Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00037 | $0.01639 |
| Opus 5.5 | $0.00015 | $0.00656 |
| Sonnet 5.5 | $0.00007 | $0.00328 |
| Haiku 4.5 | $0.00004 | $0.00164 |
Grade A, and why
security-sweep 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 16d 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.
This is a copy
100% identical to security-sweep — 18 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 107 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Sweep
Scan the codebase for dangerous constructs, then use the graph to answer the question a flat scanner cannot: can untrusted input actually reach this? A medium-severity finding in a request handler outranks a critical one in dead code, and only the call graph can tell them apart.
Command surface: run the local CLI through the coding harness shell. Examples
use the installed crg command; from a source checkout,
prefix it with uv run. No MCP mapping is required.
Steps
-
Make the graph current with
crg graph build --base HEAD --repo-root "<path>". Findings are attached to graph nodes, so anything unindexed is unscanned. -
Read the active ruleset with
crg security rule_list --engine heuristicbefore scanning, and check which languages each rule declares. This determines what a clean result is worth -- see Coverage Limits below. -
Run the Tier 1 scan:
crg security scan --engine heuristic --repo-root "<path>". It returnstotal,by_severity,by_rule,tags_by_node, andsuppressed_count. Tier 1 is regex matching over the source of function, class, and method nodes -- fast, no external tool, no data-flow analysis. -
Run Tier 2 when it is available:
crg security scan --engine semgrep --repo-root "<path>". Semgrep is an opt-in extra and is not installed by default.- When the CLI is missing the command returns
{"error": ..., "engine": "semgrep"}with a non-zero exit. - Treat that as not run, never as clean. Report Tier 2 as unavailable instead of silently reporting Tier 1 numbers as the whole picture.
- When the CLI is missing the command returns
-
Rank findings by reachability -- the step that makes this a graph sweep rather than a grep. For each tagged node, walk backwards toward the entry points:
crg query query --pattern callers_of --target "<node>" --repo-root "<path>"- Repeat on the callers, two or three hops, until you reach either an entry point (route handler, CLI command, worker, event consumer) or nothing.
- A node with no callers is either dead code or an entry point itself. Distinguish the two before ranking: an unreferenced HTTP handler is the most exposed code in the repository, not the least.
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.

security-sweep is a skill published in the GitHub repository n24q02m/claude-plugins (4 stars, last pushed today), licensed Apache-2.0. It adds 37 tokens to every session and 1,639 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to security-sweep, differing in 18 lines, and is treated as a copy.
