Connor Griffin's agent skills

A portable skill pack for coding agents. Skills live under skills/ and work with clients that support the Agent Skills format. Each skill files under one of two categories: drivers (multi-phase procedures chosen deliberately, which call other skills by name) and tools (skills that do one job themselves). Some skills compose: ticket calls plan-review and code-review at its gates.

Included skills

Drivers

Skill	Purpose	Extra requirement
implement	Routes tracked work through ticket; gives an explicit isolated-worktree intake for an untracked PRD	ticket and code-review from this pack
openspec-adopt	Initialize the OpenSpec v1 layout and baseline specs describing the system today, delivered as a documentation-only PR	GitHub CLI; global @fission-ai/[email protected]
ui-craft	Design through eight gated stages, structure first and reviewed at component grain, ending in a one-page lock in the repo; build or revise in a separate ticket; review rendered UI (stages: lock reference)	Claude Code's Design and Design System artifact types, or plain artifacts, for canvases; Claude in Chrome or the built-in browser for rendered checks; subagent support for the cold critique
ticket	Drive one tracked ticket through four verbs, one artifact each with a human gate between: triage resolves open questions and locks a work order on the ticket, start builds it to an open pull request, revise actions one review round, finalize closes it after a human merges and records what it cost. Agents never merge	GitHub CLI for the bundled issues binding, one binding page per other tracker; composes with plan-review, code-review

Tools

Skill	Purpose	Extra requirement
ci-design	Vocabulary and principles for well-designed CI	—
code-review	Review changes since a fixed point on two axes, Standards and Spec, each returning a verdict per enumerated item so a round terminates	Parallel-agent support recommended; GitHub CLI to fetch an originating issue; see docs/review-round-mining.md for the mined evidence behind the fix protocol and the round cap
codebase-design	Shared vocabulary for designing deep modules	—
domain-modeling	Build and sharpen a project's domain model	—
handoff	Produce a decision-safe handoff for a fresh agent	—
plan-review	Adversarially review a plan or work order with cold agents before building	Parallel-agent support recommended; the round-count evidence behind its rules is in docs/review-round-mining.md

Install

Install one skill with the standard skills CLI:

npx skills add ConnorGriffin/skills --skill ui-craft

Install several together:

npx skills add ConnorGriffin/skills \
  --skill ticket \
  --skill plan-review \
  --skill code-review

Install every skill:

npx skills add ConnorGriffin/skills --all

The CLI prompts for the target agents and whether to install per-project or globally. Review skill instructions and scripts before running them; several skills intentionally start processes or modify repositories.

Optional integrations

Optional integrations are enhancements, not hidden runtime requirements. Both ship in this pack and are optional because a partial install can leave them out:

• codebase-design: ships in this pack; referenced by tdd; helps shape non-trivial module interfaces. Without it, keep the shipping module shape and preserve locality.
• domain-modeling: ships in this pack; referenced by codebase-design; maintains a project's domain vocabulary. Without it, ground terms in the repo's own docs.

Attribution

The implement, tdd, and prototype skills are adopted from — and code-review is derived from — Matt Pocock's skills repository (MIT, copyright (c) 2026 Matt Pocock), lightly edited here to be self-contained. See LICENSE and NOTICE.

Output style

output-styles/say-less.md is a Claude Code output style: it replaces the built-in coding instructions so every reply leads with the outcome and stops there. The say-less skill is the full ruleset for documents; the style is the always-on subset.

Same task, same model, style the only difference. Neither reply is truncated:

Both arms found the same three defects. Full text of every arm: examples/transcripts/.

Across 120 headless runs on a 10-question set with an executed answer key:

model	median output tokens, default	say-less	outcomes correct, default	say-less
claude-opus-5	348	164	20/20	10/10
claude-sonnet-5	436	164	115/120	38/40
claude-fable-5	456	178	20/20	10/10

Half to two thirds of the reading, no correctness cost on opus or fable. Sonnet keeps one residual failure worth knowing about before you install it, and compression drops caveats a longer reply would have kept: both are measured, with their method and the counterexamples, in docs/before-after.md.

Activate it by setting "outputStyle": "say-less" in ~/.claude/settings.json after linking the file into ~/.claude/output-styles/, or run /output-style say-less in an interactive session. New sessions pick it up; the one you are in does not.

Shared profile

profile/ holds a machine-agnostic global-instructions layer (communication rules, working preferences, an engineering charter) meant to be @-imported from a local checkout of this repo into each machine's own CLAUDE.md/AGENTS.md, with machine-specific overlays staying private. See profile/README.md for setup.

Development

Run the repository checks with:

python3 scripts/validate.py

Contributions require a Signed-off-by trailer under the Developer Certificate of Origin.
