitions()
time based on the configured video_gen.provider and video_gen.model.

The agent sees backend-specific guidance up-front:
- 'fal-ai/veo3.1/image-to-video': 'image-to-video only — image_url is
  REQUIRED; text-only prompts will be rejected'
- 'fal-ai/veo3.1' (t2v): no image_url restriction shown
- xAI grok-imagine-video: 'operations: generate, edit, extend; up to 7
  reference_image_urls'
- Backends without edit/extend: 'not supported on this backend — surface
  that they need to switch backends via hermes tools'

This is the same pattern PR #22694 used for delegate_task self-capping —
documented in the dynamic-tool-schemas skill. Cache invalidation is
free: get_tool_definitions() already memoizes on config.yaml mtime, so a
mid-session backend swap rebuilds the schema automatically.

Tested:
- Empirical FAL OpenAPI schema check confirms image-to-video models
  require image_url (FAL returns HTTP 422 otherwise) — client-side
  rejection in FALVideoGenProvider.generate() now prevents the wasted
  round-trip
- Live E2E: fal-ai/veo3.1/image-to-video + prompt-only → clean
  missing_image_url error; fal-ai/veo3.1 + prompt-only → dispatches
- 6 new tests cover the builder (no config / image-only / full-surface /
  text-only / unknown provider / registry wiring), all passing
- 37/37 in the slice, 134/134 in the broader regression set

* test(video_gen/xai): full surface integration tests + cleaner schema

Verified end-to-end that the xAI plugin handles every documented mode
from PR #10600's surface: text-to-video, image-to-video,
reference-images-to-video, video edit, video extend (with and without
prompt). All five modes route to the correct xAI endpoint
(/videos/generations, /videos/edits, /videos/extensions) with the right
payload shape (image / reference_images / video keys), and all five
client-side rejections fire before the network: edit-without-prompt,
extend-without-video_url, image+refs conflict, >7 references, and
duration/aspect_ratio clamping.

15 new integration tests grouped into four classes (endpoint routing,
modalities, validation, clamping). httpx is stubbed via a small fake
AsyncClient that records POSTs so the tests assert the actual payload
the plugin would send to xAI — not just the success/error envelope.

Also cleaned up a description redundancy: when a model's operations
match the backend's overall set, we no longer print the duplicate
'operations supported by this model' line. xAI's description now reads:

    Active backend: xAI . model: grok-imagine-video
    - operations supported by this backend: edit, extend, generate
    - modalities supported by this backend: image, reference_images, text
    - aspect_ratio choices: 16:9, 1:1, 2:3, 3:2, 3:4, 4:3, 9:16
    - resolution choices: 480p, 720p
    - duration range: 1-15s
    - reference_image_urls: up to 7 images

* feat(video_gen): collapse surface to t2v + i2v, family-based auto-routing

Two design changes per Teknium:

1) Drop edit/extend from the tool surface entirely. Only text-to-video
and image-to-video remain. The agent sees a clean tool with two
modalities; backend-specific quirks like xAI's edit/extend endpoints
stay out of the unified schema.

2) FAL: pick a model FAMILY once, the plugin routes between the
family's text-to-video and image-to-video endpoints based on whether
image_url was passed. Users no longer pick 'fal-ai/veo3.1' AND
'fal-ai/veo3.1/image-to-video' as separate options — they pick
'veo3.1', and the plugin handles the rest.

Catalog rewritten as families:

    veo3.1            fal-ai/veo3.1                                /  fal-ai/veo3.1/image-to-video
    pixverse-v6       fal-ai/pixverse/v6/text-to-video             /  fal-ai/pixverse/v6/image-to-video
    kling-o3-standard fal-ai/kling-video/o3/standard/text-to-video /  fal-ai/kling-video/o3/standard/image-to-video

xAI uses a single endpoint (/videos/generations) for both modes,
routed by the presence of the 'image' field in the payload — no
edit/extend exposure.

Schema changes:
- VIDEO_GENERATE_SCHEMA: drop operation, drop video_url. Final params:
  prompt (required), image_url, reference_image_urls, duration,
  aspect_ratio, resolution, negative_prompt, audio, seed, model.
- VideoGenProvider ABC: drop normalize_operation, VALID_OPERATIONS,
  DEFAULT_OPERATION. capabilities() drops 'operations' key.
- success_response: add 'modality' field ('text' | 'image') so the
  agent and logs can see which endpoint was actually hit.

