PPT Write Skill

Four capabilities: generate, template imitation, edit existing PPT, and local file operations.

Authentication (Required First)

Before using this skill, authentication must be completed. Run the auth script first:

# Authenticate: checks env token / cached token / browser login
python3 <skill-dir>/scripts/skywork_auth.py || exit 1

Token priority:

1. Environment variable SKYBOT_TOKEN → if set, use directly
2. Cached token file ~/.skywork_token → validate via API, if valid, use it
3. No valid token → opens browser for login, polls until complete, saves token

IMPORTANT - Login URL handling: If script output contains a line starting with [LOGIN_URL], you MUST immediately send that URL to the user in a clickable message (e.g. "Please open this link to log in: <url>"). The user may be in an environment where the browser cannot open automatically, so always surface the login URL.

Routing — Identify the user's intent first

Environment check (always run this first)

This skill requires Python 3 (>=3.8). Run the following before any script to locate a valid Python binary and install dependencies.

PYTHON_CMD=""
for cmd in python3 python python3.13 python3.12 python3.11 python3.10 python3.9 python3.8; do
  if command -v "$cmd" &>/dev/null && "$cmd" -c "import sys; exit(0 if sys.version_info >= (3,8) else 1)" 2>/dev/null; then
    PYTHON_CMD="$cmd"
    break
  fi
done

if [ -z "$PYTHON_CMD" ]; then
  echo "ERROR: Python 3.8+ not found."
  echo "Install on macOS: brew install python3  or visit https://www.python.org/downloads/"
  exit 1
fi

echo "Found Python: $PYTHON_CMD ($($PYTHON_CMD --version))"

$PYTHON_CMD -m pip install -q --break-system-packages python-pptx
echo "Dependencies ready."

After this check, replace python with the discovered $PYTHON_CMD (e.g. python3) in all subsequent commands.

Layer 1 — Generate PPT

Steps

0. REQUIRED FIRST STEP — Read workflow_generate.md NOW, before taking any other action. After reading, output exactly: ✅ workflow_generate.md loaded. — then proceed.
1. Environment check — run the check above to get $PYTHON_CMD.
2. Upload reference files (if the user provides local files as content source) — parse the file using tool in script/parse_file.py and pass the result to --files. See the --files note below.
3. Web search (required if no relevant content is already in the conversation) — call web_search tool in script to search the topic and distill results into a reference-file file of ≤ 2000 words.
4. Run the script:

   Important: set exec tool yieldMs to 600000 (10 minutes).

5. Deliver — provide the absolute .pptx path and the download URL.

Layer 2 — Imitate PPT (template-based generation)

Steps

0. REQUIRED FIRST STEP - Read workflow_imitate.md immidiately before any action you do!!!
1. Environment check — run the check above to get $PYTHON_CMD.
2. Locate the template — extract the absolute path of the local .pptx from the user's message; ask the user if it's unclear.
3. Upload the template — upload it and extract TEMPLATE_URL from the output.
4. Upload reference files (if the user provides additional local files as content source) — parse the file using tool in script/parse_file.py and pass the result to --files. See the --files
5. Web search (required if no relevant content is already in the conversation) — call web_search tool in script to search the new topic and distill results into a reference-file file of ≤ 2000 words.
6. Run the script:

   Important: set exec tool yieldMs to 600000 (10 minutes).

7. Deliver — provide the absolute .pptx path, the download URL, and the template filename used.

Layer 4 — Edit PPT (AI-powered modification)

Use this layer when the user wants to modify an existing PPT using natural language. Requires an OSS/CDN URL of the PPTX (from a previous generation or upload).

Steps

0. Detailed workflow - Read workflow_edit.md immediately before any action you do!!!
1. Environment check — run the check above to get $PYTHON_CMD.
2. Get PPTX URL — from the user's message or upload a local file first.
3. Run the script with --pptx-url:

   $PYTHON_CMD scripts/run_ppt_write.py "edit instruction" \
     --language Chinese \
     --pptx-url "https://cdn.example.com/file.pptx" \
     -o /absolute/path/output.pptx
   

   Important: set exec tool yieldMs to 600000 (10 minutes).

4. Deliver — provide download link, local path, and summary of changes.

Layer 3 — Local file operations

# Inspect slide count and titles
$PYTHON_CMD scripts/local_pptx_ops.py info --file my.pptx

# Delete slides (1-based index; supports ranges like 3,5,7-9; omit -o to overwrite in place)
$PYTHON_CMD scripts/local_pptx_ops.py delete --file my.pptx --slides 3,5,7-9 -o trimmed.pptx

# Reorder slides (must list every slide, no omissions)
$PYTHON_CMD scripts/local_pptx_ops.py reorder --file my.pptx --order 2,1,4,3,5

# Extract a subset of slides into a new file
$PYTHON_CMD scripts/local_pptx_ops.py extract --file my.pptx --slides 1-3 -o subset.pptx

# Merge multiple files
$PYTHON_CMD scripts/local_pptx_ops.py merge --files a.pptx b.pptx -o merged.pptx

Read workflow_local.md immidiately before any action you do!!!

Error Handling

• Insufficient benefit: When calling scripts (generate, imitate, or edit), the script or log may show a message like Insufficient benefit. Please upgrade your account at {url}, meaning the user's benefit level does not meet the requirement for this skill.

How to reply when benefit is insufficient

When you detect the above, reply in the user's current language — do not echo the English message. Use this pattern:

• Convey: "Sorry, PPT generation failed. This skill requires upgrading your Skywork membership to use." then a single call-to-action link.
• Format: One short sentence in the user's language + a link like [Upgrade now →](url) or the equivalent in their language .
• URL: Extract the upgrade URL from the log/script output (e.g. the at https://... part).

Dependencies

• Python 3.8+ (required) — python3 / python must be on PATH
• Layer 3 local ops: pip install python-pptx --break-system-packages

(The environment check step installs all required dependencies automatically.)
