skilltap: Instructions file for Codex

AGENTS.md

skilltap AGENTS.md is an instructions file for Codex, OpenCode from nklisch/skilltap. It costs 1,307 tokens per session, scanned A, original, MIT.

Project instructions for skilltap, a tool that manages agent environments, plugins, skills, marketplaces, and shared instructions.

In plain words
What is it for?
Use them when designing or changing skilltap, especially its command handling, configuration updates, and support for different agent systems.
Why use it?
They give contributors the product rules, architecture, and expected command behavior in one place.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is nklisch/skilltap's own configuration. It tells Codex and OpenCode how to work on skilltap 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 skilltap 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

skilltap AGENTS.md 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.

skilltap

Product

skilltap is a personal control plane for managing supported agent harness environments. It adopts, reconciles, and updates native marketplaces, plugins, complete skill directories, MCP configuration, and shared instructions.

It does not provide discovery, recommendations, security scanning, a TUI, or compatibility with the previous implementation.

Foundation

Read these before designing or implementing changes:

  • docs/VISION.md — purpose, audience, principles, and exclusions.
  • docs/SPEC.md — authoritative behavior, commands, state, and reconciliation.
  • docs/ARCH.md — Rust architecture and module boundaries.
  • docs/UX.md — non-interactive CLI behavior and output.
  • docs/HARNESS-CONTRACTS.md — Codex and Claude native contracts.

Foundation documents describe current or intended truth. Planned and time-bound work belongs in .work/.

Product Constraints

  • Commands are deterministic and non-interactive.
  • Bare scoped commands operate globally.
  • --project targets the current project.
  • --project <path> targets another project.
  • --all-scopes targets the managed computer.
  • --target selects one registered harness or all enabled harnesses.
  • ~/AGENTS.md is the canonical global instruction file.
  • A skill is the complete directory containing top-level SKILL.md.
  • Native harness lifecycle commands take precedence over file materialization.
  • Cross-harness transfer must be faithful or reported as partial.
  • Partial foreground operations require explicit acknowledgment.
  • Daemon updates never acknowledge partial operations or overwrite drift.
  • skilltap does not search or browse marketplace contents.

Architecture

The implementation is a stable Rust workspace:

  • skilltap-core owns domain types, state, planning, reconciliation, compatibility, and updates.
  • skilltap-harnesses owns the typed target registry, distinct native harness adapters, and user-service adapters.
  • skilltap-cli owns argument parsing, rendering, and exit codes.
  • skilltap-test-support owns fixtures and isolated test environments.

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.
