Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add happier-dev-happier-implement
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("happier-dev-happier-implement")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install happier-dev-happier-implement

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/happier-dev-happier-implement/SKILL.md https://app.decimal.ai/s/happier-dev-happier-implement/SKILL.md

Copy SKILL.md

Save it in your project, as

.claude/skills/happier-dev-happier-implement/SKILL.md

This gets SKILL.md only. The skill's 1 other file is not included.

Happier Implement

Implement the requested outcome through the real owner and consumed runtime path. This skill owns the common change workflow; it does not create plans, authorize plan deviations, conduct a review-only program, or turn a diagnosis request into source edits.

1. Normalize the change and authority

Classify the requested work as a feature/change, bug fix, refactor/migration, mechanical transformation, or accepted review fix. Confirm that the user requested implementation rather than assessment, diagnosis, planning, or review only.

For an approved plan, also use .agents/skills/happier-implement-plan; that skill supplies the authoritative contract, execution units, state, and amendment rules.
For an accepted review finding, preserve the review's adjudicated impact and authority, then choose the coherent implementation rather than copying the reviewer's proposed mechanism blindly.
For a runtime/session/provider/auth investigation without source changes, use .agents/skills/happier-diagnose.
For read-only GitHub issue grouping or diagnosis, use .agents/skills/happier-issue-triage and .agents/skills/happier-issue-diagnose. Enter this implementation workflow only after the user authorizes source changes, carrying forward the established issue evidence and version basis.
For a reported defect or regression, read bug-fix-loop.md before editing production behavior.
When the repository constitution defines a successor-line obligation, include a destination disposition in the complete outcome. Work on and validate one coherent source batch first, then invoke the owning port workflow once at that boundary. Reuse current-basis diagnosis and port evidence, and revisit only changed intents unless scope, ownership, or architecture materially changed; do not port or reanalyze the destination during every source edit.

Do not create a repository plan on agent initiative. Use an internal checklist when useful, but keep it ephemeral unless an approved program already designates durable tracking.

2. Establish the complete outcome backward

State the real intent, exclusions, and outermost observable result. Derive the implementation backward:

name the user-visible, operational, compatibility, and architectural truths that must hold;
identify the canonical owners or artifacts that establish each truth;
identify the real entry points, consumers, wiring, migrations, removals, and compatibility paths required to make those owners authoritative;
identify the two or three links whose failure would be most damaging or least visible;
choose deciding evidence that observes the truths at the outermost practical contract surface.

Imports, registrations, types, file existence, mocked wiring, and helper tests are supporting evidence. They do not complete a user flow, CLI/API contract, persisted-state transition, process lifecycle, provider integration, or published artifact when that real surface is runnable.

Preserve every authorized outcome: integration, migration, removals, compatibility, UX, accessibility, security, privacy, performance, platform behavior, testing, and validation. Solution economy simplifies the implementation inside that boundary; it never reduces the boundary.

3. Discover the current owner and affected corridor

Before production changes, inspect enough current evidence to name:

the canonical owner and why the behavior belongs there;
inputs, normalization, callers, producers, consumers, readers, writers, and user-visible outputs;
state, persistence, lifecycle, schema, feature, provider, compatibility, and platform seams that are materially coupled;
existing tests, testkits, live recipes, and generated outputs;
same-concept split-brains, bypasses, legacy paths, parallel decisions, and planned removals;
current relevant diff and compatible uncommitted work that must be preserved.

Search by symbols and domain identifiers, not filenames alone. Stop once the material owner, corridor, risks, and deciding checks are established; do not keep searching for reassurance.

Dirty or concurrently edited files are normal and do not establish ownership. Inspect current bytes, preserve compatible changes, and layer in-scope work on top. Coordinate only actual same-hunk edits, incompatible decisions at one conceptual seam, destructive moves, single-producer generated outputs, or exclusive runtime resources.

4. Select the smallest coherent systemic change

Apply root Scope-preserving solution economy at implementation time: preserve the complete feature outcome, challenge unsupported machinery rather than the feature itself, and fold behavior into the canonical owner through reuse, refinement, consolidation, or refactoring before adding another path.

