What is eou-foundry-init?

A scaffolding tool for starting a new EOU-governed application. Scaffolding creates the initial folders and files, while EOU governance supplies rules for how the application's work is specified and managed.

Use it when initializing a new application with a valid lowercase name, optionally adding a description and choosing whether to create a Git repository.

It creates the required project structure and starter governance files consistently, while refusing to overwrite an existing directory.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00059	$0.01081
Opus 5	$0.00030	$0.00541
Sonnet 5	$0.00012	$0.00216
Haiku 4.5	$0.00006	$0.00108

Security

Grade A, and why

eou-foundry-init 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 6d 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.

Initialize EOU-Governed Application

You are scaffolding a new EOU-governed application. The user is invoking this from a workspace directory and should supply an app name.

1. Get the app name

If the user supplied an app name in their request, use it. Otherwise ask: "What is the application's slug name? (lowercase, alphanumeric + hyphen)"

Optional inputs:

A one-line description of what the application does (defaults to the slug)
NO_GIT=1 — set this environment variable before the command to skip git init in the new directory (default: initialize git)

Validate the slug. Reject names containing /, \, .., a leading ., or any character outside [a-z0-9-]. Refuse to overwrite an existing directory.

2. Run init script

${PLUGIN_ROOT} is the Codex runtime env var for the plugin root. The Claude Code equivalent is ${CLAUDE_PLUGIN_ROOT}. Both resolve to the same directory — the name differs by runtime.

Run bash "${PLUGIN_ROOT}/scripts/init_app.sh" "$APP_NAME" "$DESCRIPTION" $([ "$NO_GIT" = "1" ] && echo "--no-git") and let the script handle the existence check and scaffolding atomically. Report what it produced.

3. What the script does (for reference)

scripts/init_app.sh is idempotent in the sense of "refuse to clobber":

Refuses if ./<app-name>/ already exists.
Creates ./<app-name>/ and inside it:
- foundry/ populated from templates/ — constitution, governance, registry (empty), maturity-model, failure-taxonomy, refactoring-patterns, runtime-contract, meta-eous/, templates/eou-template, templates/generating-eou-template.
- foundry/eous/, foundry/incidents/, foundry/audits/, foundry/runs/, foundry/self-evolution/{ecp/{proposed,approved,implemented,rejected},regression/cases,upstream/proposed-to-plugin}/ empty.
- CLAUDE.md, AGENTS.md, GEMINI.md minimal starters.
- .claude/settings.json minimal scaffold (no hooks).
- .gitignore with the standard AI-tool ignores.
- README.md one-paragraph application overview.
Substitutes {{APP_NAME}} and {{DESCRIPTION}} placeholders in the template files.
Unless --no-git, runs git init and makes a single initial commit.
Runs python3 "${PLUGIN_ROOT}/scripts/validate_foundry.py" against the new app to confirm the scaffold passes the schema check.

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.
