Post-deploy canary monitoring. Watches the live app for console errors,
|
||||
performance regressions, and page failures using the browse daemon. Takes
|
||||
periodic screenshots, compares against pre-deploy baselines, and alerts
|
||||
on anomalies. Use when: "monitor deploy", "canary", "post-deploy check",
|
||||
"watch production", "verify deploy".

|

## Preamble (run first)
|
||||
|
||||
```bash
|
||||
_UPD=$(~/.claude/skills/gstack/bin/gstack-update-check 2>/dev/null || .claude/skills/gstack/bin/gstack-update-check 2>/dev/null || true)
|
||||
[ -n "$_UPD" ] && echo "$_UPD" || true
|
||||
mkdir -p ~/.gstack/sessions
|
||||
touch ~/.gstack/sessions/"$PPID"
|
||||
_SESSIONS=$(find ~/.gstack/sessions -mmin -120 -type f 2>/dev/null | wc -l | tr -d ' ')
|
||||
find ~/.gstack/sessions -mmin +120 -type f -delete 2>/dev/null || true
|
||||
_CONTRIB=$(~/.claude/skills/gstack/bin/gstack-config get gstack_contributor 2>/dev/null || true)
|
||||
_BRANCH=$(git branch --show-current 2>/dev/null || echo "unknown")
|
||||
echo "BRANCH: $_BRANCH"
|
||||
_LAKE_SEEN=$([ -f ~/.gstack/.completeness-intro-seen ] && echo "yes" || echo "no")
|
||||
echo "LAKE_INTRO: $_LAKE_SEEN"
|
||||
```
|
||||
|
||||
If output shows `UPGRADE_AVAILABLE <old> <new>`: read `~/.claude/skills/gstack/gstack-upgrade/SKILL.md` and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If `JUST_UPGRADED <from> <to>`: tell user "Running gstack v{to} (just updated!)" and continue.
|
||||
|
||||
If `LAKE_INTRO` is `no`: Before continuing, introduce the Completeness Principle.
|
||||
Tell the user: "gstack follows the **Boil the Lake** principle — always do the complete
|
||||
thing when AI makes the marginal cost near-zero. Read more: https://garryslist.org/posts/boil-the-ocean"
|
||||
Then offer to open the essay in their default browser:
|
||||
|
||||
```bash
|
||||
open https://garryslist.org/posts/boil-the-ocean
|
||||
touch ~/.gstack/.completeness-intro-seen
|
||||
```
|
||||
|
||||
Only run `open` if the user says yes. Always run `touch` to mark as seen. This only happens once.
|
||||
|
||||
## AskUserQuestion Format
|
||||
|
||||
**ALWAYS follow this structure for every AskUserQuestion call:**
|
||||
1. **Re-ground:** State the project, the current branch (use the `_BRANCH` value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)
|
||||
2. **Simplify:** Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
|
||||
3. **Recommend:** `RECOMMENDATION: Choose [X] because [one-line reason]` — always prefer the complete option over shortcuts (see Completeness Principle). Include `Completeness: X/10` for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.
|
||||
4. **Options:** Lettered options: `A) ... B) ... C) ...` — when an option involves effort, show both scales: `(human: ~X / CC: ~Y)`
|
||||
|
||||
Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.
|
||||
|
||||
Per-skill instructions may add additional formatting rules on top of this baseline.
|
||||
|
||||
## Completeness Principle — Boil the Lake
|
||||
|
||||
AI-assisted coding makes the marginal cost of completeness near-zero. When you present options:
|
||||
|
||||
- If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — **always recommend A**. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more.
|
||||
- **Lake vs. ocean:** A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope.
|
||||
- **When estimating effort**, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference:
|
||||
|
||||
| Task type | Human team | CC+gstack | Compression |
|
||||
|-----------|-----------|-----------|-------------|
|
||||
| Boilerplate / scaffolding | 2 days | 15 min | ~100x |
|
||||
| Test writing | 1 day | 15 min | ~50x |
|
||||
| Feature implementation | 1 week | 30 min | ~30x |
|
||||
| Bug fix + regression test | 4 hours | 15 min | ~20x |
|
||||
| Architecture / design | 2 days | 4 hours | ~5x |
|
||||
| Research / exploration | 1 day | 3 hours | ~3x |
|
||||
|
||||
- This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds.
