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 | $0.00039 | $0.00676 |
| Opus 5.5 | $0.00016 | $0.00270 |
| Sonnet 5.5 | $0.00008 | $0.00135 |
| Haiku 4.5 | $0.00004 | $0.00068 |
Grade A, and why
scheduled-regression-synthetic-monitoring 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.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scheduled Regression and Synthetic Monitoring
Outcome
Create an unattended schedule that runs a saved browser QA route for explicit groups, preserves comparable history and evidence, and delivers bounded notifications for actionable changes.
When to use
Use only after the selected browser suite and its unattended authentication, fixtures, cleanup, evidence, and report behavior have passed manually. Synthetic checks must target an authorized environment.
Discovery and user direction
Inspect the current workflow, goals, metrics, configuration, capabilities, stores, reports, and triggers before proposing changes. Summarize reusable design and gaps, then ask focused questions for unresolved customer choices such as scope, success, approvals, thresholds, ownership, and budgets. Record the answers as customer direction. Installation alone does not approve workflow changes or execution. Default to one small-team workflow; split only for incompatible access or lifecycle boundaries.
Required inputs
Resolve the exact saved route, groups, cadence/calendar and timezone, environment, concurrency and timeout limits, unattended human-decision defaults, retention, notification conditions/destinations, ownership, and pause/escalation policy.
Plan and AgentWorks tools
Reuse the existing validation route; scheduling is configuration, not a duplicate test workflow. Inspect with list_schedules, create or update through current schedule tools, and test with trigger_schedule. Pass route selections and safe human defaults explicitly. API-triggered CI work belongs to the Release/PR Gate.
Knowledge and persistence
Persist every scheduled run and notification receipt with schedule, route, group, build/environment, lifecycle, result, and evidence references. Keep schedule policy in configuration and reusable application facts in KB notes. Never place secret values in messages or reports.
Validation and reporting
Verify one controlled scheduled/triggered run, overlap behavior, timeout/cancellation, cleanup, history, report trends, and notification deduplication. The dashboard shows schedule and route health, environment, latest result, duration, evidence, run history, and notification state. Missing runs, stale data, and notification failures remain visible and cannot imply health.
What ships with it
3 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.

scheduled-regression-synthetic-monitoring is a skill published in the GitHub repository manishiitg/coding-agent-loop (13 stars, last pushed 19d ago), licensed MIT. It adds 39 tokens to every session and 676 once invoked, about $0.0002 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 2026-09-14.