Prefer, in order, to add nothing when the complete outcome already holds; correct/reuse/refine/consolidate the canonical owner; use the language or platform; use an existing package-owned dependency; or add the smallest clear consumed implementation.

Smallest coherent does not mean smallest diff. Update every materially affected caller, reader, writer, consumer, platform path, and compatibility direction. Remove or migrate active competing owners and bypasses when the authorized outcome makes them obsolete. Do not centralize coincidental similarity across distinct bounded contexts or absorb unrelated debt.

Before adding a protocol, registry, table, state machine, gate, lease, generation, fallback, cache, or parallel path, name the approved requirement, reproduced failure, external contract, or reachable risk it serves. Apply the deletion test. If the mechanism only adds concepts while required behavior survives without it, do not build it.

5. Shape execution for throughput

Use direct implementation for tightly coupled work and .agents/skills/decompose-gates for meaningful independent responsibilities. For repeated units with an unproven shared assumption, apply that skill's concurrency ramp: gate only dependent replication, keep independent work moving, and skip the ramp when prior evidence or a deterministic tool already proves the unit shape.

Delegate complete responsibilities rather than tiny edits. A lane owns its discovery, implementation, focused RED/GREEN proof, relevant validation, compact self-review, and concise result. Briefs name the goal, intent, corridor, evidence, dependencies, collision surfaces, completion and negative criteria, validation, permissions, and stop conditions. Do not reserve files or duplicate generic doctrine in every brief.

Use the fastest reliable mechanism for the work:

repository scripts and generators;
compiler/language-server renames;
AST-aware codemods for structural repetition;
bounded structured replacement for uniform text/configuration;
formatters and deterministic validators;
batched retrieval with compact output.

Preview broad transformations, establish their match set, inspect representative and aggregate diffs, and validate omissions plus unintended matches. Do not build tooling when a few direct edits are safer and faster.

6. Resolve uncertainty with evidence

Uncertainty is an investigation task, not a reason to skip in-scope work. Classify the missing answer first: if source, history, a focused prototype, test, schema, log, measurement, runtime state, artifact, or current primary documentation can decide it safely, retrieve that evidence. Ask only for a genuine product, preference, authority, or tradeoff decision evidence cannot settle, unavailable external state, or material expansion/redesign. Continue independent work that cannot prejudge that decision.

7. Implement through a valid test and real path

Use .agents/skills/happier-testing. Production behavior changes require meaningful RED for the intended observable contract, minimal coherent GREEN, then refactoring with tests green.
Mock only genuine system boundaries; keep internal domain behavior real.
Implement through the canonical/public owner boundary and a consumed path, not a dormant horizontal spine.
Use .agents/skills/happier-compatibility for released wire, semantic, persistence, migration, upgrade, coexistence, or rollback seams.
Use relevant UI/design/React/React Native skills for user-facing work under DESIGN.md and package instructions.
Preserve performance, continuity, accessibility, security, privacy, and Windows/Linux/macOS behavior wherever the changed corridor can materially differ.

Classify unexpected failures before changing code: production defect, test drift, harness drift, environment/resource failure, external-contract change, or unrelated failure. A green test is invalid evidence when the harness suppresses errors, mocks away the deciding path, or asserts the defective contract.

8. Validate the outcome, not implementation presence

Run the narrowest deciding GREEN check, then broaden according to reachability, silence of failure, blast radius, and reversibility. Exercise relevant happy, edge, failure, cancellation, recovery, persistence, compatibility, platform, and neighboring-owner behavior without manufacturing Cartesian matrices.

For user-visible or environment-dependent changes, run the composed live browser/device/CLI/API/daemon recipe against the relevant loaded source/build when authorized and available. If that proof cannot run, use IMPLEMENTED_NOT_VERIFIED and name the missing prerequisite; do not substitute more internal checks and claim completion.

Do not guess an expected result that cannot be derived from the user request, approved plan when applicable, current external contract, or observed canonical behavior. Distinguish implementation missing/wrong, implementation present but behavior unverified, evidence unavailable, and expected behavior materially ambiguous.

If a successor-line port is required, source validation alone is not completion. Before closeout, require an evidence-backed destination disposition for every source intent and deciding destination validation for every applicable change. An unavailable destination blocks only the port portion and must be reported explicitly; it does not invalidate completed source analysis or source validation.

