segment 1 of 6

Orient on Phase 2 spec, repo docs, and existing code

Done

Agent reads the full Phase 2 scratchpad (D1–D6), CURRENT-TASK.md locked decisions, SOURCES.md adapter contract, CURRENT_STATE.md, the Solo playbook, and memory registry. Then reads all existing Python source files (core.py, cache_strategies.py, cli.py, providers/claude.py, providers/codex.py, __init__.py, providers/__init__.py) and all test files (test_claude_parser.py, test_codex_parser.py, test_cli_contract.py, test_scan_cache.py, test_cache_strategy_resolver.py, conftest.py) to understand the current code layout, dataclasses, cache strategy resolver, scan cache, and test patterns. Confirms repo is clean at start.

outcome

Full understanding of existing codebase, test fixtures, and the Phase 2 deliverables (D1–D6) from scratchpad 888.

next steps

  • Inspect real ~/.pi session files to learn the exact JSONL event schema
  • Create cream/providers/pi.py with PiAccumulator and load_pi_sessions
  • Add pi to PROVIDERS registry and --source choices
  • Add scan cache methods for pi
  • Wire apply_cache_strategy into pi loader
  • Update macOS app for pi source
  • Write tests and fixtures
  • Run existing tests to confirm no regressions
  • Run swift build to confirm macOS app still builds

key decisions

  • Will inspect real ~/.pi session files before writing any code to match actual schema
  • Will follow the spec's D1–D6 deliverables in order
  • Will not re-litigate locked decisions from CURRENT-TASK.md

open questions

  • What is the exact JSONL event schema in ~/.pi/agent/sessions/ files?
  • Does the nested message object contain provider/model/usage fields as expected?
  • Are there session_info events or is title derived differently?
  • What is the deduplication key pattern for Pi assistant messages?

segment 2 of 6

Discover real Pi session file schema

Done

Agent runs Python scripts to inspect ~/.pi/agent/sessions/ files. Discovers 100 JSONL files across multiple project directories. The event types are: session (100), message (12384), model_change (105), thinking_level_change (104), compaction (2). The session event has type/version/id/timestamp/cwd. Messages have a nested 'message' object with role (user/assistant/toolResult/bashExecution). Assistant messages contain provider, model, responseId, responseModel, api, usage (with input/cacheRead/cacheWrite/totalTokens/cost sub-object with input/cacheRead/cacheWrite/output/total). Content is a list of blocks with types text/toolCall/thinking. No session_info events found; title derivation method is still unknown.

outcome

Real Pi schema discovered: nested message object with provider/model/usage/cost fields; no session_info events; 100 session files with 12384 messages across 8 project directories.

next steps

  • Document the discovered schema in the findings scratchpad
  • Create cream/providers/pi.py with PiAccumulator matching the real event shape
  • Determine how to derive session title (possibly from first user message or filename)
  • Create test fixtures from real Pi data
  • Implement load_pi_sessions walking ~/.pi/agent/sessions/--*--/*.jsonl

key decisions

  • Will code to the actual discovered schema (nested message object, no session_info) rather than the planned shape
  • Will use responseId for deduplication as specified, falling back to entry id
  • Will derive provider from assistant message's 'provider' field (cursor/openrouter)
  • Will map usage.input/output/cacheRead/cacheWrite/totalTokens and cost sub-object

open questions

  • How to derive session title when there are no session_info events?
  • What is the exact deduplication pattern — is responseId always present?
  • Should we handle the 'api' field (e.g. 'cursor-sdk') in any special way?
  • Are there any edge cases in the compaction event that affect parsing?

segment 3 of 6

Investigate Pi schema and assess codebase state

Done

The assistant ran a Python script to analyze the Pi session file structure, discovering event types and nested message schemas. It then read multiple source files in the codebase (SessionSummary, ScannerService, views, etc.) to understand the current scanner and Swift app state before planning changes.

outcome

Clear understanding of Pi schema and codebase structure, leading to a detailed plan for Pi support.

segment 4 of 6

Implement Pi source adapter, provider reassignment, and tests

Done

The assistant added a Pi source adapter (cream/providers/pi.py) with nested-message parsing, reassigned Claude/Codex providers to model providers (anthropic/openai), wired Pi into CLI with scan cache v4, added fixtures and tests, and fixed a float representation issue in cost assertions. All parser tests pass.

outcome

Pi source adapter implemented, provider reassignment done, all parser tests pass.

next steps

—

key decisions

  • Pi sessions use provider reassignment to model providers (e.g., anthropic) while source remains 'pi'
  • Claude/Codex now report provider as 'anthropic'/'openai' instead of 'claude'/'codex'
  • Cache inference for Pi uses recency-based provisional active-cache treatment

segment 5 of 6

Update Swift app for source-aware session handling

Done

The assistant updated the Swift code to decode the `source` field, use source-aware stale-row preservation, update ProviderChip to show source label and color by provider, and update diagnostic views to count by source instead of provider. The assistant then fixed a Swift naming collision between a model-row displayName property and the global displayName(forProvider:) function by renaming the property. Rebuilt Swift successfully.

outcome

Swift app now handles source field, with source-aware stale-row preservation and provider-based coloring; naming collision fixed and build passes.

next steps

  • Verify no remaining hardcoded provider/source assumptions
  • Possibly update docs
  • Run full verification

key decisions

  • ProviderChip now shows source label and colors by provider
  • Stale-row preservation uses source counts instead of provider counts
  • Known sources list updated to include 'pi'
  • Renamed model-row displayName to displayNameForProvider to avoid collision with global function

Complete Phase 2 Pi adapter integration and verification

Done

Updated docs (CURRENT_STATE.md, SOURCES.md, CLAUDE.md) to reflect shipped Phase 2 contract including Pi support, scan cache v4, and provider reassignment. Fixed a Swift naming collision between a model-row displayName property and the global displayName(forProvider:) function by renaming the property. Rebuilt Swift successfully. Ran full Python test suite (15 passed) and JSON smoke checks confirming SCAN_CACHE_VERSION=4 and PROVIDERS=('claude','codex','pi'). Added a compatibility fallback for Pi message events with flat role. Wrote Solo findings scratchpad (889) documenting Pi session schema and implementation details. Posted READY comment on todo 524.

outcome

Phase 2 Pi adapter fully integrated with all verification passing; findings documented and review requested.

next steps

—

key decisions

  • Renamed model-row displayName to displayNameForProvider to avoid collision with global function
  • Pi parser supports both nested message.role and flat top-level role for compatibility
  • Scan cache version bumped to 4 for provider reassignment
  • Provider reassignment: Claude -> anthropic, Codex -> openai, Pi -> dynamic from assistant turn
