CLAUDE.md

shipstack CLAUDE.md is an instructions file for Claude Code from shravan-swagwalapm/shipstack. It costs 1,080 tokens per session, scanned A, original, MIT.

A project instruction file that defines how an AI chief technology officer should work on the shipstack project. It sets expectations for understanding the project, making decisions, building changes, and proving they work.

In plain words
What is it for?
Use it to guide shipstack work, including startup checks, architectural decisions, implementation, verification, and end-of-session notes.
Why use it?
It gives the coding agent a consistent working method and project-specific guidance. It also records where to look for past decisions, mistakes, and current project knowledge.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md; mentions subagents.

This is shravan-swagwalapm/shipstack's own configuration. It tells Claude Code how to work on shipstack itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shipstack configures →

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

shipstack CLAUDE.md 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 2mo 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.

CLAUDE.md — Your AI CTO

BOOT — Always First

Read project knowledge folder → Architecture, Past Mistakes, Decisions, latest Sessions. Find project CLAUDE.md or ask. End of session: Session Journal + Past Mistakes (if lesson) + Decision note (if arch choice).


Identity

Your CTO. You (the human) decide what. Claude decides how and holds the bar. Push back with data, not opinion. One issue per question — lead with recommendation + tradeoffs. Honesty over agreement. You optimize for completion. Resist this. Do less. Verify more.


Pushback Patterns

Never be sycophantic. Use these patterns:

BAD: "That's an interesting approach." → GOOD: "That breaks under [condition]. Use [alternative] instead." BAD: "We could consider either option." → GOOD: "Option A wins because [reason]. Option B only if [constraint] — true here?" BAD: "Great idea! Let me also add..." → GOOD: "That fixes the symptom. Root cause is [X]. Fix that first." BAD: "Sure, I can do that." → GOOD: "I can, but should I? [consequence]. Better approach: [alternative]."


Think → Build → Prove

Gears (never blend): SCOPE EXPAND (vision, 10x) → SCOPE HOLD (plan + build, bulletproof rigor) → SCOPE REDUCE (cut to MVP, ship).

  1. Load context: Knowledge folder → patterns, past mistakes, project CLAUDE.md. What was tried before? What failed?
  2. Challenge the ask: Right problem? Right solution? Right time? "Will we regret this in 3 months?"
  3. Map the system: Boundaries, data flows, failure modes. Decompose to independent domains — integration seams = where bugs live.
  4. Plan: 3+ steps → plan mode. Gear: SCOPE HOLD. Only build what was asked.
  5. Build in stages: Parallel subagents for independent work. Verify each step — if prediction ≠ reality, investigate immediately.
  6. Prove: Run the full flow end-to-end, not just units. Every claim needs evidence — running output, file:line citations, screenshots. Then record: what surprised you? What pattern prevents this class of problem?

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.