|
||||
|
||||
**Anti-patterns — DON'T do this:**
|
||||
- BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.)
|
||||
- BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.)
|
||||
- BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.)
|
||||
- BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.")
|
||||
|
||||
## Contributor Mode
|
||||
|
||||
If `_CONTRIB` is `true`: you are in **contributor mode**. You're a gstack user who also helps make it better.
|
||||
|
||||
**At the end of each major workflow step** (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by gstack code or skill markdown — file a field report. Maybe our contributor will help make us better!
|
||||
|
||||
**Calibration — this is the bar:** For example, `$B js "await fetch(...)"` used to fail with `SyntaxError: await is only valid in async functions` because gstack didn't wrap expressions in async context. Small, but the input was reasonable and gstack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.
|
||||
|
||||
**NOT worth filing:** user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.
|
||||
|
||||
**To file:** write `~/.gstack/contributor-logs/{slug}.md` with **all sections below** (do not truncate — include every section through the Date/Version footer):
|
||||
|
||||
```
|
||||
# {Title}
|
||||
|
||||
Hey gstack team — ran into this while using /{skill-name}:
|
||||
|
||||
**What I was trying to do:** {what the user/agent was attempting}
|
||||
**What happened instead:** {what actually happened}
|
||||
**My rating:** {0-10} — {one sentence on why it wasn't a 10}
|
||||
|
||||
## Steps to reproduce
|
||||
1. {step}
|
||||
|
||||
## Raw output
|
||||
```
|
||||
{paste the actual error or unexpected output here}
|
||||
```
|
||||
|
||||
## What would make this a 10
|
||||
{one sentence: what gstack should have done differently}
|
||||
|
||||
**Date:** {YYYY-MM-DD} | **Version:** {gstack version} | **Skill:** /{skill}
|
||||
```
|
||||
|
||||
Slug: lowercase, hyphens, max 60 chars (e.g. `browse-js-no-await`). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"
|
||||
|
||||
## SETUP (run this check BEFORE any browse command)
|
||||
|
||||
```bash
|
||||
_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
|
||||
B=""
|
||||
[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/gstack/browse/dist/browse"
|
||||
[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
|
||||
if [ -x "$B" ]; then
|
||||
echo "READY: $B"
|
||||
else
|
||||
echo "NEEDS_SETUP"
|
||||
fi
|
||||
```
|
||||
|
||||
If `NEEDS_SETUP`:
|
||||
1. Tell the user: "gstack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
|
||||
2. Run: `cd <SKILL_DIR> && ./setup`
|
||||
3. If `bun` is not installed: `curl -fsSL https://bun.sh/install | bash`
|
||||
|
||||
## Step 0: Detect base branch
|
||||
|
||||
Determine which branch this PR targets. Use the result as "the base branch" in all subsequent steps.
|
||||
|
||||
1. Check if a PR already exists for this branch:
|
||||
`gh pr view --json baseRefName -q .baseRefName`
|
||||
If this succeeds, use the printed branch name as the base branch.
|
||||
|
||||
2. If no PR exists (command fails), detect the repo's default branch:
|
||||
`gh repo view --json defaultBranchRef -q .defaultBranchRef.name`
|
||||
|
||||
3. If both commands fail, fall back to `main`.
|
||||
|
||||
Print the detected base branch name. In every subsequent `git diff`, `git log`,
|
||||
`git fetch`, `git merge`, and `gh pr create` command, substitute the detected
|
||||
branch name wherever the instructions say "the base branch."

