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.

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 | $0.01890 | $0.01890 |
| Opus 5 | $0.00945 | $0.00945 |
| Sonnet 5 | $0.00378 | $0.00378 |
| Haiku 4.5 | $0.00189 | $0.00189 |
Grade A, and why
harness-skills copilot-instructions.md 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 5d 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.
How it starts
The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Harness Skills
This repository contains Claude Code skills for working with Harness.io CI/CD platform. All skills use the Harness MCP v2 server's consolidated tool interface.
MCP v2 Server
All skills use the Harness MCP v2 server which provides 10 generic tools operating across 119+ resource types:
| Tool | Purpose |
|---|---|
harness_list |
List resources with filters and pagination |
harness_get |
Get a single resource by ID |
harness_create |
Create a resource (requires confirmation) |
harness_update |
Update a resource (requires confirmation) |
harness_delete |
Delete a resource (requires confirmation) |
harness_execute |
Run, retry, interrupt, sync, toggle, approve, reject, test_connection |
harness_search |
Cross-resource keyword search |
harness_describe |
Local metadata/schema lookup (no API call) |
harness_diagnose |
Pipeline failure analysis |
harness_status |
Project health overview |
Tools accept a resource_type parameter (e.g., pipeline, secret, template) to target specific Harness resources. Tools also support Harness UI URL auto-extraction for org_id, project_id, resource_type, and resource_id.
Skill Directory
Skills live in skills/<skill-name>/SKILL.md. Each skill folder may contain references/, scripts/, and assets/ subdirectories.
Pipeline & Execution
| Skill | Description |
|---|---|
/create-pipeline |
Generate v0 pipeline YAML (CI, CD, combined, approvals) |
/create-pipeline-v1 |
Generate v1 simplified pipeline YAML |
/create-trigger |
Create webhook, scheduled, and artifact triggers |
/create-template |
Create reusable step, stage, pipeline, and step group templates |
/run-pipeline |
Execute and monitor pipeline runs |
/debug-pipeline |
Diagnose pipeline execution failures |
/migrate-pipeline |
Convert v0 pipelines to v1 format |

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.
- 5d ago First seen · 150 lines · 1,890 tokens per session scan A 4bb5d9d69c32
harness-skills copilot-instructions.md is an instructions file published in the GitHub repository harness/harness-skills (103 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 1,890 tokens to every session, about $0.0095 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 2026-08-30.
