srtd-dev

srtd-dev is a skill for Claude Code from t1mmen/srtd. It costs 46 tokens per session (2,181 once invoked), scanned A, original, MIT.

A development guide for working on SRTD itself, a command-line tool that live-reloads SQL templates into local Supabase databases. It covers the codebase’s architecture, commands, and main files.

In plain words
What is it for?
Use it when adding CLI options, changing template processing or file watching, updating configuration, fixing database behaviour, modifying migration output, or writing and running tests.
Why use it?
It helps contributors locate the right part of the code and follow the project’s one-way flow from file changes through processing and state tracking to database output.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { setupCommandTestSpies, createMockUiModule } from '../helpers/testUtils.js';.

Good fit Use it when adding CLI options, changing template processing or file watching, updating configuration, fixing database behaviour, modifying migration output, or writing and running tests.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

srtd-dev 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.

SRTD Development Skill

Expert guidance for working with the SRTD codebase - a CLI tool for live-reloading SQL templates into Supabase local databases.

Quick Reference

Key Commands

npm test                           # Run all tests
npx vitest run -t "pattern"        # Run specific test
npm run typecheck                  # Type check
npm run lint                       # Biome lint + fix
npm start -- watch                 # Run watch command
npm run supabase:start             # Start test database

Key Files by Task

Task Primary Files
Add CLI option src/commands/{command}.ts, src/cli.ts
Modify template processing src/services/Orchestrator.ts
Change state tracking src/services/StateService.ts
Fix database issues src/services/DatabaseService.ts
Modify migration output src/services/MigrationBuilder.ts
Change file watching src/services/FileSystemService.ts
Update config src/utils/config.ts, src/types.ts

Architecture Mental Model

Unidirectional flow - data flows one direction through the system:

File Change → FileSystemService → Orchestrator → StateService
                                       ↓
                              DatabaseService / MigrationBuilder
                                       ↓
                              StateService (update) → Event Emission

Service Boundaries (Critical)

FileSystemService owns:

  • Template discovery (glob matching)
  • File watching (Chokidar, 100ms debounce)
  • File I/O (read, write, rename)
  • Hash computation (MD5)

StateService owns:

  • All state mutations (single source of truth)
  • Build log persistence (.buildlog.json, .buildlog.local.json)
  • State machine transitions (UNSEEN → CHANGED → APPLIED/BUILT → SYNCED)
  • Hash comparison for change detection

DatabaseService owns:

  • Connection pooling (pg.Pool, max 10 connections)
  • Retry logic (3 attempts, exponential backoff)
  • Error categorization (CONNECTION_ERROR, SYNTAX_ERROR, etc.)
  • Transaction management (BEGIN/COMMIT/ROLLBACK)
  • Advisory locks per template

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.

srtd-dev is a skill published in the GitHub repository t1mmen/srtd (105 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 2,181 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 2026-08-30.
