♻️ Move skills and plans to .agents for cross-tool use

.agents is the shared home that opencode, Claude Code (through the
.claude/skills symlink) and Codex all read, so the skills and the
saved plans now live there instead of .opencode:

- .opencode/skills moved to .agents/skills (24 files, no content
  changes).
- .opencode/plans moved to .agents/plans; the .gitignore entry
  follows, so plans stay untracked.
- .claude/skills symlink retargeted to ../.agents/skills.
- planner, make-a-plan and review-plan updated to the new plans path;
  new .agents/README.md documents every skill with when-to-use
  examples and links to each SKILL.md.
- workflow/creating-issues memory: create-issue path updated.

opencode discovers .agents/skills natively, so .opencode needs no
reciprocal link.

+# Agent skills
+
+This folder is the single home for the skills our coding agents use.
+Each skill is a folder with a `SKILL.md` inside — a short instruction
+manual that an agent loads only when it needs it.
+
+One copy serves every tool:
+
+- **opencode** reads this folder directly.
+- **Claude Code** reads it through the `.claude/skills` symlink.
+- **Codex** reads it directly.
+
+To change how the agents behave, edit the `SKILL.md` here. There is no
+second copy to keep in sync.
+
+## How the skills are organized
+
+**Flows** are the six skills you invoke by name. Each one covers one step
+in the life of a change: plan it, review the plan, implement it, review
+the code, open the pull request.
+
+**References** hold the quality standards. A flow's reviewer loads them;
+you rarely touch them directly.
+
+**Procedures** define how one concrete step is done — a plan document, an
+issue, a commit. Flows call them, but they also work on their own.
+
+**Utilities** are small helpers for everyday work: search, file lookup,
+JSON, REPL access, and so on.
+
+## Flows
+
+| Skill | What it does | When you would say |
+|---|---|---|
+| [`make-a-plan`](skills/make-a-plan/SKILL.md) | Researches the task, writes an implementation plan, asks you the open questions in plain language, and saves the plan to `.agents/plans/`. | "make a plan for the token refresh bug" |
+| [`review-plan`](skills/review-plan/SKILL.md) | Evaluates a plan before anyone writes code: completeness, ordering, risks. Approves it or asks for changes. | "review this plan before we start" |
+| [`implement-plan`](skills/implement-plan/SKILL.md) | Executes a ready plan and ends with one commit. Starting from a base branch (`main`, `develop`, `staging`), it first creates a GitHub issue and a matching `issue-NNNN` branch; already on a feature branch, it continues there without creating anything. | "implement the plan" |
+| [`review-code`](skills/review-code/SKILL.md) | Reviews a diff, branch, or PR and returns findings ranked by impact. | "review my changes before I push" |
+| [`create-pr`](skills/create-pr/SKILL.md) | Opens a pull request for the current branch — with checks on base branch, commits, issue, and push state — or updates an existing PR's title and description. | "open a PR for this branch" |
+| [`resolve-git-conflicts`](skills/resolve-git-conflicts/SKILL.md) | Untangles merge or rebase conflicts: explains both sides, proposes a resolution, applies it after you approve. Never runs `git rebase --continue`. | "resolve these conflicts" |
+
+## References
+
+| Skill | What it holds |
+|---|---|
+| [`plan-review-criteria`](skills/plan-review-criteria/SKILL.md) | The plan review rubric: six axes, severity levels, approval standard, output format. The `review-plan` reviewer loads it. |
+| [`code-review-criteria`](skills/code-review-criteria/SKILL.md) | The code review rubric: five axes, core principles (DRY, KISS, YAGNI), severity format, verdict. The `review-code` reviewer loads it. |
+
+## Procedures
+
+| Skill | What it does |
+|---|---|
+| [`planner`](skills/planner/SKILL.md) | The spec of a good plan: context, architecture decisions, tasks with acceptance criteria, checkpoints. Used by `make-a-plan`. |
+| [`create-issue`](skills/create-issue/SKILL.md) | Creates a GitHub issue that follows Penpot conventions. Used by `implement-plan`; also works on its own. |
+| [`create-commit`](skills/create-commit/SKILL.md) | Makes a commit the Penpot way: emoji subject, clear body, `AI-assisted-by` trailer. Used by `implement-plan`; also works alone when you say "commit this". |
+
+## Utilities
+
+| Skill | What it does |
+|---|---|
+| [`bat-cat`](skills/bat-cat/SKILL.md) | Read files in the terminal with syntax highlighting and line numbers. |
+| [`fd-find`](skills/fd-find/SKILL.md) | Find files by name or pattern, respecting `.gitignore`. |
+| [`ripgrep`](skills/ripgrep/SKILL.md) | Fast content search with regular expressions. |
+| [`jq-json-processor`](skills/jq-json-processor/SKILL.md) | Slice, filter, and reshape JSON output. |
+| [`nrepl-eval`](skills/nrepl-eval/SKILL.md) | Run Clojure or ClojureScript code in the live REPL sessions (backend and frontend). |
+| [`taiga`](skills/taiga/SKILL.md) | Look up Penpot issues, user stories, and tasks in Taiga. |
+| [`testing`](skills/testing/SKILL.md) | The repo's testing rules and TDD workflow, loaded before writing tests. |
+| [`security-and-hardening`](skills/security-and-hardening/SKILL.md) | Security checks for code that handles user input, auth, or external services. |
+| [`ste`](skills/ste/SKILL.md) | Rewrites prose in Simplified Technical English. Loads only when you name it. |
+| [`refine-prompt`](skills/refine-prompt/SKILL.md) | Rewrites a rough prompt into a clearer one. Never runs the prompt. |
+| [`update-changelog`](skills/update-changelog/SKILL.md) | Regenerates `CHANGES.md` from a GitHub milestone. |
+
+## A typical round
+
+1. `/make-a-plan` — you get a plan and a saved file in `.agents/plans/`.
+2. `/review-plan` — a second opinion; approve or request changes.
+3. `/implement-plan` — the code gets written and committed. Starting from a base branch, it also opens the GitHub issue and the `issue-NNNN` branch; the plans that follow continue on that same branch.
+4. `/review-code` — a reviewer checks the commit.
+5. `/create-pr` — the branch goes up as a pull request.
+
+Every step also works on its own, and you can always say what you want
+in plain words — the agents pick the right skill from what you say.
+
+## Adding or changing a skill
+
+Create a folder here with a `SKILL.md` inside. The file needs `name` and
+`description` in its frontmatter, and a clear "When to use" section so
+agents know when to reach for it. Keep one job per skill, and keep the
+two families apart: flows are named with a verb first; reference skills
+end in `-criteria`.
