Example
User: "Summarize this article: https://evolink.ai/blog/deepseek-v4-release-window-prep"
Output:
## TL;DR
DeepSeek V4 has been rumored since January 2026 but still hasn't officially
launched as of March. Multiple predicted windows have passed. The model is
expected to focus on coding with 90% HumanEval scores (unverified).
## Key Takeaways
- Reuters reported in Jan that DeepSeek plans a coding-focused model for Feb 2026
- DeepSeek silently expanded context from 128K to 1M tokens in Feb — likely V4 infra testing
- Unverified benchmarks claim 90% HumanEval, 80%+ SWE-bench Verified
- "V4 Lite" appeared on DeepSeek's site in March but was never officially confirmed
- Multiple launch windows (mid-Feb, Lunar New Year, early March) all passed without release
## Action Items
- Do not migrate production workloads until official announcement
- Monitor DeepSeek's official channels for confirmed specs
- Prepare API integration — EvoLink will support V4 on day oneConfiguration

Security
Credentials & Network
EVOLINK_API_KEY is required to call the Evolink API for summarization. Extracted content is sent to api.evolink.ai and discarded after the response is returned. No data is stored. Review Evolink's privacy policy before sending sensitive content.
Required binaries: curl, python3, realpath, file, stat. Optional: yt-dlp, ffmpeg, whisper, pdftotext, markitdown.
File Access Controls
File paths are resolved via realpath -e (requires file to exist, resolves all symlinks). Symlink inputs are explicitly rejected.
The resolved path must fall within SUMMARIZE_SAFE_DIR (default: $HOME/.openclaw/workspace). A trailing-slash comparison prevents prefix-bypass attacks.
Sensitive files are blacklisted by name: .env*, *.key, *.pem, *.p12, *.pfx, id_rsa*, authorized_keys, config.json, .bash_history, .ssh, shadow, passwd.
Tiered size limits: 5MB text / 50MB PDF / 1GB media. MIME validation via file --mime-type.
Temporary Files
Transcripts and subtitles created in /tmp during processing are cleaned up after extraction. PID-based filenames prevent collisions.
Persistence & Privilege
This skill does not modify other skills or system settings. No elevated or persistent privileges are requested.
