SkillSpector: 3 findings, up to high
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 →
- high Rogue Agent · line 54 Skill modifies its own code, configuration, or behavior at runtime. Self-modification enables an agent to escalate privileges, disable safety constraints, or install persistent backdoors.Fix: Prevent the skill from modifying its own code, SKILL.md, or configuration files.

Skills should operate independently; cross-skill access is a privilege escalation.
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 | $0.00078 | $0.00851 |
| Opus 5 | $0.00039 | $0.00426 |
| Sonnet 5 | $0.00016 | $0.00170 |
| Haiku 4.5 | $0.00008 | $0.00085 |
Grade A, and why
sync-plugin-skills 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.

Sync Plugin Skills
Synchronize plugin skills with the current implementation and documentation.
Purpose
Ensure that skills in plugins/synapse-a2a/skills/ accurately reflect:
- Current implementation in
synapse/directory - README.md documentation
- Guides in
guides/folder
When to Use
- After implementing new features or parameters
- After updating README.md or guides
- Before releasing a new version
- When
/sync-plugin-skillsis invoked
Workflow
Step 1: Gather Current State
Read the following files to understand current implementation and documentation:
-
Implementation: Key files in
synapse/synapse/tools/a2a.py- CLI tool implementationsynapse/a2a_client.py- A2A clientsynapse/cli.py- Main CLI entry pointsynapse/commands/*.py- Command implementations
-
Documentation:
README.md- Main documentationguides/usage.md- Usage guideguides/settings.md- Settings documentation
-
Current Skills:
plugins/synapse-a2a/skills/synapse-a2a/SKILL.mdplugins/synapse-a2a/skills/synapse-a2a/references/*.md
Step 2: Identify Gaps
Compare and identify:
- New CLI options/parameters not documented in skills
- Changed command syntax or behavior
- New features mentioned in README but missing from skills
- Deprecated or removed features still in skills
- Endpoint path inconsistencies
Step 3: Update Skills
Update skill files to match current state:
synapse-a2a/SKILL.md:
- Quick Reference table
- Command examples
- Feature descriptions
synapse-a2a/references/commands.md:
- Full CLI command documentation
- All options and parameters
- Example usage
synapse-a2a/references/api.md:
- Endpoint paths
- Request/response formats
- Extension endpoints
Step 4: Verify Consistency
Ensure consistency across:
- Endpoint paths match between README and skills
- Command syntax is identical
- Option names and defaults match implementation
- Examples use correct syntax
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 · 128 lines · 78 tokens per session scan A 7665427e4765
sync-plugin-skills is a skill published in the GitHub repository s-hiraoku/vscode-sidebar-terminal (21 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 851 once invoked, about $0.0004 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.
