AGENTS.md

MiHashport-Backend AGENTS.md is an instructions file for Codex, OpenCode from MiHashport/MiHashport-Backend. It costs 667 tokens per session, scanned A, original, MIT.

Contribution instructions for MiHashport Backend, a TypeScript server built with NestJS, PostgreSQL, and Stellar blockchain tools. It explains the repository structure, commands, and rules for making changes.

In plain words
What is it for?
Use it when fixing issues or adding features in the backend, especially within domain modules, database migrations, configuration, tests, and documentation.
Why use it?
It gives coding agents the project context needed to place code correctly and follow the repository's build, test, formatting, commit, and pull-request requirements.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is MiHashport/MiHashport-Backend's own configuration. It tells Codex and OpenCode how to work on MiHashport-Backend itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything MiHashport-Backend configures →

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

MiHashport-Backend AGENTS.md 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 9d 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.

Repo context

  • Stack: NestJS 11, TypeScript (strict mode), TypeORM + PostgreSQL, @stellar/stellar-sdk (Horizon + Soroban RPC), Jest.
  • Build: npm install then npm run build.
  • Run (dev): npm run start:dev (requires a .env — copy .env.example).
  • Test: npm run test (unit tests, Jest, colocated as *.spec.ts).
  • Lint/format: npm run lint, npm run format.
  • Key directories:
    • src/modules/<domain>/ — one folder per domain (users, wallet, stellar, contracts, whatsapp, health), each with its own module, controller, service, dto/, and entities/.
    • src/config/ — typed, Joi-validated configuration (ConfigModule).
    • src/database/ — TypeORM data source and migrations.
    • src/common/ — global filters/interceptors.
    • docs/PLAN.md — the phased roadmap; issues are derived from it.

Rules for contributions

  • Address each issue in its own commit.
  • The PR description must include Closes #<issue> for every issue the PR addresses.
  • Commit messages must be single-line only (no multi-paragraph bodies).
  • Do not add a Co-authored-by line to commits.
  • Keep the implementation minimal and focused on the issue at hand — do not bundle unrelated fixes or refactors into the same PR.
  • Read the surrounding code in the domain folder you're touching before writing anything; integrate with the existing module/controller/service/DTO structure rather than introducing a new pattern.
  • Avoid over-engineering. Don't build abstractions, config options, or error handling for cases the issue doesn't require, and don't assume unfinished parts of the codebase (e.g. stubbed services that throw NotImplementedException) are stable — check before building on top of them.
  • This project is under active development: expect bugs, missing pieces, and incomplete implementations elsewhere in the codebase. Do not "fix" things outside your issue's scope, even if you spot something wrong — file a new issue instead.
  • The test suite may or may not be reliable at any given time. If tests exist and run, use them to validate your change. If they don't cover your change, don't assume passing behavior — prioritize clean, correct, minimal code either way, and add a test if one is missing for the code you touched.
  • Keep the scope as small as possible while still fully addressing each issue.
  • Do not commit or push any implementation notes, plan files, or scratch markdown (e.g. IMPLEMENTATION.md, NOTES.md, TODO.md, *.plan.md). Keep these local only — they're covered by .gitignore, but double-check before committing.

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.
