Higher Rate Limits Don't Mean Tighter Schedules — Spend the Headroom on 429 Recovery

When Claude Code's rate limits went up, the instinct was to pack the schedule tighter. Here's why I did the opposite and routed the new headroom into retry budget instead — a pacing note for unattended pipelines.

Productionizing a Claude Design Prototype — Single Source, CI, and OGP Auto-Generation

Turn a Claude Design prototype into something that survives production with Claude Code. The call to keep the generated runtime as your foundation, separating logic with a mixin, a single-source data design around a ledger CSV, and CI auto-updates with real-browser OGP capture — implementation included.

I Watched an Agent Try to Fix a File It Had Already Fixed — Stale Shallow Clones and Refreshing Before You Decide

An unattended agent tried to re-fix a file it had already fixed. The cause was a days-old shallow clone it kept reading. Here is how to detect that staleness numerically and re-clone only before decisions.

Working Between Claude Design and Claude Code — Splitting Diverge and Converge

Rough design in Claude Design, fine detail in Claude Code. Now that the two live close together in the desktop app, here is how to run them as a divide-of-labor between diverging and converging — bridges like Link Local code and Send to included.

When Claude Code Still Writes Stale Code With Context7 Installed — Verifying the Injection Actually Worked

You installed Context7 MCP, yet Claude returns code against a deprecated API. Most of the time the documentation injection silently no-ops. Here are field notes on a hook that detects misses, pinning doc versions, and a harness that checks generated code every time.

Keep MCP Connector Authorization in One Place — A Solo Dev Design That Survives Growing Integrations

When Claude chat, Claude Code, and Cowork each configure the same MCP connector separately, their authorization drifts apart and breaks silently. Here is how to borrow the managed-connector idea of 'provision once, reuse everywhere' as an indie developer.

Handing Claude Design Mockups Straight to Claude Code: Folding the Design-to-Code Loop

The June 17 Claude Design update added codebase-aware generation. Here's how to make your tokens the single source of truth, hand mockups to Claude Code, and collapse the design-to-code round trip — with code you can copy.

Pointing Claude Design at Your Codebase: Closing the Design-to-Implementation Loop Solo

The June 17 update lets Claude Design start from your local codebase, so generated assets reflect your existing components. Here is how I wire code-grounded generation into maintaining four sites' UI alone as an indie developer.

Noticing From the Outside When a Scheduled Job Quietly Did Nothing

exit 0, but zero output. How to catch a silent no-op not from the job's own log but from an external heartbeat ledger and ground truth, written from running several sites on a nightly schedule as an indie developer.

An Article My Gate Rejected Got Published — The Cost of Chaining the Quality Gate and git push in One Call

In an unattended publishing pipeline, an article my quality gate had rejected went live anyway. The cause was chaining the gate and git push into a single shell call. Here is how the exit code gets swallowed, and a two-phase publish-marker design that refuses to push until every gate has demonstrably passed.

The Day a Billing Change Got Reversed at the Last Minute — Designing a Reversible Pipeline So You Don't Rewrite in a Panic

A billing change due to take effect on June 15 was retracted at the eleventh hour. From the position of someone who had literally logged 'effective today' the night before, here is why I didn't have to scramble to rewrite my headless stages, and how to build a pipeline that survives reversals and delays — with working code.
