fix: sync session_id after mid-run context compression

Critical bug: when the agent's context compressor fires during a tool
loop (_compress_context), it creates a new session_id and writes the
compressed messages there. But the gateway's session_entry still pointed
to the old session_id. On the next message, load_transcript() loaded
the stale pre-compression transcript, causing:

- Context bloat returning every turn
- Repeated compression cycles
- Loss of carefully compressed context

Fix: after run_conversation() returns, check if the agent's session_id
changed (compression split) and sync it back to the session store entry.
Also pass the effective session_id in the result dict so _handle_message
writes transcript entries to the correct session.

This affects ALL gateway adapters, not just webhook.

 The filtering happens at prompt build time in `agent/prompt_builder.py`. The `build_skills_system_prompt()` function receives the set of available tools and toolsets from the agent and uses `_skill_should_show()` to evaluate each skill's conditions.
 
+### Skill setup metadata
+
+Skills can declare secure setup-on-load metadata via the `required_environment_variables` frontmatter field. Missing values do not hide the skill from discovery; they trigger a CLI-only secure prompt when the skill is actually loaded.
+
+```yaml
+required_environment_variables:
+  - name: TENOR_API_KEY
+    prompt: Tenor API key
+    help: Get a key from https://developers.google.com/tenor
+    required_for: full functionality
+```
+
+The user may skip setup and keep loading the skill. Hermes only exposes metadata (`stored_as`, `skipped`, `validated`) to the model — never the secret value.
+
+Legacy `prerequisites.env_vars` remains supported and is normalized into the new representation.
+
+```yaml
+prerequisites:
+  env_vars: [TENOR_API_KEY]       # Legacy alias for required_environment_variables
+  commands: [curl, jq]            # Advisory CLI checks
+```
+
+Gateway and messaging sessions never collect secrets in-band; they instruct the user to run `hermes setup` or update `~/.hermes/.env` locally.
+
+**When to declare required environment variables:**
+- The skill uses an API key or token that should be collected securely at load time
+- The skill can still be useful if the user skips setup, but may degrade gracefully
+
+**When to declare command prerequisites:**
+- The skill relies on a CLI tool that may not be installed (e.g., `himalaya`, `openhue`, `ddgs`)
+- Treat command checks as guidance, not discovery-time hiding
+
+See `skills/gifs/gif-search/` and `skills/email/himalaya/` for examples.
+
 ### Skill guidelines
 
 - **No external dependencies unless absolutely necessary.** Prefer stdlib Python, curl, and existing Hermes tools (`web_extract`, `terminal`, `read_file`).

+## Setup
+
+Set your Tenor API key in your environment (add to `~/.hermes/.env`):
+
+```bash
+TENOR_API_KEY=your_key_here
+```
+
+Get a free API key at https://developers.google.com/tenor/guides/quickstart — the Google Cloud Console Tenor API key is free and has generous rate limits.
+
 ## Prerequisites
 
-- `curl` and `jq` (both standard on Linux)

+## Secure Setup on Load
+
+Use `required_environment_variables` when a skill needs an API key or token. Missing values do **not** hide the skill from discovery. Instead, Hermes prompts for them securely when the skill is loaded in the local CLI.
+
+```yaml
+required_environment_variables:
+  - name: TENOR_API_KEY
+    prompt: Tenor API key
+    help: Get a key from https://developers.google.com/tenor
+    required_for: full functionality
+```
+
+The user can skip setup and keep loading the skill. Hermes never exposes the raw secret value to the model. Gateway and messaging sessions show local setup guidance instead of collecting secrets in-band.
+
+Legacy `prerequisites.env_vars` remains supported as a backward-compatible alias.
