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.

SkillSpector: 5 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Privilege Escalation · line 8 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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 | $0.00063 | $0.06343 |
| Opus 5.5 | $0.00025 | $0.02537 |
| Sonnet 5.5 | $0.00013 | $0.01269 |
| Haiku 4.5 | $0.00006 | $0.00634 |
Grade A, and why
happier-github-ops 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 17d 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.

Happier GitHub Ops (bot gh wrapper)
This repo provides yarn ghops as the canonical isolated transport for GitHub API/UI reads and mutations as the bot, plus an explicit bot-authenticated branch-push capability. Ordinary commits and pushes still use the current machine's configured Git identity, remote, and credentials; ghops git push is an authorization-gated exception, never the default. ghops forces authentication via the bot Personal Access Token. HAPPIER_GITHUB_BOT_TOKEN has highest priority. Without that override, macOS reads the validated token from Keychain service happier/ghops, account happier-bot; a managed Linux workspace receives that same credential from the short-lived execution-host broker through its active mac-host target while keeping repository work on the authoritative Linux checkout. The broker exposes only this fixed credential over a user-only Unix socket and never places the token in the guest environment or on disk.
Prerequisites
ghis installed on the host and reachable onPATH.- Either environment variable
HAPPIER_GITHUB_BOT_TOKENis set to the bot's fine-grained PAT, or the token was stored on macOS withyarn ghops auth store. - Repository issue mutations require the fine-grained PAT permission Issues: Read and write for the target repository. The bot account's repository role and GraphQL
viewerCanUpdatefields do not prove that the resolved token grants write operations. - Ordinary branch pushes require the current machine's normal Git credentials. An explicitly authorized bot push requires Contents: Read and write plus repository/fork permission to update the exact target branch; lack of machine access alone does not authorize that exception.
Contract / Safety
yarn ghops ...refuses to run if neither the environment override nor the macOS Keychain credential is available locally or through the active execution-host broker andmac-hosttarget.- Runs non-interactively (
GH_PROMPT_DISABLED=1). - Uses an isolated repo-local
GH_CONFIG_DIRby default. - Never falls back to personal
gh,GH_TOKEN, orGITHUB_TOKENcredentials. - Forces
GH_HOST=github.comso an inherited host override cannot redirect the bot token. auth storevalidates that the token belongs tohappier-botbefore persisting it.- Every ordinary invocation revalidates that the resolved token belongs to
happier-botbefore forwarding the requested command.
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-github-ops is a skill published in the GitHub repository happier-dev/happier (2,072 stars, last pushed yesterday), licensed MIT. It adds 63 tokens to every session and 6,343 once invoked, about $0.0003 per session on Opus 5.5. 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.

cmux-release
Prefer the /release command. It determines the new version (minor by default), gathers the Changelog line from each PR merged since the last stable tag, updates CHANGELOG.md, runs ./scripts/bump-version.sh, commits, runs ./scripts/release-pretag-guard.sh, then tags and pushes.

Contributor workflow for native cmux setup, tagged dev builds, Xcode project normalization and sidebar extensions. Use for native build inputs, setup or tagged app verification.
prs
Expertise in managing the Git and GitHub Pull Request lifecycle, including staging changes, generating PR descriptions, and branch management.
