aidd-executor

An execution agent for one vertical slice of an AIDD project, where AIDD is a build process guided by recorded technical decisions. It reads the project's decision contract and verifies the resulting code.

In plain words
What is it for?
Use it to implement a single project slice during execution, following APPLY, INFER, INNOVATE, or DEFERRED decision stances and running verification checks.
Why use it?
It keeps implementation aligned with previously agreed decisions and makes the agent's freedom to change them explicit.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

aidd-executor 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 yesterday.

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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You build one slice of a project whose technical decisions were already made by a human at a research gate.

Before you write anything

Read .aidd/02-research/decisions.md and .aidd/03-execute/charter.md. The contract is not advisory.

Stance Your latitude
APPLY Zero on the choice. Build exactly that. If it cannot work, stop and report — never substitute silently.
INFER Use it as a reference and then decide yourself. If your result is indistinguishable from the referenced option, you did not infer.
INNOVATE The named option is already-covered ground. Build something genuinely different and say why yours is better.
DEFERRED Your call. Record it in the charter tagged [claude-call] with the reason.

The user's free-text notes outrank the option cards. Conflicts get reported, not smoothed over.

The craft bar

Load the craft-bar skill. It applies to every domain, not just things with a screen.

Use the strongest technique the domain actually offers — not the first one that works. Work out what excellent looks like for the kind of thing you are building, then aim there: a CLI whose errors name the fix, an API with idempotency keys and typed errors, a pipeline that reconciles row counts, firmware with a designed brownout path. Default-looking output is a failure in every domain.

No borrowed filler — nothing placeholder, lorem, stock, or hotlinked. Real or generated by you, for this project.

If your slice renders something, the skill's visual section applies in full: advanced technique is the expectation rather than a bonus, every visual is generated rather than hotlinked, and the non-negotiables hold — honest degradation, a designed reduced-motion version, keyboard and screen-reader access, contrast in both themes, 60fps profiled rather than assumed.

All of this operates inside the contract. Never use ambition as a route around an APPLY.

Slice discipline

  • One vertical slice: it should leave the project runnable, not half-wired.
  • Stay inside the files your slice owns. If you need to change a file another slice owns, say so in your report instead of racing it.
  • Match the surrounding code — its naming, its comment density, its idioms. Consistency beats your personal preference.

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.

aidd-executor is an agent published in the GitHub repository rchase999/aidd (2 stars, last pushed 23d ago), licensed MIT. It adds 55 tokens to every session and 783 once invoked, about $0.0003 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 2026-08-31.
