What is quinotospec-extension-manager?

An extension and preset manager for local, versioned agent configurations. It keeps a record of installed items and resolves which configuration should take priority.

It helps search, install, update, list, and inspect extensions and presets, and choose templates, commands, or skills from overrides, presets, extensions, and core files.

It avoids silently resolving conflicts, running remote code, or losing track of which local extension or preset is installed.

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	$0.00031	$0.00655
Opus 5.5	$0.00012	$0.00262
Sonnet 5.5	$0.00006	$0.00131
Haiku 4.5	$0.00003	$0.00065

Security

Grade A, and why

quinotospec-extension-manager 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.

The scan reads SKILL.md. This mod also ships 1 executable file (extension_manager.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Extension Manager

Gestiona el ciclo de vida de extensiones y presets sin ejecutar código remoto ni resolver conflictos silenciosamente.

Modelo

Extensiones: .quinoto-spec/extensions/<id>/extension.yml.
Presets: .quinoto-spec/presets/<id>/preset.yml.
Registro auditable: .quinoto-spec/extensions/.registry.
Catálogos locales: extensions/catalog.json y extensions/catalog.community.json.
Resolución de templates: quinotospec-template-resolver aplica overrides → presets → extensions → core.

Comandos

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . --json search jira

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . install --kind extension --source ./my-extension

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . update --kind extension --source ./my-extension

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . --json list

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . info --kind extension my-extension

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . remove --kind extension my-extension --yes

install y update validan el manifest antes de copiar, rechazan symlinks y escriben el registro atómicamente. remove exige --yes y solo elimina paths registrados.

Hooks

Los hooks se declaran en extension.yml bajo los 17 puntos del contrato. Listarlos es read-only:

python3 agent-dist/skills/quinotospec-extension-manager/extension_manager.py \
  --root . --json hooks --point before_apply

Ejecutar hooks automáticos requiere --run --yes; los hooks manuales solo se reportan. Los comandos se ejecutan sin shell, con timeout y código de salida visible.

Seguridad

No instalar fuentes HTTP por defecto; el catálogo debe entregar un path local verificable.
No modificar el core para registrar una extensión.
No ejecutar hooks auto durante install o update; hacerlo requiere una invocación explícita.
Rechazar IDs, paths, manifests y archivos fuente inseguros.
Registrar el cambio con quinotospec-update-changelog después de instalar, actualizar o remover.

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.
