orcho-core: Skill for Claude Code

.agents/skills/orcho-core-verification-matrix/SKILL.md

orcho-core-verification-matrix is a skill for Claude Code, Codex from symphos-ai/orcho-core. It costs 83 tokens per session (598 once invoked), scanned A, original, Apache-2.0.

A testing guide for orcho-core, a software project with components such as an SDK, runtime sessions, command-line tools, and plugins. It maps changed areas to focused tests and checks.

In plain words
What is it for?
Use it to select tests for schema changes, prompts, sessions, parsers, command-line behavior, profiles, plugins, cross-project features, and related areas.
Why use it?
It helps developers choose relevant tests before running the project's full verification process.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is symphos-ai/orcho-core's own configuration. It tells Claude Code and Codex how to work on orcho-core 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 orcho-core configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/smartgamma/www/orcho/DEVELOPMENT_PIPELINE.md.

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

orcho-core-verification-matrix 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 11d 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.

Orcho Core Verification Matrix

Map changed orcho-core surfaces to focused test commands before the full integrity gate.

Owns

  • targeted test and smoke selection for orcho-core
  • pytest mark/path recommendations
  • downstream smoke recommendations before final gate

Does Not Own

  • implementation
  • domain semantics
  • final readiness gate -> orcho-integrity-pipeline

Test Map

full mock behavior relevant acceptance/integration mock flow

Invariants

  • Targeted tests do not replace final ruff, pytest gate, and git diff --check.
  • Public schema changes include snapshots and downstream smoke.
  • Prompt golden diffs must be reviewed, not blindly accepted.

Verification

  • This skill recommends commands; it does not replace running them.
  • If public schema or MCP-visible shape changes, include snapshot and MCP smoke commands.

Output

Name primary domain skill, targeted commands, whether full pytest is still required, downstream smoke, and blockers if any command cannot run.

Command Policy

  • Run commands from orcho-core unless the command explicitly names another repo.
  • Prefer python -m pytest -q <path> for targeted tests.
  • Final readiness still belongs to orcho-integrity-pipeline.

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.
