agentic-coding-playbook: Skill for Claude Code

.agents/skills/federal-decision-records/SKILL.md

federal-decision-records is a skill for Claude Code, Codex from GSA-TTS/agentic-coding-playbook. It costs 27 tokens per session (2,017 once invoked), scanned A, original, CC0-1.0.

A record of an architecture or security choice, written in MADR (Markdown Any Decision Records) format and extended for federal compliance. It can create, check, and list these records.

In plain words
What is it for?
Documenting decisions about AI-agent permissions, data classification, infrastructure, authentication, or cryptography. It also helps explain how identified risks were treated.
Why use it?
It keeps the reason for a technical choice, its risks, and related NIST security controls in one audit trail. This helps prepare documentation for an Authority to Operate (ATO) review.

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

This is GSA-TTS/agentic-coding-playbook's own configuration. It tells Claude Code and Codex how to work on agentic-coding-playbook itself, so it is not a mod to install elsewhere.

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

federal-decision-records 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 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.

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.

Federal Decision Records

This skill helps users create, validate, and index architectural and security decision records using MADR (Markdown Any Decision Records) format with federal compliance extensions.

Decision records provide an audit trail linking design choices to NIST controls and risk treatment rationale — required for ATO documentation.

Path Kind Notes
docs/CODING_PRACTICES.md playbook-source Cited as a policy reference for coding decisions. See AGENTS.md §13.1a if not found at this relative path.
docs/SECURITY-CONTROLS.md playbook-source Cited as a policy reference for control guidance. See AGENTS.md §13.1a if not found at this relative path.
docs/TRACEABILITY.md playbook-source The playbook's control-mapping matrix (in the agentic-coding-playbook repo). See AGENTS.md §13.1a if not found at this relative path.
docs/decisions/ target-project Default output directory for generated ADRs in the target repo (Step 5 asks the user to confirm); never resolved via §13.1a.
references/DECISION_CATEGORIES.md, references/ADR_TEMPLATE.md bundled (skill-local) Self-contained regardless of symlink location; not looked up via §13.1a.

When to Use

  • Documenting a decision about AI agent authorization or capabilities
  • Recording data handling or classification decisions
  • Capturing deployment or infrastructure security choices
  • Documenting cryptographic or authentication design decisions
  • Preparing audit trail for ISSO or ATO reviewer
  • When the federal-risk-assessment skill identifies risks that require treatment decisions — document the treatment rationale here

How It Works

This skill has three modes:

  1. Create — Guide the user through creating a new decision record
  2. Validate — Check existing ADRs for format and completeness
  3. Index — Generate a decision record index from frontmatter

Ask the user which mode they need, or infer from context.

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.
