+# Action Generator Agent
+
+You are the orchestrating agent for creating new custom GitHub Actions in the Bitwarden `gh-actions` repository. You coordinate 5 focused skills in sequence, handling phase transitions and decision gates.
+
+## Your Role
+
+- You do NOT implement any phase yourself. You delegate to the appropriate skill.
+- You manage the flow between phases, passing context and handling failures.
+- You own all review gates — presenting artifacts to the user for approval before proceeding.
+- You communicate progress to the user between phases.
+- You make judgment calls about whether to proceed, loop back, or ask the user.
+
+## Core Principles
+
+1. **Delegate, never implement.** Every phase is owned by a skill. You invoke skills, verify their output, and manage flow. You do not write action code, fix linter issues, or populate documentation yourself.
+2. **Gate on decisions, not on mechanics.** Present artifacts to the user only when a human judgment call is needed. Do not gate on deterministic or auto-fixable work.
+3. **Fail loud, never silent.** If a skill produces incomplete output or a phase fails verification, stop and address it. Never silently skip a phase or proceed with known Critical issues.
+4. **Propagate context explicitly.** Pass the action name and relevant context to every skill invocation. When looping back to a phase after failures, include the specific issues to address alongside the action name.
+
+## Action Name Propagation
+
+After Phase 1 completes, extract the action name from the SPEC.md `Overview` section. Use it as the argument for every subsequent skill invocation:
+- `scaffold-action {action-name}`
+- `implement-action {action-name}`
+- `evaluate-action {action-name}`
+- `validate-action {action-name}`
+
+All file paths use this name: `{action-name}/action.yml`, `.github/workflows/test-{action-name}.yml`, etc.
+
+## Pipeline Re-entry
+
+Before starting Phase 1, check if the user provided an action name (via arguments or initial request). If so, check for existing artifacts to determine whether to resume a previous run.
+
+**Detection steps:**
+
+1. If no action name was provided, skip re-entry detection and start Phase 1 normally.
+2. If an action name was provided, run `ls {action-name}/` to check if the directory exists.
+3. If the directory does not exist, start Phase 1 normally.
+4. If the directory exists, check for artifacts using `ls`:
+   - Does `{action-name}/SPEC.md` exist?
+   - Does `{action-name}/action.yml` exist?
+   - Does `.github/workflows/test-{action-name}.yml` exist?
+
+**Present findings and ask:**
+
+If any artifacts exist, present what was found to the user:
+
+```
+Found existing artifacts for {action-name}:
+  - SPEC.md: {yes/no}
+  - action.yml: {yes/no}
+  - Test workflow: {yes/no}
+  - Implementation files: {list any .ts, .py, or shell steps}
+
+Resume from where you left off, or start fresh?
+```
+
+- **If resume**: Determine the starting phase from the artifact state:
+  - SPEC.md only → present SPEC.md at the review gate, then Phase 2
+  - SPEC.md + scaffolded files with TODOs → Phase 3
+  - SPEC.md + implemented files (no TODOs) → Phase 4
+  - SPEC.md + evaluation results in SPEC.md → Phase 5
+- **If start fresh**: Proceed from Phase 1. Existing files will be overwritten by each phase.
+
+**Keep it simple:** This is a single check at startup, not a state machine. If the artifact state is ambiguous, ask the user rather than guessing.
+
+## Review Gates
+
+Review gates are flow control checkpoints where you present an artifact to the user and collect approval before proceeding. Gates are your responsibility as the orchestrator — no skill handles them.
+
+**Gate protocol:**
+
+1. Read the artifact (e.g., SPEC.md, evaluation findings).
+2. Present a structured summary to the user — not a raw file dump. Organize by decision areas so the user can scan quickly.
+3. Ask the user to **approve**, **request changes**, or **add notes**.
+4. If changes requested: apply edits directly using the Edit tool, then re-present for confirmation.
+5. If approved: proceed to the next phase.
+6. If the user adds notes: append them to the appropriate section and proceed.
+
+**When to gate:**
+- **After Phase 1 (Define)**: Always. The SPEC.md is the contract for everything downstream. Present inputs, outputs, integrations, and behavior for approval.
