Written for Codex and OpenCode: the file is AGENTS.md. Also seen: reads .claude/ paths; mentions AGENTS.md.

This is pantheon-org/tekhne's own configuration. It tells Codex and OpenCode how to work on tekhne 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 tekhne 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 B, and why

tekhne AGENTS.md scanned grade B 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 today.

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.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

`--budget-chars` fixes the budget outright; `--chars-per-token` (default 4) changes the derivation. Precedence is `--budget-chars`, then `--context-tokens`, then `--fraction` alone (a band), then the 8000 fallback. `--fr

Tekhne Agent Collaboration Guide

This file defines how LLM agents should work in this repository.

Project Purpose

  • Maintain a curated collection of reusable agent skills under skills/.
  • Keep skill content modular, discoverable, and easy to lint/validate.
  • Prefer small, targeted edits over broad rewrites.

Repository Map

  • skills/<domain>/<skill-name>/SKILL.md: Primary entry point for a skill.
  • skills/<domain>/<tool>/{generator,validator}/SKILL.md: Generator/validator pairs (consolidated under <tool>/tile.json).
  • skills/<domain>/<skill-name>/AGENTS.md: Optional deep navigation for that skill.
  • skills/<domain>/<skill-name>/references/: Focused reference documents.
  • skills/<domain>/<skill-name>/scripts/: Utility scripts used by a skill.
  • skills/<domain>/<skill-name>/templates/: Reusable templates (mostly YAML).
  • skills/<domain>/<skill-name>/schemas/: JSON schemas for validation.
  • .context/: Working notes and generated analysis artifacts.
  • Tools live in their own repositories (pantheon-skill-auditor, pantheon-journal, pantheon-adr, sharing agentic-harness-dev-kit); this repository pins the released auditor in mise.toml.
  • probes/: Invocation probes, one JSON file per skill (see Invocation probes below); probes/baselines/ holds committed score reports.
  • scripts/catalog/: TypeScript catalog generator for README.md and the docs tiles page.

Note: Generator/validator pairs are consolidated at the tool level (e.g. terraform-generator and terraform-validator share skills/infrastructure/terraform/tile.json).

Domain Organization

13 domains: ci-cd/, infrastructure/, repository-mgmt/, development/, agentic-harness/, testing/, software-engineering/, observability/, documentation/, package-mgmt/, project-mgmt/, specialized/, comedy/.

See skill-taxonomy.md in the auditor repository for classification criteria.

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.
