-## Contract
-
-**Delegator use only.** This registry is an index, not a summary. Any agent that launches subagents reads it to select relevant skills, then passes exact `SKILL.md` paths for the subagent to read before work.
-
-`SKILL.md` remains the source of truth. Do not inject generated summaries or compact rules by default; pass paths so subagents load the full runtime contract and preserve author intent.

-## Skills
-
-| Skill | Trigger / description | Scope | Path |
-| --- | --- | --- | --- |
-| `auto-commit` | Use when you are making multiple edits or completing significant work in a git repository to automatically create commits | user | `/home/alex/.config/opencode/skills/auto-commit/SKILL.md` |
-| `openspec` | Use OpenSpec as the source of truth for planning, implementation, verification, and archive discipline. | user | `/home/alex/.config/opencode/skills/openspec/SKILL.md` |
-| `openspec-apply-change` | Implement tasks from an OpenSpec change. Use when the user wants to start implementing, continue implementation, or work through tasks. | project | `/home/alex/projects/headquarter/.opencode/skills/openspec-apply-change/SKILL.md` |
-| `openspec-archive-change` | Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete. | project | `/home/alex/projects/headquarter/.opencode/skills/openspec-archive-change/SKILL.md` |
-| `openspec-explore` | Enter explore mode - a thinking partner for exploring ideas, investigating problems, and clarifying requirements. Use when the user wants to think through something before or during a change. | project | `/home/alex/projects/headquarter/.opencode/skills/openspec-explore/SKILL.md` |
-| `openspec-propose` | Propose a new change with all artifacts generated in one step. Use when the user wants to quickly describe what they want to build and get a complete proposal with design, specs, and tasks ready for implementation. | project | `/home/alex/projects/headquarter/.opencode/skills/openspec-propose/SKILL.md` |

-## Loading protocol
-
-1. Match task context and target files against the `Trigger / description` column.
-2. Pass only the matching `Path` values to the subagent under `## Skills to load before work`.
-3. Instruct the subagent to read those exact `SKILL.md` files before reading, writing, reviewing, testing, or creating artifacts.
-4. If no matching skill exists, proceed without project skill injection and report `skill_resolution: none`.

