Skills vs Subagents vs MCP: Which Claude Code Extension to Reach For (and When to Compose All Three)
Three ways to extend Claude Code, and founders keep picking the wrong one — building an MCP server when a skill would do, or writing a skill for something that needs live data. The rule of thumb is one sentence, and the 2026 answer is usually 'all three, layered.'

Mask a JWT or AWS Key in Claude Code's Sandbox Without Breaking the Tool
Whole-value masking hides a bare token fine — but it corrupts a JWT your code decodes or an AWS key the SDK signs with. Claude Code v2.1.224 adds three structured fields (extract, decode: jwt, awsPairs) that keep the tool working while the agent still never holds the plaintext. Here's the exact config for each.

LangChain Cut a Default Agent Turn's Input Tokens by 65% — and It Wasn't a Smaller Model
Deep Agents v0.7 dropped a default turn from 5,395 to 1,895 input tokens with no quality regression. The savings came from deleting prose that duplicated the tool schemas the model already sees — a tax your own harness is almost certainly still paying.

Claude Code Removed the 200-Subagent Cap. Now Three Other Limits Govern Your Fleet
v2.1.224 (August 7) deleted the hard per-session ceiling that made long orchestrations fail at agent 201.

What OpenCode is, who it's for, how to start in one command, what it costs (as of July 2026), and the honest catch — the terminal coding agent that refuses to lock you to a single model vendor, now at ~7.5M developers.

GitHub Copilot Added Its First Open-Weight Model. The Story Isn't the Price — It's the Exit.
Kimi K2.7 Code landed in Copilot's model picker on July 1. Every other model there is a black box you rent. This is the first one whose weights are on Hugging Face — the first row with a way out.

How to Switch GitHub Copilot to Kimi K2.7 (and What It Actually Saves You)
The first open-weight model in Copilot's picker is also the cheapest tier. Here's how to enable it org-wide, when to route to it versus a frontier model, the real cost math, and the self-host fallback that makes it a floor, not a hope.

vLLM v0.24 Makes Model Runner V2 the Default. The Win Isn't a Faster Kernel — It's Never Waiting on the CPU.
The June 29 release flips vLLM's rebuilt execution core on by default and lands a Rust serving front-end. The throughput comes from deleting the CPU–GPU sync, not from a hotter matmul.

How to Build a Coding Agent (The Loop Is the Easy Part)
A working coding agent is a few hundred lines and four tools — a weekend. What separates a toy from Claude Code is everything that isn't the loop: the edit contract, what you keep out of context, and whether it runs the tests.

Claude Code Dynamic Workflows vs Subagents: When to Move the Plan Into Code
Subagents let Claude delegate a few tasks per turn. Dynamic workflows fan out hundreds. The line between them isn't how many agents you need — it's whether the plan is stable enough to freeze into a script.

Running Open Models in Claude Code: What the Anthropic-Compatible Endpoint Silently Turns Off
GLM-5.2, Kimi, and MiniMax all ship an Anthropic-compatible endpoint, so pointing Claude Code at them is a one-line base-URL swap. The model runs — but 'compatible' is a promise about the wire format, not about the harness features your bill and your speed depend on.

Claude Code Nested Subagents: The Depth Cap Is 5, but Your Token Bill Is the Real Limit
Subagents can now spawn subagents five levels deep. The number that decides whether you should is not the depth — it's how much billed work happens at branches the root never reads.

AGENTS.md vs Agent Skills: What Vercel's Evals Actually Prove
A compressed 8KB index in AGENTS.md scored 100% on Vercel's coding-agent evals; Skills topped out at 79% — because the agent skipped invoking the Skill 56% of the time. The lesson isn't "dumb beats smart."

OpenCode vs Claude Code: You're Comparing a Harness to a Product
OpenCode passed Claude Code on GitHub stars this year, and everyone rushed to benchmark them against each other. But one of them has no benchmark score of its own — and that's the whole point.

