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 | $0.00025 | $0.00433 |
| Opus 5.5 | $0.00010 | $0.00173 |
| Sonnet 5.5 | $0.00005 | $0.00087 |
| Haiku 4.5 | $0.00003 | $0.00043 |
Grade A, and why
post-devto 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.
What it actually says
Dev.to Adapter
Facts live in platforms/devto.json (≤4 tags, cover image, canonical_url).
Official Forem API — implemented in this adapter.
What Dev.to rewards (culture)
- Teaching. Step-by-step tutorials, honest postmortems, annotated code.
- Beginner-friendly framing travels far; gatekeeping does not.
- Tags are first-class discovery metadata — pick them carefully (≤4).
- Series for multi-part content; canonical_url for syndicated posts.
Drafting from the content graph
core-claim→ descriptive title with the real subject (keywords help).context→ intro: what it is, who it's for.proof/technical→ the body: sections, code blocks, specifics.demo→ "Try it" section with the actual commands.roadmap→ closing "What's next" — Dev.to readers like a thread to pull.cta+ links → footer; canonical_url when the piece is cross-posted.
Publishing
api→DEVTO_API_KEYenv (dev.to/settings/extensions). Default is safe: posts go up as UNPUBLISHED drafts (published: false) unless the item's target setslive: true. A remote draft lets the human do a final in-editor review — prefer it.agent-browser→ playbook for the dev.to/new markdown editor.manual→ full draft package (title, tags, markdown body, cover ref).
Genuine engagement
- Answer comments with real technical help.
- Read and comment on others' articles — Dev.to is a community first.
Pitfalls
-
4 tags → validation error.
- A bare announcement with no teaching value underperforms — the campaign should adapt the launch into a story or a how-it-works piece.
- Rate limits exist; one article per launch is the right cadence.
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.

post-devto is a skill published in the GitHub repository tang-vu/social-posting-skills (12 stars, last pushed 22d ago), licensed MIT. It adds 25 tokens to every session and 433 once invoked, about $0.0001 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.
