Changelog
Every real dated milestone found in CLAUDE.md and this repo's session handoffs, newest first.
workers/_template reusable scaffold shipped
A copyable static-docs Worker scaffold with the CSS grid-overflow fix built in from day one.
36-site family resync checklist seeded
Rather than one big manual resync, 36 independently-trackable tasks were seeded on subagenttasks.com.
subagentdocs.com and subagentnews.com launch
Two new primitives: a meta-catalog of this repo's own docs/docs mirrors, and this very changelog.
Full Cloudflare docs + blog mirror landed, with drift tooling
The operator supplied a real, full local mirror of developers.cloudflare.com and www.cloudflare.com. scripts/cf-mirror-sync.py generates a sha256:16 HASHES.json manifest for local drift detection.
subagenttasks.com launches: the Task primitive
Generalized from the real TaskCreate/TaskUpdate/TaskList schema, seeded with this exact session's real 44 tasks.
ANTHROPIC_API_KEY dependency removed from subagentworkers.com
Rebuilt generation on Cloudflare Workers AI, zero external API keys. Fixed an empty-output bug from glm-5.2's enable_thinking default.
subagentskills.com and subagentroles.com launch
The Agent Skill primitive and the Coworker Role primitive launch together. Hit a real mid-session disk-full incident, resolved.
Rubric, Outcome, and Evaluation primitives launch, plus api.com and cli.com
Three linked primitives used to grade the 9 workers shipped earlier the same day against a written-down rubric.
subagentprompts.com launches: the Prompt Engineering primitive
A 14-technique catalog, each citing an exact source doc. Documents this session's real Sonnet-main/Fable-5-advisor pairing.
Identity, Citation, and Cache primitives launch
Three D1-backed primitives built in parallel: agent identity, citations, and real Cloudflare Analytics numbers.
CSS grid-overflow bug fixed across 21 sites
A real user-reported horizontal-overflow bug traced to CSS Grid min-width:auto colliding with long monospace domain tokens; the design-system audit script gained a third hard-gate check.
Claude Fable 5 access restored globally
Verified live: Fable 5 GA'd 2026-06-09, export-control-restricted, restored today across Claude Platform/Claude.ai/Code/Cowork.
subagentdevices.com and subagentdomains.com launch
Dogfooding the design system itself and the whole 20-site portfolio.
plugins/cwc-data launches: the data-coworker plugin
A warehouse-analyst-only Cowork plugin over subagentjobs-dwh, deliberately read-only scoped.
subagentcontracts.com launches: the Contract primitive
The first non-static, durable-state site in the family, grounded in Claude Tag's "the thread is durable" vocabulary.
subagentcode.com launches; engineering-coworker moves to Fable 5
Verified live that Fable 5 was globally restored. engineering-coworker upgraded from Haiku 4.5 to Fable5; the other 8 agents stayed put.
subagentbrands.com launches: the Brand Voice primitive
Adapts the operator's real brand-voice:discover-brand skill to record this family's own observable voice as durable rows.
Ashby/OpenAI ATS support added; workers/etl rebuilt; subagentetl.com launches
Added Ashby support (723 OpenAI jobs ingested), rebuilt workers/etl, fixed a silent dim_board bug, shipped subagentetl.com.
Agent-readiness batch 2: Content-Signal, sitemap.xml, RFC 9727 API catalog
Content-Signal headers on all 36 robots.txt, Agent Skills index, RFC 9727 API Catalog, real sitemap.xml. Fable-5 reviewed, two real issues fixed.
Agent-readiness batch 1: x402, AP2, WebMCP, Web Bot Auth, OAuth discovery
Five real machine-readable protocols shipped on 5 sites. subagentapi.com got a real working MCP Server Card + Streamable-HTTP JSON-RPC /mcp endpoint. Fable-5 caught 10 real spec issues.
Prior session handoff: Rust/Postgres/docs-crawl groundwork
The ancestor handoff both 2026-07-01 sessions chained off of, largely still open.
