Week of Jan 1–8: Multi-Agent Architecture and Knowledge Tiers
119 sessions across the trading platform's repos. Top concepts: Solana (12), DBT (11), ClickHouse (9), SQL (9), Rust (9).
Activity
119 Claude Code sessions this week across the trading platform’s repos.
| Project | Sessions |
|---|---|
| Trading terminal | 104 |
| Internal tooling | 9 |
| Other repos | 6 |
Heavy day pattern: Jan 1 (26), Jan 2 (30), Jan 7 (24), Jan 8 (36). The cluster around Jan 7-8 was ADR work and a deep dive on knowledge architecture.

-
ADR-001: Multi-Agent Coordination via File-Based Handover — Finalized the approach for how multiple Claude Code sessions coordinate across repos. Evaluated: parent-directory CLAUDE.md, git worktrees, shared MCP server. Chose a hybrid of CLAUDE.md + HANDOVER.md + PROGRESS.md for simplicity without operational overhead.
-
Knowledge Architecture design — Defined hot/warm/cold storage tiers for the team’s internal knowledge system. Hot: CLAUDE.md and HANDOVER.md (always in context). Warm: session logs and ADRs (queryable). Cold: archived decisions and historical digests.
-
Fine-tuning glossary — Started a glossary to standardize terminology for team onboarding across the trading platform.

Solana and DBT flagged for deliberate study — high mention count without full fluency yet.
Learning Questions Worth Revisiting
From this week’s sessions:
- “Why is state being held like such, any way to be more explicit?” — Investigating ColdFusion-style state patterns in the Rust block processor. The issue was two different types sharing the same key prefix in RocksDB.
- “How does the discriminator be used here?” — Program discriminators in Anchor (Solana’s framework). A discriminator is an 8-byte prefix on account data that identifies which account type/instruction is being handled.
- “Do CF holder state and CF token account state happen in sequence?” — Tracing the migration ordering in the state machine. Yes, they’re sequential — the token account state depends on holder state being current.
Notes
Discovered the frontend repo uses a non-main development branch. Changed my branch assumptions going forward.
Session logging system is now writing daily. The pattern of high-volume days around deep architectural work is clear already.
