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.

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 | $0.00052 | $0.02418 |
| Opus 5 | $0.00026 | $0.01209 |
| Sonnet 5 | $0.00010 | $0.00484 |
| Haiku 4.5 | $0.00005 | $0.00242 |
Grade A, and why
gated-reach 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 8d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Measured 2026-07-25, residential network. Ship-tier channels only: Reddit (text, and ranking/structure) and single-tweet reads. Every surface here is undocumented or at-will — re-verify before relying on a number.

Native tools first — this skill is the exception, not the default
Try the host's own web search / fetch first. A pre-registered benchmark found that a prescription layer buys no capability the host already has on ordinary credential-free dev research: native passed 12/12, the prescriptions won 0 outright. This skill exists only for the narrow set where native genuinely cannot reach the content at all.
Fires when one of these is observed, not assumed:
reddit.com— the host's web tool refuses the domain (a client-side refusal, not a 403 from Reddit).x.com/<user>/status/<id>— answers HTTP 402.
When the agent should load this
Load this skill when all three hold — anything less and the native tools win:
- The target is a Reddit thread permalink or a single tweet URL. Not a timeline, not a search, not a plain web page.
- The host's own fetch has actually been refused for that URL (domain refusal, or HTTP 402) — observed this turn, not assumed from this file.
- The answer needs the platform's own content, not a report about it. If a summary from a news article or a cross-post would do, native search is cheaper and already sufficient (measured: native recovers canonical tweets 5/6).
Do not load it to explain that a platform is unreachable — that answer needs no
skill. Do not load it for YouTube: that channel is parked, and reach:doctor states
why in one line.
When to use
- A Reddit thread's post text or comment text is needed and the domain is refused.
- Which comment the community actually upvoted, or how replies nest — a flat text feed cannot answer that.
- A specific tweet URL is in hand and its content is needed verbatim.
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.

gated-reach is a skill published in the GitHub repository event4u-app/agent-config (10 stars, last pushed today), licensed MIT. It adds 52 tokens to every session and 2,418 once invoked, about $0.0003 per session on Opus 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 2026-09-03.
