Happier is an open-source, end-to-end encrypted client that lets people run AI coding-agent sessions on a computer and continue controlling them from a phone, browser, or desktop app. It is for developers who use agents such as Claude Code, Codex, Gemini, or OpenCode across multiple devices, with self-hosting available. The catalogue entries are add-ons for configuring or extending this client and its supported coding-agent workflows.

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 | $0.00034 | $0.01116 |
| Opus 5 | $0.00017 | $0.00558 |
| Sonnet 5 | $0.00007 | $0.00223 |
| Haiku 4.5 | $0.00003 | $0.00112 |
Grade A, and why
happier-release-notes 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.
How it starts
The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Happier Release Notes
This skill owns only source-coupled release-note mechanics: the canonical changelog section schema, bounded-channel projection, StoryDeck cards, translations, assets, and generation. It does not choose release scope, group changes, write editorial prose, recommend patch/minor/major, approve content, or dispatch a release.
For those decisions, start with the private maintainer release authority:
hmaint release bootstrap --repo <absolute checkout> --json
Read first
- Read
apps/ui/release-notes/README.mdandapps/ui/release-notes/releases/README.md. - Inspect
apps/ui/sources/changelog/releaseNotes/types.tsandapps/ui/sources/components/ui/storyDeck/storyDeckCardLimits.tsbefore changing card data or limits. - If UI behavior changes, use the canonical UI testkit and TDD.
Canonical changelog and bounded projections
apps/ui/CHANGELOG.md is the single authored authority for one release's
public Markdown and exact bounded channel text. Put this JSON comment at the
start of the matching ## Release <project-release-id> - <date> section. The
project release ID is a unique lowercase identifier such as 2026-08-09.1,
independent of every component version. Use the date plus an ordinal, increase
the ordinal for another release on that date, and keep the same ID from preview
through stable. The heading is the only authored source; a workflow
input only selects and verifies it:
<!-- happier-release-note-projections:v1
{
"expo": { "message": "Approved Expo text." },
"appStore": { "whatsNew": "Approved App Store text." },
"playStore": { "whatsNew": "Approved Play Store text." },
"storyDeck": { "summary": "Approved StoryDeck text." }
}
-->
## Public heading
Approved public Markdown follows here.
The comment is removed from the GitHub/rolling Markdown projection. The script publishes every bounded string exactly as authored—there is no truncation, translation, synthesis, or AI rewrite. Expo is the currently consumed required projection. App Store, Play Store, and StoryDeck projections are optional until the selected release surfaces consume them; when present they are validated. Limits are: Expo 1,024; App Store 4,000; Play 500; StoryDeck 280. The section must contain meaningful public Markdown after the comment.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

happier-release-notes is a skill published in the GitHub repository happier-dev/happier (1,624 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 1,116 once invoked, about $0.0002 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 2026-09-03.
Other skills, from other repositories
release
Use this skill for EVERY ClawRouter release. Enforces the full checklist — version sync, CHANGELOG, build, tests, npm publish, git tag, GitHub release. No step can be skipped.
release
Release a new version of the DevoxxGenie IntelliJ plugin — prompt for the target version, bump it in the build files, write a curated CHANGELOG.md entry and plugin.xml change-notes from the git/PR history since the last tag, build to verify, then commit, tag, and publish a matching GitHub release. Use this whenever…
close-task-commit-push-pr
Close the active backlog task (detected from branch name), commit all changes, push to remote, and open a pull request. Use when the user says "close task and ship it", "close task commit push pr", or invokes /close-task-commit-push-pr.
release
Prepare, verify, and publish Sutando engine releases. Use when asked to prepare a release proposal, determine a version bump, audit release documentation, validate release gates, create a release PR, tag a confirmed release, or publish GitHub release notes. Preparation is safe and non-publishing; tagging and…
cmux-release
Prefer the /release command. It determines the new version (minor by default), gathers commits since the last tag, updates CHANGELOG.md, runs ./scripts/bump-version.sh, commits, runs ./scripts/release-pretag-guard.sh, then tags and pushes.
update-v8-version
Update Codex's pinned v8 / rustyv8 versions, validate the release-candidate path, and investigate failed V8 canary or artifact builds. Use when asked to bump V8, update rustyv8 artifacts, prepare or validate a V8 release candidate, check v8-canary, or diagnose why a V8 version update no longer builds.
