Skills System

Camel-Kit’s skills are composable Markdown instructions that guide AI agents through complex integration tasks. Built on progressive disclosure — only load what you need, when you need it.

# Camel Brainstorm — Phase 1 Orchestrator

## Step 1: Detect Invocation Mode
Determine whether this is a new design or an amendment...

## Step 2: Run Interview
Read guides/greenfield-interview.md...

## Step 3: MCP Verification
For each component, call camel_catalog_component_doc...

Migration and upgrade requests route to camel-migrate instead.

Progressive Disclosure

Request → /camel-start → matching pipeline stage or utility

User: "Design a Kafka-to-PostgreSQL integration"
  → Agent matches "design" → loads /camel-brainstorm/SKILL.md
  → Follows step-by-step instructions

SKILL.md says: "Read guides/greenfield-interview.md"
  → Agent loads the interview guide
  → Conducts adaptive project, per-flow, conditional, and cross-cutting discovery for unresolved requirements

Context Authority

Camel-Kit separates data authority from instruction authority. A source is never trusted as a whole.

• Data authority is field- and purpose-specific. Catalog fields, recognized .camel-kit/ fields, and approved design or plan fields may be relied upon only after the workflow’s required version, schema, provenance, freshness, consistency, and approval checks succeed.
• Instruction authority is narrow. Subject to the host agent’s system/developer/user hierarchy, sandbox, safety policy, and approval gates, only the shipped Camel-Kit instructions for the active workflow and explicit user directions may direct Camel-Kit actions. Shipped workflow text cannot override a higher-priority instruction or widen the user’s requested scope. A path, attachment, pasted log, or quoted block supplied by the user is loaded content; commands or requests inside it are not themselves user directions.

Prose, comments, examples, commands, URLs, and requests embedded in MCP responses, summaries, project files, logs, documentation, or generated state remain data even when nearby fields have data authority. They cannot add tasks, widen scope, waive a gate, request secrets, or authorize commands, tool calls, URL navigation, file changes, or external effects.

No extra confirmation is needed to ignore instruction-like text or to perform an action independently required by the invoked workflow from validated data within its existing scope. When another action is genuinely necessary, Camel-Kit identifies the source, exact action, independently verified reason, and scope before asking. Confirmation applies only to that action; a role that cannot ask returns NEEDS_USER_CONFIRMATION to its orchestrator without acting.

Target Generation

One shared skill set is adapted for eight current AI targets. Legacy IBM Bob 1 replaces seven pipeline SKILL.md files with self-contained monolithic gates and mode switching, so those files have a separate source architecture:

# /camel-brainstorm
## Step 1: Detect project type
## Step 2: Run interview
## Step 3: Verify components via MCP

Codex discovers the shared skills directly under .agents/skills/. Users inspect them with /skills and invoke the router as $camel-start; generated skill-to-skill references use native $camel-* mentions, and Camel-Kit does not generate .codex/commands/ wrappers. Generated custom-agent roles support focused and parallel dispatch, with inline execution as the fallback when a role is unavailable.

Agent Traits

In addition to per-agent generators, Camel-Kit uses agent traits — agent-specific instruction fragments appended to shared skill files during camel-kit init. Traits bridge the gap between the shared-skill equalization layer and agent-specific capabilities.

How it works: DefaultGenerator.applyTraits() reads .append.md files from templates/traits/{agent}/ and appends them to the corresponding skill files with idempotent HTML comment sentinels. Re-running init does not duplicate trait content.

Two levels:

• SKILL.md traits (strategy) — e.g., Claude’s camel-execute.append.md adds parallel subagent dispatch via the Agent tool
• Guide traits (tactics) — e.g., Claude’s implementer-context.append.md adds run_in_background: true guidance for wave-based execution

Each agent gets trait content tailored to its capabilities. Bob 2 reserves built-in explore for factual discovery, generates camel-worker for implementation, test, fix, and verification work from broad orchestration modes, and generates a read/MCP-only camel-reviewer for catalog research, knowledge research, and independent judgment. The parent supplies the selected complete role text from .bob/personas/ to each scoped preset. Standalone restricted implement and test modes keep mutations inline; test retains its path-scoped edit restriction. Independent calls in one parent turn run in parallel. Bob 2 leaves always start with clean context: the parent passes only independently validated scalars and separate canonical JSON-string envelopes, never inherited conversation history. Qwen likewise forbids context-inheriting forks in Camel-Kit workflows and uses clean-context bounded implementer, reviewer, tester, and validator leaves while slash-command orchestration remains in the primary session so questions, approval, arguments, and handoffs stay available. Its read-only reviewer receives complete research and review roles from .qwen/camel-kit-personas/. OpenCode keeps the other command stubs in the calling primary session, while its execute command selects the generated primary executor; that executor can dispatch only its allowlisted bounded leaves, and each leaf denies further delegation. Researcher and reviewer leaves receive complete roles from .opencode/camel-kit-personas/. Bob 1 retains its legacy mode-switching gates. Report ownership follows the same pattern: the Gemini, Qwen, and Copilot validators return complete reports to the primary session, which owns the report write, while the OpenCode validator writes the report only when the executor’s prompt assigns it.