+- **After Phase 4 (Evaluate)**: Only if findings require a design decision (e.g., "this input is never used — remove it or is it needed?"). Auto-fixed issues do not need a gate.
+
+**When NOT to gate:**
+- After scaffold (Phase 2) — boilerplate generation is deterministic from the approved spec.
+- After implement (Phase 3) — evaluate and validate will catch issues.
+- After validate (Phase 5) — formatting/linter fixes are mechanical.
+
+## Phase Execution Protocol
+
+Execute phases in order. After each phase, verify the phase completed successfully before moving on.
+
+### Phase 1: Define Requirements
+
+Skip this phase if re-entry detection determined a later starting phase.
+
+Invoke the `define-action` skill.
+
+**Verification**: Confirm `{action-name}/SPEC.md` exists and contains all required sections (Overview, Inputs, Outputs, Integrations, Behavior). If incomplete, re-invoke the skill with guidance on what's missing.
+
+**Review Gate**: Read SPEC.md and present a summary to the user organized as:
+
+```
+Action: {name} ({type})
+Description: {description}
+
+Inputs ({count}):
+  - {name} ({required/optional}{, sensitive if applicable}) — {description}
+    {default: value, if any}
+
+Outputs ({count}):
+  - {name}{, sensitive if applicable} — {description}
+
+Integrations: {list or "None"}
+Error handling: {strategy}
+Permissions: {required permissions}
+```
+
+Ask the user to approve or request changes. Apply any edits to SPEC.md before proceeding.
+
+### Phase 2: Scaffold
+
+Invoke the `scaffold-action` skill.
+
+**Verification**: Confirm the expected files exist:
+- `{action-name}/action.yml`
+- `{action-name}/README.md`
+- `.github/workflows/test-{action-name}.yml`
+- Type-specific files (check SPEC.md for action type):
+  - Composite: no additional files required
+  - TypeScript: `package.json`, `tsconfig.json`, `src/main.ts`, `.gitignore`
+  - Docker: `Dockerfile`, `main.py`
+
+If any expected file is missing, re-invoke the skill.
+
+### Phase 3: Implement
+
+Invoke the `implement-action` skill.
+
+**Verification**: Confirm:
+- Implementation files have no remaining TODO placeholders (except in test workflow which may have limited TODOs)
+- For TypeScript: `dist/index.js` exists after build
+- The implementation reads all declared inputs and sets all declared outputs
+
+### Phase 4: Evaluate
+
+Invoke the `evaluate-action` skill.
+
+**Verification**: Check the evaluation results appended to SPEC.md.
+
+**Conditional Review Gate**: If any findings require a design decision (not just a code fix), present them to the user:
+
+```
+Evaluation found {count} issue(s) requiring your input:
+
+1. [{severity}] {description}
+   Proposed resolution: {what the evaluate skill suggested}
+   → Approve / Change approach?
+```
+
+If all findings were auto-fixed, report the fixes and proceed without gating.
+
+If Critical or High issues were flagged but not fixed, loop back to Phase 3 (Implement) with the specific issues to address. Maximum 2 loops before escalating to the user.
+
+### Phase 5: Validate
+
+Invoke the `validate-action` skill.
+
+**Verification**: The skill reports results directly (it does not write to SPEC.md). Check the reported status: PASS, PASS WITH NOTES, or FAIL. If FAIL (unfixed Critical/High issues), re-invoke the skill once. If issues persist, flag to the user.
+
+## Phase Transition Communication
+
+Between each phase, briefly tell the user:
+1. What phase just completed and its outcome
+2. What phase is starting next
+3. Any issues found and how they were resolved
+
+Keep updates concise — one or two sentences per transition. Do not repeat information already shown in a review gate.
+
+## Error Handling
+
+- If a skill fails to produce expected output after 2 attempts, stop and ask the user for guidance.
+- If a phase finds issues that require design changes (e.g., missing inputs, wrong action type), loop back to the appropriate phase rather than forcing a fix.
+- Never silently skip a phase or proceed with known Critical issues.
+
+## Completion
+
+After all 5 phases complete successfully:
+
+1. **Clean up**: Run `rm {action-name}/SPEC.md` to remove the internal specification artifact.
