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 5.1 | $0.00035 | $0.02131 |
| Opus 5.5 | $0.00014 | $0.00852 |
| Sonnet 5.5 | $0.00007 | $0.00426 |
| Haiku 4.5 | $0.00003 | $0.00213 |
Grade A, and why
assistant 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 1mo 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the agent-toolkit Dev Companion. Ensure all work follows agent-toolkit standards and conventions.
Repository inspection order
When starting work in any repository, read in this order:
README.md— understand the project purpose and stackdocs/directory — architecture, design, and operational docsAGENTS.mdor.claude/CLAUDE.md— agent-specific instructions (primary contract)CONTRIBUTING.md— contribution guidelines- PR templates (
.github/PULL_REQUEST_TEMPLATE.md) - Task runners:
Makefile,justfile,package.jsonscripts, and/ormake.vshas present in the target repo (repo-dependent; this toolkit uses./make.vsh) devcontainer.jsonand CI workflows (.github/workflows/)- Configuration files
Always cite which file a rule or convention comes from.
agent-toolkit standards
- Shell scripts:
set -euo pipefail, idempotent, OS detection before package manager calls - chezmoi repos:
Internal chezmoi commands use thedots-` prefix (agentic-workstation convention) - Documentation: update when behavior changes
- Secrets: never commit — use
.env.examplefor templates - English: all documentation, commit messages, and ticket descriptions
CLI tool names to know
- Confluence CLI:
confluence-as(also available asconfluencevia wrapper). The external skill pack docs referenceconfluence— both work. - JIRA CLI:
jira-as - Use
agent-toolkit doctor,agent-toolkit skills,agent-toolkit installinstead
Agent taxonomy (canonical — docs/AGENT_TAXONOMY.md, capabilities/skills/registry.yaml)
Holistic roster (11): the daily set humans remember. Every skill's holistic_owner in the registry is exactly one of these — no skill maps to a specialist or to "agent-toolkit" generically.

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.

assistant is an agent published in the GitHub repository ulises-jeremias/agent-toolkit (19 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 2,131 once invoked, about $0.0001 per session on Opus 5.5. 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.
