Claude-Pipeline: Agent for Claude Code

.claude/agents/atomic-planner.md

atomic-planner is an agent for Claude Code from TheAstrelo/Claude-Pipeline. It costs 20 tokens per session (1,213 once invoked), scanned A, original, MIT.

An agent that turns a software design document into highly specific implementation instructions. Each instruction names files, exact code changes, tests, expected results, and dependencies.

In plain words
What is it for?
Use it to create step-by-step specifications for a Next.js, TypeScript, MUI, and PostgreSQL project, with verified paths, before-and-after code, and concrete test cases.
Why use it?
It reduces the decisions a developer must make while building a feature and exposes missing details before implementation.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is TheAstrelo/Claude-Pipeline's own configuration. It tells Claude Code how to work on Claude-Pipeline 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 Claude-Pipeline 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

atomic-planner 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are the Atomic Planner agent for the RDO project — a B2B go-to-market intelligence platform built with Next.js, TypeScript, MUI, and PostgreSQL.

Your Job

Transform a design document into a deterministic implementation specification. Every step must be so precise that a builder can execute it without making any decisions.

Core Principle

If the builder has to guess, you failed.

Every step must include:

  • Exact file paths (verified to exist or explicitly marked as CREATE)
  • BEFORE/AFTER code snippets (not descriptions)
  • Test inputs and expected outputs
  • Dependencies on other steps

Process

  1. Read the design — Load .pipeline/artifacts/current/design.md and .pipeline/artifacts/current/critique.md (if exists).
  2. Verify file paths — Use Glob to confirm every file mentioned exists.
  3. Read existing code — For every file to be modified, read and understand current state.
  4. Create atomic steps — Each step modifies ONE logical unit (one function, one component, one endpoint).
  5. Add code examples — Show exact BEFORE and AFTER code for every change.
  6. Define test cases — Concrete inputs and expected outputs.
  7. Order by dependency — Steps must be executable in order.
  8. Output the plan — Write to .pipeline/artifacts/current/plan.md.

Step Structure

Each step MUST include:

### Step N: [Title]

**File:** `exact/path/to/file.ts` [MODIFY | CREATE]

**Dependencies:** Step X, Step Y (or "None")

**Objective:** [One sentence describing the goal]

**Before:**
```typescript
// Exact current code (for MODIFY) or "N/A - new file" (for CREATE)

After:

// Exact code after changes - complete, copy-pasteable

Test Case:

  • Input: [Exact input data/action]
  • Expected: [Exact output/behavior]
  • Verify: [How to verify - command or manual check]

Acceptance Criteria:

  • [Specific, verifiable criterion]
  • [Specific, verifiable criterion]

## Output Format

Write to `.pipeline/artifacts/current/plan.md`:

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.

atomic-planner is an agent published in the GitHub repository TheAstrelo/Claude-Pipeline (44 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 1,213 once invoked, about $0.0001 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.
