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 | $0.00024 | $0.01603 |
| Opus 5 | $0.00012 | $0.00801 |
| Sonnet 5 | $0.00005 | $0.00321 |
| Haiku 4.5 | $0.00002 | $0.00160 |
Grade A, and why
webhook-subscriptions scanned grade A with 1 finding 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 202 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kheish Compatibility
This skill is repo-local and stays inactive until explicitly activated.
When the original instructions refer to legacy tool names, use these Kheish mappings:
terminal=>bashweb_extract=>web_fetch, plusweb_searchwhen discovery is neededsearch_files=>grep_searchandglob_searchbrowser_*tools require a browser-capable surfaced tool or MCP; if none is available, use the closest available surface and say so explicitly
When the instructions mention local helper files, resolve them from ${KHEISH_SKILL_DIR}.
Kheish does not currently ship a dedicated webhook subscription CLI. In the examples below,
webhook-manager and gateway-manager are placeholders for your deployment tooling around
daemon connector config, ingress routing, and lifecycle management.
Webhook Subscriptions
Create dynamic webhook subscriptions so external services (GitHub, GitLab, Stripe, CI/CD, IoT sensors, monitoring tools) can trigger Kheish agent runs by POSTing events to a URL.
Setup (Required First)
The webhook platform must be enabled before subscriptions can be created. Check with:
webhook-manager list
If it says "Webhook platform is not enabled", set it up:
Option 1: Setup wizard
gateway-manager setup
Follow the prompts to enable webhooks, set the port, and set a global HMAC secret.
Option 2: Manual config
Add to ~/.kheish/config.yaml:
platforms:
webhook:
enabled: true
extra:
host: "0.0.0.0"
port: 8644
secret: "generate-a-strong-secret-here"
Option 3: Environment variables
Add to ~/.kheish/.env:
WEBHOOK_ENABLED=true
WEBHOOK_PORT=8644
WEBHOOK_SECRET=generate-a-strong-secret-here
After configuration, start (or restart) the gateway:
gateway-manager run
# Or if using systemd:
systemctl --user restart kheish-daemon
Verify it's running:
curl http://localhost:8644/health
Commands
All management is via the webhook-manager CLI command:
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.

webhook-subscriptions is a skill published in the GitHub repository graniet/kheish (227 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 24 tokens to every session and 1,603 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