9. Review and correct at useful boundaries

Continuously perform compact author self-review without creating a separate review program. Inspect bypasses, split-brains, neighboring cases, environment gaps, and complexity introduced by the change; run .agents/skills/attack-conclusion before a non-trivial handoff.

Use .agents/skills/happier-review for an explicit review request, a substantial integrated boundary, a risk-selected independent gate, or a review-plus-fix loop. Review findings are candidate claims. Re-derive accepted findings, separate defect from proposed mechanism, and cluster fixes by originating cause and canonical owner.

After a fix batch, recheck the accepted-finding delta and affected corridor. Repeat a full review only when the contract, architecture, scope, boundary, or risk materially changed.

10. Close from evidence

For work linked to a GitHub issue, keep the source correction, commit relationship, public response, release availability, and issue closure as distinct facts:

preserve unrelated work and form one coherent correction per commit; one correction may resolve several issues, while one issue may legitimately require several commits;
select exact paths or hunks when committing in a dirty worktree, and keep the defining regression test with the behavior it proves;
use the checkout's existing current-user Git identity for ordinary commits; never replace it with the bot or a contributor identity, and keep contributor credit in commit-specific verified trailers;
use Refs #N for partial fixes, mitigations, release-gated corrections, or work that should leave the issue open;
use Fixes #N only when integration into the default branch satisfies the issue's actual closure gate; because dev is the default branch, a closing keyword can close an issue before preview or stable users receive the correction;
inspect the issue author and comments for material contributions embodied in the correction. A supplied causal insight, decisive reproduction, design, patch, or substantially adopted solution earns a verified Co-authored-by: Name <email> trailer on each commit that incorporates it; a routine report, requested log, confirmation, or generic suggestion does not automatically earn code co-authorship;
resolve the contributor's GitHub-associated email or GitHub-provided noreply identity before committing. Never put an @handle in the trailer, guess or expose a private email, silently drop an unresolved attribution candidate, or let attribution change the independently selected Refs/Fixes relationship;
after implementation, propose a Conventional Commit message and a detailed GitHub response grounded in the verified cause, owner-level correction, choices, tests, public provenance, current stage, and reporter-channel follow-up;
do not apply labels, post comments, or close the issue without the exact or bounded standing mutation authority required by .agents/skills/happier-github-ops.

When the complete correction is integrated and verified on canonical dev, include stage:source for every affected open issue in the next authorized GitHub mutation. Omit it only when the issue already has the same or a higher verified stage, or the evidence-backed disposition establishes that no correction exists to release; state that reason explicitly. Under exact authorization, include it in the preview; under a standing grant that covers issue labels, apply and report it without another prompt. If mutation authority is absent, report the pending proposal instead of applying it or silently leaving the issue outside the release queue. Local 0.2 work, an open pull request, or an unmerged commit does not qualify. Normal release workflows advance later labels; implementation agents do not predict or pre-advance channels.

Keep human handoff separate from availability. After a source correction, choose among three states: retain needs:maintainer only when a named project-side review, diagnosis, implementation, or engineering correction remains; use needs:reporter when an authorized public request makes external confirmation or diagnostics the next decision-material human input, even if the reporter must first wait for a named release stage; or clear both when only merge/release progression, promotion, publication, release-owned certification, backlog scheduling, or eventual closure remains. stage:* records the release prerequisite. Do not use needs:maintainer as a generic release-queue marker, and do not use hidden saved-reply directives to manufacture mutation authority.

Use these outcomes:

VERIFIED_COMPLETE: the real owner, wiring, removals, tests, broader checks, and required live evidence establish the complete outcome;
IMPLEMENTED_NOT_VERIFIED: implementation is present but a decision-material behavior surface was not exercised;
PARTIAL: authorized work remains;
BLOCKED: a named prerequisite, authority, or external state prevents safe completion.

Do not claim completion because files exist, code compiles, agents stopped, checkboxes changed, or a subset of tests passed. Report through .agents/skills/handoff-report: outcome first, checks actually run, failed/skipped evidence, and residual risk.

When it activates
