JUNIE: The Customer Proxy in Our Development Workflow
Why we are putting a customer-proxy agent inside pull requests, and why passing tests is no longer enough proof.

/handoff and /pickup: An Ephemeral Handover Doc Instead of Yet Another Doc To Rot
We borrowed /handoff from Matt Pocock, added /pickup, and now we have a paired Claude Code skill that gives us a deliberate, throwaway context bridge across /clear — instead of the usual cargo-cult HANDOFF.md that nobody updates and nobody trusts.

On Intent Coherence
The dominant failure mode in modern systems isn't error — it's drift. A discipline for keeping high-volume, AI-assisted systems honest.

I Shipped a 7MB Hero. The Cleanup, and the Fix You Should Actually Do
Astro 5 optimises images — but only the ones in src/. Files in public/ are served byte-for-byte. Here's how I patched a 7MB AI-generated hero with cwebp in thirty seconds, and the schema change that means I'll never have to do it again.

jq — the data plucker for @injectionator
When an n8r probe spits out a hundred kilobytes of JSON, you don't need to read it — you need to pluck the bits that matter. A small reminder about a small tool, and how your favourite LLM can drive it for you.

The Difference Between Claude Code /effort medium and /effort high
A side-by-side comparison of Claude Code effort settings on the same prompts. The results were qualitatively different enough to make me reconsider using /effort medium, or at least do more testing as I go.

Agents Are Just Distributed Systems With Delusions of Grandeur
I've been building agentic AI and winging significant portions of it. So I sat down and worked through the reading list I should have done six months ago. Here's what I found — and the structured guide I compiled from it.

Your AI Agent Is Mr Magoo: Why Knowledge Search Changes Everything
AI coding agents are brilliant but short-sighted — they can't see what they haven't been shown. Here's how a searchable knowledge layer transforms AI-assisted development — and the results we've seen.

Eleven Instruments, One Command
Coherence v1.6 ships a unified /coherence command with 11 subcommands organised into four questions about your project's health.

Entropy at Velocity: Keeping Your Codebase Coherent When AI Writes Most of the Code
AI-assisted development generates code faster than humans can track. Here's the four-layer system that keeps it coherent — and how we help teams implement it.

Your AI Can't Spell Your Company Name
How we built automated guardrails that stop Claude from writing 'View Yonder' — and taught a marketing team to use them without touching a terminal.

Drift vs Consistency: Two Ways Your Codebase Lies to You
One checks whether your code matches your docs. The other checks whether your content matches your standards. Here's why you need both.

The M in MVP Has Changed: Riding Jevons Paradox from Minimal to Maximal Viable Product
AI coding tools don't make software smaller—they make it bigger. The marginal cost of ambition collapsed. What's left is you, deciding how hard to press.
