apex-azure-governance-discoveryANALYSIS SKILL — Azure Policy discovery: effective assignments (incl.
Apex Azure Governance Discovery is an agent skill from jonathan-vella/apex. ANALYSIS SKILL — Azure Policy discovery: effective assignments (incl. MG-inherited), definitions/exemptions, effect classification, emits governance-constraints JSON. WHEN: 'Azure policy discovery', 'effective policy assignments', 'governance constraints', '04g-Governance Phase 1', 'refresh governance JSON'. DO NOT USE FOR: artifact writing, architecture mapping.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 22 other files, including scripts and reference files (for example `references/baseline-check.md`, `references/discover-output.md` and `references/effect-classification.md`). Compatibility notes: Requires Python 3.14, Azure CLI on PATH, read access to the target subscription.
It sits in DevOps & Cloud. It works with Microsoft Azure. The repository describes itself as: APEX turns Azure platform engineering requirements into verified, deploy-ready IaC — powered by GitHub Copilot agents, real-time pricing, and built-in compliance. The licence is MIT.
Read from SKILL.md and the folder at commit d0d3f18. It shows what the files ask for, not the result of running them.
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.
Ships 7 files in scripts/ (Python, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
azpythonpytestnpmFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use az and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Requires Python 3.14, Azure CLI on PATH, read access to the target subscription.
From compatibility in the SKILL.md frontmatter.
Apex Azure Governance Discovery loads about 2.1k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 100 tokens; SKILL.md has 702 words of instructions outside code blocks.
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.
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); the scripts in this folder are not scanned.

The skill exposes scripts/discover.py — a single batched REST traversal that
emits the schema-compliant 04-governance-constraints.json envelope. The parent
agent (04g-Governance) invokes it via run_in_terminal, reads a compact
one-line JSON status from stdout, and proceeds to artifact writing without ever
pulling raw Azure REST responses into LLM context.

}The script writes a JSON envelope conforming to
tools/schemas/governance-constraints.schema.json
(schema_version: governance-constraints-v1). Each finding carries both
bicepPropertyPath and azurePropertyPath (always strings — empty "" when
unresolvable, never null), plus category, exemption, and classification
("blocker" | "auto-remediate" | "informational"; exempted Deny/Modify
blockers downgrade to "informational"). Top-level envelope also includes
policies (alias of findings), tags_required, allowed_locations, and
discovery_metadata (L0 attestation envelope — MANDATORY).
For the full per-finding schema and additive fields, read
references/schema.md.
For the L0 envelope spec (shape, completeness-signature algorithm,
end-of-discovery self-check, refresh handoff, consumer protocol,
backward-compatibility rules), read
references/l0-envelope.md.
For the effect classification table and Defender-filter rationale, read
references/effect-classification.md.
The script also writes a sibling .preview.md file (e.g.,
04-governance-constraints.preview.md) with the H2 structure matching the
apex-azure-artifacts template. The agent copies this to
04-governance-constraints.md and annotates placeholder sections only.
References are split into two tiers so the agent loads only what it needs:
Load-always (the minimum to drive the core workflow):
references/terminal-commands.md — pre-built batched commands
(Cmd 1–8) for the entire phase.Load-on-demand (read only when the relevant decision point is reached):
references/effect-classification.md — effect-to-classification mapping, exemption downgrade, Defender filter rationalereferences/schema.md — output JSON envelope, findings[] structure, additive fieldsreferences/l0-envelope.md — canonical L0 envelope spec (shape,
signature algorithm, self-check, refresh handoff, consumer protocol)references/inline-resolution-gate.md — Phase 2.7 protocol +

Apex Azure Governance Discovery fits situations like: : artifact writing; architecture mapping.
Run `npx skills add jonathan-vella/apex --skill apex-azure-governance-discovery -a claude-code`. Or copy the skill folder (.github/skills/apex-azure-governance-discovery in jonathan-vella/apex) into .claude/skills/apex-azure-governance-discovery in your project. Claude Code loads it when a task matches its description.
Run `npx skills add jonathan-vella/apex --skill apex-azure-governance-discovery -a codex`. Or copy the skill folder (.github/skills/apex-azure-governance-discovery in jonathan-vella/apex) into .agents/skills/apex-azure-governance-discovery in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add jonathan-vella/apex --skill apex-azure-governance-discovery -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/apex-azure-governance-discovery, .gemini/skills/apex-azure-governance-discovery, .github/skills/apex-azure-governance-discovery and .opencode/skills/apex-azure-governance-discovery in your project.
Going by SKILL.md and its folder, Apex Azure Governance Discovery needs Python for the scripts in its folder and the command-line tools its instructions call (az, python, pytest and npm). Our summary lists: Python 3. Compatibility (from SKILL.md): Requires Python 3.14, Azure CLI on PATH, read access to the target subscription..
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Apex Azure Governance Discovery is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 15k tokens, read only when the agent opens those files.
