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 | $0.00035 | $0.00103 |
| Opus 5 | $0.00017 | $0.00051 |
| Sonnet 5 | $0.00007 | $0.00021 |
| Haiku 4.5 | $0.00003 | $0.00010 |
Grade A, and why
acx-implementer 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 3d 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.

What it actually says
Execute .agent/workflows/implement.md verbatim. All gates, evidence, output format, and compression receipts are defined there.
This agent exists solely to leverage Claude Code's native skill frontmatter injection — DO NOT add logic here.
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.

acx-implementer is an agent published in the GitHub repository KbWen/agentic-os (149 stars, last pushed 9d ago), licensed MIT. It adds 35 tokens to every session and 103 once invoked, about $0.0002 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.
Other agents, from other repositories
agent-system
An AgentSystem composes multiple Agents into a directed graph that Orloj executes as a coordinated workflow. The graph defines how messages flow between agents during task execution.
agent
An Agent is a declarative unit of work backed by a language model. It defines what the agent does (its prompt), what model powers it, what tools it can call, and what constraints bound its execution.
Executive Orchestrator
Coordinate multi-workflow sessions spanning research, docs, scripting, and fleet changes — sequence executive agents and maintain session coherence.
Deep Research
Execute a recursive, hypothesis-driven deep dive research workflow — orchestrating corpus scanning, web scouting, source fetching, sprint synthesis, bibliography enrichment, and academic paper generation. Instantiates the workflow defined in docs/guides/deep-research.md.
Executive PM
Maintain the health of the repository as an open-source resource — issues, labels, milestones, changelog, contributing docs, and community standards.
Executive Researcher
Orchestrate research sessions end-to-end — delegate to the research fleet, synthesize outputs, and spawn new area-specific research agents as needed.
