Branch with /fork, Delegate with /subtask — Two Commands That Traded Jobs

In Claude Code 2.1.212, /fork now clones your conversation into a background session, and in-session subagents moved to /subtask. Here is how I decide between them, and the budgets worth setting before you start branching freely.

My Nightly Subagents Ran, and I Couldn't Retrace Them — Trimming the Logs That --forward-subagent-text Unleashed

Subagent text and thinking can now flow into stream-json output, and unattended log volume climbs sharply with it. Here are measured numbers, a three-tier retention filter that keeps only what postmortems need, and a correlation ID design that survives missing fields.

Don't Accept an Agent's Numbers and Citations As-Is — A Verification Gate Built on a Dedicated Auditor Subagent

A design that verifies every number and citation in an agent-generated summary using a separate subagent before accepting it — with working TypeScript for deterministic recomputation and fail-closed source matching.

Running Subagents in Parallel Without One Failure Sinking the Whole Run

A fan-out / fan-in design for running several subagents in parallel, covering token budgeting, a result contract, and partial-failure handling. Includes an implementation where one branch can fail without stopping the rest, plus measured numbers.

A SubagentStop Hook That Grades Subagent Output and Sends It Back to Be Redone

When a Claude Code subagent occasionally returns rule-breaking work, a SubagentStop hook can grade it automatically and ask for a redo. Here is a working setup with code and field notes.

Context Budgets for Nested Subagents: Designing Contracts So 5-Level Delegation Doesn't Lose Quality

Once subagents could nest, deeper delegation made summaries thinner and reruns more frequent. Here is how I rebuilt quality by adding four contracts between layers: token budgets, a handoff schema, failure isolation, and an independent grader.

How Deep Should Nested Subagents Go? Rethinking My Delegation Tree After Claude Code's 5-Level Limit

Claude Code subagents can now spawn their own subagents, up to five levels deep. I rebuilt my automation around nesting and settled on three levels — here is why.

Authoring Dynamic Workflows: Building Reusable Research Pipelines with phase / agent / pipeline

A hands-on guide to writing your own Claude Code Dynamic Workflows: the phase / agent / pipeline / parallel primitives, locking outputs with JSON Schema, porting the adversarial-verification pattern, and designing for token cost.

Running Claude Code's Dynamic Workflows: What I Learned About Orchestrating Subagents

A hands-on walk through Claude Code's Dynamic Workflows (v2.1.154): running /deep-research, enabling the feature, watching progress with /workflows, and saving a workflow for reuse, from an indie developer's angle.

Skill, Subagents, and Rules in Claude Code: A One-Hour Implementation Loop That Fits a Solo Operator

Misaki Ito at SonicGarden wrote about wiring Claude Code's Skill, Subagents, and Rules to close a week's worth of low-priority work in one meeting. Here is how I adapted that pattern as a solo developer running a 50M-download app business.

Pruning Custom Subagents in Claude Code: After Six Months, Five Became Two

I built five custom subagents in Claude Code, ran them across six sites for six months, and ended up keeping only two. Here are the notes I took along the way — what worked, what didn't, and how I learned to write subagent descriptions that actually get called.
