atomic-execution

atomic-execution is a skill for Claude Code from winstonkoh87/Athena-Public. It costs 20 tokens per session (515 once invoked), scanned A, original, MIT.

A task-execution process that breaks a development roadmap into small XML-defined tasks with named files, actions, checks, and completion conditions. XML is a structured text format used here to describe each task.

In plain words
What is it for?
Use it to execute a roadmap or design specification one focused task at a time, with explicit files, instructions, verification commands, and definitions of done.
Why use it?
It keeps long implementation work organized and requires each isolated task to pass its own verification step before the next one begins.

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-execution scanned grade A with 1 finding 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 10d 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.

What it actually says

Atomic Execution Engine

Prevents context degradation during long execution phases by breaking work down into atomic, verification-gated tasks using structured XML. Integrated via /steal from the get-shit-done methodology.

Triggers

"execute roadmap", "start building phase", "implement this plan", "atomic execution"

Core Mechanics

When entering Execution phase, do not build monolithic features linearly in one context window. Instead:

1. XML Plan Extraction

Convert the current phase of the ROADMAP.md (or the design.md spec) into 1 or more atomic XML execution plans. If the user hasn't provided one, draft it and execute it.

Format each atomic task precisely as:

<task type="auto">
  <name>Short descriptive name</name>
  <files>path/to/affected/file.ext</files>
  <action>
    Explicit, step-by-step instructions.
    Dependencies and logic.
  </action>
  <verify>Command to run to verify correctness (e.g. tests or curl)</verify>
  <done>Definition of done</done>
</task>

2. Isolated Execution

Execute ONE <task> block at a time. Maintain peak reasoning by not polluting the context window with previous tasks. If a task requires subagents or isolated worktrees, trigger /git-worktree-swarm.

3. Verification Gate

After code is written, explicitly run the command specified in <verify>. If it passes the <done> criteria, commit immediately using micro-commit. If it fails, fix the code within the same context before proceeding to the next <task>.

4. State Management

Update STATE.md after every completed XML task block to persist progress across sessions without bloating the context window. Always log:

  • Decisions made
  • Blockers encountered
  • Current position in ROADMAP.md

Reference Paths

  • spec-driven-dev (Pre-requisite for Execution via P107)
  • micro-commit (Post-Execution step)
Changes

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-execution is a skill published in the GitHub repository winstonkoh87/Athena-Public (587 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 515 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
