Harness-aligned Claude Code marketplace: behavioral steering, context management, memory architecture, evaluation, orchestration, and multi-agent decomposition.
npx claudepluginhub artmin96/forge-studioBehavioral steering via modular hooks: anti-sycophancy, anti-false-claims, destructive command blocking, self-review enforcement, numeric length anchors, scope discipline, minimal change enforcement, plan discipline
Context management: progressive pressure tracking, session handoffs, drift detection, edit safety, large-file warnings, plan mode hooks, MCP monitoring, prompt budget awareness
Three-tier memory architecture: pointer index, on-demand topics, searchable transcripts
Evaluator-optimizer pattern: adversarial review, verification, static analysis gates, postmortems
Orchestration patterns: task routing, explore-plan-implement cycle, daily rituals
Multi-agent decomposition: planner/generator/reviewer triad with tool-isolated capability boundaries
Power-user reference: extended thinking, unix pipes, parallel execution patterns
Execution trace collection, analysis, and harness evolution. Stores structured JSONL traces for pattern detection and failure-driven improvement.
Production-ready workflow orchestration with 75 focused plugins, 182 specialized agents, and 147 skills - optimized for granular installation and minimal token usage
Claude Code marketplace entries for the plugin-safe Antigravity Awesome Skills library and its compatible editorial bundles.

Agent = Model + Harness. The harness is everything except the model: behavioral steering, context management, memory, evaluation, orchestration, and multi-agent decomposition. Research shows changing only the harness can produce a 6x performance gap.
Forge Studio implements harness principles as composable Claude Code plugins.
8 plugins. 33 skills. 17 hooks. 4 agents.

A lean CLAUDE.md template is included at templates/CLAUDE.md. Designed to work with forge-studio plugins — covers personality, judgment, context management, self-evaluation, and project config without repeating what hooks enforce.
cp templates/CLAUDE.md ./CLAUDE.md
# Edit the Project Config and Conventions sections for your project
A power-user settings.json template is included at templates/settings.json. Enables extended thinking, maximum effort, LSP tools, and bypass permissions with a deny list for destructive commands.
# Copy to your global Claude Code config
cp templates/settings.json ~/.claude/settings.json

See docs/architecture.md for the full design rationale.
Re-injects behavioral rules on every message to prevent drift in long sessions. Rules live in rules.d/ as individual files, priority-ordered by numeric prefix (10-no-sycophancy, 20-no-filler, etc.). Add, remove, or reorder rules by managing files. Hooks enforce ~100% compliance where system prompt instructions degrade to ~80%.
| Skill | Purpose |
|---|---|
/rules-audit | Audit session for sycophancy, apologies, scope creep, filler |
/scope <task> | Define task boundaries and acceptance criteria |
/timebox [N] | Set a message budget (default 15) for the current task |
Progressive 5-stage context pressure tracking replaces fixed message-count thresholds. Warns at ~50% (re-read files), ~65% (consider compact), ~75% (recommend compact), ~85% (recommend handoff), ~92% (critical — handoff now). Automatically uses actual context percentage when Claude Code exposes it.
| Skill | Purpose |
|---|---|
/handoff [topic] | Generate a session transfer document |
/resume | Pick up from the latest handoff |
/checkpoint | Mid-session drift and scope creep check |
/audit-context | Analyze token overhead from CLAUDE.md, plugins, MCP servers |
/lean-claude-md [path] | Trim CLAUDE.md to only lines that change behavior |
/context-tricks | Guided compaction, /btw, checkpoints, @ references |
