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: 2 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 →
- high Privilege Escalation · line 530 Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
- medium Data Exfiltration · line 211 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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 | $0.00147 | $0.05698 |
| Opus 5.5 | $0.00059 | $0.02279 |
| Sonnet 5.5 | $0.00029 | $0.01140 |
| Haiku 4.5 | $0.00015 | $0.00570 |
Grade A, and why
airflow-plugins scanned grade A with 1 finding 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.

Airflow 3 Plugins
Airflow 3 plugins let you embed FastAPI apps, React UIs, middleware, macros, operator buttons, and custom timetables directly into the Airflow process. No sidecar, no extra server.
CRITICAL: Plugin components (fastapi_apps, react_apps, external_views) require Airflow 3.1+. NEVER import
flask,flask_appbuilder, or useappbuilder_views/flask_blueprints— these are Airflow 2 patterns and will not work in Airflow 3. If existing code uses them, rewrite the entire registration block using FastAPI.Security: FastAPI plugin endpoints are not automatically protected by Airflow auth. If your endpoints need to be private, implement authentication explicitly using FastAPI's security utilities.
Restart required: Changes to Python plugin files require restarting the API server. Static file changes (HTML, JS, CSS) are picked up immediately. Set
AIRFLOW__CORE__LAZY_LOAD_PLUGINS=Falseduring development to load plugins at startup rather than lazily.Relative paths always: In
external_views,hrefmust have no leading slash. In HTML and JavaScript, use relative paths for all assets andfetch()calls. Absolute paths break behind reverse proxies.
Before writing any code, verify
- Am I using
fastapi_apps/ FastAPI — notappbuilder_views/ Flask? - Are all HTML/JS asset paths and
fetch()calls relative (no leading slash)? - Are all synchronous SDK or SQLAlchemy calls wrapped in
asyncio.to_thread()? - Do the
static/andassets/directories exist before the FastAPI app mounts them? - If the endpoint must be private, did I add explicit FastAPI authentication?
Step 1: Choose plugin components
A single plugin class can register multiple component types at once.
| Component | What it does | Field |
|---|---|---|
| Custom API endpoints | FastAPI app mounted in Airflow process | fastapi_apps |
| Nav / page link | Embeds a URL as an iframe or links out | external_views |
| React component | Custom React app embedded in Airflow UI | react_apps |
| API middleware | Intercepts all Airflow API requests/responses | fastapi_root_middlewares |
| Jinja macros | Reusable Python functions in DAG templates | macros |
| Task instance button | Extra link button in task Detail view | operator_extra_links / global_operator_extra_links |
| Custom timetable | Custom scheduling logic | timetables |
| Event hooks | Listener callbacks for Airflow events | listeners |
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.

airflow-plugins is a skill published in the GitHub repository astronomer/agents (454 stars, last pushed 4d ago), licensed Apache-2.0. It adds 147 tokens to every session and 5,698 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
