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 | $0.00167 | $0.01507 |
| Opus 5.5 | $0.00067 | $0.00603 |
| Sonnet 5.5 | $0.00033 | $0.00301 |
| Haiku 4.5 | $0.00017 | $0.00151 |
Grade A, and why
ad-onprem-ldap 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ad-onprem-ldap
One CLI, Tools/Ad.ts, speaks LDAP over TLS straight to the domain controllers. It does what the
RSAT ActiveDirectory cmdlets do for users and groups, and it works anywhere bun runs.
Setup
- Network path to a DC on 636/TCP (usually the corporate VPN) and DNS that resolves the domain.
bun installinsideTools/.op(1Password CLI) signed in. The bind password is read withop readinto memory only.- A config at
~/.config/ad-onprem/config.json(orAD_ONPREM_CONFIG), shaped likeconfig.example.json. It holds the domain, base DN, DCs, bind account, secret reference, CA bundle path and the OU allowlist for creates and moves. It never belongs in a repo. - The CA bundle (root, then any issuing CA) that signed the DC certificates, in PEM. Confirm the root fingerprint with the directory team before trusting it.
Commands
| Command | Does |
|---|---|
find-user <id> / find-user --prefix <text> |
One user by sAMAccountName, UPN or DN, or up to 50 by prefix |
find-group <id> |
Group, decoded scope and type, direct member count |
group-members <group> [--recursive] |
Direct members (ranged, complete), or the nested closure |
user-groups <user> [--recursive] |
Direct memberOf, or every group reached through nesting |
user-status <user> |
Enabled, locked, password expired, last logon, bad password count |
add-member / remove-member <group> <member>... |
Change membership (members may be users, groups or computers) |
create-user <sam> --ou --given --sn [--display] [--upn] |
New user, created disabled |
create-group <sam> --ou [--scope] [--type] [--description] |
New group, global security by default |
disable / enable / unlock <user> |
Account state |
move <object> --to <ou> |
Move to another OU |
reset-password <user> [--must-change] [--vault] |
New random password, stored in 1Password; only the op:// ref is printed |
set-group-scope <group> --scope <scope> |
Scope change; refuses global <-> domain local, which AD only allows via universal |
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

ad-onprem-ldap is a skill published in the GitHub repository julianobarbosa/claude-code-skills (14 stars, last pushed 11d ago), licensed MIT. It adds 167 tokens to every session and 1,507 once invoked, about $0.0007 per session on Opus 5.5. 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 2026-10-14.
