What do you mostly use Claude Code for?

Same eight skills whichever you pick -- this just shows where to start.

Or see all eight skills.

Solo builder

You are the whole team. Your agent should not be the part that breaks things.

It tells you the plan is great, because agreeing is what it was trained to do.
It declares the feature done, and nothing checked.
On a long run it can reach for a shell command you cannot undo.

Start with these, in this order:

self-verifying-loops -- decide whether a loop is worth building at all (four conditions), give it a stop signal it cannot fake, and spot a loop that is stuck from outside it.
agent-bash-security -- five levels of locking down the shell, and the rule for which one a task needs.
adversarial-self-critique -- get a real judgment on your plan instead of agreement.
context-curation -- keep a long session sharp instead of letting it fill up and drift.

Not for you if you have not used a coding agent yet -- start there first.

Team lead reviewing agent-written code

The tests pass. That is no longer the question.

Agent-written changes arrive faster than anyone can read them line by line.
The explanation in the pull request sounds right whether the code is right or not.
The same CLAUDE.md rule gets ignored session after session.

Start with these, in this order:

review-ai-code -- a 9-step ordered review and a pre-merge checklist, what to do when a diff outgrows the reviewer, and how to make an automated reviewer rank its findings and give a verdict.
claude-md-rules -- a 13-rule template to pick from, and the two mechanical reasons a rule looks ignored.
multi-agent-finisher -- builder and judge as separate roles, seven shapes for multi-agent work, bounded revision.
agent-bash-security -- separation of duties: the reviewer cannot act, the actor cannot approve.

Not for you if nobody on your side writes code with an agent yet. The license is single-seat -- ask about a team license.

Building with Claude Code without reading code

You can't read the code. You can still make the agent prove it works.

"Done" from the agent is a claim, not a check.
It agrees with whatever you asked for, including the part that was a bad idea.
It can run commands on your machine that you would not know to stop.

Start with these, in this order:

self-verifying-loops -- make the agent show that something works, with a stop signal it cannot talk its way past.
adversarial-self-critique -- ask for the strongest case against your idea before building it.
agent-bash-security -- safe settings for the shell, laid out as levels from weakest to strongest.
claude-md-rules -- a short instruction file that stops the same mistake happening every session.

Honest limit: review-ai-code is written for people who read code, so parts of it will not apply to you. Not for you if you have not run Claude Code on a real project yet.

Your agent is fast. That's the problem.

A coding agent will happily agree with your bad idea, write code that passes the tests but is not safe to ship, run a destructive shell command on a long unattended run, and loop forever declaring false victory. These eight skills are the guardrails.

It agrees with you instead of telling you the plan is wrong.
It ships plausible-looking code with security and edge-case bugs the tests miss.
It burns your context window on everything "just in case" and gets dumber.
It runs unattended with no self-check and no escape hatch.

What's inside

Eight skills, each a single SKILL.md your agent loads on demand. No install step, no dependencies, nothing to run -- they encode how to get reliable results.

01adversarial-self-critique

Defeat sycophancy -- get a real judgment on an idea, plan, or the agent's own work instead of the model agreeing with you.

02review-ai-code

Review AI-generated code like a senior developer: a 9-step ordered review + pre-merge checklist that catches bugs that pass the tests but are not safe to ship.

03self-verifying-loops

Build an unattended agent loop that prompts itself, checks its own work, and stops or escalates -- with the non-negotiable escape hatch.

04context-curation

Choose the smallest sufficient context per step instead of dumping the whole window, so the agent stays sharp and cheap.

05claude-md-rules

Write a CLAUDE.md the agent actually follows -- a behavioral contract of imperative rules, each closing a specific failure mode.

06multi-agent-finisher

Make a multi-agent system converge on a finished result (Researcher, Builder, Judge, Manager; builder is not the judge; bounded revision).

07agent-bash-security

Lock down the most dangerous tool an agent has -- the shell -- so a long autonomous run cannot do something irreversible.

08skill-authoring

Turn any repeating workflow into a durable Agent Skill in the real Anthropic format, and refine it so it compounds.

Who it's for

Developers and teams already using Claude Code, Codex, or another coding agent day to day, who are past "it writes boilerplate" and want the agent's work to be reliable enough to trust -- and people who build with Claude Code without reading the code it writes. If you have never opened a coding agent, start there first -- this pack assumes you already run one.

How it works

1. Buy and download the pack. 2. Drop a skill folder into ~/.claude/skills/ (all projects) or your repo's .claude/skills/ (one project). 3. Invoke it by name or let the agent auto-load it when your request matches. That's it -- they're plain markdown.

Field notes

The reasoning behind the skills, published in full and free to read. Each one is a specific failure, checked against Anthropic's own documentation or observed directly rather than assumed.

Your skill stops working in long sessions — Skill bodies are truncated after compaction, and truncation keeps the start of the file.
A CLAUDE.md rule that worked and then stopped — Path-scoped rules do not survive compaction. The project-root file does.
Your scheduled task says it succeeded and did nothing — A run that produces no output is not missing, not stuck and not failed. The fourth check.
Your cron job fired on the wrong day — Day-of-month and day-of-week are OR-ed, plus dispatch offsets and catch-up runs.
Your agent stalled and you lost the work — You probably did not. Flush per item, then finish from the file.
Why Claude ignores your CLAUDE.md — Four reasons a rule does not hold, a scope-gap test, and a drift canary.
Your agent agrees with everything you say — Why a coding agent validates a bad plan, and how to get a real judgment instead.
Auto mode: what actually changed — The permission mode that now starts by default, and which of your allow rules it drops.

FAQ

Do I need to be a developer?

No, but you need to already use a coding agent (Claude Code or similar). The skills assume you run one; they make its output reliable. One skill, review-ai-code, is written for people who read code.

Is this software? Do I install anything?

No. Each skill is a single markdown file (a procedure the agent reads). You copy it into a skills folder -- no dependencies, nothing to run.

Does it only work with Claude?

It's written for Claude Code, but the Agent Skill format is plain markdown, so it works with any harness that reads skills. The techniques are largely model-agnostic.

Can I share it with my team?

The license is single-seat -- use it yourself and on your own projects. Reselling or redistributing the files is not permitted. For a team license, reply to any Gumroad receipt or starter-kit email from ResilientMindset.

Can I get a refund?

Yes. If the pack is not useful, reply to your Gumroad receipt within 30 days for a full refund.

Will it be updated?

Yes -- buyers get free updates to this pack. The 2026-09-17 update expanded all eight skills and more than doubled the pack overall.
