fix: adversarial review remediation — release v0.1.5 (rounds 2 + 3)#8
Merged
Conversation
Fixes the following issues identified during review remediation:
1. anthropic.rb: Fix escaped string interpolation in ProviderError message
for malformed tool call JSON. Removed backslash-escaping so actual tool
name and parser error appear instead of literal \#{...} text.
2. anthropic.rb: Replace thread-unsafe @_stream_* instance variables with
method-local variables. All streaming state is now scoped to the
method/block via a process_anthropic_stream_event helper.
3. agent/core.rb + all providers: Thread per-agent config to provider
construction. BaseProvider accepts config: kwarg; providers use it
instead of RubyPi.configuration directly.
4. All providers: Detect HTTP error status in on_data streaming callbacks.
Accumulate error response bodies separately so ApiError contains the
full error body even when streaming consumed the response.
5. compaction.rb: Change compaction summary from role: :user to
role: :assistant to prevent consecutive user messages that Anthropic
rejects (strict user/assistant alternation).
6. openai.rb: Raise ProviderError on nil/blank tool_call_id in tool
result messages and assistant tool calls (same fail-fast as Anthropic)
instead of silently sending 'unknown'.
7. gemini.rb: Parse actual finishReason from streaming response instead
of hardcoding 'stop'.
8. README.md: Fix event key references (e[:iteration] -> e[:turn],
event[:iterations] -> event[:result].turns).
9. CHANGELOG.md: Add comprehensive v0.1.4 entry documenting all fixes.
10. base_provider.rb: Remove dead parse_sse_events method (all providers
now use real incremental streaming via on_data).
11. Gemfile + gemspec: Remove arbitrary < 3.4 upper bound on
faraday-net_http.
12. fallback.rb: Stream events directly to consumer on happy path instead
of buffering. Emit :fallback_start event on primary failure so consumer
can clear partial state before fallback streams.
All 444 tests pass.
Addresses defects identified during round-3 review of the round-2 fixes (commit eace165). All 449 specs pass under Ruby 3.4.9. Critical: - Streaming error_body recovery on Gemini and OpenAI: round-2 added the error_body accumulator on all three providers but only Anthropic passed it to handle_error_response. Gemini and OpenAI now also pass override_body so ApiError#response_body carries the real server message on streaming HTTP failures. - Compaction summary role is now context-aware: round-2 changed the role from :user to :assistant to avoid consecutive user messages, but produced consecutive assistants when the first preserved message was already :assistant. The role is now :user when the next preserved is :assistant, and :assistant otherwise. New compaction specs exercise both orderings. - :fallback_start StreamEvent now propagates to agent users via a new :provider_fallback agent event. The agent loop also clears the streamed-content accumulator on fallback so the recorded response reflects only the fallback's output. Major: - StreamEvent#fallback_start? predicate added for symmetry with text_delta?, tool_call_delta?, done?. - Loop#act guards JSON.generate(result.value) against JSON::GeneratorError / TypeError so tools returning Time, Date, or other non-JSON-native objects no longer abort the agent. Falls back to value.to_s. - Tools::Executor.deep_symbolize_keys promoted to a public class method so the loop can apply it once up front. tool_calls_made arguments now match the symbol-keyed shape the tool block receives, instead of leaking the raw string-keyed JSON.parse output through Result#tool_calls_made. Documentation: - Agent::Core#config: kwarg docstring corrected. The kwarg is informational; per-agent provider config must be passed to the model factory: RubyPi::LLM.model(:openai, "gpt-4o", config: cfg). Round-2 CHANGELOG claimed "now flows through to provider construction" — that was untrue and has been corrected. - CHANGELOG: removed two references to nonexistent BufferedStreamProxy class. Restructured 0.1.4 entry to be accurate; added 0.1.5 entry. - CLAUDE.md: "Adding a New LLM Provider" no longer references the deleted parse_sse_events helper; describes the on_data + override_body pattern. Extension example uses event[:result].turns instead of the nonexistent event[:iterations]. Event list updated. - README: documents :fallback_start StreamEvent and the agent-level :provider_fallback event. Tooling: - .gitignore added (.DS_Store, *.gem, vendor/bundle, coverage). - .ruby-version pins to 3.4.9 (matches CI's 3.4 entry). Version bump: 0.1.3 -> 0.1.5 (skipping 0.1.4 — round-2 work was completed but never tagged or published; the 0.1.5 CHANGELOG entry documents both rounds).

Summary
Two rounds of adversarial review remediation, shipping as
v0.1.5. All 449 specs pass under Ruby 3.4.9.Round 2 (commit
eace165)Addressed 12 defects from review v2: Anthropic
\#{...}literal interpolation, thread-unsafe@_stream_*ivars in Anthropic streaming, error-body capture inon_data(Anthropic only — see round 3), compaction-poisoning-system-prompt role change, OpenAItool_call_idfail-fast, Gemini streamingfinishReason, README/CLAUDE.md event-key drift, deadparse_sse_eventsremoval,faraday-net_httpcap removal, Fallback no-longer-buffers happy path,:fallback_startevent introduction.Round 3 (commit
b0f750e)Addressed defects in round 2's fixes:
error_bodywas only wired through on Anthropic — Gemini and OpenAI now also passoverride_body:tohandle_error_response, so streaming HTTP failures actually carry the real server message inApiError#response_body.:assistant. Role is now context-aware (:userif next is:assistant, otherwise:assistant). New specs cover both orderings.:fallback_startwas emitted but silently dropped by the agent loop — the loop now translates it into a new agent-level:provider_fallbackevent and clears the streamed-content accumulator.Agent::Core#config:kwarg was decorative — round-2 CHANGELOG claimed it "flows through to provider construction" but it does not. Docstring and CHANGELOG corrected; per-agent config must be passed to the model factory directly.JSON.generate(result.value)could crash on tools returningTime/Date/custom objects. Now wrapped in a rescue withto_sfallback.tool_calls_madearguments leaked the raw string-keyed JSON.parse output while the tool block received symbol keys. Both now use the symbol-keyed form via the newly-publicTools::Executor.deep_symbolize_keys.StreamEvent#fallback_start?predicate.BufferedStreamProxyclass from CHANGELOG.parse_sse_eventsreference and the wrongevent[:iterations]key.:fallback_startand:provider_fallback.Other
