`X_BEARER_TOKEN` as fallback; `auto` mode tries twitterapiio first - **Web Search**: Tavily (preferred in auto mode) or Brave; optional, fallback to agent web_search if unavailable - **GitHub**: Auto-generates token from GitHub App if PAT not set; unauthenticated fallback (60 req/hr) - **Reddit**: No API key needed (uses public JSON API) ## Cron / Scheduled Task Integration ### OpenClaw Cron (Recommended) The cron prompt should **NOT** hardcode the pipeline steps. Instead, reference `references/digest-prompt.md` and only pass configuration parameters. This ensures the pipeline logic stays in the skill repo and is consistent across all installations. #### Daily Digest Cron Prompt ``` Read /references/digest-prompt.md and follow the complete workflow to generate a daily digest. Replace placeholders with: - MODE = daily - TIME_WINDOW = past 1-2 days - FRESHNESS = pd - RSS_HOURS = 48 - ITEMS_PER_SECTION = 3-5 - ENRICH = true - BLOG_PICKS_COUNT = 3 - EXTRA_SECTIONS = (none) - SUBJECT = Daily Tech Digest - YYYY-MM-DD - WORKSPACE = - SKILL_DIR = - DISCORD_CHANNEL_ID = - EMAIL = (optional) - LANGUAGE = English - TEMPLATE = discord Follow every step in the prompt template strictly. Do not skip any steps. ``` #### Weekly Digest Cron Prompt ``` Read /references/digest-prompt.md and follow the complete workflow to generate a weekly digest. Replace placeholders with: - MODE = weekly - TIME_WINDOW = past 7 days - FRESHNESS = pw - RSS_HOURS = 168 - ITEMS_PER_SECTION = 10-15 - ENRICH = true - BLOG_PICKS_COUNT = 3-5 - EXTRA_SECTIONS = 📊 Weekly Trend Summary (2-3 sentences summarizing macro trends) - SUBJECT = Weekly Tech Digest - YYYY-MM-DD - WORKSPACE = - SKILL_DIR = - DISCORD_CHANNEL_ID = - EMAIL = (optional) - LANGUAGE = English - TEMPLATE = discord Follow every step in the prompt template strictly. Do not skip any steps. ``` #### Why This Pattern? - **Single source of truth**: Pipeline logic lives in `digest-prompt.md`, not scattered across cron configs - **Portable**: Same skill on different OpenClaw instances, just change paths and channel IDs - **Maintainable**: Update the skill → all cron jobs pick up changes automatically - **Anti-pattern**: Do NOT copy pipeline steps into the cron prompt — it will drift out of sync #### Multi-Channel Delivery Limitation OpenClaw enforces **cross-provider isolation**: a single session can only send messages to one provider (e.g., Discord OR Telegram, not both). If you need to deliver digests to multiple platforms, create **separate cron jobs** for each provider: ``` # Job 1: Discord + Email - DISCORD_CHANNEL_ID = - EMAIL = user@example.com - TEMPLATE = discord # Job 2: Telegram DM - DISCORD_CHANNEL_ID = (none) - EMAIL = (none) - TEMPLATE = telegram ``` Replace `DISCORD_CHANNEL_ID` delivery with the target platform's delivery in the second job's prompt. This is a security feature, not a bug — it prevents accidental cross-context data leakage. ## Security Notes ### Execution Model This skill uses a **prompt template pattern**: the agent reads `digest-prompt.md` and follows its instructions. This is the standard OpenClaw skill execution model — the agent interprets structured instructions from skill-provided files. All instructions are shipped with the skill bundle and can be audited before installation. ### Network Access The Python scripts make outbound requests to: - RSS feed URLs (configured in `tech-news-digest-sources.json`) - Twitter/X API (`api.x.com` or `api.twitterapi.io`) - Brave Search API (`api.search.brave.com`) - Tavily Search API (`api.tavily.com`) - GitHub API (`api.github.com`) - Reddit JSON API (`reddit.com`) No data is sent to any other endpoints. All API keys are read from environment variables declared in the skill metadata. ### Shell Safety Email delivery uses `send-email.py` which constructs proper MIME multipart messages with HTML body + optional PDF attachment. Subject formats are hardcoded (`Daily Tech Digest - YYYY-MM-DD`). PDF generation uses `generate-pdf.py` via `weasyprint`. The prompt template explicitly prohibits interpolating untrusted content (article titles, tweet text, etc.) into shell arguments. Email addresses and subjects must be static placeholder values only. ### File Access Scripts read from `config/` and write to `workspace/archive/`. No files outside the workspace are accessed. ## Support & Troubleshooting ### Common Issues 1. **RSS feeds failing**: Check network connectivity, use `--verbose` for details 2. **Twitter rate limits**: Reduce sources or increase interval 3. **Configuration errors**: Run `validate-config.py` for specific issues 4. **No articles found**: Check time window (`--hours`) and source enablement ### Debug Mode All scripts support `--verbose` flag for detailed logging and troubleshooting. ### Performance Tuning - **Parallel Workers**: Adjust `MAX_WORKERS` in scripts for your system - **Timeout Settings**: Increase `TIMEOUT` for slow networks - **Article Limits**: Adjust `MAX_ARTICLES_PER_FEED` based on needs ## Security Considerations ### Shell Execution The digest prompt instructs agents to run Python scripts via shell commands. All script paths and arguments are skill-defined constants — no user input is interpolated into commands. Two scripts use `subprocess`: - `run-pipeline.py` orchestrates child fetch scripts (all within `scripts/` directory) - `fetch-github.py` has two subprocess calls: 1. `openssl dgst -sha256 -sign` for JWT signing (only if `GH_APP_*` env vars are set — signs a self-constructed JWT payload, no user content involved) 2. `gh auth token` CLI fallback (only if `gh` is installed — reads from gh's own credential store) No user-supplied or fetched content is ever interpolated into subprocess arguments. Email delivery uses `send-email.py` which builds MIME messages programmatically — no shell interpolation. PDF generation uses `generate-pdf.py` via `weasyprint`. Email subjects are static format strings only — never constructed from fetched data. ### Credential & File Access Scripts do **not** directly read `~/.config/`, `~/.ssh/`, or any credential files. All API tokens are read from environment variables declared in the skill metadata. The GitHub auth cascade is: 1. `$GITHUB_TOKEN` env var (you control what to provide) 2. GitHub App token generation (only if you set `GH_APP_ID`, `GH_APP_INSTALL_ID`, and `GH_APP_KEY_FILE` — uses inline JWT signing via `openssl` CLI, no external scripts involved) 3. `gh auth token` CLI (delegates to gh's own secure credential store) 4. Unauthenticated (60 req/hr, safe fallback) If you prefer no automatic credential discovery, simply set `$GITHUB_TOKEN` and the script will use it directly without attempting steps 2-3. ### Dependency Installation This skill does **not** install any packages. `requirements.txt` lists optional dependencies (`feedparser`, `jsonschema`) for reference only. All scripts work with Python 3.8+ standard library. Users should install optional deps in a virtualenv if desired — the skill never runs `pip install`. ### Input Sanitization - URL resolution rejects non-HTTP(S) schemes (javascript:, data:, etc.) - RSS fallback parsing uses simple, non-backtracking regex patterns (no ReDoS risk) - All fetched content is treated as untrusted data for display only ### Network Access Scripts make outbound HTTP requests to configured RSS feeds, Twitter API, GitHub API, Reddit JSON API, Brave Search API, and Tavily Search API. No inbound connections or listeners are created.
