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.
It Worked on My Machine, but Nobody Could Trigger It — Four Assumptions I Stripped Out of a Cowork Plugin
I bundled four working automation skills into a plugin and shared it. Only one of them ever fired. Here is how I measured skill trigger rate, and the four assumptions — vocabulary, paths, connections, and naming — I had to strip out before it was portable.
The Morning My Table Ended in "… 2,847 more rows" — Separating Render Caps from Token Cost in Tool Output
Claude Code 2.1.209 caps markdown tables at 200 rows plus a remainder count. Only the rendering is capped — the model still receives every row. Here is how to measure the gap and redesign tool output around aggregates.
Answering auto mode's confirmation prompts in headless runs — a deny-by-default permission-prompt-tool
auto mode's confirmation step is a friend when you're at the keyboard, but in an unattended midnight run it becomes the reason a job sits waiting until morning. Here is how I catch those prompts with permission-prompt-tool, decide deny-by-default, and log every ruling — with working code.
One Day My Push Had an Extra Destination — Guarding Against /commit-push-pr Pushing to Remotes Beyond origin
The July 14 update made /commit-push-pr push to configured push remotes in addition to origin. Convenient, but if you keep a mirror or backup as a second remote, unintended pushes quietly multiply. Here is how to inventory which remotes you can push to, block anything off the allowlist with a pre-push hook, and keep unattended runs safe — with working code.
When You Give an API Key an Expiration Date, Expiry Becomes a Plan Instead of an Accident
The Console now lets you set expiration dates on API keys. Here is how to fold planned expiry into unattended operations — with overlapping dual keys and a local expiry ledger — so your nightly jobs never go dark.
When a Connector Starts Slowing Down at Night: A Health-Aware Circuit Breaker for Solo Automation
Seeing connector errors and latency is only half the job — the other half is deciding when to route around them. This is my implementation of a circuit breaker that opens on error rate and p95, with runnable Python and notes on wiring it into nightly jobs.
Carrying Decisions Across Compaction with PreCompact and SessionEnd Hooks
Auto-compaction does not delete your conversation. It deletes the reasons behind it. Here is a working PreCompact / SessionEnd / SessionStart hook pipeline that rescues decisions to disk and hands them to the next session, with real code and measurements.
A connector failed for two nights and I never noticed — instrumenting my solo setup after observability went to public beta
The week connector observability hit public beta, I realized my one-person operation had no view into errors or latency. Here is how I wrapped my MCP connector calls in a thin meter and started reviewing it weekly.
I Could Detect Failures — Then the Alerts Grew So Loud I Stopped Noticing
The moment I could detect silent job failures, my phone started buzzing too often to be useful. Here is how I collapsed alerts by action rather than event, added hysteresis and quiet hours, and built a three-step escalation so only the pages worth waking me survive.
Rolling Out Trusted Devices for a Small Team: Enrollment, Preflight, and Rotation
How to introduce Team/Enterprise Trusted Devices for a 2-5 person team: device enrollment, an unattended-run preflight gate, and closing the gaps that appear during device rotation and offboarding.
Fable 5 Is Back Worldwide and Sonnet 5 Is the Default — Where Each of the Three Models Belongs in a Solo Automation Stack
With Fable 5 redeployed worldwide and Sonnet 5 now the default, solo automation suddenly has three capable top-tier models to reach for. Instead of ranking them, this piece assigns each a role and captures that in a policy object with a fallback ladder and run-level logging.
