tripsage-ai: Instructions file for Codex

AGENTS.md

tripsage-ai AGENTS.md is an instructions file for Codex, OpenCode from BjornMelin/tripsage-ai. It costs 7,575 tokens per session, scanned C, original, MIT.

A project instruction file for coding agents working on TripSage AI, a travel application. It describes the application's technology, external services, coding behavior, planning, research, and output rules.

In plain words
What is it for?
Use it when developing TripSage's travel features, interface, data handling, payments, email, external travel APIs, or agent workflows.
Why use it?
It gives agents a shared description of the system and constraints, reducing incorrect changes and inconsistent decisions.

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

This is BjornMelin/tripsage-ai's own configuration. It tells Codex and OpenCode how to work on tripsage-ai 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 tripsage-ai 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 C, and why

tripsage-ai AGENTS.md scanned grade C 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 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **Safety:** No destructive commands (`rm -rf`, `git reset --hard`) unless requested. Never commit secrets. Delete obsolete files as part of replacements.

AGENTS.md – TripSage AI Contract

This file defines required rules for all AI coding agents in this repo. If anything conflicts, AGENTS.md wins.

0. Architecture and Stack

  • Frontend-first: All features at repository root. Next.js 16, React 19, TypeScript 6.
  • Data/State: Zod v4, Zustand v5, React Query v5, React Hook Form.
  • Backend: Supabase SSR, Upstash (Redis/Ratelimit/QStash), OpenTelemetry.
  • UI: Radix UI primitives, Tailwind CSS + CVA + clsx, Lucide icons.
  • External APIs: Amadeus (travel), Stripe (payments), Resend (email).

1. Agent Persona and Global Behavior

  • Tone: Precise, technical, concise. No buzzwords/emojis.
  • Correctness first: Never sacrifice for brevity. Include trade‑offs for complex tasks; mark unknowns as UNVERIFIED.
  • Autonomy: Use tools without asking. Maintain TODO list via update_plan.
  • Safety: No destructive commands (rm -rf, git reset --hard) unless requested. Never commit secrets. Delete obsolete files as part of replacements.
  • Evidence: Prefer primary docs (AGENTS.md, official docs, docs/) over blogs. Cite web research; mark inferences.
  • Output: Plain text with bullets/inline code by default; JSON only when requested/tool-required; reference file paths instead of code blocks.

2. Planning, Tools, and Research

2.1 Planning and investigation

  • For any non‑trivial or multi‑step change, use zen.planner plus update_plan (with exactly one in_progress step).
  • For design trade‑offs, use zen.consensus with weights: Solution Leverage 35%, Application Value 30%, Maintenance 25%, Adaptability 10%.

2.2 Search and documentation tools

  • Code and API questions: Use context7(resolve-library-id → get-library-docs),then exa.get_code_context_exa.
  • Research/web search: Use exa.web_search_exa.
  • Scraping/Crawling: Use exa.crawling_exa.

3. Project Layout and Responsibilities

  • Primary app (root): Next.js 16 workspace at repo root. Core AI in src/app/api/** route handlers. Shared schemas/types in src/domain/schemas (reuse server/client). Structure: src/app, src/components, src/lib, src/hooks, src/stores, src/domain, src/ai, src/prompts, src/styles, src/test, src/test-utils, src/__tests__.
  • Infrastructure: Scripts in scripts/; containers in docker/; tests in src/**/__tests__; docs in docs/; e2e tests in e2e/.

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.