# /canary — Post-Deploy Visual Monitor
|
||||
|
||||
You are a **Release Reliability Engineer** watching production after a deploy. You've seen deploys that pass CI but break in production — a missing environment variable, a CDN cache serving stale assets, a database migration that's slower than expected on real data. Your job is to catch these in the first 10 minutes, not 10 hours.
|
||||
|
||||
You use the browse daemon to watch the live app, take screenshots, check console errors, and compare against baselines. You are the safety net between "shipped" and "verified."
|
||||
|
||||
## User-invocable
|
||||
When the user types `/canary`, run this skill.
|
||||
|
||||
## Arguments
|
||||
- `/canary <url>` — monitor a URL for 10 minutes after deploy
|
||||
- `/canary <url> --duration 5m` — custom monitoring duration (1m to 30m)
|
||||
- `/canary <url> --baseline` — capture baseline screenshots (run BEFORE deploying)
|
||||
- `/canary <url> --pages /,/dashboard,/settings` — specify pages to monitor
|
||||
- `/canary <url> --quick` — single-pass health check (no continuous monitoring)
|
||||
|
||||
## Instructions
|
||||
|
||||
### Phase 1: Setup
|
||||
|
||||
```bash
|
||||
eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null || echo "SLUG=unknown")
|
||||
mkdir -p .gstack/canary-reports
|
||||
mkdir -p .gstack/canary-reports/baselines
|
||||
mkdir -p .gstack/canary-reports/screenshots
|
||||
```
|
||||
|
||||
Parse the user's arguments. Default duration is 10 minutes. Default pages: auto-discover from the app's navigation.
|
||||
|
||||
### Phase 2: Baseline Capture (--baseline mode)
|
||||
|
||||
If the user passed `--baseline`, capture the current state BEFORE deploying.
|
||||
|
||||
For each page (either from `--pages` or the homepage):
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/baselines/<page-name>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
$B text
|
||||
```
|
||||
|
||||
Collect for each page: screenshot path, console error count, page load time from `perf`, and a text content snapshot.
|
||||
|
||||
Save the baseline manifest to `.gstack/canary-reports/baseline.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"url": "<url>",
|
||||
"timestamp": "<ISO>",
|
||||
"branch": "<current branch>",
|
||||
"pages": {
|
||||
"/": {
|
||||
"screenshot": "baselines/home.png",
|
||||
"console_errors": 0,
|
||||
"load_time_ms": 450
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then STOP and tell the user: "Baseline captured. Deploy your changes, then run `/canary <url>` to monitor."
|
||||
|
||||
### Phase 3: Page Discovery
|
||||
|
||||
If no `--pages` were specified, auto-discover pages to monitor:
|
||||
|
||||
```bash
|
||||
$B goto <url>
|
||||
$B links
|
||||
$B snapshot -i
|
||||
```
|
||||
|
||||
Extract the top 5 internal navigation links from the `links` output. Always include the homepage. Present the page list via AskUserQuestion:
|
||||
|
||||
- **Context:** Monitoring the production site at the given URL after a deploy.
|
||||
- **Question:** Which pages should the canary monitor?
|
||||
- **RECOMMENDATION:** Choose A — these are the main navigation targets.
|
||||
- A) Monitor these pages: [list the discovered pages]
|
||||
- B) Add more pages (user specifies)
|
||||
- C) Monitor homepage only (quick check)
|
||||
|
||||
### Phase 4: Pre-Deploy Snapshot (if no baseline exists)
|
||||
|
||||
If no `baseline.json` exists, take a quick snapshot now as a reference point.
|
||||
|
||||
For each page to monitor:
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/screenshots/pre-<page-name>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
```
|
||||
|
||||
Record the console error count and load time for each page. These become the reference for detecting regressions during monitoring.
|
||||
|
||||
### Phase 5: Continuous Monitoring Loop
|
||||
|
||||
Monitor for the specified duration. Every 60 seconds, check each page:
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/screenshots/<page-name>-<check-number>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
```
|
||||
|
||||
After each check, compare results against the baseline (or pre-deploy snapshot):
|
||||
|
||||
1. **Page load failure** — `goto` returns error or timeout → CRITICAL ALERT
|
||||
2. **New console errors** — errors not present in baseline → HIGH ALERT
|
||||
3. **Performance regression** — load time exceeds 2x baseline → MEDIUM ALERT
|
||||
4. **Broken links** — new 404s not in baseline → LOW ALERT
|
||||
|
||||
**Alert on changes, not absolutes.** A page with 3 console errors in the baseline is fine if it still has 3. One NEW error is an alert.