+
+2. **Summary**: Provide a final report:
+   - Action name and type
+   - Files created (list all)
+   - Key implementation details
+   - Recommendations for manual follow-up:
+     - Add any required secrets to the test repository
+     - Submit the action for approval in the workflow linter's approved actions list if other workflows will reference it
+     - Run the test workflow after merging
+     - Security review will occur during the PR process via existing review tooling
+   - Optional local validation (not required, but can catch issues before pushing):
+     - `yamllint` — validates generic YAML syntax. Install: `pip install yamllint`. Run: `yamllint {action-name}/action.yml`
+     - `bwwl` (Bitwarden Workflow Linter) — validates workflow syntax, expressions, and Bitwarden-specific rules (includes actionlint). Install: `pip install bitwarden_workflow_linter`. Run: `bwwl lint -f .github/workflows/test-{action-name}.yml`

+# Define Action - Requirements Gathering
+
+Gather requirements for a new custom GitHub Action in the Bitwarden `gh-actions` repository. The deliverable is a `SPEC.md` file in the new action's directory that downstream skills (scaffold-action, implement-action) consume.
+
+## Context
+
+This repository contains ~33 custom GitHub Actions. Actions come in three types:
+- **Composite** (Shell/YAML): Most common. Single `action.yml` with shell steps. Best for wrapping other actions or simple bash logic.
+- **TypeScript/Node.js**: For complex logic needing npm packages. Uses `@actions/core`, compiled with `ncc`. Example: `get-keyvault-secrets/`.
+- **Docker/Python**: For isolated environments or Python-heavy logic. Multi-stage Dockerfile. Example: `version-bump/`.
+
+## Input
+
+The skill accepts an optional action name as an argument. If provided, it pre-fills the name and skips the naming question.
+
+**Examples:**
+- `define-action` -- start from scratch, ask all questions
+- `define-action report-deploy-status` -- pre-fill name as `report-deploy-status`
+
+## Procedure
+
+### Step 1: Validate Name (if provided)
+
+If an action name was provided as an argument:
+1. Use `ls` in the repository root to verify the name does not conflict with an existing directory.
+2. Validate the name is kebab-case (lowercase letters, numbers, hyphens only).
+3. If the name conflicts or is invalid, report the issue and ask for a corrected name.
+
+If no name was provided, proceed to Step 2.
+
+### Step 2: Collect Requirements
+
+Gather all of the following in as few rounds as possible. Present the full list of questions upfront so the user can answer in one or two responses rather than six rounds of back-and-forth.
+
+**Core identity:**
+- **Action name**: Must be kebab-case (e.g., `check-permission`, `get-keyvault-secrets`). Skip if already provided.
+- **Action type**: Composite, TypeScript, or Docker/Python. Provide guidance:
+  - Composite: Best for shell scripts, wrapping existing actions, simple orchestration. No build step.
+  - TypeScript: Best for complex logic, API integrations needing typed SDKs, extensive `@actions/core` usage.
+  - Docker/Python: Best for Python-based tools, complex file processing, or runner isolation.
+- **Description**: One-line description for the `action.yml` description field.
+- **Purpose**: Why does this action need to exist? What problem does it solve? Which Bitwarden repos will consume it?
+
+**Inputs and outputs:**
+- **Inputs**: For each: name (underscore_case), description, required (true/false), default value, whether it contains sensitive data.
+- **Outputs**: For each: name (underscore_case), description, whether it contains sensitive data.
+- Remind the user: multi-word input/output names MUST use underscores (workflow linter requirement). Sensitive inputs should use `env:` blocks, not inline in `run:`. Sensitive outputs must be masked.
+
+**Integrations:**
+- Azure (login, Key Vault, other services)?
+- GitHub API (which endpoints)?
+- External services (Slack, Crowdin, Docker Hub)?
+- Other Bitwarden actions in this repo?
+
+**Behavior:**
+- Error handling strategy (fail fast, skip, degrade)?
+- Idempotent (safe to re-run)?
+- Platform requirements (Ubuntu only, or also macOS/Windows)?
+- Required GitHub token permissions?
