claude-boris: Skill for Claude Code

.claude/skills/boris-workflow/SKILL.md

boris-workflow is a skill for Claude Code from llcoolblaze/claude-boris. It costs 38 tokens per session (1,061 once invoked), scanned A, original, MIT.

A documented development workflow based on Boris Cherny's approach to working with Claude Code. It covers planning, delegating work, checking results, and recording lessons for future sessions.

In plain words
What is it for?
Use it to organise complex development tasks, set up verification loops, and maintain project guidance in CLAUDE.md.
Why use it?
It gives coding tasks a repeatable process so work is planned before changes are made and verified afterwards.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

boris-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Boris Workflow Methodology

This skill documents the workflow used by Boris Cherny, creator of Claude Code. Use these principles when orchestrating development tasks.

Core Principles

1. Plan First, Execute Second

"Most sessions start in Plan mode. Go back and forth until I like the plan. From there, auto-accept and Claude can usually 1-shot it."

Implementation:

  • Always create a written plan before coding
  • Get explicit approval before proceeding
  • Plans should include: goal, steps, verification strategy
  • A good plan enables 1-shot execution

2. Verification is Everything

"Give Claude a way to verify its work. If Claude has that feedback loop, it will 2-3x the quality."

Implementation:

  • Every change must pass automated checks
  • Tests, types, lint, build - all must pass
  • Manual verification for UI changes
  • Never skip verification to save time

3. Living Documentation

"Anytime we see Claude do something incorrectly we add it to CLAUDE.md, so Claude knows not to do it next time."

Implementation:

  • Update CLAUDE.md after every mistake
  • Document patterns that work well
  • Keep commands and processes current
  • This compounds over time

4. Delegate to Specialists

"I use subagents regularly: code-simplifier, verify-app, and so on."

Implementation:

  • Use Task tool to invoke specialist agents
  • Match agent to task type
  • Don't do everything yourself
  • Specialists have focused expertise

5. Automate the Inner Loop

"I use slash commands for every workflow I do many times a day."

Implementation:

  • Create commands for repeated workflows
  • Commands should be self-contained
  • Pre-compute context with inline bash
  • Check commands into git for team sharing

The Boris Orchestration Pattern

When handling a task as the Boris orchestrator:

1. UNDERSTAND
   - Parse the user's request
   - Identify implicit requirements
   - Assess scope and complexity

2. PLAN
   - Create detailed execution plan
   - Identify which agents to use
   - Define verification criteria
   - Present plan for approval

3. EXECUTE
   - Delegate to appropriate agents
   - Maintain coordination
   - Handle failures gracefully
   - Track progress

4. VERIFY
   - Run all automated checks
   - Invoke verify-app agent
   - Use code-simplifier to clean up
   - Iterate until all checks pass

5. SHIP
   - Commit with good message
   - Create PR with context
   - Update CLAUDE.md if learned something
   - Report completion

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

boris-workflow is a skill published in the GitHub repository llcoolblaze/claude-boris (48 stars, last pushed 7mo ago), licensed MIT. It adds 38 tokens to every session and 1,061 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