Dynamic schema builder simplified — no operations bullet, no
'switch backends if you need edit/extend' guidance. When the active
backend supports both modalities (the common case), description reads:

    Active backend: FAL . model: pixverse-v6
    - supports both text-to-video (omit image_url) and image-to-video
      (pass image_url) - routes automatically
    - aspect_ratio choices: 16:9, 9:16, 1:1
    - resolution choices: 360p, 540p, 720p, 1080p
    - duration range: 1-15s
    - audio: pass audio=true to enable native audio (pricing tier)
    - negative_prompt: supported

Tests: 51 in the video_gen slice, 216 across the broader image+video
sweep, all passing. New FAL routing tests prove pixverse-v6 + no image
hits text-to-video endpoint, pixverse-v6 + image_url hits
image-to-video endpoint, same for veo3.1 and kling-o3-standard.

Docs updated: developer-guide page rewrites the 'model families' pattern
as a first-class section so external plugin authors know the convention.
toolsets-reference and toolsets.py descriptions match the new surface.

* feat(video_gen/fal): expand catalog to 6 families, cheap + premium tiers

Catalog now covers everything Teknium specced from FAL:

  Cheap tier:
    ltx-2.3        fal-ai/ltx-2.3-22b/text-to-video       / image-to-video
    pixverse-v6    fal-ai/pixverse/v6/text-to-video       / image-to-video

  Premium tier:
    veo3.1         fal-ai/veo3.1                          / fal-ai/veo3.1/image-to-video
    seedance-2.0   bytedance/seedance-2.0/text-to-video   / image-to-video
    kling-v3-4k    fal-ai/kling-video/v3/4k/text-to-video / image-to-video
    happy-horse    fal-ai/happy-horse/text-to-video       / image-to-video

DEFAULT_MODEL moved from veo3.1 (premium) to pixverse-v6 (cheap, sane
defaults, both modalities) — better first-run UX for users who haven't
explicitly picked a model.

New family-entry knob: image_param_key. Kling v3 4K's image-to-video
endpoint expects start_image_url instead of image_url; declaring
image_param_key='start_image_url' on the family lets _build_payload
remap correctly. Other families default to plain image_url.

Per-family capability flags reflect each model's docs:
- LTX 2.3 + Happy Horse: minimal payloads (no duration/aspect/resolution
  enum exposed by FAL — let endpoint apply defaults)
- Seedance: 6 aspect ratios incl 21:9, durations 4-15, audio supported,
  negative prompts NOT supported per docs
- Kling v3 4K: 16:9/9:16/1:1, 3-15s, audio + negative
- Veo 3.1: unchanged, 16:9/9:16, 4/6/8s

Tests: +5 covering the new families (full catalog, Kling 4K
start_image_url remap, Seedance routing, LTX payload minimality, Happy
Horse minimality). 56/56 in the slice green.

Note: I did NOT add the FAL-hosted xAI Grok-Imagine variant. Hermes
already has a direct xAI plugin that talks to xAI's own API; routing
the same model through FAL's wrapper would duplicate the surface
without adding capabilities. Users on FAL who want Grok-Imagine should
use the xAI plugin directly; flag if you want both routes available.

* test(video_gen): tool-surface routing matrix — every model x modality

End-to-end matrix test driven through _handle_video_generate() — the
actual function the agent's video_generate tool call lands in. Writes
config.yaml, invokes the registered handler with a raw args dict, then
asserts the outbound HTTP/SDK call hit the right endpoint with the right
payload shape.

Parametrized over FAL_FAMILIES.keys() so the matrix auto-discovers new
families as they're added (add a family to FAL_FAMILIES and you get
both modalities tested for free).

Coverage:
- All 6 FAL families x {text-only, text+image} = 12 cases
- xAI x {text-only, text+image} = 2 cases
- tool-level model= arg overrides config = 2 cases

For each case, verifies:
- result['success'] is True
- result['modality'] matches input shape ('text' if no image_url, 'image' otherwise)
- outbound endpoint URL matches the family's text_endpoint or image_endpoint
- text-only payloads carry no image-shaped keys
- text+image payloads carry the family's image key (image_url for most,
  start_image_url for kling-v3-4k, wrapped 'image' object for xAI)

All 16 cases passing. Confirms the tool surface routes every
(provider, model, modality) combination correctly with zero leakage.

* feat(video_gen): keep video_gen out of first-run setup, surface in status

Two changes:

1. video_gen joins _DEFAULT_OFF_TOOLSETS, so it is NOT pre-selected in
   the first-run toolset checklist. Video gen is niche, paid, and slow —
   most users don't want it nagging them during initial setup. Anyone
   who wants it opts in via 'hermes tools' -> Video Generation, which
   already routes to the provider+model picker.

