Agentic Tools is a marketplace of plugins and skills for managing Meta Social Technologies applications, including settings, webhooks, compliance, app review, and API health. Developers use it with coding agents such as Claude Code, Cursor, and Codex through Meta's remote MCP server. The catalogue contains the project's agent add-ons.
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.

SkillSpector: 13 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.02061 |
| Opus 5.5 | $0.00038 | $0.00824 |
| Sonnet 5.5 | $0.00019 | $0.00412 |
| Haiku 4.5 | $0.00009 | $0.00206 |
Grade A, and why
debug-access-token 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 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.
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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Debug Access Token
Help a developer figure out why a Meta access token is failing — without ever handling the raw token yourself.
Security first — never handle a live token
An access token is a bearer credential: whoever holds it can act as its owner. Anything pasted into this chat enters the agent's context and is transmitted to the AI provider (logs, history, retention). Treat a token like a password.
- Do NOT ask the developer to paste an access token (or an app secret) into this chat. Inspect tokens using the developer-run options below, and ask only for the resulting metadata.
- If a token was already pasted, tell the developer to revoke/rotate it (Graph API Explorer, or the app dashboard → regenerate), then continue with the metadata flow below using a fresh token.
Workflow
-
Confirm the symptom. Ask what failed:
- The error
codeandsubcode(e.g.190/463) - Which endpoint/request failed
- Which app the call was made with, and what the token is expected to do (which permissions/scopes)
- The error
-
Have the developer inspect the token themselves. Offer either option — both run in the developer's own environment and return only metadata, never routing the token through this agent:
- A. Access Token Debugger (web): open https://developers.facebook.com/tools/debug/accesstoken/, paste the token there (a Meta first-party surface, not this agent), and read the results panel.
- B.
debug_tokenGraph API via the bundled script: this skill ships a ready-to-run script,scripts/debug_token_probe.py, that reads the token and app secret from environment variables (by name — never their values) and prints only redacted metadata; the developer sets the env vars and runs it in their own shell, then brings back only the printed JSON. See the Using thedebug_tokenscript section below for how to run it and the expected output. Reference: debug_token docs. Never ask the developer to send you the token or the app secret.
What ships with it
1 file 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.

debug-access-token is a skill published in the GitHub repository facebook/agentic-tools (15 stars, last pushed 6d ago), licensed MIT. It adds 94 tokens to every session and 2,061 once invoked, about $0.0004 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 2026-08-31.
