sdd-sync

sdd-sync is a skill for Claude Code from 3062-in-zamud/knowledgine. It costs 44 tokens per session (502 once invoked), scanned A, original, MIT.

A synchronization workflow connecting SDD specification tasks with Plans.md, a project planning file. It copies unfinished specification tasks into the plan and reflects completed plan items back into the specification.

In plain words
What is it for?
Use it after creating a specification, after completing planned work, or at the start of a session to synchronize active specs and Plans.md.
Why use it?
It prevents the specification and working plan from drifting apart or requiring the same task to be updated manually in two places.

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

sdd-sync 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 11d 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.

What it actually says

sdd-sync

Purpose

Bridge the SDD workflow (specs/) with the Harness workflow (Plans.md). Ensures both systems stay in sync without manual duplication.

When to Use

  • After creating a new spec (to populate Plans.md)
  • After completing tasks in Plans.md (to update tasks.md)
  • At the start of a session to sync any drift

Arguments

  • $ARGUMENTS (optional): Spec ID (e.g., KNOW-001). If omitted, sync all active specs.

Step-by-Step Instructions

Spec → Plans.md (Forward Sync)

  1. Read specs/KNOW-{NNN}-*/tasks.md
  2. For each unchecked task, generate a Plans.md entry:
### KNOW-001: Push-based capture

Spec: specs/KNOW-001-push-based-capture/

- [ ] Write tests for CaptureListener interface (see design.md §Architecture)
- [ ] Implement CaptureListener (see design.md §Interface Definitions)
- [ ] Write integration tests (see requirements.md AC-1 through AC-3)
  1. Write or update the corresponding section in Plans.md
  2. Preserve any existing Plans.md content that isn't spec-related

Plans.md → Spec (Reverse Sync)

  1. Read Plans.md for completed tasks that reference a spec
  2. Find the corresponding task in specs/KNOW-{NNN}-*/tasks.md
  3. Check off the matching task in tasks.md
  4. Report any tasks completed in Plans.md but not in tasks.md (drift)

Drift Detection

Compare both directions and report discrepancies:

## Sync Report: KNOW-001

### Forward (tasks.md → Plans.md)

- 3 tasks added to Plans.md
- 0 tasks already present

### Reverse (Plans.md → tasks.md)

- 2 completions synced to tasks.md
- 0 drift detected

### Warnings

- (none)

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.
