guard

guard is a skill for Claude Code, Codex from MIK-HEAL/SyncPoint. It costs 31 tokens per session (210 once invoked), scanned A, original, Apache-2.0.

A file-protection workflow for SyncPoint, a system that coordinates work between coding agents.

In plain words
What is it for?
Use it to check guard status, create or validate agent sessions, revoke access, unlock emergency access, and audit file changes.
Why use it?
It helps prevent unauthorized file changes by requiring a guarded session token and recording unexpected writes.

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

guard 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 3d 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

File Guard

Step 1: Check Guard Status

syncpoint guard status
syncpoint guard status --verbose

Step 2: Create Guard Session

syncpoint guard session --agent <agentId> --task <taskId>

Save the returned token — it is required for file operations.

Step 3: Validate Token

syncpoint guard validate-token --token <token>

Step 4: Revoke Session

syncpoint guard revoke <sessionId>

Step 5: Audit for Unauthorized Writes

syncpoint guard reconcile

Emergency Access

syncpoint guard unlock

Verification

syncpoint guard status
syncpoint guard validate-token --token <token>
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.
