What is agentic-sdd-bootstrap?

A repository setup guide for spec-driven development, a way of planning software work through written specifications before implementation. It creates shared project rules, templates, review checklists, and documentation folders.

Use it when starting or upgrading a repository that needs feature specs, implementation plans, task lists, architecture and code reviews, bug-fix documents, test plans, and release checklists.

It gives agents and developers a durable place to record the project’s goals, decisions, plans, tests, and release checks. This helps keep implementation aligned with reviewed requirements.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00030	$0.00549
Opus 5	$0.00015	$0.00275
Sonnet 5	$0.00006	$0.00110
Haiku 4.5	$0.00003	$0.00055

Security

Grade A, and why

agentic-sdd-bootstrap 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 9d 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.

Agentic SDD Bootstrap

Use this skill when a repository needs the SDD governance layer before feature work starts.

Goal

Create the durable repository artifacts that agents and humans will use as the source of truth.

Required Structure

Prefer this layout unless the repository already has an equivalent convention:

.specify/
  memory/
    constitution.md
  templates/
docs/
  vision.md
  adr/
  review-checklists/
  release-notes/
  retrospectives/
specs/
AGENTS.md

Add CLAUDE.md and GEMINI.md when the user wants those tools to share the same SDD rules.

Bootstrap Steps

Inspect the repo for existing governance files, README, CI, test commands, build commands, and source layout.
Create missing directories only.
Create or update .specify/memory/constitution.md.
Create templates for:
- feature spec
- implementation plan
- tasks
- architecture review
- code review
- bug fix spec
- refactor spec
- migration spec
- test plan
- release checklist
- spec drift report
- retrospective
Create docs/review-checklists/architecture-review.md.
Create docs/review-checklists/code-review.md.
Create or update AGENTS.md with source-of-truth pointers and safety boundaries.
If requested, create or update CLAUDE.md and GEMINI.md with short pointers to the same artifacts.

Constitution Minimum

The constitution must define:

product purpose and users
production quality bar
allowed technologies
disallowed patterns
dependency policy
testing mandates
security mandates
documentation policy
architecture review gate
code review and release gate
amendment process

Safety Boundaries

Default to allowing agents to read, search, draft docs, plan, edit approved feature code, and run tests. Require human approval for:

dependency installs or lockfile changes
database migrations
auth and authorization changes
payment logic
secrets and credentials
production configuration and infrastructure
destructive file operations
deployment and release

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.

agentic-sdd-bootstrap is a skill published in the GitHub repository nawodyaishan/universal-mcp-sync (6 stars, last pushed 1mo ago), licensed MIT. It adds 30 tokens to every session and 549 once invoked, about $0.0002 per session on Opus 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 2026-08-31.

Run a fleet of AI coding agents as live tmux sessions with agent-manager. Use when a developer is running more than one coding agent, needs to see which one is working or blocked, wants to spawn another on an independent task, or wants to review an agent's diff without leaving the terminal.
