maf-adapter

maf-adapter is a skill for Claude Code from richfrem/agent-plugins-skills. It costs 28 tokens per session (563 once invoked), scanned A, original, MIT.

An adapter for running and checking Markdown-based agent skills inside Microsoft's Agent Framework, a platform for building software agents. It includes a local simulator and checks whether plugin files match the framework's expected structure.

In plain words
What is it for?
Use it to simulate a skill locally, validate plugin manifests, check command targets, and verify required frontmatter fields.
Why use it?
It helps identify invalid manifests, missing command files, and malformed skill instructions before loading them into the framework.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 plugins/agent-scaffolders/scripts/audit_skill.py plugins/cli-agents/skills/maf-adapter --mode source.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 A, and why

maf-adapter 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 18d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/test_harness.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Microsoft Agent Framework Adapter (maf-adapter)

Validates plugin manifests and simulates agent skill execution within the Microsoft Agent Framework (MAF v1.6/v1.7+).

Contents

Critical Constraints

  • Manifest Hygiene: Manifests loaded into MAF must omit banned/unsupported fields (skills, agents, hooks).
  • Frontmatter Requirement: All skills must include valid YAML frontmatter blocks delimited by --- with name and allowed-tools.
  • Local Simulation First: Test and simulate skills locally via test_harness.py before deploying to Azure Agent Service.
  • Read-Only Test Frame: The simulation harness must execute in read-only mode without mutating the target skill or plugin files.

Quick start

# Validate plugin manifest for MAF compatibility
python3 plugins/cli-agents/scripts/test_harness.py --validate --plugin plugins/<plugin>

# Simulate skill execution locally under MAF
python3 plugins/cli-agents/scripts/test_harness.py \
  --skill plugins/<plugin>/skills/<skill-name> \
  --instruction "Analyze workspace"

Workflow

  1. Phase 1: Manifest Validation: Run test_harness.py --validate against the target plugin directory to verify schema compatibility and absence of banned root keys.
  2. Phase 2: Frontmatter Verification: Verify that the target skill's SKILL.md contains valid frontmatter declaring allowed tools and clean descriptions.
  3. Phase 3: Execution Simulation: Execute test_harness.py --skill with mock input context to assemble and verify the MAF execution frame.
  4. Phase 4: Output Inspection: Review the generated execution frame to verify clean parameter passing and tool bounds.

Verification

# Validate plugin manifest
python3 plugins/cli-agents/scripts/test_harness.py --validate --plugin plugins/cli-agents

# Audit skill compliance
python3 plugins/agent-scaffolders/scripts/audit_skill.py plugins/cli-agents/skills/maf-adapter --mode source

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

maf-adapter is a skill published in the GitHub repository richfrem/agent-plugins-skills (7 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 563 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-03.
