synapse-feature

synapse-feature is a skill for Claude Code, Codex from JosephOIbrahim/Synapse. It costs 0 tokens per session (261 once invoked), scanned A, original, MIT.

A workflow for developing SYNAPSE features that touch multiple files and require architecture checks. SYNAPSE is an agent system that connects coding work with Houdini, a 3D visual-effects application.

In plain words
What is it for?
Use it to implement multi-file SYNAPSE features, run the project’s Python tests, validate architecture rules, and identify when Houdini integration files need redeployment.
Why use it?
It keeps edits in the repository source instead of deployed copies and checks imports, conventions, tests, and accidental path changes. It also requires a plan before editing.

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

synapse-feature 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 4d 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

Implement SYNAPSE Feature

Autonomous multi-file feature development with architectural validation.

Critical Rules

  1. NEVER edit files under ~/.synapse/houdini/ (deployed copies) — ALL edits must go to the repo source at SYNAPSE/houdini/.
  2. After every file edit, verify: the edited file is in the correct repo directory, all imports resolve, and the change is consistent with He2025 conventions.
  3. Before marking complete, run a final validation that greps for any accidental edits to deployed paths.

Workflow

  1. Read the existing architecture in the relevant source directories
  2. Propose a file-by-file implementation plan — do NOT begin editing until the user approves the plan
  3. Implement each file change, validating after each edit
  4. Run tests: python -m pytest tests/ -v
  5. Final validation: confirm no deployed-path edits, all imports resolve, He2025 compliance (sort_keys=True on all json.dumps)
  6. Report what changed and remind user to redeploy if Houdini integration files were modified

Arguments

The user should describe the feature after invoking this skill:

Changes

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.

synapse-feature is a skill published in the GitHub repository JosephOIbrahim/Synapse (10 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 261 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 2026-08-31.