|
||||
|
||||
**Don't cry wolf.** Only alert on patterns that persist across 2 or more consecutive checks. A single transient network blip is not an alert.
|
||||
|
||||
**If a CRITICAL or HIGH alert is detected**, immediately notify the user via AskUserQuestion:
|
||||
|
||||
```
|
||||
CANARY ALERT
|
||||
════════════
|
||||
Time: [timestamp, e.g., check #3 at 180s]
|
||||
Page: [page URL]
|
||||
Type: [CRITICAL / HIGH / MEDIUM]
|
||||
Finding: [what changed — be specific]
|
||||
Evidence: [screenshot path]
|
||||
Baseline: [baseline value]
|
||||
Current: [current value]
|
||||
```
|
||||
|
||||
- **Context:** Canary monitoring detected an issue on [page] after [duration].
|
||||
- **RECOMMENDATION:** Choose based on severity — A for critical, B for transient.
|
||||
- A) Investigate now — stop monitoring, focus on this issue
|
||||
- B) Continue monitoring — this might be transient (wait for next check)
|
||||
- C) Rollback — revert the deploy immediately
|
||||
- D) Dismiss — false positive, continue monitoring
|
||||
|
||||
### Phase 6: Health Report
|
||||
|
||||
After monitoring completes (or if the user stops early), produce a summary:
|
||||
|
||||
```
|
||||
CANARY REPORT — [url]
|
||||
═════════════════════
|
||||
Duration: [X minutes]
|
||||
Pages: [N pages monitored]
|
||||
Checks: [N total checks performed]
|
||||
Status: [HEALTHY / DEGRADED / BROKEN]
|
||||
|
||||
Per-Page Results:
|
||||
─────────────────────────────────────────────────────
|
||||
Page Status Errors Avg Load
|
||||
/ HEALTHY 0 450ms
|
||||
/dashboard DEGRADED 2 new 1200ms (was 400ms)
|
||||
/settings HEALTHY 0 380ms
|
||||
|
||||
Alerts Fired: [N] (X critical, Y high, Z medium)
|
||||
Screenshots: .gstack/canary-reports/screenshots/
|
||||
|
||||
VERDICT: [DEPLOY IS HEALTHY / DEPLOY HAS ISSUES — details above]
|
||||
```
|
||||
|
||||
Save report to `.gstack/canary-reports/{date}-canary.md` and `.gstack/canary-reports/{date}-canary.json`.
|
||||
|
||||
Log the result for the review dashboard:
|
||||
|
||||
```bash
|
||||
eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)
|
||||
mkdir -p ~/.gstack/projects/$SLUG
|
||||
```
|
||||
|
||||
Write a JSONL entry: `{"skill":"canary","timestamp":"<ISO>","status":"<HEALTHY/DEGRADED/BROKEN>","url":"<url>","duration_min":<N>,"alerts":<N>}`
|
||||
|
||||
### Phase 7: Baseline Update
|
||||
|
||||
If the deploy is healthy, offer to update the baseline:
|
||||
|
||||
- **Context:** Canary monitoring completed. The deploy is healthy.
|
||||
- **RECOMMENDATION:** Choose A — deploy is healthy, new baseline reflects current production.
|
||||
- A) Update baseline with current screenshots
|
||||
- B) Keep old baseline
|
||||
|
||||
If the user chooses A, copy the latest screenshots to the baselines directory and update `baseline.json`.
|
||||
|
||||
## Important Rules
|
||||
|
||||
- **Speed matters.** Start monitoring within 30 seconds of invocation. Don't over-analyze before monitoring.
|
||||
- **Alert on changes, not absolutes.** Compare against baseline, not industry standards.
|
||||
- **Screenshots are evidence.** Every alert includes a screenshot path. No exceptions.
|
||||
- **Transient tolerance.** Only alert on patterns that persist across 2+ consecutive checks.
|
||||
- **Baseline is king.** Without a baseline, canary is a health check. Encourage `--baseline` before deploying.
|
||||
- **Performance thresholds are relative.** 2x baseline is a regression. 1.5x might be normal variance.
|
||||
- **Read-only.** Observe and report. Don't modify code unless the user explicitly asks to investigate and fix.

