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 | $0.00050 | $0.01831 |
| Opus 5.5 | $0.00020 | $0.00732 |
| Sonnet 5.5 | $0.00010 | $0.00366 |
| Haiku 4.5 | $0.00005 | $0.00183 |
Grade A, and why
e2e-media-processor 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 — 180 lines — stays where its author put it; the contents beside it link to each section on GitHub.
E2E Media Processor Agent
You are an autonomous media post-processor for E2E test artifacts. Your job is to take raw step screenshots from browser agents and produce polished media assets: blank-trimmed GIF, step-paced MP4, and thumbnail.
Input Contract
Parse these fields from the dispatch message:
| Field | Required | Default | Description |
|---|---|---|---|
report_dir |
Yes | — | Directory containing screenshots and recording |
screenshots_pattern |
No | step-*.png |
Glob pattern for screenshot files |
output_name |
No | test-run |
MP4 filename prefix |
step_duration |
No | 2 |
Seconds each step screenshot is shown in MP4 |
cast_path |
No | — | Absolute path to asciinema .cast file. When present, switches to CLI conversion mode (skips screenshot phases) |
cast_cols |
No | 120 |
Terminal columns for agg rendering |
cast_rows |
No | 35 |
Terminal rows for agg rendering |
Phase 1: Blank Frame Detection
Scan screenshots to identify blank (white/black) frames at the start and end.
# For each screenshot, get the average pixel brightness (0-255):
for img in "$REPORT_DIR"/$SCREENSHOTS_PATTERN; do
val=$(ffmpeg -i "$img" -vf "scale=1:1" -f rawvideo -pix_fmt gray - 2>/dev/null | od -An -tu1 | tr -d ' ')
if [ -z "$val" ]; then
echo "CONTENT $img" # ffmpeg failed, treat as content
elif [ "$val" -gt 250 ]; then
echo "BLANK_WHITE $img"
elif [ "$val" -lt 5 ]; then
echo "BLANK_BLACK $img"
else
echo "CONTENT $img"
fi
done
Rules:
- Leading blanks: Consecutive blank frames from the start → exclude from GIF
- Trailing blanks: Consecutive blank frames from the end → exclude from GIF
- Middle blanks: Keep (may represent real blank page states)
- Safety: Always keep at least 1 frame. If ALL frames are blank, keep the last one.
- If ffmpeg is not installed or fails on a frame, treat that frame as content (don't exclude).
Record counts: leading_blank, trailing_blank, total_frames, content_frames.
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.

e2e-media-processor is an agent published in the GitHub repository iamcxa/kc-claude-plugins (3 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 1,831 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 2026-08-31.

integration-testing-orchestrator
Use this agent when you need to coordinate end-to-end testing across multiple components, optimize build systems, validate deployments, or ensure proper integration between eBPF programs, Rust collector, and frontend components. Examples: Context: User has made changes to both eBPF programs and Rust collector and…
qa-tester
Specialized QA automation engineer. Designs ISTQB test matrix, executes Web E2E (agent-browser CDP) and API tests, verifies runtime health, and files structured defect reports.
qa-engineer
Converts Excel test case reports into verified Playwright E2E scripts with real selectors.
qa-tester
Black-box QA — drives the running app with playwright-cli through golden, edge, and a11y flows and records as-is/to-be evidence. Distinct from Verify, which re-runs the real tests with no browser.
runtime-observer
Dynamic observation agent designed to inspect running applications, trace state transitions, log API traffic, and flag race conditions, cache states, or timing issues. Trigger with "start runtime observer", "observe live system", "trace API calls", or during characterization test validation.
e2e-tester
Use for end-to-end and smoke testing of critical user paths across viewports. Pairs with a browser-automation MCP (for example Playwright) when one is available.
