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 | $0.00048 | $0.03674 |
| Opus 5 | $0.00024 | $0.01837 |
| Sonnet 5 | $0.00010 | $0.00735 |
| Haiku 4.5 | $0.00005 | $0.00367 |
Grade A, and why
appwrite-backend 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 4d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
1. **Official SDK only** — raw Appwrite HTTP (`fetch`, `requests`, `dio`, `package:http`, `curl`) is a violation unless the SDK lacks the endpoint or an isolated, tested `Client.call` works around SDK model parsing. How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Appwrite Development
Route
Load the owner before acting. Unlisted detail = read the owner, never infer.
| Trigger | Owner |
|---|---|
| Any Appwrite CLI/wrapper command, deployment, schema sync, function/site variable operation, or CLI failure — before installing, binding, probing, diagnosing, or mutating | appwrite-cli |
| Production schema/data/ACL/function cutover | production-migrations + CLI owner when CLI participates |
| TablesDB transaction or cross-service consistency | transactions + permissions |
| Permanent account/subject-data erasure across TablesDB, Auth, Storage, provider data, or retained audit evidence | destructive-erasure + transactions |
| Mass row create/update/upsert/delete, transaction-limit pressure, per-row write loop | bulk-operations + transactions when atomic scope spans requests/tables |
Filter by more IDs than the deployed Query.equal() value cap |
chunked-queries |
| Table/column/index design, encryption at rest, auto-increment, timestamp override, CSV import/export | schema-management |
Query shape, select, spatial, time helpers, missing-index suspicion |
query-optimization |
| Counter, array, string, or date field mutated concurrently | atomic-operators |
| Relationship modeling or traversal | relationships |
| List, feed, infinite scroll, or large-offset paging | pagination-performance |
| Slow path, caching, delta sync, bootstrap ordering | performance |
| Bandwidth, execution, or storage cost | cost-optimization |
| Sessions, MFA, SSR auth, JWT, user labels, security settings | authentication |
| OAuth, magic link, email OTP, phone, anonymous, custom token | auth-methods |
| ACL design, lockout, public-leak suspicion | permissions |
| Team, membership, or multi-tenancy | teams |
| Upload, download, preview, transform, bucket config | storage-files |
| Function authoring, handler, runtime, cold start, env vars | functions |
| Function events, schedules, idempotency, binary payloads, CI/CD | functions-advanced |
| Function execution SDK model or response-format parsing failure after remote work starts | functions-advanced |
| Realtime subscription, channel, presence, event filtering | realtime |
| Push, email, or SMS delivery | messaging |
| Outbound event delivery to an external system | webhooks |
| Avatar, initials, QR, flag, favicon | avatars |
429, retry, typed error, timeout, code-zero transport failure, client request burst, partial-sync report |
error-handling + performance |
| Platform ceiling or limit error | limits |
| Country, currency, language, or geo lookup | locale |
| GraphQL endpoint | graphql |
| Appwrite MCP server setup for a coding agent, or Appwrite documentation lookup | mcp-servers |

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.

appwrite-backend is a skill published in the GitHub repository sgaabdu4/hard-eng (5 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 3,674 once invoked, about $0.0002 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.
