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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00311 |
| Opus 5 | $0.00000 | $0.00156 |
| Sonnet 5 | $0.00000 | $0.00062 |
| Haiku 4.5 | $0.00000 | $0.00031 |
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 list→hstack edison -- task listedison 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.

HAPPY_STACKS_EDISON_WRAPPER is an agent published in the GitHub repository happier-dev/happier (1,615 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 311 tokens. 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.