Cursor's DuneSlide Flaws: When a Path Check Fails Open, Prompt Injection Becomes RCE
Two zero-click Cursor flaws let a poisoned MCP response overwrite the editor's own sandbox binary. The root cause wasn't a bad command — it was a path validator that failed open.

Claude Code Agent Teams vs Subagents: When Your Workers Need to Talk to Each Other
Claude Code's new experimental Agent Teams let parallel sessions message each other and share a task list. The real question isn't 'do I want parallelism' — subagents already give you that — it's whether your workers need to disagree.

How to Evaluate an AI Coding Agent
Public leaderboards answer 'which model is smartest,' not 'will it fix my bugs' — the only test that predicts your outcome is a private eval built from your own repo.

When "Trust This Folder" Means Remote Code Execution: The Amazon Q Flaw Every Coding Agent Shipped
Amazon Q auto-ran an MCP config out of any repo you opened, with your live AWS keys in the process. It got a CVE. The identical bug in Claude Code, Cursor, Gemini CLI and Copilot got declared working-as-designed — because the trust prompt you inherited from your editor was never a consent to run code.

Does an AGENTS.md File Actually Make Your Coding Agent Better?
The first rigorous benchmark of repository context files is in, and the answer is uncomfortable: the auto-generated ones make agents slightly worse, the hand-written ones barely help, and both raise your bill ~20%.

Google Antigravity vs Cursor vs Claude Code: What 'Agent-First' Actually Moves
Google's Antigravity, Cursor, and Claude Code now all hit ~80% on SWE-bench. So the real difference isn't who writes better code — it's where each one puts the work of checking it.

Fast-Apply Models: How Cursor, Morph, and Relace Write Edits at 4,000+ Tokens/Second
The bottleneck in a coding agent isn't the smart model deciding what to change. It's the dull mechanical work of writing that change to disk correctly — and that's a different model entirely.

Background Coding Agents: Devin vs Codex vs Cursor vs Jules vs Copilot
The async coding agents have all converged on the same shape — a cloud VM that clones your repo, runs the tests, and opens a PR. So the thing you're actually choosing isn't the coder. It's the harness and who reviews the flood.

Git Worktrees Solve the Easy Half of Parallel AI Agents
Worktrees stop your agents from overwriting each other's files. They do nothing about the shared database, the fight over port 3000, or the review queue that becomes your real bottleneck.

Cline vs Roo Code vs Kilo Code: Picking a VS Code Agent in 2026
Three open-source coding agents from one family tree — and the middle child just shut itself down. Its death is the most useful thing in the comparison.

Spec-Driven Development: Spec Kit vs Kiro vs Tessl
Writing a spec before the agent writes code is the loudest idea in AI coding right now. The pitch isn't better code — it's making intent a durable artifact that survives the context window. Three tools bet on that at three different altitudes.

Lovable vs Bolt vs v0 vs Replit: Choosing an AI App Builder in 2026
They all promise an app from a prompt. They differ on the question none of them advertises: when you outgrow the tool, do you get to take the code with you?

How AI Coding Agents Edit Code: Diff vs Whole-File vs Search-Replace
Everyone argues about which model to use. The under-discussed variable is how the agent writes its changes to disk — and that edit format is often the real bottleneck.

CodeRabbit vs Greptile vs Qodo: Choosing an AI Code Review Tool in 2026
Every vendor leads with its bug-catch rate. But code review is the one place in the AI stack where precision beats recall — a reviewer you learn to ignore catches nothing.

Claude Code vs Codex CLI vs Gemini CLI: Picking a Terminal Coding Agent in 2026
Three bets on the same idea — that the command line, not the IDE, is where coding agents live. And as of this month one of the three just changed its name and its terms.

AGENTS.md vs CLAUDE.md: One File to Brief Every Coding Agent
The config-file war for how you talk to a coding agent didn't end with a winner. It ended with a foundation — and that changes which file you should actually write.
