Automate me

A guided flow for turning the user's working conventions into a skill agents will follow. The output is one -mode skill tailored to them (e.g. jay-mode, priya-mode).

This skill orchestrates three others: an inline mining pass (see step 1), the plugin-dev:skill-development skill (authoring), and the unslop skill (prose discipline). It sequences them; it doesn't replace them.

Platform note. On Codex, the Claude tool names, claude-* slugs, and Claude built-in skills named below (including plugin-dev:skill-development) are Claude defaults. Resolve them via codex-tools.md.

Flow

0. Check for an existing skill

Look recursively for .claude/skills/**/*-mode/SKILL.md and ~/.claude/skills/*-mode/SKILL.md matching the user's handle. Mode skills can live in a personal category directory (.claude/skills/<handle>/), not only at the top level. If one exists, confirm intent with AskUserQuestion (unless they already said "update my skill" or similar):

• Update the existing skill (default for repeat runs)
• Start fresh (rare; ask why before doing it)

Update mode changes the rest of the flow:

• Step 1 mines only history since the skill was last edited (git log -1 --format=%cI <path>).
• Step 2 asks what's changed or missing, not what to capture from zero.
• Step 4 edits the existing file in place. Preserve sections the user hasn't contradicted; revise ones with new evidence; add new sections only for genuinely new rules.

1. Mine their history

Locate the active workspace's transcripts before fanning out. Claude Code stores them at ~/.claude/projects/<encoded-cwd>/*.jsonl, where <encoded-cwd> is the workspace's working directory with / → -. Use only that path. Don't glob across ~/.claude/projects/. That crosses workspace boundaries and reads private chats from unrelated projects.

Survey recent agent conversations within that scope for recurring patterns. Run multiple parallel subagents across slices of history (e.g. last 2-4 weeks, split into 3 slices so each has enough material). Each slice mining subagent reads transcripts from the workspace-scoped path the parent provides, looks for the signals below, and returns a short structured list of patterns it saw with evidence pointers. Default signals worth hunting:

• Response preferences (length, tone, format, "dumb it down" corrections)
• Delegation habits (subagents, models, specialized workflows, parallelism)
• Verification posture (what "done" means; unit tests vs live repro; reviewers)
• Code and prose discipline (style, principles cited, lint/format tools)
• Process conventions (worktrees, commits, PRs, review/merge tooling)
• Meta preferences (fixing skills mid-task, proposing new ones)

Cross-check across slices before elevating a signal. Patterns seen in 2+ slices are high-confidence; lone signals are weak and usually get dropped.

2. Ask the user directly

Mining misses intent that hasn't come up yet. Use the AskUserQuestion tool (structured multi-choice) rather than asking the user to type from scratch. Lower cognitive load, higher hit rate.

Shape: one or two questions with 4-6 options each, allow_multiple: true for category questions. Start broad ("Which areas matter most?"), then follow up on selected areas with specific options. After the structured rounds, one free-form chat question catches anything the options missed.

Don't dump 20 questions. Two structured rounds plus one open question is usually enough.

3. Cluster findings

Group the combined signals into sections. Common ones (use only what applies):

• Response style: length, tone, format.
• Autonomy: how much to do without asking; MCP tool use.
• Understand first: which skills to reach for when scoping or investigating a change.
• Subagents: default, parallelism, model-to-task, specialized workflows.
• Prose / code discipline: principles, lint tools, style guides.
• Review and verify: repro posture, verification skills, live-testing tools.
• Process: git worktrees, commits, PRs, review/merge tooling.
• Skills: skill-authoring habits, fix-the-skill-first, proposing new skills.

The engineer-mode skill shows the shape. Read it for granularity. Don't copy its content; the user's rules are not the same as engineer-mode's.

4. Draft the skill

Use the plugin-dev:skill-development skill to author the skill. Placement:

• Path: preserve an existing mode skill's category. For a new mode, use .claude/skills/<handle>/<handle>-mode/SKILL.md when the repo has an established personal category for that handle; otherwise default to .claude/skills/<handle>-mode/SKILL.md in the project (or ~/.claude/skills/<handle>-mode/ if the user prefers a personal skill).
• Handle: the user's first name or chosen identifier.
• Frontmatter description: trigger on their name + /<handle>-mode + "work in their style", not on generic keywords like "write code" or "review PR".
• Frontmatter formatting: follow plugin-dev:skill-development's YAML rules. Keep description as one YAML scalar; quote it or use description: >- with indented continuation lines when punctuation or wrapping requires it.
• Frontmatter disable-model-invocation: true by default. Mode skills are heavy and opinionated; they should only apply when the user explicitly invokes them (by name or slash command), not auto-trigger on description matching. Opt out only if the user explicitly wants their mode to apply on every turn.

5. Iterate on prose

Apply the unslop skill and plugin-dev:skill-development's writing guidelines to every line. Both apply to any agent-read prose, not just skills.

Show the draft to the user and take feedback. Expect multiple iterations. Cut ruthlessly; a mode skill is not a manual.

6. Land it

Work in a worktree off main. Commit and open a PR so the user can review it. Don't push to main directly.

Guardrails

• Don't overfit to one conversation. A preference stated once and contradicted another time is noise. Require multiple instances before codifying it.
• Don't be clever. Restating other skills' contents, inventing metaphors, or writing "poetic" prose for an agent reader is cost without benefit. Keep it operational.
• Reference, don't inline. Other skills the user relies on should appear as path references, not pasted excerpts. Same for any principle docs they maintain elsewhere.
• Keep sections minimal. Only add a section if the user has a specific, non-default rule there. "Communicate clearly" is not a section. "Short paragraphs. Tables when comparing options. Bullets only when items are genuinely parallel." is.
• Name conventions generic. Use "the user" or "the human" in imperatives, not the author's first name. Others may read or adopt the skill.
• Don't force symmetry. If a user has no process rules worth writing down, skip the Process section entirely. Sparse is fine; bloated is not.

Evaluation

A -mode skill is subjective output. A plugin-dev:skill-development-style test/iterate benchmark loop isn't useful here. Vibe-check with the user: does it read like them? Did it miss anything? Then ship.

Run a description-optimization loop only if the skill's trigger accuracy turns out to be a problem in practice.

When not to use

• User wants a task-specific skill (not working conventions): plugin-dev:skill-development alone, no mining required.
• User wants to capture one narrow workflow (e.g. "how I write commit messages"): that's a regular skill, not a mode skill.

Reference files

• The engineer-mode skill: example of the output shape.
• The unslop skill: prose discipline for every line.
• the plugin-dev:skill-development skill: skill authoring process and writing guidelines.
