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 | $0.00055 | $0.00784 |
| Opus 5 | $0.00028 | $0.00392 |
| Sonnet 5 | $0.00011 | $0.00157 |
| Haiku 4.5 | $0.00006 | $0.00078 |
Grade A, and why
happier-release 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Happier Release
Keep release policy simple: test source once, admit the operation cheaply, build immutable candidates once, verify once per trust boundary, promote independent products in parallel where the workflow permits, and recover without rebuilding valid work.
Resolve authority first
Inspect the public machine-readable contract with:
node scripts/pipeline/run.mjs release-contract
Then resolve the private release authority for the absolute checkout:
hmaint release bootstrap --repo <absolute checkout> --json
Use the returned private skill and its instructions as authoritative. The public contract defines targets, profiles, and compatibility intent; private operating procedure stays outside this repository.
Do not publish from a dirty or protocol-incompatible maintainer-tools checkout. Bootstrap/preflight must bind the maintainer-tools commit and return structured admission failures before any release mutation. Do not modify or clean that checkout as an implicit part of releasing.
Admit without repeating CI
Before expensive candidate work, run the repository's cheap, non-mutating release preflight. It validates operation-specific inputs such as source/channel identity, version and notes projection, maintainer protocol compatibility, tools, credentials, external configuration, and selected runner/platform prerequisites. It must call canonical owners and must not repeat unit, typecheck, integration, or E2E work from source CI.
Consume an explicit successful exact-SHA CI run/attestation whenever available. Pass its numeric ci_run_id; the release verifier must bind repository, canonical workflow, event, branch, completion, success, and exact head SHA. Nightly release validation remains artifact-specific and risk-selected—it is not another full source-CI run. If source CI is absent, fail or defer quickly through the canonical fallback instead of keeping a release runner watching another workflow.
Keep fast, release, and deep profile ownership distinct as defined in CI cleanup. Do not turn a profile or runner backend into a copied workflow.
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 is a skill published in the GitHub repository happier-dev/happier (1,624 stars, last pushed yesterday), licensed MIT. It adds 55 tokens to every session and 784 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 2026-09-03.
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.
