Convergence dashboard

Each card below tracks one agentic-coding pattern across the three primary tools. A pattern is converged when all three tools have shipped it. The timeline shows the sequence of adoptions — who first, who followed, who has not yet.

3 patterns currently tracked. The registry grows as new patterns converge or as historical patterns get backfilled; expect the count to drift upward, not the existing entries.

Safety 1 pattern

Plan mode

Safety
Converged 2026-03-05 3 of 3 tools

A read-only phase where the agent reads, analyzes, and proposes a plan without writing files. Mitigates premature action on unclear intent.

Scale 1 pattern

Subagent delegation

Scale
Not yet converged 1 of 3 tools

Spawning a child agent with its own context and tools to handle a bounded sub-task, returning a summary to the parent.

Context 1 pattern

Top-level briefing document

Context
Converged 2026-03-05 3 of 3 tools

A conventional filename at the repo root (CLAUDE.md / GEMINI.md / AGENTS.md) where authors encode project context for stateless agents.

How to read this

The registry lives at changelog/patterns.yaml. Each tool's adoption timeline lives at changelog/tools/<tool>.yaml. The dashboard joins them at build time — no code edits needed to add new patterns or new adoption events.

A pattern with convergence_date: null is either a partial convergence (1 or 2 of 3 tools) or an open design space where the right shape is still being argued. Either way, it is information worth surfacing, not hiding.

Coverage is intentionally sparse in the early book — the registry grows organically through quarterly audit cycles. Pattern nominations are welcome via Issues.
