Plugin Claude Code
The senior dev, unbundled. A cast of opinionated skills that make an AI agent push back on bad ideas, verify before it claims done, attack its own code, and finish like a senior engineer.
Skill Claude CodeCodex
Adversarial self-review for code that touches a trust boundary. After you write or change code that handles untrusted input, authenticates, authorizes, queries a database, reads files, makes network calls, runs a subprocess, deserializes, or handles secrets or money — switch hats and try to break your own output…
Skill Claude CodeCodex
Match the house style when adding code to an existing codebase. Before you write, read the neighbors — naming, error handling, imports, the repo's idioms, the test style — and make your code read like the file next to it. Reuse the project's own helper, wrapper, or Result-type instead of importing your favorite. New…
Skill Claude CodeCodex
Anti-premature-"done". Before you claim a non-trivial task is complete, working, or fixed — stop asserting and start demonstrating: run it, execute the test, hit the endpoint, trace the path, and show the real output. "Done" means proven, not believed. If you genuinely can't run it, say exactly what's unverified and…
Skill Claude CodeCodex
Dependency gatekeeper. Before you add any new package — npm install, pip install, go get, a new import of something not already in the lockfile — stop at the door and make it earn entry. Ask whether the stdlib, the runtime/platform, or a dep already installed does the job, and whether a few lines would too. A…

Reviewable git hygiene for work you're about to commit or open a PR for. Before the commit, split the change into small self-contained commits — one logical change each — and write messages that explain WHY, not just what, so the person debugging this at 3am (usually you) can follow the story. Structure the diff so a…
Skill Claude CodeCodex
Anti-hallucination discipline for any code that names an external symbol you aren't certain exists — a library function, method, config key, package version, CLI flag, env var, or endpoint. Before you call it, cite it, or import it, confirm it's real: grep the codebase, read the installed package's actual signature…
Skill Claude CodeCodex
Chesterton's Fence for code you're about to delete or refactor. Before you rip out a weird retry, a seemingly dead branch, an ugly workaround, or a "redundant" check whose purpose isn't obvious — find out why it exists first. git blame it, find the callers, read the linked issue/PR/commit. If you can't explain why the…
Skill Claude CodeCodex
Anti-guessing discipline for ambiguous requests. Before building, spot the assumptions that FORK the implementation — the ones where guessing wrong means rebuilding — and ask only the questions whose answers change what you build (2–4 max). When a request is under-specified in a way that changes the design, ask first…
Skill Claude CodeCodex
Anti-sycophancy for build requests that encode a wrong assumption. Before you touch the keyboard, separate what the user ASKED for from what they're trying to achieve — and if the request bakes in a mistake (premature optimization, complexity bigger than the problem, cargo-culted pattern, solving the wrong problem)…
Skill Claude CodeCodex
Anti-thrashing circuit-breaker. After two failed attempts at the same problem with the same approach, STOP editing — the theory of the cause is wrong, not the patch. Re-examine assumptions, add instrumentation, and trace from the source before touching code again, instead of re-trying variations of the fix that…