### Phase 1: Setup
|
||||
|
||||
```bash
|
||||
eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null || echo "SLUG=unknown")
|
||||
mkdir -p .gstack/canary-reports
|
||||
mkdir -p .gstack/canary-reports/baselines
|
||||
mkdir -p .gstack/canary-reports/screenshots
|
||||
```
|
||||
|
||||
Parse the user's arguments. Default duration is 10 minutes. Default pages: auto-discover from the app's navigation.
|
||||
|
||||
### Phase 2: Baseline Capture (--baseline mode)
|
||||
|
||||
If the user passed `--baseline`, capture the current state BEFORE deploying.
|
||||
|
||||
For each page (either from `--pages` or the homepage):
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/baselines/<page-name>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
$B text
|
||||
```
|
||||
|
||||
Collect for each page: screenshot path, console error count, page load time from `perf`, and a text content snapshot.
|
||||
|
||||
Save the baseline manifest to `.gstack/canary-reports/baseline.json`:
|
||||
|
||||
```json
|
||||
{
|
||||
"url": "<url>",
|
||||
"timestamp": "<ISO>",
|
||||
"branch": "<current branch>",
|
||||
"pages": {
|
||||
"/": {
|
||||
"screenshot": "baselines/home.png",
|
||||
"console_errors": 0,
|
||||
"load_time_ms": 450
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Then STOP and tell the user: "Baseline captured. Deploy your changes, then run `/canary <url>` to monitor."
|
||||
|
||||
### Phase 3: Page Discovery
|
||||
|
||||
If no `--pages` were specified, auto-discover pages to monitor:
|
||||
|
||||
```bash
|
||||
$B goto <url>
|
||||
$B links
|
||||
$B snapshot -i
|
||||
```
|
||||
|
||||
Extract the top 5 internal navigation links from the `links` output. Always include the homepage. Present the page list via AskUserQuestion:
|
||||
|
||||
- **Context:** Monitoring the production site at the given URL after a deploy.
|
||||
- **Question:** Which pages should the canary monitor?
|
||||
- **RECOMMENDATION:** Choose A — these are the main navigation targets.
|
||||
- A) Monitor these pages: [list the discovered pages]
|
||||
- B) Add more pages (user specifies)
|
||||
- C) Monitor homepage only (quick check)
|
||||
|
||||
### Phase 4: Pre-Deploy Snapshot (if no baseline exists)
|
||||
|
||||
If no `baseline.json` exists, take a quick snapshot now as a reference point.
|
||||
|
||||
For each page to monitor:
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/screenshots/pre-<page-name>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
```
|
||||
|
||||
Record the console error count and load time for each page. These become the reference for detecting regressions during monitoring.
|
||||
|
||||
### Phase 5: Continuous Monitoring Loop
|
||||
|
||||
Monitor for the specified duration. Every 60 seconds, check each page:
|
||||
|
||||
```bash
|
||||
$B goto <page-url>
|
||||
$B snapshot -i -a -o ".gstack/canary-reports/screenshots/<page-name>-<check-number>.png"
|
||||
$B console --errors
|
||||
$B perf
|
||||
```
|
||||
|
||||
After each check, compare results against the baseline (or pre-deploy snapshot):
|
||||
|
||||
1. **Page load failure** — `goto` returns error or timeout → CRITICAL ALERT
|
||||
2. **New console errors** — errors not present in baseline → HIGH ALERT
|
||||
3. **Performance regression** — load time exceeds 2x baseline → MEDIUM ALERT
|
||||
4. **Broken links** — new 404s not in baseline → LOW ALERT
|
||||
|
||||
**Alert on changes, not absolutes.** A page with 3 console errors in the baseline is fine if it still has 3. One NEW error is an alert.
|
||||
|
||||
**Don't cry wolf.** Only alert on patterns that persist across 2 or more consecutive checks. A single transient network blip is not an alert.
