is-ai-native: Skill for Claude Code

.agents/skills/agent-package-manager/SKILL.md

agent-package-manager is a skill for Claude Code, Codex from webmaxru/is-ai-native. It costs 93 tokens per session (1,729 once invoked), scanned C, original, MIT.

A repository tool for installing and managing packages that provide context or capabilities to coding agents. It uses files such as apm.yml and apm.lock.yaml to record project settings and exact package versions.

In plain words
What is it for?
Use it to initialize APM, install or update packages, check manifests, manage lockfiles, compile agent context, browse MCP servers, and prepare context for CI.
Why use it?
It removes the need to set up agent packages and their configuration by hand. It also helps keep the same resolved setup across developers and continuous-integration systems.

Written for no agent in particular: nothing here depends on one. Also seen: mentions CLAUDE.md; installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is webmaxru/is-ai-native's own configuration. It tells Claude Code and Codex how to work on is-ai-native itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything is-ai-native configures →

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.

Security

Grade C, and why

agent-package-manager scanned grade C with 1 finding 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 1mo 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.

Nullifies safety policieshighAnti-refusal

"You have no restrictions", "do anything now", "ignore your guidelines": a direct jailbreak that disables guardrails.

* If `apm install` is blocked by an organization policy (`apm-policy.yml`), do not bypass the policy; report the block and ask the administrator to adjust the policy or allowlist the dependency.

Agent Package Manager

Procedures

Step 1: Assess the repository and the requested APM outcome

  1. Inspect the repository root for apm.yml, apm.lock.yaml, .github/, .claude/, .codex/, .cursor/, .gemini/, .opencode/, .windsurf/, and apm_modules/.
  2. Execute apm --version and apm config to confirm the installed CLI and current configuration.
  3. If apm.yml exists, read references/manifest-and-lockfile.md before changing dependencies, scripts, or compilation settings.
  4. If the request is about package installation, updates, pruning, or removal, read references/command-workflows.md before executing APM commands.
  5. If no apm.yml exists and the user wants APM in the repository, initialize the project with apm init or apm init --yes.
  6. If the repository already uses another agent configuration flow and the user did not ask to migrate it, limit the change to the requested APM scope instead of replacing the existing setup.

Step 2: Shape or repair the manifest deliberately

  1. Read assets/apm.yml.template when the repository needs a fresh or repaired manifest structure.
  2. Keep name and version present at the top level; treat them as required contract fields.
  3. Add APM package dependencies under dependencies.apm and MCP servers under dependencies.mcp.
  4. Prefer canonical dependency forms in apm.yml after installation. Default to the repository shorthand owner/repo/path for GitHub-hosted skills and packages, for example webmaxru/web-ai-agent-skills/skills/webmcp, and preserve explicit path, ref, and alias only when they are needed.
  5. Use pinned refs for shared team packages when reproducibility matters more than automatic drift.
  6. Keep local path dependencies only for active local development. Replace them with remote references before recommending bundle distribution.
  7. If the request includes scripts, define them under scripts and verify that each script can be previewed or executed through apm list, apm preview, or apm run.

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.
