When a skill declares required_environment_variables in its YAML
frontmatter, missing env vars trigger a secure TUI prompt (identical
to the sudo password widget) when the skill is loaded. Secrets flow
directly to ~/.hermes/.env, never entering LLM context.
Key changes:
- New required_environment_variables frontmatter field for skills
- Secure TUI widget (masked input, 120s timeout)
- Gateway safety: messaging platforms show local setup guidance
- Legacy prerequisites.env_vars normalized into new format
- Remote backend handling: conservative setup_needed=True
- Env var name validation, file permissions hardened to 0o600
- Redact patterns extended for secret-related JSON fields
- 12 existing skills updated with prerequisites declarations
- ~48 new tests covering skip, timeout, gateway, remote backends
- Dynamic panel widget sizing (fixes hardcoded width from original PR)

- Tag duckduckgo-search skill with fallback_for_toolsets: [web] so it
auto-hides when Firecrawl is available and auto-shows when it isn't
- Add 'Conditional Activation' section to CONTRIBUTING.md with full
spec, semantics, and examples for all 4 frontmatter fields
- Add 'Conditional Activation (Fallback Skills)' section to the user-
facing skills docs with field reference table and practical example
- Update SKILL.md format examples in both docs to show the new fields
Follow-up to PR #785 (conditional skill activation feature).
Add Python DDGS library examples for all 4 search types (text, news,
images, videos) with return field documentation, quick reference table,
and validated gotchas. Reorganize to put Python API primary, CLI secondary.
Soften Firecrawl-fallback framing. All examples validated on ddgs==9.11.2.
Follow-up to PR #267 merge:
- Fix CLI syntax: -k is keywords, -m is max results (was reversed)
- Add clear trigger condition: use only when web_search tool unavailable
- Remove misleading curl fallback (DuckDuckGo Instant Answer API is not
a web search endpoint)
- Fix package name: ddgs (renamed from duckduckgo-search)
- Add workflow section for search → web_extract pipeline
- Add pitfalls and limitations sections
- Fix author attribution to actual contributor
- Rewrite shell script as simple ddgs wrapper with availability check
