kiro-discord-bot: Instructions file for Kiro

.kiro/steering/decision-failure-patterns.md

decision-failure-patterns is an instructions file for Kiro from nczz/kiro-discord-bot. It costs 9,181 tokens per session, scanned A, original, MIT.

A record of architecture decisions, known limitations, and recurring production failures for a repository. It explains when to document a rejected approach, an unsupported behavior, or a reusable debugging lesson.

In plain words
What is it for?
Use it during architecture changes, recurring bug fixes, deployments, runtime incidents, and regression prevention.
Why use it?
It keeps important decisions and failure patterns out of temporary chat history so future developers can avoid repeating them.

Instructions file for Kiro

Written for Kiro: installed under .kiro/. Also seen: mentions subagents; mentions AGENTS.md; mentions Codex.

This is nczz/kiro-discord-bot's own configuration. It tells Kiro how to work on kiro-discord-bot 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 kiro-discord-bot configures →

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

decision-failure-patterns 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 15d 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 — 758 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Decision And Failure Patterns

This file records how to avoid repeating known wrong turns. Use it when a task touches architecture direction, multi-bot behavior, cron/thread delivery, MCP tools, cwd/Kiro settings, stuck agents, release/deploy, or any recurring runtime failure.

When To Update This File

Update this file when any of these happen:

  • A proposed fix is rejected because it solves the symptom in the wrong layer.
  • A behavior is intentionally left unsupported or out of scope.
  • A production/runtime issue reveals a reusable debugging pattern.
  • A bug fix adds a regression test for a failure that could return.
  • A release/deploy incident exposes a missing verification signal.
  • A future issue should be opened, but the current change should not start that architecture work.
  • A new architecture layer, shared helper, runtime mode, deployment target, or MCP tool category changes the source of truth documented in steering.
  • The root AGENTS.md entrypoint stops matching the active project architecture, security boundaries, verification expectations, or cross-agent source-of-truth map.

Do not hide these decisions only in chat history. Future maintainers need the decision, tradeoff, and trigger conditions in the repository.

Decision Record Template

Use this shape for significant direction changes:

Decision:
- What we decided.

Context:
- Current behavior and evidence.
- User goal or operational problem.

Rejected alternatives:
- Option and why it was rejected.

Current scope:
- What this change will do now.
- What this change explicitly will not do.

Future trigger:
- What evidence or requirement should reopen the decision.

Verification:
- Tests, logs, docs, or runtime checks that prove the current scope.

Current Architecture Non-Goals

These are deliberate boundaries unless a new architecture task changes them:

  • This project is not currently a single-process orchestrator for multiple Discord bot identities.
  • Multiple deployed bots in one Discord server are independent runtimes. They may share code and configuration patterns, but they do not have a reliable distributed coordination layer through Discord mentions.
  • Do not rely on bot-to-bot tag conversations as a durable task handoff mechanism. Discord delivery order, network delay, thread membership, permissions, and bot filtering can make that unreliable.
  • Do not teach agents to coordinate by recursively asking each other questions in Discord. That creates latency, loop, mention-target, and accountability problems.
  • Do not patch multi-bot coordination by weakening requiresHumanMention, peer filtering, MCP policy, or safe egress.
  • If reliable multi-bot orchestration becomes a product goal, design it as an explicit server-side architecture with owned routing, state, audit, and bot identity boundaries.

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.
