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: 1 finding, up to medium
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 →
- medium Data Exfiltration · line 84 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 | $0.00156 | $0.02067 |
| Opus 5 | $0.00078 | $0.01033 |
| Sonnet 5 | $0.00031 | $0.00413 |
| Haiku 4.5 | $0.00016 | $0.00207 |
Grade A, and why
postman-newman-automation 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 11d 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 — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Postman Newman Automation
Generates Newman CLI commands, shell scripts, and Jenkins pipeline configs for running Postman collections in automated environments.
Newman Basics
Newman is Postman's CLI runner. Install with:
npm install -g newman
# Optional HTML reporter:
npm install -g newman-reporter-htmlextra
Core Command Structure
newman run <collection> \
--environment <env-file> \
--globals <globals-file> \
--iteration-count <n> \
--iteration-data <csv-or-json> \
--reporters <reporter-list> \
--reporter-htmlextra-export <output.html> \
--reporter-junit-export <results.xml> \
--timeout-request <ms> \
--delay-request <ms> \
--bail \
--color on
Step 1 — Gather Requirements
Ask or infer from context:
| Parameter | Question |
|---|---|
| Collection source | File path, URL, or Postman API UID? |
| Environment | File path or inline variables? |
| Reporter(s) | CLI only, HTML report, JUnit XML? |
| Fail behavior | Stop on first failure (--bail) or run all? |
| Iterations | Single run or data-driven (CSV/JSON)? |
| Target | Local shell, Jenkins, or both? |
Step 2 — Generate Newman Command
Basic run (local)
newman run collection.json \
--environment environment.json \
--reporters cli,htmlextra \
--reporter-htmlextra-export reports/report.html \
--bail
Run from Postman API (by UID)
newman run "https://api.getpostman.com/collections/<UID>?apikey={{POSTMAN_API_KEY}}" \
--environment environment.json \
--reporters cli,junit \
--reporter-junit-export results/junit.xml
Data-driven run (CSV)
newman run collection.json \
--iteration-data test-data.csv \
--iteration-count 5 \
--reporters cli,htmlextra \
--reporter-htmlextra-export reports/data-driven-report.html
With environment variable overrides (no file needed)
newman run collection.json \
--env-var "base_url=https://staging.api.example.com" \
--env-var "token=abc123" \
--reporters cli
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.

postman-newman-automation is a skill published in the GitHub repository LambdaTest/agent-skills (366 stars, last pushed 1mo ago), licensed MIT. It adds 156 tokens to every session and 2,067 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 2026-08-30.
