Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00822 |
| Opus 5 | $0.00000 | $0.00411 |
| Sonnet 5 | $0.00000 | $0.00164 |
| Haiku 4.5 | $0.00000 | $0.00082 |
Grade A, and why
sdd-workflow 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 today.
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.
How it starts
The opening of the file, as written. The whole thing — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD Workflow Rules
This project uses Spec-Driven Development (SDD) — specs and docs are the source of truth, code follows.
Key Files
| File | Purpose |
|---|---|
specs/backlog.md |
Sprint backlog — all tickets, statuses, priorities |
specs/01-project-overview.md |
Project vision, goals, constraints |
specs/02-roles.md |
Role definitions (PM, Architect, Dev, QA) |
specs/03-user-stories.md |

Backlog-First Development
Every fix, feature, or change MUST be tracked in specs/backlog.md:
- Check if a ticket already exists for the work
- If not, add one with the correct format (see
update-backlog.mdc) - Set status to 🔄 In Progress when starting
- Set status to ✅ Done when complete
Status Emojis
- 🔲 Not started
- 🔄 In progress
- 🧪 In QA / testing
- ✅ Done
- ⏸️ Blocked / paused
Docs-First Rule
Before modifying any code:
- Read relevant
docs/files for the subsystem you are changing - Read the relevant spec file (
specs/02-06,specs/10) - Implement the change
- Update
docs/to reflect your changes (living documentation)
Documentation directories:
docs/viewer/— Viewer app (React)docs/cli/— CLI tool (Node/TypeScript)docs/methodology/— SDD philosophy and patternsdocs/deployment/— CI/CD and GitHub Pagesdocs/environments/— IDE and terminal setup
Code Conventions
- TypeScript with strict mode enabled
- Zod for runtime validation and schema definitions
- Architecture: repository → service → controller layering
- Frontend: React + Tailwind CSS + Zustand for state
- Testing: Vitest for unit/integration tests
Commit Format
type(scope): description
Types: feat, fix, docs, refactor, test, chore, style
Scopes: cli, viewer, specs, docs, skills, agents
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.

sdd-workflow is a cursor rule published in the GitHub repository Hundia/autospec (4 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 822 tokens. 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.
