How to use Forge to submit headless agent jobs, check status, and retrieve output via MCP tools. Use when the user wants to delegate work to a background agent, run a task on another LLM, or interact with forge.
What this skill does
# Forge: Headless Agent Job Runner Forge runs tasks on LLM agents in the background via a daemon. Interact through MCP tools. ## MCP Tools ### forge_submit Submit a job. Returns a job ID. **Required:** `task` (string) - the prompt/task description. **Optional:** | Parameter | Type | Description | |-----------|------|-------------| | `agent` | string | `claude` (default), `gemini`, `local`, `lmstudio` | | `model` | string | Agent-specific: `sonnet`, `haiku`, `opus`, `gemini-2.5-pro`, etc. | | `timeout` | string | Duration: `30s`, `10m` (default), `1h` | | `input_files` | string[] | File paths to include as context | | `output_format` | string | `markdown` (default), `json`, `yaml`, `code`, `raw` | | `constraints` | string[] | Output validation constraints | | `tags` | string[] | Tags for filtering/organization | ### forge_status Check job status. **Required:** `job_id` (string). ### forge_output Get completed job result. **Required:** `job_id` (string). Returns: output content, metadata (agent, model, duration, tokens, cost). ### forge_list List jobs. **Optional:** `status` filter (`pending`, `running`, `completed`, `failed`), `limit` (default 20). ## Workflow ``` 1. forge_submit → returns job_id 2. forge_status → poll until "completed" or "failed" 3. forge_output → retrieve the result ``` ## Job States `pending` → `claimed` → `dispatched` → `running` → `validating` → `delivering` → `completed` Any state can transition to `failed`. ## Tips - **Daemon must be running** for jobs to process. If jobs stay `pending`, check with `forge_status` or run `/forge:setup`. - **Jobs are async** - submit returns immediately. Poll status or use `forge_list` to monitor. - **Claude agent** uses Claude CLI with full tool use (file editing, bash). Other agents are completion-only. - **Input files** let you pass context files to the job agent. - **Constraints** validate output (e.g., `["non-empty", "min-length:100"]`). ## When NOT to Use - For tasks that should happen in the current session (just do them directly). - When you need interactive back-and-forth with the user during the task. - Forge is for fire-and-forget background work.

skill-development
IncludedComprehensive meta-skill for creating, managing, validating, auditing, and distributing Claude Code skills and slash commands (unified in v2.1.3+). Provides skill templates, creation workflows, validation patterns, audit checklists, naming conventions, YAML frontmatter guidance, progressive disclosure examples, and best practices lookup. Use when creating new skills, validating existing skills, auditing skill quality, understanding skill architecture, needing skill templates, learning about YAML frontmatter requirements, progressive disclosure patterns, tool restrictions (allowed-tools), skill composition, skill naming conventions, troubleshooting skill activation issues, creating custom slash commands, configuring command frontmatter, using command arguments ($ARGUMENTS, $1, $2), bash execution in commands, file references in commands, command namespacing, plugin commands, MCP slash commands, Skill tool configuration, or deciding between skills vs slash commands. Delegates to docs-management skill for official documentation.
reprompter
IncludedTransform messy prompts into well-structured, effective prompts — single or multi-agent. Use when: "reprompt", "reprompt this", "clean up this prompt", "structure my prompt", rough text needing XML tags and best practices, "reprompter teams", "repromptception", "run with quality", "smart run", "smart agents", multi-agent tasks, audits, parallel work, anything going to agent teams. Don't use when: simple Q&A, pure chat, immediate execution-only tasks. See "Don't Use When" section for details. Outputs: Structured XML/Markdown prompt, quality score (before/after), optional team brief + per-agent sub-prompts, agent team output files. Success criteria: Single mode quality score ≥ 7/10; Repromptception per-agent prompt quality score 8+/10; all required sections present, actionable and specific.
adaptive-compaction
IncludedAdaptive add-on policy and recovery layer that decides WHEN to compact, prune, snapshot, or fork -- replacing fixed-percent auto-compaction across Claude Code, Codex, and MCP-capable hosts. Trigger on auto-compact timing or damage: "when should I compact", "is it safe to compact now or start a fresh session", "auto-compact fires too early/mid-task", "switching to an unrelated task but the window still has space", "context rot", "answers get worse the longer the session runs", "the agent forgot the plan or my decisions after it summarized", "add a layer on top that manages context without changing the agent", raising autoCompactWindow to give the policy room, or installing/tuning a cross-tool compaction policy or PreCompact hook -- even when "compaction" is never said but the problem is context-window pressure or post-summarization memory loss. Do NOT use to summarize a conversation, build RAG, write a summarization prompt (decides WHEN not HOW), or answer max-context-length trivia.
agent-skill-creator
IncludedCreate cross-platform agent skills from workflow descriptions. Activates when users ask to create an agent, automate a repetitive workflow, create a custom skill, or need advanced agent creation. Triggers on phrases like create agent for, automate workflow, create skill for, every day I have to, daily I need to, turn process into agent, need to automate, create a cross-platform skill, validate this skill, export this skill, migrate this skill. Supports single skills, multi-agent suites, transcript processing, template-based creation, interactive configuration, cross-platform export, and spec validation.
llm-wiki
IncludedUse when building or maintaining a persistent personal knowledge base (second brain) in Obsidian where an LLM incrementally ingests sources, updates entity/concept pages, maintains cross-references, and keeps a synthesis current. Triggers include "second brain", "Obsidian wiki", "personal knowledge management", "ingest this paper/article/book", "build a research wiki", "compound knowledge", "Memex", or whenever the user wants knowledge to accumulate across sessions instead of being re-derived by RAG on every query.
skill-master
IncludedAgent Skills authoring, evaluation, and optimization. Create, edit, validate, benchmark, and improve skills following the agentskills.io specification. Use when designing SKILL.md files, structuring skill folders (references, scripts, assets), ingesting external documentation into skills, running trigger evals, benchmarking skill quality, optimizing descriptions, or performing blind A/B comparisons. Keywords: agentskills.io, SKILL.md, skill authoring, eval, benchmark, trigger optimization.
