sn-image-base.md

from "OpenSenseNova/SenseNova-Skills"

Base-layer skill for the SenseNova-Skills project, providing low-level APIs for image generation, recognition (VLM), and text optimization (LLM). This skill does not preprocess inputs; it only calls backend services and returns results. This skill is not user-facing and is intended for upper-layer skills only.

sn-ppt-creative.md

from "OpenSenseNova/SenseNova-Skills"

Creative-mode PPT pipeline. One full-page 16:9 PNG per slide. LLM / VLM calls go through sn-ppt-standard/lib/model_client.py (shared thin client). Text-to-image (the actual png rendering) goes through sn-image-base/scripts/sn_agent_runner.py. Expects task_pack.json + info_pack.json already written by sn-ppt-entry.

sn-ppt-doctor.md

from "OpenSenseNova/SenseNova-Skills"

Environment diagnostic for the PPT family. Validates sn-image-base, API keys, Node runtime, and optional deps; interactively writes .env for required vars. Runs before sn-ppt-entry; does not modify sn-image-* skills.

sn-update.md

from "OpenSenseNova/SenseNova-Skills"

Update SenseNova Skills (the sn-* bundle) inside an OpenClaw or hermes-agent install. ALWAYS use this skill when the user says any of: "update SenseNova skills", "update SN skills", "更新 sensenova skills", "更新 sn skills", "刷新 sn-*", "升级 sn-* skills", or names a specific sn-* skill to update (e.g. "更新 sn-ppt-standard", "refresh sn-image-base"). Default scope is the whole sn-* bundle; if the user names specific skills, update ONLY those.

sn-ppt-standard

This skill is self-contained — no dependency on sn-image-base for LLM/VLM (T2I still goes through sn-image-base). Every call through $SKILL_DIR/scripts/run_stage.py. Every subcommand is deterministic: one input set → one output artifact → one-line JSON status.

Preconditions

<deck_dir>/task_pack.json exists and ppt_mode == "standard"
<deck_dir>/info_pack.json exists

Any missing → stop and tell user to enter via /skill sn-ppt-entry.

🚫 Hard rules (the main agent MUST NOT)

Do NOT write Python scripts that loop over pages or slots in a single exec. Use the batch subcommands, or per-item execs in the agent's own loop of tool_calls.
Do NOT fake image generation. If gen-image fails, don't write a placeholder PNG — the HTML stage will redesign around the missing slot.
Do NOT construct LLM prompts yourself. run_stage.py is the only place that builds payloads.
Do NOT add timing / logging / retry layers. The skill is intentionally thin.
Do NOT go silent between execs. Echo a one-line Chinese progress message after each exec before issuing the next.
Do NOT use python-pptx or any alternative PPTX builder when export is skipped or fails. The HTML pages are complete as-is — there is no fallback renderer. An absent PPTX is an acceptable ending state.

Pipeline

R="python3 $SKILL_DIR/scripts/run_stage.py"
D="<deck_dir>"

$R preflight     --deck-dir $D              # validate + stage assets
$R style         --deck-dir $D              # -> style_spec.json
$R outline       --deck-dir $D              # -> outline.json
$R asset-plan    --deck-dir $D              # -> asset_plan.json

# Per-item forms — one progress line per item:
$R gen-image     --deck-dir $D --page N --slot SLOT_ID
$R page-html     --deck-dir $D --page N

# Batch (concurrent) equivalents — default 4 workers. Each prints one summary
# JSON to stdout plus per-item status lines to stderr.
$R batch-gen-image  --deck-dir $D [--concurrency 4]
$R batch-page-html  --deck-dir $D [--concurrency 4]

$R export        --deck-dir $D              # -> <deck_id>.pptx

batch-gen-image serializes writes to asset_plan.json under a process-local lock so concurrent workers don't clobber each other.

How `page-html` works (two LLM calls per page)

Rewrite — prompts/page_html_rewrite.md converts the structured outline + style_spec + inherited content into a natural-language user prompt (content, layout, palette, inherited material).
Generate — prompts/page_html.md is a hard-contract system prompt (document shell, image path format, ECharts rules, single-layer background, <span> wrapping rule, language lock). Receives the rewritten query as the user message and returns the final <!DOCTYPE html>...</html>.

This split keeps converter-facing mechanical contracts (chart container id = chart_N, {renderer:'svg'}, __pptxChartsReady counter, allowed chart types, etc.) in the generator's system prompt — not buried in the natural-language query where they'd get smoothed out.

Output on each exec

One JSON line to stdout:

{"status": "ok", "page_no": 3, "path": "images/page_003_hero.png"}

or on failure (exit code 1):

{"status": "failed", "error": "<reason>", "page_no": 3}

For gen-image failures: don't retry, don't substitute — the HTML stage will redesign around it.

Progress echo — MANDATORY

Stage	Example
After preflight	`已进入 sn-ppt-standard，共 N 页`
After style	`[1] style_spec.json ✓ 主色 #2D5BFF`
After outline	`[2] outline.json ✓ 10 页`
After asset-plan	`[3] asset_plan.json ✓ N 槽位`
Per gen-image	`[图 5/14] page_003/hero ✓` or `... ✗ 服务端 502`
After all gen-image	`图片生成阶段完成：成功 12，失败 2`
Per page-html	`[页 3/10] HTML ✓`
After export	`PPTX ✓ (10/10 页)` or `PPTX 失败: ...`

Silence for more than ~30 seconds = a bug.

Resume semantics

The script is stateless — re-run a subcommand and it'll overwrite its output artifact. Quick ls <deck_dir> decides what's left:

style_spec.json exists → skip style
outline.json exists → skip outline
asset_plan.json exists → skip asset-plan (but any slot whose local_path is missing or status != "ok" still needs gen-image)
pages/page_NNN.html exists → skip page-html for that page
<deck_id>.pptx exists → skip export

scripts/resume_scan.py emits a JSON manifest summarizing all this.

Env

Configured via .env at the repo root (or <repo>/skills/.env). model_client.py auto-loads both. Required:

SN_API_KEY for shared text/vision/image-generation auth, or per-kind overrides SN_CHAT_API_KEY / SN_TEXT_API_KEY / SN_VISION_API_KEY / SN_IMAGE_GEN_API_KEY
SN_BASE_URL, SN_IMAGE_GEN_MODEL

Optional SN_CHAT_BASE_URL / SN_TEXT_BASE_URL / SN_VISION_BASE_URL, SN_CHAT_MODEL / SN_TEXT_MODEL / SN_VISION_MODEL, and SN_CHAT_TIMEOUT / SN_TEXT_TIMEOUT / SN_VISION_TIMEOUT override defaults.

Run python $SKILL_DIR/lib/model_client.py health to verify env before running the pipeline.

Export PPTX gate

scripts/export_pptx/html_to_pptx.mjs is invoked with --force — skips built-in motif / real-photo gates (this skill doesn't use the motif protocol). PPTX still produces even if some slots are missing images.

If the headless browser (Playwright/Chromium) is unavailable, the export returns status: "skipped" with reason "headless_browser_unavailable". The PPTX file is absent — this is an expected degraded ending state. The HTML pages are the final deliverable.

🚫 DO NOT fall back to python-pptx, libreoffice, or any other converter. DO NOT attempt to install Chromium system dependencies manually. Simply report the skip and finish.

Does NOT

Does not call sn-image-base for LLM/VLM (only for T2I).
Does not retry failed model calls.
Does not write progress to disk.
Does not do per-page visual review or rewriting (removed in this iteration).
