task-agent AGENTS.md

A project instruction file that tells coding agents how to work in this repository, including task rules, documentation duties, and delivery conventions.

In plain words
What is it for?
Use it to guide substantial changes to task handling, agent workflows, skills, resuming work, publishing, and related documentation.
Why use it?
It keeps agent behavior and project documentation consistent, while discouraging unnecessary code and duplicated instructions.

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

task-agent 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 yesterday.

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.

Task Agent Project Rules

This repository contains a generic assistant workspace built around autonomous agent workflows.

Core Rule

Any substantial change to the agent engine must update documentation for both agents and humans in the same change.

Before implementation or architecture review, use this order: do nothing; remove or disable unnecessary behavior; configure or reuse the existing path; simplify the existing implementation; only then write the smallest necessary code. New code carries the burden of proof. A reviewer treats avoidable code or a more complex mechanism as a defect even when tests pass.

A substantial change includes:

  • task lifecycle or task artifact structure
  • skill discovery or skill execution rules
  • agent orchestration behavior
  • restore, resume, or publication conventions

If a change modifies one of these areas, update the relevant project docs before finishing the task.

Documentation Boundaries

  • AGENTS.md defines project-wide operating rules.
  • docs/ explains repository architecture and workflows.
  • Each skill documents its own behavior in its own SKILL.md.

Do not duplicate skill-specific instructions in project-level docs.

Agent entry points must not duplicate rules either. AGENTS.md is canonical for project rules, .cursor/rules/*.mdc for always-on rules, and skills/ for skills. CLAUDE.md only imports them and .claude/ only holds symlinks into them. Edit the canonical file, never a .claude/ path, and add a CLAUDE.md import line when a new Cursor rule is added. See docs/claude-code-setup.md.

Task Conventions

Every substantial user task gets its own directory under tasks/ before substantive work begins. The default is to create a task; skipping is only appropriate when the request is clearly trivial or the user explicitly opts out of task artifacts.

A request is substantial when any of these apply:

  • it has more than one meaningful step, such as research, implementation, verification, or documentation
  • it creates or changes scripts, configuration, services, documentation, or durable artifacts
  • it needs live checks against external systems, APIs, browsers, SSH, or other runtime services
  • it performs work in another repository or absolute path outside this workspace
  • it is a follow-up that continues the same non-trivial goal

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.
