Happier Docs is an agent skill from happier-dev/happier. Create, update, reorganize, or review Happier internal technical documentation and published user/operator/contributor docs with evidence-backed product truth, exact release status, canonical-page ownership, human voice, minimal editing, and appropriate validation. Use whenever a change affects docs/, apps/docs/, or behavior that may make existing Happier documentation incomplete or false.
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Technical documentation. The repository describes itself as: Web, Desktop & Mobile client and orchestrator for Codex, Claude Code, OpenCode, Pi, Cursor, Grok, Antigravity, Kimi, Augment Code, Qwen, fully end-to-end encrypted. The licence is MIT.
8 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 1f03ccd. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
yarnFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use yarn, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Happier Docs loads about 2.7k tokens when it runs. Until then it costs about 103 tokens; SKILL.md has 1,396 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/happier-docs/SKILL.md (or your agent's skills folder).Keep documentation truthful, useful, current, and owned without turning every code change into prose churn. Follow the root constitution and, for published docs, apps/docs/AGENTS.md. For an explicit deep review or QA request, use .agents/skills/happier-review as the orchestrator and apply this skill as the documentation-domain standard; this skill does not create a competing general review workflow.
For the changed behavior or contract, decide whether it affects:
docs/**;apps/docs/content/docs/**;A refactor that leaves every documented contract unchanged may need no docs edit. A behavior, command, setting, support status, workflow, failure/recovery path, protocol, persistence shape, compatibility rule, deployment requirement, or canonical owner change normally does.
Classify published pages as task guide, concept, reference, troubleshooting, or development documentation. Internal docs explain architecture, contracts, ownership, and contributor-facing implementation constraints.
Search by the feature, command, setting, route, schema, provider/agent id, UI label, error, and reader phrasing before creating a page. Update, move, consolidate, or retire the canonical page instead of adding a parallel explanation. Map links, navigation, related pages, examples, and translations or screenshots that depend on the changed documentation contract.
Placement is part of authorship, not cleanup afterwards. A published page belongs to exactly one section, is listed in that section's meta.json at the point a reader should meet it, and is linked from that section's index.mdx. A page missing from either is unreachable in a way that breaks no link and shows up in no diff. Moving a page is the same four edits in reverse. The section inventory is in apps/docs/AGENTS.md.
Documentation is a claim, not proof. For Happier behavior:
README files, existing docs, changelogs, plans, issues, PR descriptions, commit messages, comments, and generated summaries are orientation. They do not independently prove that behavior is reachable or released.
For vendor-owned behavior, use current official vendor documentation and keep attribution with the claim. Do not state a competitor's limitation as Happier's own conclusion. Never invent product names, capabilities, support levels, guarantees, dates, quotes, or personal experience. Cut unsupported superlatives and comparisons.
Use .agents/skills/happier-compatibility when documentation claims depend on released/predecessor formats, mixed versions, upgrades, rollback, migrations, or persisted historical data.
Use the narrowest mode that serves the reader. Every added section or sentence must improve a decision, action, mental model, evidence boundary, or material caveat; prose that only restates another canonical owner does not earn its place:
An approved or preferred version becomes the baseline for later edits. A high change count in a correction pass is a warning sign, not evidence of quality. Every correction is a new claim: verify it as carefully as the text it replaces and do not swap one unsupported absolute for its opposite.
Before a substantial rewrite, inventory every material claim involving behavior, commands, settings, support, platforms, providers, compatibility, security, failure/recovery, readiness, and exact names. Account for each in the result. Humanizing is not summarizing.
Before drafting a reference table, check whether the same list already exists as structured data. Agent capabilities, feature flags, keyboard shortcuts, rate limits, download links and — where the plugin platform is present — runtime events, bundled plugins and the SDK's public surface all do. apps/docs/scripts/generateReference.mjs is the registry of what is generated today. Hand-maintained restatements of code are the single largest source of documentation drift in this repository, because nothing connects the data changing to the prose describing it.
Generate it, or link to the generated page. A generated page is compared against a fresh render on every build, so drift fails instead of shipping. Reserve hand-written prose for what a generator cannot produce: the mental model, the reason the mechanism exists, the failure modes, the judgement calls.
Two traps live inside the generators themselves. A hand-kept map of display names inside a generator drifts exactly like one inside a page — read the names from the source the app reads. And a declared field is not behaviour until you have found its consumer: publishing a flag whose value contradicts what the product does is worse than publishing nothing.
Where a capability is gated — a server feature flag, an experimental toggle, the account-level Experiments switch, a platform, a channel — the gate is part of the claim. Read uiFeatureRegistry.ts and features/catalog.ts rather than assuming availability, and state the gate where the reader meets the feature.
Write like a thoughtful builder helping another developer: warm, direct, concrete, and technically honest.
apps/docs/AGENTS.md — outcome lede, availability, prerequisites, the normal path, limits, failure modes, ## Related. A reader who has read one page should already know how to read the next.apps/docs/AGENTS.md: agents are Agents, provider is reserved for model/identity/voice/SCM providers, and a quoted UI label must match what the app renders today.Run the narrowest checks that can falsify the edit:
yarn --cwd apps/docs check:content — it resolves every internal link and #fragment, verifies that each documented Settings → … path names strings the app renders, and enforces the structural rules a reader feels but no compiler sees: every page listed in a meta.json, every section hub linking the pages beneath it, no cross-reference written as an unclickable code span, and no code-derived list drifting from its source. It runs inside the build, so these fail rather than ship; apps/docs/AGENTS.md lists what each check rejects;yarn --cwd apps/docs test for the guardrails themselves;yarn --cwd apps/docs types:check for published MDX/schema/TypeScript/generated-content changes;yarn --cwd apps/docs build when routing, navigation, generation, rendering, or production build behavior can be affected;Do not add wording-policing tests. Validate parsing, generation, routing, links, commands, and factual behavior rather than exact prose.
When you find a class of breakage that no check can see — not one broken page, but a shape of defect that could recur silently — add the check rather than only fixing the instances. Every check in checkContent.mjs exists because its defect shipped and then stayed shipped. Give the new check a hard failure when its own input goes missing from inside this package: a check that skips on a missing directory is indistinguishable from a check that passes, and will read green through the next rename.

Happier Docs fits situations like: A change affects docs/; behavior that may make existing Happier documentation incomplete.
Run `npx skills add happier-dev/happier --skill happier-docs -a claude-code`. Or copy the skill folder (.agents/skills/happier-docs in happier-dev/happier) into .claude/skills/happier-docs in your project. Claude Code loads it when a task matches its description.
Run `npx skills add happier-dev/happier --skill happier-docs -a codex`. Or copy the skill folder (.agents/skills/happier-docs in happier-dev/happier) into .agents/skills/happier-docs in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add happier-dev/happier --skill happier-docs -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/happier-docs, .gemini/skills/happier-docs, .github/skills/happier-docs and .opencode/skills/happier-docs in your project.
Going by SKILL.md and its folder, Happier Docs needs the command-line tools its instructions call (yarn).
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Happier Docs is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.7k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
