insyra AGENTS.md

insyra AGENTS.md is an instructions file for Codex, OpenCode from HazelnutParadise/insyra. It costs 5,377 tokens per session, scanned A, original, MIT.

Repository-specific instructions for AI coding agents working on Insyra, a Go library for data analysis with a command-line tool and related packages. They describe the repository, required project documents, and the expected workflow for changes.

In plain words
What is it for?
Use them when an AI agent is modifying the Insyra repository, especially for architecture changes, test design, precision decisions, migrations, or delivery work.
Why use it?
They give an agent the project context and tell it which decisions and status documents to read before making certain changes. This reduces the chance of ignoring local rules or established technical choices.

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

insyra 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 — 278 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

This file is the primary guidance for AI coding agents working in this repository. CLAUDE.md re-exports it via @AGENTS.md.

What This Repo Is

Insyra (github.com/HazelnutParadise/insyra) is a Go data analysis library (v0.3.x, "Huashan") providing:

  • DataList and DataTable as the core data structures
  • CCL (Column Calculation Language) — a domain-specific expression language for column transforms
  • A CLI/REPL (insyra binary) built with Cobra
  • Sub-packages for stats, plotting, LP, Python interop, parallel processing, file I/O, etc.

Required artifacts

Each entry says when reading it stops being optional. That trigger is the part that only exists here — the files describe their own contents.

  • ENG.md — the project's standing technical decisions: architecture, test seams, the precision contract, the measured thresholds, the assumptions everything rests on. Read it before changing architecture, choosing a test seam, deciding what precision something runs at, or writing a migration. Do not re-derive any of it from scratch; if a decision there is wrong, change it there.
  • delivery-status.md — where the project currently stands: phase, blockers, next output, next ticket. Read it first on arrival. It is deltas only, not a roadmap or a changelog.
  • openspec/changes/ — the tickets. Pick up anything whose blockers are all done; the milestone order in delivery-status.md carries the blocking edges, because OpenSpec has none between changes. Completed changes live in archive/.

Change Workflow — OpenSpec (required)

Every non-trivial change goes through the OpenSpec workflow. This repo is OpenSpec-initialized (see openspec/). Do NOT implement a feature, breaking change, new package, or substantial fix straight into the code — drive it through a change first:

  1. Propose — create the change (proposal + spec deltas + tasks) under openspec/changes/<change-id>/ (openspec-propose / openspec-new-change).
  2. Apply — implement the tasks (openspec-apply-change).
  3. Verify — confirm the implementation matches the artifacts (openspec-verify-change).
  4. Archive — once the change is implemented and merged, archive it into openspec/changes/archive/ (openspec-archive-change). Completed changes must be archived, not left sitting in openspec/changes/.

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.
