tinysdlc: Instructions file for Codex

AGENTS.md

tinysdlc AGENTS.md is an instructions file for Codex, OpenCode from Minh-Tam-Solution/tinysdlc. It costs 1,390 tokens per session, scanned A, original, MIT.

Project instructions for TinySDLC agents working in a team of assistants. They describe setup logging, persistent operation, heartbeat monitoring, and message-based coordination with teammates.

In plain words
What is it for?
Use them to record initial setup, stay responsive during ongoing work, and delegate tasks through tagged messages to named agents.
Why use it?
They make agent work visible across sessions and define how requests are sent to one or several teammates. This reduces confusion about who is responsible for each task.

Instructions file for CodexOpenCode

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

This is Minh-Tam-Solution/tinysdlc's own configuration. It tells Codex and OpenCode how to work on tinysdlc 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 tinysdlc configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/jliao/.tinysdlc/files/report.pdf].

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

tinysdlc 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 6d 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 — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

TinySDLC - Multi-team Personal Assistants

Running in persistent mode with:

  • Teams of agents
  • Telegram, WhatsApp, Discord message integration
  • Heartbeat monitoring (with heartbeat.md file)

Stay proactive and responsive to messages.

Setup Activity

On first run, log your setup here so it persists across conversations:

  • Agent: [your agent id]
  • User: [user's name]
  • Dependencies: [e.g. agent-browser installed: yes/no]
  • Anything else that's super important

Keep this section updated and simple or complete first-time setup tasks.

Team Communication

You may be part of a team with other agents. To message a teammate, use the tag format [@agent_id: message] in your response.

If you decide to send a message, message cannot be empty, [@agent_id] is not allowed.

Single teammate

  • [@coder: Can you fix the login bug?] — routes your message to the coder agent

Multiple teammates (parallel fan-out)

You can message multiple teammates in a single response. They will all be invoked in parallel.

Separate tags — each teammate gets a different message:

  • [@coder: Fix the auth bug in login.ts] [@reviewer: Review the PR for security issues]

Comma-separated — all teammates get the same message:

  • [@coder,reviewer,tester: Please share your status update for the standup.]

Shared context

When messaging multiple teammates, any text outside the [@agent: ...] tags is treated as shared context and delivered to every mentioned agent. Use this for agendas, background info, or instructions that apply to everyone — then put agent-specific directives inside each tag.

We're doing a standup. The sprint ends Friday and we have 3 open bugs.
Please reply with: (1) status (2) blockers (3) next step.

[@coder: Also list any PRs you have open.]
[@reviewer: Also flag any PRs waiting on you.]
[@tester: Also report test coverage for the auth module.]

Each teammate receives the full shared context plus their own directed message. Keep shared context concise — it's prepended to every teammate's message.

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.
