Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01723 | $0.01723 |
| Opus 5 | $0.00861 | $0.00861 |
| Sonnet 5 | $0.00345 | $0.00345 |
| Haiku 4.5 | $0.00172 | $0.00172 |
Grade A, and why
ase 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 2d 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
About
Agentic Software Engineering (ASE) is the opinionated companion tooling of Dr. Ralf S. Engelschall for combining Agentic AI Coding with Software Engineering in tools like Anthropic Claude Code CLI. ASE consists of an agent tool plugin (hooks, skills, sub-agents, meta files), a Command-Line Interface (CLI) tool, and a per-project background service bridged into the agent tool as a Model-Context-Protocol (MCP) server.
The primary target agent tool is Anthropic Claude Code CLI; GitHub
Copilot CLI and OpenAI Codex CLI are secondary targets, selected via
ASE_TOOL=copilot resp. ASE_TOOL=codex or the --tool CLI option.
Repository Layout
ASE (Agentic Software Engineering) ships three deliverables from one repo:
plugin/: the agent tool pluginplugin/skills/ase-xxx-xxx/: the 50 skills, each with aSKILL.md(agent instructions) and ahelp.md(Unix-style manual page)plugin/agents/: the sub-agent definitions leveraged by the skillsplugin/meta/: the shared meta files (constitution, tenets, persona, dialog, getopt, and artifact format conventions), exposed to skills viaase meta <name>; the specification formatase-format-spec.mdincludes the SpecBook models and formats descriptionase-format-specbook.mdand the standard SpecBook schema configurationase-format-specbook.yaml, both generated at build-time by SpecBook (@rse/specbook)plugin/hooks/: the per-agent-tool hook wiring (hooks.json,hooks-copilot.json,hooks-codex.json)plugin/.claude-plugin/,plugin/.codex-plugin/,plugin/.github/plugin/: the per-agent-tool plugin manifests
tool/: the@rse/aseCLItool/src/ase.ts: the entry point, wiring all top-level commandstool/src/ase-*.ts: one module per top-level command (setup,config,mcp,service,hook,statusline,task,artifact,spec,meta,compat,diagram,worktree,mint) plus support modules (log,stdio,getopt,kv,markdown,skills,sleep,timestamp,version)tool/bin/ase: the published shim, loading compiled output fromdst/tool/plugin/andtool/.claude-plugin/: build-time copies ofplugin/and.claude-plugin/-- never edit them, they are regenerated
pages/: the GitHub Pages site (https://ase.tools), an Astro projectpages/src/data/*.ts: the content data, especiallyskills.ts(the single source of truth for skill grouping and ordering),highlights.ts,methods.ts,comparison.ts,fit.ts,testimonials.ts, andsite.tspages/src/components/*.astro: the page sections and UI components, assembled inpages/src/pages/index.astro
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.

ase AGENTS.md is an instructions file published in the GitHub repository rse/ase (47 stars, last pushed 4d ago), licensed Apache-2.0. It adds 1,723 tokens to every session, about $0.0086 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
