What is skill-server AGENTS.md?

Repository instructions for SkillServer, a self-hosted registry for AI-agent skills. They define the project’s identity, Git workflow, permitted changes, required approvals, and where broader project context is documented.

Use them to choose the correct development branch and remote, understand what work is allowed, identify changes needing approval, and follow the project’s contribution process.

They reduce mistakes around branches, remotes, releases, and changes that require escalation, especially when contributing to a shared repository.

Token cost

What it costs to keep this loaded

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	$0.00874	$0.00874
Opus 5.5	$0.00350	$0.00350
Sonnet 5.5	$0.00175	$0.00175
Haiku 4.5	$0.00087	$0.00087

Security

Grade A, and why

skill-server AGENTS.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 2mo 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.

SkillServer Agent Constitution

Identity

You are an engineering agent working on SkillServer, a self-hosted skill registry for AI agents. This is a Petabridge project under Apache-2.0 license.

Git Workflow

Most contributors work from forks. upstream is the canonical repo (netclaw-dev/skill-server). origin is the personal fork.

All pushes go to upstream. Everything must go upstream for it to be real.
Branches: Create feature branches off upstream/dev, push to upstream, open PRs against upstream/dev.
Tags: Always create and push tags to upstream (e.g., git push upstream <tag>).
Pull: Sync from upstream/dev before starting work.
Never push to origin unless explicitly asked to.

Authority

You may:

Implement features, fix bugs, refactor code
Create/modify tests, documentation, CI workflows
Make architectural decisions within established patterns

You must escalate:

Breaking API changes (wire format, public client API)
New external dependencies
Changes to release/versioning process
Security-sensitive modifications

Project Context

Read docs/PROJECT_CONTEXT.md for:

Architecture and design constraints
Standards implemented (AgentSkills.io, Cloudflare RFC, NetClaw)
Project structure and ownership

Read docs/TOOLING.md for:

Build, test, and deployment commands
CI/CD workflow structure
Local development setup

Quality Bar

Code Standards

AOT-ready: No reflection-based serialization; use source generators
Sealed by default: Seal classes unless designed for inheritance
Copyright headers: All .cs files require Petabridge headers (run scripts/Add-FileHeaders.ps1)
No comments explaining what: Code should be self-documenting; comment only non-obvious why
No Slopwatch violations: dotnet slopwatch analyze must pass — no new violations (see baseline at .slopwatch/baseline.json)

Testing Requirements

Unit tests for business logic and value objects
Integration tests for API endpoints using WebApplicationFactory
All tests must pass on both ubuntu and windows

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.
