What is sdd-steering?

A command for creating or updating project memory called steering context. This context records the project's architecture and naming rules, technology stack, and product goals, users, and business background.

Use it to create initial steering files, synchronize them after code changes, or review and improve the project's documented structure, technology, and product context.

It gives coding agents a shared reference for how the project is structured and why it exists. It can also detect differences between the documented context and the current codebase.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 2,033 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

Origin original No closer match found in the catalogue.

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	$0.00000	$0.02033
Opus 5.5	$0.00000	$0.00813
Sonnet 5.5	$0.00000	$0.00407
Haiku 4.5	$0.00000	$0.00203

Security

Grade A, and why

sdd-steering 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 2mo 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.

SDD Steering Command

Generate or update project memory (steering context).

Instructions for Claude

You are executing the /sdd-steering command to generate or update the project's steering context.

What is Steering?

Steering provides project memory for all Claude Code skills. It consists of 3 core files that document:

structure.md - Architecture patterns, directory structure, naming conventions
tech.md - Technology stack, frameworks, tools
product.md - Business context, product goals, users

Your Task

Mode Detection: Determine which mode to use:

Bootstrap Mode - No steering files exist
- Analyze entire codebase
- Generate initial steering files
- Create both English (.md) and Japanese (.ja.md) versions
Sync Mode - Steering files exist, codebase has changed
- Compare current steering with codebase
- Identify discrepancies
- Update steering files to match reality
- Preserve both English and Japanese versions
Review Mode - User wants to review/improve steering
- Present current steering
- Suggest improvements
- Ask user for feedback

Mode 1: Bootstrap (First Time)

Detection

steering/ directory doesn't exist OR
steering/structure.md, steering/tech.md, steering/product.md don't exist

Steps

Analyze Codebase (use Glob, Grep, Read tools extensively):
- Directory structure
- File organization patterns
- Technology stack (package.json, requirements.txt, go.mod, etc.)
- Frameworks detected
- Database technologies
- API patterns
- Testing frameworks
- Build tools
- Deployment configurations
Infer Product Context:
- README.md analysis
- Package descriptions
- Domain concepts from code
- User types from code
Generate Steering Files (Bilingual):

IMPORTANT: Create BOTH English and Japanese versions for each file.

English version is always the reference/source.

Create steering/structure.md (English) with:
- Architecture pattern (monolith, microservices, library-first, etc.)
- Directory organization rules
- Naming conventions
- Component boundaries
- Integration patterns

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-steering is a command published in the GitHub repository nahisaho/CodeGraphMCPServer (14 stars, last pushed 11mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,033 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 2026-08-30.
