Use this skill whenever the user says commit it, commit this, commit changes, commit, or any phrase requesting a git commit. Also trigger when the user asks to save my changes or push this in a git context."

+# Commit It
+
+Automates the full commit workflow: inspect changes, format code, stage files, generate a Conventional Commit message, and commit. Designed to be fast — the user said "commit it" because they want it done, not to answer a bunch of questions.
+
+## Instructions
+
+### 1. Check Git State
+
+First, make sure the repo is in a clean state for committing:
+
+```bash
+git status
+```
+
+If the repo is in the middle of a merge, rebase, or cherry-pick, inform the user and stop. These need to be resolved manually.
+
+If there are no changes (nothing modified, nothing untracked), tell the user "Nothing to commit" and stop.
+
+### 2. Inspect Changes
+
+Run in parallel to understand what changed:
+- `git diff` (unstaged changes to tracked files)
+- `git diff --cached` (already staged changes)
+- `git status --porcelain` (all changes including untracked files — look for `??` lines)
+- `git log --oneline -5` (recent commits for style reference)
+
+**Important:** Untracked files (`??` in `git status`) are often newly created files from the current session. They MUST be included in the commit alongside modified files.
+
+### 3. Pre-Commit Formatting
+
+Only run formatters relevant to the files that actually changed. Collect the full list of files to commit:
+
+```bash
+# Modified tracked files (staged + unstaged)
+git diff --name-only
+git diff --name-only --cached
+# Untracked files (newly created)
+git ls-files --others --exclude-standard
+```
+
+**If any `.sol` files under `contracts/tests/` changed:**
+```bash
+forge fmt <those-files>
+```
+
+**If any `.sol` files NOT under `contracts/tests/` changed:**
+```bash
+npx prettier --write --plugin=prettier-plugin-solidity <those-files>
+```
+
+**If any files under `src/js/` or JS config files changed:**
+```bash
+yarn lint --fix
+yarn prettier --write <changed-js-files>
+```
+
+Do NOT run formatters on the entire project — only pass the specific changed files.
+
+If formatting fails and can't auto-fix, tell the user what's wrong and ask whether to proceed anyway.
+
+### 4. Stage Files
+
+Stage ALL modified and untracked files individually. This includes:
+- Modified tracked files (`M` in git status)
+- Newly created untracked files (`??` in git status)
+
+Do NOT use `git add -A` or `git add .`.
+
+**Skip files that look like secrets:**
+- `.env`, `.env.*` (environment files)
+- Files with `credential` or `secret` in the name
+- `*.pem`, `*.p12`, `*.pfx` (certificates)
+- `*.key` files (private keys — but NOT files that merely contain "key" in the name like `keyManager.sol`)
+
+If any sensitive files are detected, warn the user and list them.
+
+Also re-stage any files that were modified by the formatters in step 3.
+
+### 5. Generate Commit Message
+
+Analyze the staged diff (`git diff --cached`) and generate a Conventional Commit message.
+
+**Format:** `type(scope): description`
+
+**Types:**
+- `feat` — new feature or capability
+- `fix` — bug fix
+- `refactor` — code restructuring without behavior change
+- `perf` — performance or gas optimization
+- `test` — adding or updating tests
+- `docs` — documentation only
+- `chore` — tooling, config, dependencies, CI
+
+**Scope** — derived from the primary area of change:
+- `lido` / `etherfi` / `ethena` / `origin` — ARM-specific
+- `arm` — core AbstractARM
+- `deploy` — deployment scripts
+- `js` — JavaScript automation/actions
+- `cap` — CapManager
+- `zapper` — Zapper contracts
+- `market` — market adapters (Morpho, Silo)
+- `pendle` — Pendle integration
+- `sonic` — Sonic chain specific
+- `skill` — Claude Code skills
+
+If changes span multiple areas, use the most significant one. For mixed changes, omit the scope.
+
+**Description:** imperative mood, lowercase, no period. Under 72 characters. Focus on "why" not "what".
+
+For substantial changes, add a body with bullet points after a blank line.
+
+**Examples:**
+```
+feat(ethena): add parallel cooldown support for sUSDe unstaking
+fix(arm): prevent rounding error in withdrawal queue processing
+refactor(deploy): extract shared deployment logic into DeployManager
+test(lido): add fork tests for stETH discount scenarios
+chore: update soldeer dependencies
+perf(arm): reduce SLOAD count in swap path
+docs(skill): add commit automation skill
+```
+
+### 6. Commit
+
+**CRITICAL: Always run `git commit` in this step. Never stop after staging — the user said "commit it" and expects the commit to be created. Do NOT ask questions before committing.**
+
+Check the user's original message for preferences:
+- **Co-Authored-By**: Look for "with co-author", "add trailer", "include co-author", etc. Default: no trailer.
+- **Push**: Look for "and push", "push it", "push too", etc. Default: don't push.
+
+Create the commit using a HEREDOC:
+
+**Without trailer (default):**
+```bash
+git commit -m "$(cat <<'EOF'
+type(scope): description
+EOF
+)"
+```
+
+**With trailer:**
+```bash
+git commit -m "$(cat <<'EOF'
+type(scope): description
+
+Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
+EOF
+)"
+```
+
+Run `git status` after to verify the commit succeeded.
+
+Then present the result:
+
+> Committed `<short-hash>`: `type(scope): description`
+
+### 7. Push (Only If Requested)
+
+If the user asked to push (either in the original message or after the commit), use `git push` (or `git push -u origin <branch>` if no upstream is set).
+
+If they didn't ask to push, don't ask — the commit is done.
+
+## Safety Rules
+
+- NEVER amend existing commits unless explicitly asked
+- NEVER force push
+- NEVER skip hooks (no `--no-verify`)
+- If a pre-commit hook fails, fix the issue, re-stage, and create a NEW commit (do not amend)
+- If there are no changes to commit, inform the user and stop
