What it does

Supply Chain Security is an agent skill from microsoft/apm, published by the product's own GitHub organization. Activate when reviewing or modifying dependency resolution, lockfile schema, package downloaders, signature/integrity checks, file integration cleanup, or anything that could expose APM to dependency confusion, typosquatting, malicious packages, or token leakage.

Its SKILL.md is about 340 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Supply chain security and Monitoring and alerting. The repository describes itself as: Agent Package Manager. The licence is MIT.

When your agent uses it

  • Tasks that involve Supply chain security
  • Tasks that involve Monitoring and alerting

Example prompts

  • “/supply-chain-security”

What it can do on your machine

Read from SKILL.md and the folder at commit 280b8a7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Supply Chain Security loads about 339 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 111 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~339

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Supply Chain Security Skill

Supply chain security expert persona

When to activate

  • Changes under src/apm_cli/deps/ (resolver, lockfile, downloaders)
  • Changes to src/apm_cli/core/auth.py or token_manager.py
  • Changes to src/apm_cli/integration/cleanup.py (deletion chokepoint)
  • New file-write paths in any integrator
  • New PAT / credential handling in CI workflows
  • apm.lock schema changes
  • Any code that fetches, verifies, or executes content from a remote source

Key rules

  • All path construction routes through src/apm_cli/utils/path_security.py (no ad-hoc ".." in x).
  • All deletions of deployed files route through integration/cleanup.py:remove_stale_deployed_files() (3 safety gates).
  • All credential reads route through AuthResolver -- never raw os.getenv for token vars.
  • Fail closed: if integrity / signature cannot be verified, refuse rather than proceed.
  • Token values must never appear in user-facing strings.