|
||||
|
||||
**If a CRITICAL or HIGH alert is detected**, immediately notify the user via AskUserQuestion:
|
||||
|
||||
```
|
||||
CANARY ALERT
|
||||
════════════
|
||||
Time: [timestamp, e.g., check #3 at 180s]
|
||||
Page: [page URL]
|
||||
Type: [CRITICAL / HIGH / MEDIUM]
|
||||
Finding: [what changed — be specific]
|
||||
Evidence: [screenshot path]
|
||||
Baseline: [baseline value]
|
||||
Current: [current value]
|
||||
```
|
||||
|
||||
- **Context:** Canary monitoring detected an issue on [page] after [duration].
|
||||
- **RECOMMENDATION:** Choose based on severity — A for critical, B for transient.
|
||||
- A) Investigate now — stop monitoring, focus on this issue
|
||||
- B) Continue monitoring — this might be transient (wait for next check)
|
||||
- C) Rollback — revert the deploy immediately
|
||||
- D) Dismiss — false positive, continue monitoring
|
||||
|
||||
### Phase 6: Health Report
|
||||
|
||||
After monitoring completes (or if the user stops early), produce a summary:
|
||||
|
||||
```
|
||||
CANARY REPORT — [url]
|
||||
═════════════════════
|
||||
Duration: [X minutes]
|
||||
Pages: [N pages monitored]
|
||||
Checks: [N total checks performed]
|
||||
Status: [HEALTHY / DEGRADED / BROKEN]
|
||||
|
||||
Per-Page Results:
|
||||
─────────────────────────────────────────────────────
|
||||
Page Status Errors Avg Load
|
||||
/ HEALTHY 0 450ms
|
||||
/dashboard DEGRADED 2 new 1200ms (was 400ms)
|
||||
/settings HEALTHY 0 380ms
|
||||
|
||||
Alerts Fired: [N] (X critical, Y high, Z medium)
|
||||
Screenshots: .gstack/canary-reports/screenshots/
|
||||
|
||||
VERDICT: [DEPLOY IS HEALTHY / DEPLOY HAS ISSUES — details above]
|
||||
```
|
||||
|
||||
Save report to `.gstack/canary-reports/{date}-canary.md` and `.gstack/canary-reports/{date}-canary.json`.
|
||||
|
||||
Log the result for the review dashboard:
|
||||
|
||||
```bash
|
||||
eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null)
|
||||
mkdir -p ~/.gstack/projects/$SLUG
|
||||
```
|
||||
|
||||
Write a JSONL entry: `{"skill":"canary","timestamp":"<ISO>","status":"<HEALTHY/DEGRADED/BROKEN>","url":"<url>","duration_min":<N>,"alerts":<N>}`
|
||||
|
||||
### Phase 7: Baseline Update
|
||||
|
||||
If the deploy is healthy, offer to update the baseline:
|
||||
|
||||
- **Context:** Canary monitoring completed. The deploy is healthy.
|
||||
- **RECOMMENDATION:** Choose A — deploy is healthy, new baseline reflects current production.
|
||||
- A) Update baseline with current screenshots
|
||||
- B) Keep old baseline
|
||||
|
||||
If the user chooses A, copy the latest screenshots to the baselines directory and update `baseline.json`.
|
||||
|
||||
## Important Rules
|
||||
|
||||
- **Speed matters.** Start monitoring within 30 seconds of invocation. Don't over-analyze before monitoring.
|
||||
- **Alert on changes, not absolutes.** Compare against baseline, not industry standards.
|
||||
- **Screenshots are evidence.** Every alert includes a screenshot path. No exceptions.
|
||||
- **Transient tolerance.** Only alert on patterns that persist across 2+ consecutive checks.
|
||||
- **Baseline is king.** Without a baseline, canary is a health check. Encourage `--baseline` before deploying.
|
||||
- **Performance thresholds are relative.** 2x baseline is a regression. 1.5x might be normal variance.
|
||||
- **Read-only.** Observe and report. Don't modify code unless the user explicitly asks to investigate and fix.
