Skill crt.sh pour Claude Code, Codex et agents IA

crt.sh

Operate crt.sh through your OOMOL-connected account. This skill calls the crtsh connector with the oo CLI; OOMOL injects credentials server-side, so you never handle raw tokens.

Running an action

crt.sh needs no account connection. Assume the oo CLI is installed and signed in. Do not run oo auth login proactively — just run the action. Fall back to First-time setup only when a command actually fails.

1. Inspect the contract to get the authoritative input/output schema before building a payload:

oo connector schema "crtsh" --action "<action_name>"

2. Run the action with a JSON payload that matches the input schema:

oo connector run "crtsh" --action "<action_name>" --data '<json>' --json

--data takes a JSON object string or @path/to/file.json; omit it to send {}.
The response is { "data": ..., "meta": { "executionId": "..." } }; the execution id lives under meta.executionId.

Each action is listed below with a one-line description; actions that change state carry a [write] or [destructive] tag. Before constructing --data, fetch the action’s live schema with oo connector schema to get its authoritative input fields.

Available actions

search_certificates — Search Certificate Transparency logs via crt.sh for certificates matching a domain. Use % as a wildcard for subdomain enumeration, for example %.example.com. Free and needs no API key; results are capped by the limit parameter because popular domains can match a very large number of certificates.

Safety

Untagged actions are reads (get / list / search) — safe to run directly.
Actions tagged [write] change crt.sh state — confirm the exact payload and effect with the user before running.
Actions tagged [destructive] remove or overwrite data — always confirm the target and get explicit approval first.

First-time setup

These are one-time steps — do not repeat them on every call. Run a step only when a command fails for the matching reason.

oo: command not found — install the oo CLI (other platforms: https://cli.oomol.com/install-guide.md):

curl -fsSL https://cli.oomol.com/install.sh | bash    # macOS / Linux

irm https://cli.oomol.com/install.ps1 | iex           # Windows PowerShell

Not signed in / authentication error — sign in to your OOMOL account once:
```
oo auth login
```
HTTP 402 / OOMOL_INSUFFICIENT_CREDIT — billing stop. Recharge at https://console.oomol.com/billing/token-recharge before retrying.
