Demo-Slap Highlight Skill

Generate MP4 highlights and fragmovies from CS2 demos.

This skill is designed for OpenClaw environments where background jobs, local helper scripts, and chat-aware delivery are available. It uses Python 3 scripts and the requests package for HTTP API access.

Expected runtime inputs:

• Required: DEMOSLAP_API_KEY
• Optional: LEETIFY_API_KEY
• Optional deployment helper: DEMO_SLAP_WATCHDOG_JOB_ID

Scripts

Run bundled scripts relative to the skill root, usually from scripts/.

Demo-Slap

Leetify

Match source selection

• Prefer Leetify for recent match discovery when LEETIFY_API_KEY is available.
• If LEETIFY_API_KEY is not configured but DEMOSLAP_API_KEY is available, use Demo-Slap match history from /public-api/matches.
• Swagger: https://api-doc.demo-slap.net/
• Treat Demo-Slap match history as the fallback discovery path for listing matches and selecting an existing analyzed match or replay context before analyze/render.

Runtime files

Use these files as optional local runtime state during execution:

• data/state.json
• data/highlights.json
• data/history.log
• data/steam_ids.json
• data/config.json

These files are runtime helpers for local operation and are not required to understand or inspect the skill package itself.

state.json tracks the current operation:

{
  "status": "idle|analyzing|rendering|done|error",
  "job_id": "...",
  "render_job_id": "...",
  "chat_id": "telegram:182314856",
  "clip_urls": {"highlight_id": "https://..."},
  "progress": "polling 3/30",
  "last_completed_op": "analyze|render",
  "notification": {
    "sent": false,
    "sent_at": null,
    "last_attempt_at": null,
    "error": null
  },
  "updated_at": "ISO timestamp"
}

Workflow

1. Find the match

Preferred path when LEETIFY_API_KEY is available:

python3 scripts/leetify/leetify_matches.py \x3CUSERNAME> [--limit 10]

Fallback path when LEETIFY_API_KEY is missing but DEMOSLAP_API_KEY is available:

python3 scripts/demo_slap_matches.py [\x3CUSERNAME>] [--limit 10]

• uses Demo-Slap /public-api/matches
• use the Demo-Slap swagger docs at https://api-doc.demo-slap.net/ if schema details are needed
• if \x3CUSERNAME> is provided and mapped, filter matches to that player's Steam ID when possible
• after the user picks a match, run:

python3 scripts/demo_slap_match_pick.py [\x3CUSERNAME>] --match-index \x3CN>

• treat the returned jobId as the primary handle for downstream Demo-Slap operations

2. Resolve replay URL

Preferred path when using Leetify:

python3 scripts/leetify/leetify_resolve.py \x3CUSERNAME> --match-index \x3CN>

When using Demo-Slap fallback:

python3 scripts/demo_slap_match_pick.py [\x3CUSERNAME>] --match-index \x3CN>

• use the returned jobId as the selected match identifier
• if demoUrl is present, you may still use analyze-by-URL
• if demoUrl is absent, skip URL resolution and continue by API endpoints that accept the existing analyze jobId
• use GET /public-api/analyze/{jobId}/status and GET /public-api/analyze/{jobId}/data to inspect existing highlights
• if the user wants clips and highlights already exist, render directly from that jobId

3. Analyze in background

python3 -u scripts/demo_slap_analyze.py --url '\x3CREPLAY_URL>' --username \x3CUSERNAME> --chat-id \x3CCHAT_ID>

Run with exec(background: true) and keep the returned process/session id.

Optional deployment-specific watchdog pattern for OpenClaw environments:

• Use a watchdog only when background analyze/render work benefits from periodic delivery checks.
• Reuse an existing deployment watchdog when available instead of assuming a new persistent scheduler entry is always needed.
• If a deployment chooses to create or enable a watchdog through the built-in cron tool, keep it scoped to the active run and disable it again after terminal delivery.
• A 2 minute interval is a reasonable default.
• Use scripts/demo_slap_watchdog.sh status|tail|job only as a local helper for inspecting runtime state, logs, or deployment-specific job references.
• Treat data/state.json and data/highlights.json as the source of truth during runtime.

Agent workflow:

1. Choose the match source:
   • Leetify if LEETIFY_API_KEY exists
   • Demo-Slap /public-api/matches if LEETIFY_API_KEY is missing and DEMOSLAP_API_KEY exists
2. If using Leetify, resolve the replay URL and run analyze
3. If using Demo-Slap fallback, pick a match and inspect the returned jobId
4. If the selected Demo-Slap match already has analyze data, continue by jobId instead of forcing analyze-by-URL
5. Use or enable a deployment watchdog only when long-running analyze/render work benefits from it
6. Launch analyze or render and save the returned process/session id when applicable
7. Let the watchdog deliver the result when a deployment uses one
8. Disable the watchdog again after terminal delivery

4. Render in background

# Single highlight
python3 -u scripts/demo_slap_render.py \x3CJOB_ID> \x3CHIGHLIGHT_ID> --chat-id \x3CCHAT_ID>

# Fragmovie
python3 -u scripts/demo_slap_render.py \x3CJOB_ID> \x3CID1> \x3CID2> ... --fragmovie --chat-id \x3CCHAT_ID>

Run with exec(background: true) and keep the returned process/session id.

Optional deployment-specific watchdog pattern for OpenClaw environments:

• Use a watchdog only when background analyze/render work benefits from periodic delivery checks.
• Reuse an existing deployment watchdog when available instead of assuming a new persistent scheduler entry is always needed.
• If a deployment chooses to create or enable a watchdog through the built-in cron tool, keep it scoped to the active run and disable it again after terminal delivery.
• A 2 minute interval is a reasonable default.
• Use scripts/demo_slap_watchdog.sh status|tail|job only as a local helper for inspecting runtime state, logs, or deployment-specific job references.
• Treat data/state.json and data/highlights.json as the source of truth during runtime.

Agent workflow:

1. Enable or reuse a deployment watchdog only when needed for the active run
2. Launch render and save the returned process/session id
3. Poll process output for the Estimated finish: line and tell the user the ETA if present
4. Let the watchdog deliver the result when one is in use
5. Disable the watchdog again after terminal delivery

Critical: set \x3CCHAT_ID> from inbound metadata of the originating request. Treat hardcoded chat identifiers as local examples only, not as a reusable default.

5. Check status

Read data/state.json.

Setup

Map username to Steam ID

python3 scripts/leetify/leetify_save_id.py \x3CUSERNAME> \x3CSTEAM_64_ID>

Configure API keys

Prefer environment variables:

• DEMOSLAP_API_KEY - required
• LEETIFY_API_KEY - optional, only for Leetify-backed match discovery
• DEMO_SLAP_WATCHDOG_JOB_ID - optional deployment-specific helper for watchdog inspection scripts

Source selection rules:

• If LEETIFY_API_KEY exists, use Leetify for match discovery.
• If LEETIFY_API_KEY is absent but DEMOSLAP_API_KEY exists, use Demo-Slap /public-api/matches for match discovery.
• DEMOSLAP_API_KEY is always required for analyze/render.

Optional local fallback for controlled self-hosted setups: put them in data/config.json.