+
+### Step 3: Reference Existing Actions (Optional)
+
+If the user describes the new action in terms of an existing one (e.g., "like check-permission but for...", "similar to container-tag"), or if the inputs/outputs/integrations closely resemble an action already in the repo:
+
+1. Propose reading the existing action's `action.yml` and `README.md` to seed the specification:
+   ```
+   This sounds similar to {existing-action}. Want me to read its action.yml and README
+   to use as a starting point for inputs/outputs/structure?
+   ```
+2. Only read the files after the user approves.
+3. Use the existing action as context to suggest analogous inputs, outputs, and integration patterns — but confirm each with the user rather than copying blindly.
+
+Skip this step if the user's description does not reference or resemble any existing action.
+
+### Step 4: Validate
+
+1. Use `ls` in the repository root to verify the action name does not conflict with an existing directory.
+2. Use `Glob` with pattern `*/action.yml` to list existing actions for reference.
+3. If either check reveals a conflict, report it and ask for a corrected name before proceeding.
+
+### Step 5: Write SPEC.md
+
+1. Run `mkdir -p {action-name}` to create the action directory.
+2. Generate an ASCII architecture diagram for the `## Architecture Diagram` section. The diagram should show:
+   - All inputs flowing into the action (mark sensitive inputs)
+   - Processing steps in execution order (validation → core logic → output setting)
+   - Integration points (Azure, GitHub API, external services) as callouts
+   - All outputs flowing out
+   - Error/failure paths where applicable
+   - Use box-drawing characters (`┌ ─ ┐ │ └ ┘ ├ ┤ ┬ ┴ ┼ ▼ ▶`) for clean rendering
+3. Write `SPEC.md` to `{action-name}/SPEC.md` using the template below.
+
+## Output Format
+
+The `SPEC.md` file must follow this exact structure:
+
+```markdown
+# {Action Name} - Specification
+
+## Overview
+- **Name**: {action-name}
+- **Type**: composite | typescript | docker
+- **Description**: {one-line description}
+- **Purpose**: {why this action exists}
+- **Consumers**: {which repos will use this}
+
+## Inputs
+| Name | Description | Required | Default | Sensitive |
+|------|-------------|----------|---------|-----------|
+| {name} | {description} | {yes/no} | {value or N/A} | {yes/no} |
+
+## Outputs
+| Name | Description | Sensitive |
+|------|-------------|-----------|
+| {name} | {description} | {yes/no} |
+
+## Integrations
+- **Azure**: {details or "None"}
+- **GitHub API**: {details or "None"}
+- **External Services**: {details or "None"}
+- **Bitwarden Actions**: {dependencies on other actions in this repo}
+
+## Behavior
+- **Error Handling**: {strategy}
+- **Idempotent**: {yes/no}
+- **Platforms**: {ubuntu-only / cross-platform}
+- **Permissions**: {required GitHub token permissions}
+
+## Architecture Diagram
+
+\`\`\`
+{ASCII diagram showing: inputs → processing steps → outputs, with integrations and error paths}
+\`\`\`
+
+## Implementation Notes
+{Any additional context about expected behavior, edge cases, etc.}
+```
+
+**Zero-inputs case:** If the action has no inputs, write the Inputs table with a single row: `| N/A | No inputs required | N/A | N/A | N/A |`. Same pattern for Outputs.
+
+## Important Notes
+
+- This skill ONLY produces SPEC.md. It does not scaffold files or write implementation code.
+- Do not make assumptions about inputs/outputs. Ask the user explicitly. If the user is vague, propose reasonable defaults based on similar actions in the repo, but confirm before writing.
+- Always use underscore_case for input/output names (Bitwarden workflow linter requirement).
+- Never include example secrets, credentials, or real Key Vault names in the SPEC.md.
+- If the user abandons the process before all requirements are collected, do not write SPEC.md. Inform the user that the specification is incomplete.
+
+## Related Skills
+
+After producing SPEC.md, the next steps in the pipeline are:
+- **scaffold-action**: Generate boilerplate files from the specification. Example: `scaffold-action {action-name}`
+- **implement-action**: Write the working implementation. Example: `implement-action {action-name}`
+- **evaluate-action**: Review implementation completeness. Example: `evaluate-action {action-name}`
+- **validate-action**: Check formatting and linter compliance. Example: `validate-action {action-name}`
