Skills — Overview

A skill in processkit is a directory containing agent instructions, examples, assets, and optionally a Python MCP server. Skills are how processkit gives agents domain-specific intelligence — not just instructions, but the conventions, gotchas, and decision rules of a domain expert.

Skill package layout

src/context/skills/<category>/<skill-name>/
  SKILL.md              ← agent instructions (Intro / Overview / Gotchas / Full reference)
  examples/             ← example outputs
  assets/               ← templates, reference data, reusable artifacts
  references/           ← optional deep-dive material (keeps SKILL.md under 5 000 words)
  scripts/              ← optional helper scripts
  mcp/                  ← optional Python MCP server

The four-section structure

Every SKILL.md is organized so agents can stop reading as soon as they have enough context:

Section	Content
Intro	1–3 sentences — enough to decide "is this skill relevant?"
Overview	Key workflows and common operations — enough to act on typical cases
Gotchas	7 agent-specific failure modes — where agents most often go wrong
Full reference	Edge cases, field-by-field specs, troubleshooting

The Gotchas section is the highest-signal content: 7 provider-neutral failure modes, each with a bold title, the specific failure pattern, and the specific countermeasure.

Frontmatter

Each SKILL.md opens with YAML frontmatter:

---
name: workitem-management
description: |
  Creates, transitions, and queries WorkItems — the task-tracking primitive
  in processkit. Use when managing backlog items, updating work item state,
  or querying items by status, owner, or priority.
metadata:
  processkit:
    apiVersion: processkit.projectious.work/v1
    id: SKILL-workitem-management
    version: "1.0.0"
    created: 2026-04-06T00:00:00Z
    category: process
    layer: 2
    uses:
      - skill: event-log
        purpose: "records state transitions as auditable log entries"
    provides:

      mcp_tools: [create_workitem, transition_workitem, query_workitems]
      assets: [workitem, workitem-bug, workitem-story]

Current catalog (140 skills)

Category	Count	Examples
Processkit operations	40+	workitem-management, decision-record, processkit-gateway, task-router, skill-gate
Engineering and devops	45+	python-best-practices, fastapi-patterns, terraform-basics, incident-response
Data, AI, and research	20+	data-science, rag-engineering, llm-evaluation, research-with-confidence
Product, design, and documents	25+	prd-writing, user-research, frontend-design, docx-authoring
Role and coordination workflows	10+	session-handover, standup-context, retrospective, team-manager

All skills are Pattern 5 (domain-specific intelligence): they encode what an expert in the domain carries in their head — conventions, gotchas, and decision rules — so the agent reasons like a specialist, not a generalist.

Browsing the skill catalog

Three ways to find skills:

On GitHub — Browse the source tree directly: src/context/skills/ is organized into 7 category subdirectories (processkit/, engineering/, devops/, data-ai/, product/, documents/, design/). Each skill directory contains a SKILL.md with the full description, gotchas, and reference.

From a release tarball — Every GitHub release includes a processkit-vX.Y.Z.tar.gz with all src/ content. Download and unpack to inspect or diff skills without cloning the full repo. Release assets live at: github.com/projectious-work/processkit/releases

In an installed project — Skills are installed under context/skills/<category>/<skill-name>/SKILL.md. The task-router MCP server's route_task(task_description) call returns the matching skill, any legacy process override metadata, and the recommended MCP tool in a single call. skill-finder (find_skill, list_skills) is called internally by task-router and remains available directly. The index-management MCP server's search_entities tool can query skill metadata from the SQLite index.
