SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00069 | $0.02708 |
| Opus 5 | $0.00034 | $0.01354 |
| Sonnet 5 | $0.00014 | $0.00542 |
| Haiku 4.5 | $0.00007 | $0.00271 |
Grade A, and why
synapse-manager 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.
How it starts
The opening of the file, as written. The whole thing — 291 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Synapse Manager
Orchestrate multi-agent work with structured delegation, monitoring, and quality gates.
Task Board Rule
Every delegation MUST have a matching task board entry.
Before sending work to any agent via synapse send, you must:
synapse tasks create "<task>" -d "<description>"— register the work unitsynapse tasks assign <id> <agent>— record ownership- Only then
synapse send <agent> "..." --force
Task board is the team contract — it makes ownership, blocking, and completion state visible to every agent. TodoList is for your personal micro-step tracking only.
When to Use
- Coordinating 2+ agents on related subtasks
- Monitoring progress of delegated work
- Verifying agent outputs (tests, file changes, integration)
- Sending targeted feedback with error details and fix guidance
- Orchestrating cross-review between agents
- Implementing a multi-phase plan (3+ phases or 10+ file changes)
- Planning agent assignment for multi-file changes
Workflow (7 Steps)
Step 1: Plan, Spec, and Setup
New tests first. Follow this order for every implementation task: create tests -> present/confirm spec -> then implement.
Edit plugins/synapse-a2a/skills/ first, then sync generated copies with sync-plugin-skills.
Task board is the default coordination surface for manager-led work. Create or refresh task board entries before delegation starts so ownership, blocking, and completion state are visible to the whole team.
Check existing agents before spawning — reuse is faster (avoids startup overhead, instruction injection, and readiness wait):
synapse list
Review WORKING_DIR, ROLE, STATUS, TYPE. Only READY agents can accept work immediately.
Spawn only when no existing agent can handle the task:
synapse spawn claude --worktree --name Impl --role "feature implementation"
synapse spawn gemini -w --name Tester --role "test writer"
Cross-model spawning (Claude spawns Gemini, etc.) provides diverse strengths and distributes token usage across providers, avoiding rate limits.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 11d ago First seen · 291 lines · 69 tokens per session scan A 44006474726c
synapse-manager is a skill published in the GitHub repository s-hiraoku/vscode-sidebar-terminal (21 stars, last pushed yesterday), licensed MIT. It adds 69 tokens to every session and 2,708 once invoked, about $0.0003 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 2026-09-01.
