In plain words
What is it for?
Use it when making structural changes, updating the changelog, working on the Rust core or user interface, or following Kendex's review and planning rules.
Why use it?
It explains where different kinds of code belong, how generated TypeScript bindings are handled, and how changes should be documented and reviewed.

Instructions file for CodexOpenCode

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

This is vanillagreencom/kendex's own configuration. It tells Codex and OpenCode how to work on kendex 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 kendex 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

kendex 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 10d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 53 lines — stays where its author put it; the contents beside it link to each section on GitHub.

kendex

Desktop app and thin CLI (Rust + Tauri + React) for managing AI coding-harness customizations: agents, skills, hooks, commands, MCP servers, plugins and Pi extensions across a global scope and per-project scopes. This repository is also the default catalog every kendex install subscribes to (agents/, skills/, hooks/, commands/, pi-extensions/).

Commands

  • tools/setup: arms the commit chain in a fresh clone, beside the commit-guards commit-msg gate. A stray commit-msg hook in the git hooks directory calling a repo-local lane this repository lacks blocks every commit; delete it and run tools/setup again.
  • tools/guard: the last lane of the pre-commit chain, named by COMMIT_GUARDS_PRE_COMMIT_LOCAL; read the script, it is the list of repo-specific rules.
  • npm ci --prefix ui: installs the UI, in the main checkout only.
  • KENDEX_SOURCE_COMMIT=$(git rev-parse HEAD) cargo build --release -p kendex-cli: the self-install; copy the binary to ~/.cargo/bin/kendex before running kendex apply or kendex verify on this tree.
  • cargo test -p kendex-app -- --ignored regenerate_bindings: regenerates ui/src/bindings.ts after a command-surface change.

Conventions

  • Before writing or changing code, load the code-quality skill.
  • Open work lives in Linear (team KEN); scratch goes to tmp/ (gitignored), never /tmp. A plan, a research report or a measurement is an attachment on its Linear issue or a file under tmp/, never a tracked file under docs/.
  • A lane or research run that records another repository's data writes it to that repository's own tracker, never into the kendex tree.
  • A change under crates/ or ui/ ships a changelog fragment, one consumer-facing list item in changelog.d/<section>/<name>.md per changelog.d/README.md, or says [no-changelog] in the subject; the commit-guards commit-msg gate holds it, and changelog-entries --collate folds the fragments in at release. Compatible catalog content writes no kendex fragment and causes no kendex release. Released execution code and engine compatibility requirements follow changelog.d/README.md.
  • A source with a tracked render (skills/, agents/<n>.md, hooks/<n>) lands the render in the same commit; the rule is in skills/AGENTS.md.
  • kendex-local.toml is this repository's own manifest. A rule for kendex alone, not for every install of a catalog skill, goes in its [skill-instructions], which the render writes into .agents/skills/<name>/SKILL.md; skills/ ships to every install.
  • Review bots follow .github/instructions/code-review.md, which Code Review Rules below points them at, and .github/instructions/*.instructions.md; engineering rules are the code-quality skill, round scope the dev skill, finding dispositions skills/reviewer/references/finding-disposition.md.
  • A doc under docs/architecture/ is one principle; update it when a change makes a claim in it false, never beside a code change that falsifies nothing. A decision record exists only under the decider skill's bar.
  • docs/legal/ (privacy.md, terms.md) is product content shipped to users: the Terms of Service and Privacy Policy the first-run accept step records. It takes no "Read when" line.

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.
