What it does
Regression Alert is an agent skill from hoangsonww/Claude-Code-Agent-Monitor. Compare this period's reliability against the prior period using Agent Monitor data — error rate (APIError/total) and tool-failure rate (PreToolUse→PostToolUse gap) — flag any regression where reliability got worse, and optionally wire a persistent alert rule so the dashboard catches the next regression automatically. Use when checking whether reliability degraded.
Its SKILL.md is about 900 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in DevOps & Cloud, covering Monitoring and alerting. The repository describes itself as: 🚀 A real-time monitoring dashboard for Claude Code & Codex, built with SQLite3, Node.js, Express, React, Vite, TailwindCSS, & WebSockets. It tracks sessions, agent activity… The licence is MIT.
When your agent uses it
- Checking whether reliability degraded
- Tasks that involve Monitoring and alerting
Example prompts
- “/regression-alert”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit a06db03. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Regression Alert loads about 903 tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 438 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- regression-alert
- description
- Compare this period's reliability against the prior period using Agent Monitor data — error rate (APIError/total) and tool-failure rate (PreToolUse→PostToolUse gap) — flag any regression where reliability got worse, and optionally wire a persistent alert rule so the dashboard catches the next regression automatically. Use when checking whether reliability degraded.
Regression Alert
Detect whether Claude Code reliability is getting worse period-over-period, and
optionally arm an alert so it never has to be checked by hand again. Scope is
reliability/failures only — for cache/cost/compaction drift, use ccam-insights'
regression-watch instead.
Input
The user provides: $ARGUMENTS
This may be:
- empty or "all" — check error rate and tool-failure rate (default)
- "errors" — APIError-rate regression only
- "tools" — tool-failure-rate regression only
- a window like "7 vs 7" or "30 vs 30" — recent vs baseline window sizes (default: last 7 days vs the prior 7)
- "arm" — after reporting, also create an alert rule via
POST /api/alerts/rules(only on explicit request)
Data Sources
| Endpoint | Returns |
|---|---|
GET /api/analytics | daily_events (365d), daily_sessions (365d), event_types — split into recent vs baseline windows to compute per-window failure rates |
GET /api/events?session_id=X | Per-session stream — localize a regression to the sessions driving it |
GET /api/alerts/rules | Existing alert rules — check whether a matching reliability rule already exists before arming a new one |
POST /api/alerts/rules | Create a new alert rule (only when the user says "arm") |
Report Sections
1. Windowing
Split history into a recent window (newer) and a baseline window (the equal-length period just before it). Default: recent = last 7 days, baseline = the prior 7. Use daily_events/daily_sessions to bucket counts by day.
2. Error-Rate Regression
- Per window:
error rate = APIError count / total events. - Compare recent vs baseline. Flag if recent is higher. Report absolute change (pp) and relative change (%), plus the recent sessions contributing the most
APIErrorevents.
3. Tool-Failure-Rate Regression
- Per window:
tool-failure rate = (PreToolUse − PostToolUse) / PreToolUse. - Compare recent vs baseline. Flag a rising rate as a reliability regression. Name the tools whose gap grew most.
Show full SKILL.md (170 more words)Show less
4. Verdict
Roll up which rates regressed, rank by relative worsening, and name the most likely driver.
5. Optional — Arm an Alert
Only if the user passed "arm". First GET /api/alerts/rules to avoid duplicates. Then POST /api/alerts/rules with a rule that fires when the regressed metric crosses a threshold near the recent value (e.g., error rate > recent rate). Echo the created rule back; do not create webhooks or fire alerts.
Output
- A Markdown table: metric | baseline | recent | Δ (pp) | Δ (%) | direction (▲ worse / ▼ better) | verdict.
- Tag each metric 🔴 (clear regression), 🟡 (within noise), or 🟢 (improved).
- Rates as percentages to 2 decimals; any currency in USD to 4 decimals.
- List the specific session IDs that contributed most to any regression.
- End with the single highest-priority regression and a concrete next step (and, if armed, the new rule's id/threshold).
- Read-only except the explicit "arm" path, which is the only write. Never mutate alert rules otherwise. If
curlcannot reachhttp://localhost:4820, tell the user to start the dashboard withnpm startfrom the repo root.

When should I use Regression Alert?
Regression Alert fits situations like: checking whether reliability degraded; tasks that involve Monitoring and alerting.
How do I install Regression Alert in Claude Code?
Run `npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill regression-alert -a claude-code`. Or copy the skill folder (plugins/ccam-quality/skills/regression-alert in hoangsonww/Claude-Code-Agent-Monitor) into .claude/skills/regression-alert in your project. Claude Code loads it when a task matches its description.
How do I install Regression Alert in Codex?

Or copy the skill folder (plugins/ccam-quality/skills/regression-alert in hoangsonww/Claude-Code-Agent-Monitor) into .agents/skills/regression-alert in your project. Codex loads it when a task matches its description.
Can I use Regression Alert in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hoangsonww/Claude-Code-Agent-Monitor --skill regression-alert -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/regression-alert, .gemini/skills/regression-alert, .github/skills/regression-alert and .opencode/skills/regression-alert in your project.
What does Regression Alert need to run?
Going by SKILL.md and its folder, Regression Alert needs the command-line tools its instructions call (npm).
Does Regression Alert access the network?
SKILL.md contains no URLs. Its commands use npm, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Is Regression Alert safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Regression Alert use?
Regression Alert is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Regression Alert use?
About 903 tokens (SKILL.md is roughly 3.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Regression Alert?
