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 | $0.00110 | $0.02837 |
| Opus 5 | $0.00055 | $0.01418 |
| Sonnet 5 | $0.00022 | $0.00567 |
| Haiku 4.5 | $0.00011 | $0.00284 |
Grade A, and why
post-generator 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 9d 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 — 255 lines — stays where its author put it; the contents beside it link to each section on GitHub.
post-generator
Turns a sourced angle into per-platform copy, and decides how the post breaks up — which is a copy decision, not a rendering one.
Two failures sit on either side of this job. It goes generic: a model drafting a post reaches for the register it has seen most, which is LinkedIn announcement copy, recognisable within one line and corrosive to the credibility the content was supposed to earn. It goes untrue: softly, and in a way that is hard to catch. A concept becomes a plan, a plan becomes a launch, an exploration acquires a conclusion it never reached. Nobody lies. The draft simply tightens, and the tightened version is wrong.
That second failure is not hypothetical. In the by-hand test that produced this family, the very first draft described five unbuilt skills in language that read as shipped.
Three rules govern this skill:
- Every refusal is visible. What the draft would not say, and why, goes in
## Not claimed. A silent refusal is indistinguishable from an oversight, and it is the section that lets you add something back deliberately with knowledge the record doesn't have. - Composition is proposed, never picked. How an argument is cut across frames changes what each frame says, so it is decided here, with the copy — and offered as concepts that differ on a named structural axis, not on cosmetics.
- Nothing publishes. No posting, no scheduling, no queueing, no transmission to any platform or service, on any surface, permanently. A bad post cannot be un-posted, and pasting it yourself is the last honest review step.
The arc
Four beats, one spine. The mode changes which beat carries the weight, not the structure.
- The tension — what wasn't working.
- The move — what was done about it.
- What it's showing — what surfaced. This beat may say nothing conclusive yet. It is where the honesty rule survives contact with social media, or doesn't.
- Where it goes — the outcome being chased.
What ships with it
2 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.
- 9d ago First seen · 255 lines · 110 tokens per session scan A a8bed63799d7
post-generator is a skill published in the GitHub repository vidhunnan/agentic-skills (2 stars, last pushed 3d ago), licensed MIT. It adds 110 tokens to every session and 2,837 once invoked, about $0.0006 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 2026-08-31.
