* Add `agent-browser skills` command
Adds a `skills` CLI command that serves bundled skill content at runtime,
always matching the installed CLI version. This solves the problem of
agents relying on stale cached SKILL.md files after CLI upgrades.
The `npx skills add vercel-labs/agent-browser` flow now installs a single
thin discovery skill with trigger words for all use cases (browser
automation, dogfooding, Electron apps, Slack, etc.) that directs agents
to `agent-browser skills get <name>` for current instructions. The other
five skills (dogfood, electron, slack, vercel-sandbox, agentcore) are
marked `metadata.internal: true` so they are not installed by default but
remain accessible via the CLI command.
Subcommands:
skills [list] List available skills
skills get <name> [--full] Get skill content (with optional references)
skills get --all Get all skill content
skills path [name] Print skill directory path
* Fix skills command robustness: UTF-8 safety, flag handling, path output
- Make truncate_description UTF-8-safe using char_indices() instead of
byte-indexed slicing that panics on multi-byte codepoints
- Pass get_all as a bool parameter to run_get instead of embedding
--all as a sentinel string in the names list
- Canonicalize skills_dir path so `skills path` output is clean
- Warn on unrecognized flags in `skills get` instead of silently
ignoring them
* Add evals framework and strengthen SKILL.md for better agent compliance
Strengthen SKILL.md loading instructions to require `skills get` before
running commands, and trim skill descriptions to prevent agents from
guessing at command syntax. Add TypeScript/Bun eval framework that tests
skill-loading, skill-selection, and command-usage via Claude CLI with
Vercel AI Gateway. Evals pass 20/20 (100%), up from 85% baseline.
* Fix formatting in skills.rs
* Add Codex provider to evals framework
Add multi-provider support with a shared Provider interface. Codex
provider spawns `codex exec --json`, parses JSONL output, and writes
~/.codex/config.toml for AI Gateway routing. Use `--provider codex`
to run evals with Codex (default model: openai/o3). First run scores
19/20 (95%) with 100% on skill-loading and skill-selection.
* Use scoped temp dir for Codex config instead of overwriting ~/.codex
* fix: add ref for cursor-interactive content roles
* fix: format
* feat: always include cursor-interactive elements in snapshot, -C is deprecated
* feat: process StaticText aggregation and deduplication
* update test
* clean up
* fix: escape text of elements in snapshot
* fix: redundant slicing
* fix: cargo fmt
* feat: deduplicate redundant StaticText