2. The 'hermes setup' status panel learns about video_gen — but only
   shows the row when a plugin reports available. Users without
   FAL_KEY/XAI_API_KEY see nothing about video gen; users with one of
   those keys see 'Video Generation (FAL) ✓' as confirmation it's wired.

Verified live:
- Fresh install (no creds): zero video_gen mentions in wizard.
- With FAL_KEY: status row appears with active backend name.
- 160/160 in the setup + tools_config + video_gen test slice.

Rationale: image_gen is on by default because it's a featured creative
tool used in casual chat (telegrams, etc). Video gen is heavier — long
wait, paid per-second pricing. Default-off matches user intent better.

4 Toolsets Reference Reference for Hermes core, composite, platform, and dynamic toolsets

Toolsets Reference

Toolsets are named bundles of tools that control what the agent can do. They're the primary mechanism for configuring tool availability per platform, per session, or per task.

How Toolsets Work

Every tool belongs to exactly one toolset. When you enable a toolset, all tools in that bundle become available to the agent. Toolsets come in three kinds:

  • Core — A single logical group of related tools (e.g., file bundles read_file, write_file, patch, search_files)
  • Composite — Combines multiple core toolsets for a common scenario (e.g., debugging bundles file, terminal, and web tools)
  • Platform — A complete tool configuration for a specific deployment context (e.g., hermes-cli is the default for interactive CLI sessions)

Configuring Toolsets

Per-session (CLI)

hermes chat --toolsets web,file,terminal
hermes chat --toolsets debugging        # composite — expands to file + terminal + web
hermes chat --toolsets all              # everything

Per-platform (config.yaml)

toolsets:
  - hermes-cli          # default for CLI
  # - hermes-telegram   # override for Telegram gateway

Interactive management

hermes tools                            # curses UI to enable/disable per platform

Or in-session:

/tools list
/tools disable browser
/tools enable rl

Core Toolsets

Toolset Tools Purpose
browser browser_back, browser_cdp, browser_click, browser_console, browser_dialog, browser_get_images, browser_navigate, browser_press, browser_scroll, browser_snapshot, browser_type, browser_vision, web_search Core browser automation. Includes web_search as a fallback for quick lookups. browser_cdp and browser_dialog are gated at runtime — registered only when a CDP endpoint is reachable at session start (via /browser connect, browser.cdp_url config, Browserbase, or Camofox). browser_dialog works together with the pending_dialogs and frame_tree fields that browser_snapshot adds when a CDP supervisor is attached.
clarify clarify Ask the user a question when the agent needs clarification.
code_execution execute_code Run Python scripts that call Hermes tools programmatically.
cronjob cronjob Schedule and manage recurring tasks.
debugging composite (file + terminal + web) Debug bundle — file, process/terminal, web extract/search.
delegation delegate_task Spawn isolated subagent instances for parallel work.
discord discord Core Discord text/embed/DM actions (gateway-only). Active on the hermes-discord toolset.
discord_admin discord_admin Discord moderation (bans, role changes, channel management). Active on the hermes-discord toolset; requires the bot to hold the relevant Discord permissions.
feishu_doc feishu_doc_read Read Feishu/Lark document content. Used by the Feishu document-comment intelligent-reply handler.
feishu_drive feishu_drive_add_comment, feishu_drive_list_comments, feishu_drive_list_comment_replies, feishu_drive_reply_comment Feishu/Lark drive comment operations. Scoped to the comment agent; not exposed on hermes-cli or other messaging toolsets.
file patch, read_file, search_files, write_file File reading, writing, searching, and editing.
homeassistant ha_call_service, ha_get_state, ha_list_entities, ha_list_services Smart home control via Home Assistant. Only available when HASS_TOKEN is set.
computer_use computer_use Background macOS desktop control via cua-driver — does not steal cursor/focus. Works with any tool-capable model. macOS only; requires cua-driver on $PATH.
image_gen image_generate Text-to-image generation via FAL.ai (with opt-in OpenAI / xAI backends).
video_gen video_generate Text-to-video and image-to-video via plugin-registered backends (xAI Grok-Imagine, FAL.ai Veo 3.1 / Pixverse v6 / Kling O3). Pass image_url to animate an image; omit it for text-to-video.
kanban kanban_block, kanban_comment, kanban_complete, kanban_create, kanban_heartbeat, kanban_link, kanban_show Multi-agent coordination tools — only registered when the agent is spawned by the kanban dispatcher (HERMES_KANBAN_TASK env set). Lets workers mark tasks done with structured handoffs, block for human input, heartbeat during long ops, comment on threads, and (for orchestrators) fan out into child tasks.
memory memory Persistent cross-session memory management.
messaging send_message Send messages to other platforms (Telegram, Discord, etc.) from within a session.
moa mixture_of_agents Multi-model consensus via Mixture of Agents.
rl rl_check_status, rl_edit_config, rl_get_current_config, rl_get_results, rl_list_environments, rl_list_runs, rl_select_environment, rl_start_training, rl_stop_training, rl_test_inference RL training environment management (Atropos).
safe image_generate, vision_analyze, web_extract, web_search (via includes) Read-only research + media generation. No file writes, no terminal, no code execution.
search web_search Web search only (without extract).
session_search session_search Search past conversation sessions.
skills skill_manage, skill_view, skills_list Skill CRUD and browsing.
spotify spotify_albums, spotify_devices, spotify_library, spotify_playback, spotify_playlists, spotify_queue, spotify_search Native Spotify control (playback, queue, search, playlists, albums, library). Registered by the bundled spotify plugin.
terminal process, terminal Shell command execution and background process management.
todo todo Task list management within a session.
tts text_to_speech Text-to-speech audio generation.
vision vision_analyze Image analysis via vision-capable models.
video video_analyze Video analysis and understanding tools (opt-in, not in the default toolset — add explicitly via --toolsets).
web web_extract, web_search Web search and page content extraction.
yuanbao yb_query_group_info, yb_query_group_members, yb_search_sticker, yb_send_dm, yb_send_sticker Yuanbao DM/group actions and sticker search. Registered only on hermes-yuanbao.

