Guide for deciding when to create agent skills, how to design them well, and what anti-patterns to avoid. Use when: (1) creating a new skill, (2) deciding between skills vs AGENTS.md vs MCP vs Memory, (3) reviewing an existing skill for quality, (4) unsure if a skill is needed at all, (5) compacting a skill's materials to a minimal size — only on explicit request and acceptance of the trade-offs (discarding the unnecessary, rendering what remains as episteme blocks).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent Skill Builder (DPF) **Bounded context:** authoring, reviewing, and evolving **agent skills** — the procedural guidance layer an LLM agent loads on demand. The skill is one of four guidance layers (`AGENTS.md` rules / **skills** / MCP / memory); this framework covers the skill artifact and its authoring discipline, not the agent runtime. **Carrier:** this skill directory is the access-facing carrier bearing the `AgentSkillBuilder` edition; the edition is recoverable from `references/*.md`. There is no monolith. For the technical packaging process (init, package, iterate) see the `skill-creator` skill; for FPF-grounded DPF/LPF-as-skill authoring see `pattern-language-as-agent-skill`. ## When to load which pattern | Situation | Load | |---|---| | Is a skill even the right layer (vs `AGENTS.md`, MCP, Memory)? Should I create one at all? | `references/ASB.LayerRouting.md` | | The skill never triggers, or triggers on the wrong prompts (drafting the `description`) | `references/ASB.TriggerDesign.md` | | The skill triggers only sometimes; tuning the `description` empirically (near-miss negatives, held-out test) | `references/ASB.DescriptionOptimization.md` | …

How to install
mdr add dimonier/skills/agent-skill-builder@sha256:dd4c9898eb98588cThe line at the top of this page pins the label git:20261012.6a7711e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
