HAPPY_STACKS_EDISON_WRAPPER

HAPPY_STACKS_EDISON_WRAPPER is an agent for coding agents from happier-dev/happier. It costs 0 tokens per session (311 once invoked), scanned A, original, MIT.

Repository instructions requiring Edison commands to run through the `hstack` wrapper in the happier-dev project. The wrapper preserves the correct stack and worktree context.

In plain words
What is it for?
It is for running Edison tasks, capturing evidence, validating quality, and creating or managing parent tasks, tracks, and components through `hstack`.
Why use it?
It prevents commands from running against the wrong project context and defines the project’s task structure and fail-closed rule.

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

HAPPY_STACKS_EDISON_WRAPPER 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 3d 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.

What it actually says

hstack: Edison wrapper (MANDATORY)

This repo (happier-dev) is a hstack project. Edison must be invoked via the hstack wrapper so stack/worktree context is enforced.

Fail-closed rule

  • Do not run edison ... directly.
  • Always run Edison via:
    • hstack edison -- <edison args...>
    • hstack edison --stack=<stack> -- <edison args...> (recommended for tasks/evidence/validation)

Copy/paste mapping

  • edison task listhstack edison -- task list
  • edison task status <id>hstack edison --stack=<stack> -- task status <id>
  • edison evidence capture <id>hstack edison --stack=<stack> -- evidence capture <id>
  • edison qa validate <id>hstack edison --stack=<stack> -- qa validate <id>

hstack task model (MANDATORY)

  • Parent (hs_kind: parent): planning umbrella (not claimable)
  • Track (hs_kind: track): owns one stack per track
  • Component (hs_kind: component): owns one component under a track

Recommended one-shot setup:

hstack edison task:scaffold <parent-task-id> --mode=upstream|fork|both --yes

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.
