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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00157 | $0.03455 |
| Opus 5 | $0.00078 | $0.01728 |
| Sonnet 5 | $0.00031 | $0.00691 |
| Haiku 4.5 | $0.00016 | $0.00346 |
Grade A, and why
sonar-onboard 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 — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.
sonar-onboard
Scaffolds the artifacts a repo needs to become Sonar-compliant: a sonar-project.properties keyed to the project's actual language and layout, a CI workflow that runs the scanner and enforces the quality gate, and a README block so the next contributor knows what the gate means and how to run a scan locally.
This is a one-shot setup skill. For per-change feedback after the repo is onboarded, use sonar-review.
Supports both deployment models — the user picks one:
| Mode | When it's right | Host | Key extras |
|---|---|---|---|
| SonarQube server | Self-hosted, on-prem or in own VPC. Enterprise / regulated orgs. | https://sonar.<company>.com (set per-org) |
Project token + host URL |
| SonarCloud | SaaS, hosted by SonarSource. Faster setup, no infra. | https://sonarcloud.io (fixed) |
Project token + organization key |
The choice changes three things: the properties file (SonarCloud needs sonar.organization), the GitHub Actions step (different action), and the secrets the user must add. Everything else is identical.
How to respond
-
Ask which mode if the user hasn't said — it's the first question. One question, not two:
Which Sonar are you using — SonarQube server (self-hosted) or SonarCloud (SaaS at sonarcloud.io)?
If they describe the host URL, infer: anything matching
sonarcloud.io⇒ SonarCloud; anything else ⇒ SonarQube server. Don't ask twice. -
Collect the inputs. Ask for whichever are missing. Cap at two more clarifying questions per turn; pick defaults for the rest and call them out:
Input Required for Default if not given Project key (e.g. myorg_payments-api)both <repo-name>(derive fromgit remote get-url origin)Organization key (SonarCloud only, e.g. my-org)SonarCloud Required — ask if missing SonarQube host URL (e.g. https://sonar.company.com)SonarQube server Required — ask if missing Primary language(s) both Detect from repo (see step 3) CI system both GitHub Actions (emit gitlab-ci/jenkins/azure-pipelinesonly if user names it)Coverage tool both Detect from language (see step 4)
What ships with it
8 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.

sonar-onboard is a skill published in the GitHub repository sananthanarayan/skilldrop (2 stars, last pushed 24d ago), licensed MIT. It adds 157 tokens to every session and 3,455 once invoked, about $0.0008 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.
Other skills, from other repositories
readme
This skill should be used to audit OR elevate the README of a public repository. Trigger with "improve the README", "make the readme high quality", "elevate this readme", "audit the readme", "add badges", "is our README good", or before publishing/releasing a repo. Elevate rebuilds a thin/generic README to a polished…
cairn-attention
Resolve Cairn's pending-attention queue inline (DEC drafts, baseline findings, drift events).
cairn-direction
Spec-tightener + subagent dispatcher. Engage on code-change asks — verbs, bug reports, observations. Pivot-aware on active tasks.
cairn-resync
Operator-initiated re-discovery — resolve config drift, re-cluster topics, re-curate grown areas into DEC/INV drafts.
ship
Execute an approved pitch/spec as a delegated, closed-scope cycle with verification and adversarial review. Invoke it yourself with /ship — a cycle spawns a writer and opens a PR, so it starts when you say so. Enforces the execution playbook: right-size gate, pre-spawn filter, doc-bundle, PR format, review.
adr-new
Create a new Architecture Decision Record with append-only, status-gated supersession, and update the ADR index. Invoke with /adr-new, or let /tdd-author invoke it on approval of an ADR action (this skill stays model-invocable for that reason).