-name: sift-backlog
-description: Triage and organize backlog tasks into actionable plans. Use when asked to review the backlog, prioritize tasks, create plans from backlog items, or move tasks from backlog to open status. Handles the full workflow of listing backlog tasks, grouping related tasks into plans, setting priorities and dependencies, activating plans, and changing task status from backlog to open.
---
-
-# Sift Backlog
-
-Triage backlog tasks: prioritize, group into plans, set dependencies, and activate.
-
-## Overview
-
-1. List backlog tasks (`sf task backlog`)
-2. Clarify and enrich each task (titles, descriptions)
-3. Identify groupings and create draft plans
-4. Add tasks to plans and set dependencies
-5. Activate plans
-6. Set task status to open
-
-## Workflow
-
-### Step 1: List Backlog Tasks
-
-```bash
-sf task backlog
-```
-
-### Step 2: Clarify and Enrich Tasks
-
-Backlog tasks often have only a brief title with no description. Before organizing, ensure each task is well-defined.
-
-**For each task, evaluate:**
-
- Is the title clear and actionable?
- Is there a description? Check with `sf task describe <task-id> --show`
- Is the scope unambiguous?
-
-**If the title is unclear**, update it:
-
-```bash
-sf update <task-id> --title "Clear, actionable title"
-```
-
-**Add a description** with context, scope, and acceptance criteria:
-
-```bash
-sf task describe <task-id> --content "Description with:
- What needs to be done
- Why it matters
- Acceptance criteria
- Any relevant context"
-```
-
-**Use your best judgment** to interpret tasks and make reasonable decisions about scope, grouping, and priority. You have context about the codebase, project patterns, and typical development practices—leverage this knowledge rather than deferring to the user for routine decisions.
-
-**Only ask the user for clarity when absolutely necessary:**
-
- The task is fundamentally ambiguous (multiple mutually exclusive interpretations)
- Critical business logic or user-facing behavior that could go wrong in meaningful ways
- External dependencies or integrations you cannot verify
-
-**Do NOT ask about:**
-
- Implementation details you can reasonably infer
- Priority or grouping decisions—use your judgment
- Standard development practices (testing, code style, etc.)
- Tasks where a reasonable interpretation exists
-
-### Step 3: Create Draft Plans
-
-Group related tasks into plans using your best judgment. Plans start as drafts (tasks won't be dispatched until activated).
-
-**Grouping guidance:**
-
- Group tasks that share a common theme, feature area, or goal
- Consider technical dependencies when grouping (tasks that touch the same files/modules)
- Separate unrelated work into distinct plans for parallel execution
- Don't over-group—if tasks are truly independent, separate plans enable better parallelism
- Don't under-group—related tasks benefit from shared context and coordinated execution
-
-```bash
-sf plan create --title "Plan Name"
-```
-
-**Example:**
-
-```bash
-sf plan create --title "Authentication Improvements"
-# Output: Created plan el-abc123
-```
-
-### Step 4: Add Tasks to Plans
-
-```bash
-sf plan add-task <plan-id> <task-id>
-```
-
-**Example:**
-
-```bash
-sf plan add-task el-abc123 el-task1
-sf plan add-task el-abc123 el-task2
-```
-
-### Step 5: Set Dependencies Between Tasks
-
-Use `blocks` dependency when one task must complete before another can start.
-
-```bash
-sf dependency add <blocked-id> <blocker-id> --type blocks
-```
-
-**Semantics:** The first ID is blocked BY the second ID. The blocker must complete first.
-
-**Example:** Task 2 can't start until Task 1 completes:
-
-```bash
-sf dependency add el-task2 el-task1 --type blocks
-```
-
-### Step 6: Update Priorities
-
-Set priorities based on your assessment of impact, urgency, and dependencies. Use your judgment—you don't need user confirmation for routine prioritization.
-
-**Priority guidance:**
-
- **Critical (1):** Blocking issues, security vulnerabilities, production bugs
- **High (2):** Important features with deadlines, significant user impact
- **Medium (3):** Standard feature work, most tasks default here
- **Low (4):** Nice-to-haves, minor improvements, tech debt
- **Minimal (5):** Backlog cleanup, documentation, exploratory work
-
-```bash
-sf update <task-id> --priority <1-5>
-```
-
-| Value | Level    |
-| ----- | -------- |
-| 1     | Critical |
-| 2     | High     |
-| 3     | Medium   |
-| 4     | Low      |
-| 5     | Minimal  |
-
-### Step 7: Activate Plans
-
-Once tasks are organized with dependencies set, activate plans to enable dispatch.
-
-```bash
-sf plan activate <plan-id>
-```
-
-### Step 8: Set Task Status to Open
-
-Move tasks from backlog to open so they become ready for work.
-
-```bash
-sf update <id> --status open
-```
-
-## Other Actions
-
-**Close obsolete tasks:**
-
-```bash
-sf task close <id> --reason "Won't do: <reason>"
-```
-
-**Defer tasks:**
-
-```bash
-sf task defer <id> --until <date>
-```
-
-**View existing plans:**
-
-```bash
-sf plan list
-```
-
-**View tasks in a plan:**
-
-```bash
-sf plan tasks <plan-id>
-```
-
-## Tips
-
- **Use your best judgment** for grouping, prioritization, and task interpretation—don't defer routine decisions to the user
- **Only escalate to the user** when ambiguity is fundamental and could lead to wasted work (mutually exclusive interpretations, critical business decisions)
- Make reasonable inferences about implementation details, scope, and priority based on codebase context
- Create plans before setting dependencies to avoid dispatch race conditions
- Always activate plans after dependencies are set
- Focus on oldest backlog items first (sorted by creation date)
- Every task should have a clear title and description before activation
- When uncertain about a minor detail, make a reasonable choice and document it in the task description—workers can ask if needed

 ## Git workflow

-### Branching strategy
-
-For every spec change or new functionality:
-
-1. Create a new branch from `dev` with a proper prefix:
-   - `feat/` for new features (e.g., `feat/tool-workshop`)
-   - `fix/` for bug fixes (e.g., `fix/terminal-tty`)
-   - `refactor/` for refactors (e.g., `refactor/api-cleanup`)
-   - `docs/` for documentation (e.g., `docs/api-guide`)
-   - `chore/` for maintenance (e.g., `chore/update-deps`)
-2. Branch name should reference the OpenSpec change name when applicable.
-3. Do not commit directly to `main` or `dev`.
-
-### Completion and merge
-
-When implementation is complete and verified:
-
-1. Ensure all tests pass and quality gates are met.
-2. Stage all changes with `git add -A`.
-3. Create a commit with a proper conventional commit message (see below).
-4. Switch to `dev`: `git checkout dev`.
-5. Merge the feature branch: `git merge --no-ff <branch-name>`.
-6. Push to remote: `git push origin dev`.
-7. Delete the local feature branch if desired: `git branch -d <branch-name>`.