Platform Toolsets

Platform toolsets define the complete tool configuration for a deployment target. Most messaging platforms use the same set as hermes-cli:

Toolset Differences from hermes-cli
hermes-cli Full toolset — the default for interactive CLI sessions. Includes file, terminal, web, browser, memory, skills, vision, image_gen, todo, tts, delegation, code_execution, cronjob, session_search, clarify, and safe (read-only) bundles plus the standard messaging tools.
hermes-acp Drops clarify, cronjob, image_generate, send_message, text_to_speech, and all four Home Assistant tools. Focused on coding tasks in IDE context.
hermes-api-server Drops clarify, send_message, and text_to_speech. Keeps everything else — suitable for programmatic access where user interaction isn't possible.
hermes-cron Same as hermes-cli.
hermes-telegram Same as hermes-cli.
hermes-discord Adds discord and discord_admin on top of hermes-cli.
hermes-slack Same as hermes-cli.
hermes-whatsapp Same as hermes-cli.
hermes-signal Same as hermes-cli.
hermes-matrix Same as hermes-cli.
hermes-mattermost Same as hermes-cli.
hermes-email Same as hermes-cli.
hermes-sms Same as hermes-cli.
hermes-bluebubbles Same as hermes-cli.
hermes-dingtalk Same as hermes-cli.
hermes-feishu Adds the five feishu_doc_* / feishu_drive_* tools (only used by the document-comment handler, not the regular chat adapter).
hermes-qqbot Same as hermes-cli.
hermes-wecom Same as hermes-cli.
hermes-wecom-callback Same as hermes-cli.
hermes-weixin Same as hermes-cli.
hermes-yuanbao Adds the five yb_* tools (DM/group/sticker) on top of hermes-cli.
hermes-homeassistant Same as hermes-cli (the Home Assistant tools are already present by default and activate when HASS_TOKEN is set).
hermes-webhook Same as hermes-cli.
hermes-gateway Internal gateway orchestrator toolset — union of every hermes-<platform> toolset; used when the gateway needs to accept any message source.

Dynamic Toolsets

MCP server toolsets

Each configured MCP server generates a mcp-<server> toolset at runtime. For example, if you configure a github MCP server, a mcp-github toolset is created containing all tools that server exposes.

# config.yaml
mcp_servers:
  github:
    command: npx
    args: ["-y", "@modelcontextprotocol/server-github"]

This creates a mcp-github toolset you can reference in --toolsets or platform configs.

Plugin toolsets

Plugins can register their own toolsets via ctx.register_tool() during plugin initialization. These appear alongside built-in toolsets and can be enabled/disabled the same way.

Custom toolsets

Define custom toolsets in config.yaml to create project-specific bundles:

toolsets:
  - hermes-cli
custom_toolsets:
  data-science:
    - file
    - terminal
    - code_execution
    - web
    - vision

Wildcards

  • all or * — expands to every registered toolset (built-in + dynamic + plugin)

Relationship to hermes tools

The hermes tools command provides a curses-based UI for toggling individual tools on or off per platform. This operates at the tool level (finer than toolsets) and persists to config.yaml. Disabled tools are filtered out even if their toolset is enabled.

See also: Tools Reference for the complete list of individual tools and their parameters.
