What is agents-market-installer?

A repository workflow for finding, previewing, and installing specialized coding helpers, called subagents, for Claude Code, Codex, or OpenCode.

Use it to recommend a helper pack, inspect a registry, search for individual helpers, create a custom pack, preview changes, and install or check the result.

It reduces the work of choosing and setting up suitable coding helpers. It also shows the files, permissions, policy results, warnings, and source details before installation.

agents-market-installer — Skill for Claude Code by tt-a1i

Install

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.

Any agent

npx skills add tt-a1i/agents-market --skill agents-market-installer

Clone the repo

git clone --depth 1 https://github.com/tt-a1i/agents-market

Made for: Claude Code.

Or install agents-market-installer, the plugin that ships this one along with the rest of its 1 skill.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.00779
Opus 5.5	$0.00017	$0.00312
Sonnet 5.5	$0.00009	$0.00156
Haiku 4.5	$0.00004	$0.00078

Security

Grade A, and why

agents-market-installer 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 2mo 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agents Market Installer

Use the local agents-market CLI to recommend and install specialized coding subagent packs.

If the agents-market CLI is not installed, run the same commands through npx github:tt-a1i/agents-market#preview-0.1.0 (or npx @agents-market/cli once the npm package is published).

Workflow

Inspect the repository briefly so you understand the project type.
If the user provides a registry URL or bundle path, run agents-market registry info --registry <source> --json, summarize the source/version/checksum, then run agents-market registry lock --registry <source> after confirmation.
Run agents-market apply --target all --json to preview the recommended pack, audit, policy result, and file diff.
If the user names a pack, run agents-market apply <pack-id> --target all --json instead.
If the user wants a small custom set, run agents-market search <query> --json, create a pack with agents-market pack create <pack-id> --agent <ids...> --out ./registry/packs, then preview it with agents-market apply <pack-id> --target all --json.
Explain target files, permission implications, policy findings, warnings, and source/license status.
After user confirmation, run agents-market apply <pack-id> --target all --yes.
Verify install state with agents-market status --json, agents-market outdated --json, and agents-market doctor --strict --json.
Summarize installed files, pack version state, health warnings, and how the user can invoke the new agents.

Target Selection

Use --target claude for Claude Code only.
Use --target codex for Codex only.
Use --target opencode for OpenCode only.
Use --target all when the user wants cross-tool support or does not know which tool they will use.

Safety

Prefer apply because it combines recommendation, audit, policy, diff, and guarded install. Use lower-level commands such as recommend, audit, policy check, diff, and install only when the user needs custom control or troubleshooting.

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.
