contextos-agents: Skill for Claude Code

.agents/core/skills/gstack-roles/SKILL.md

gstack-roles is a skill for Claude Code, Codex from kok-o/contextos-agents. It costs 17 tokens per session (219 once invoked), scanned A, original, Apache-2.0.

A compatibility alias for engineering-workflow, a set of instructions for planning, implementing, checking, and reporting software changes.

In plain words
What is it for?
Use it only when an existing configuration or user explicitly names gstack-roles; new setups should use engineering-workflow instead.
Why use it?
It prevents older configurations that refer to this name from loading duplicate or different guidance.

Skill for Claude CodeCodex

Which agent this was written for is unclear — built for gstack. Also seen: installed under .agents/ (shared by several agents); built for gstack.

This is kok-o/contextos-agents's own configuration. It tells Claude Code and Codex how to work on contextos-agents itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything contextos-agents configures →

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

gstack-roles 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 today.

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

gstack-roles

Overview

Deprecated compatibility identifier. Use engineering-workflow for the canonical instructions.

When to Use

An existing configuration or user explicitly names gstack-roles.

Rules & Patterns

Apply the canonical skill without loading a duplicate process. Existing authorization, proportional verification, and optional role declarations carry forward. The resolver redirects this identifier and reports an alias warning.

Code Examples

Explicit gstack-roles selection resolves to engineering-workflow; inspect the resolver result rather than assuming both bodies were loaded.

Validation Checklist

  • Canonical guidance is used.
  • Alias resolution adds no duplicate body.
  • Evidence scope and limitations are stated.

Common Mistakes

Treating this compatibility name as an independent engine or a mandatory ceremony.

Integration Notes

Keep legacy links available. Read references/roles.md only for compatibility details.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
