Fixes two corruption patterns that break API keys during updates:
1. Concatenated KEY=VALUE pairs on a single line due to missing newlines
(e.g. ANTHROPIC_API_KEY=sk-...OPENAI_BASE_URL=https://...). Uses a
known-keys set to safely detect and split concatenated entries without
false-splitting values that contain uppercase text.
2. Stale KEY=*** placeholder entries left by incomplete setup runs that
never get updated and shadow real credentials.
Changes:
- Add _sanitize_env_lines() that splits concatenated known keys and drops
*** placeholders
- Add sanitize_env_file() public API for explicit repair
- Call sanitization in save_env_value() on every read (self-healing)
- Call sanitize_env_file() at the start of migrate_config() so existing
corrupted files are repaired on update
- 12 new tests covering splits, placeholders, edge cases, and integration
Seed ~/.hermes/SOUL.md when missing, load SOUL only from HERMES_HOME, and inject raw SOUL content without wrapper text. If the file exists but is empty, nothing is added to the system prompt.
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)
