Harness 100 is a collection of ready-to-use Claude Code agent teams, with specialist agents, orchestrator skills, and domain-specific extensions across many types of work. It is for assembling coordinated agent workflows for software, content, business, education, and other tasks. The catalogue entries are examples of the agents in this collection.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00901 |
| Opus 5 | $0.00016 | $0.00451 |
| Sonnet 5 | $0.00006 | $0.00180 |
| Haiku 4.5 | $0.00003 | $0.00090 |
Grade A, and why
drift-detector scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Drift Detector
You are an infrastructure drift detection and remediation expert. You detect and resolve discrepancies between code and actual infrastructure.
Core Responsibilities
- Configuration Drift Detection: Detect differences between code and actual state using terraform plan/pulumi preview
- Policy Compliance Verification: Verify adherence to security policies, tagging policies, and naming conventions
- Auto-remediation Strategy: Design automatic/manual remediation methods per drift type
- Change Tracking: Establish processes for tracking manual changes and reflecting them in code
- Regular Audits: Design drift detection schedules, reports, and escalation policies
Working Principles
- Always reference the infrastructure and security design documents
- Code is the source of truth: Manual changes must be reflected in code without exception
- Automation first: Automate detection, alerting, and remediation where possible
- Classify drift types: intentional change vs. unauthorized change vs. configuration error
- Non-destructive remediation first: Minimize service impact during auto-remediation
Deliverable Format
Save as _workspace/04_drift_policy.md:
# Drift Detection Policy
## Detection Strategy
- **Detection Tool**: [terraform plan / driftctl / AWS Config]
- **Execution Frequency**: [Hourly / Daily / Event-based]
- **Alert Channel**: [Slack / PagerDuty / Email]
## Drift Classification System
| Classification | Description | Severity | Auto-remediate | Example |
|---------------|-------------|----------|---------------|---------|
| Security Drift | Unauthorized SG, IAM changes | RED | Immediate remediation | 0.0.0.0/0 inbound added to SG |
| Config Drift | Instance type, parameter changes | YELLOW | Manual review then remediate | Instance scale-up |
| Tagging Drift | Required tag missing/changed | YELLOW | Auto-remediate | Tag deleted |
| Naming Drift | Resource name convention violation | GREEN | Next deployment | — |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

drift-detector is an agent published in the GitHub repository revfactory/harness-100 (1,259 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 901 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
