v0.1.5

Changed

• Bumped pinned upstream pi-coding-agent version to 0.79.1 (adds Claude Fable 5 model support, a global defaultProjectTrust setting to configure unresolved-trust behavior, prompt template argument defaults, extension autocomplete trigger characters, and assorted fixes; no changes to the RPC protocol surface or the --approve/--no-approve flags this gem drives).

RubyGems: https://rubygems.org/gems/pi-agent-rb/versions/0.1.5

v0.1.4

Changed

• Bumped pinned upstream pi-coding-agent version to 0.79.0 (cache-hit visibility in footer, richer SDK exports, and assorted fixes; the RPC wire protocol this gem drives is unchanged).
• Behavior change in pi 0.79.0: project-local inputs (.pi/settings.json, project extensions, resources, packages) are now trust-gated. In RPC mode pi does not prompt — without a saved trust decision it silently ignores them. Pass the new approve: true option to keep loading them.

Added

• approve: option on Client.new / PiAgent.session / PiAgent.open: true appends --approve to the pi spawn args (trust the project), false appends --no-approve (explicitly ignore project inputs); the default nil leaves pi's own behavior untouched.

v0.1.3

Changed

• Bumped pinned upstream pi-coding-agent version to 0.77.0 (adds Claude Opus 4.8 metadata, --exclude-tools, and Codex subscription device login; no changes to the RPC protocol surface this gem drives).

Full changelog: v0.1.1...v0.1.2

v0.1.0

First release of pi-agent-rb — a Ruby client for the pi coding agent, driving pi --mode rpc over its JSONL protocol.

Verified against pi 0.75.3.

Added

• Initial project scaffold.
• popen3 transport with JSONL framing and request correlation.
• Pluggable transport.
• Session API with typed event stream.
• Session#run single-shot helper (pi print-mode equivalent).
• Session commands: cycle_model, available_models, messages, last_assistant_text, compact, new_session, switch_session.
• Session#session_stats.
• Session forking and error mapping.
• Image attachments; follow_up uses a dedicated command.
• Extension UI protocol.

Fixed

• Session#set_model now sends provider/modelId (pi rejected the previous single model field).
• Session#set_thinking now sends the set_thinking_level command.

Install

```
gem install pi-agent-rb
```
