Agent Skills Self-Load (Bootstrap)

Shared contract. Every agent_skills consumer agent self-loads its configured skills in its mandatory init step, so a project's .planning/config.json agent_skills.<agent-type> mapping reaches the agent that actually does the work — even when the orchestrator did not run bash init (e.g. a runtime whose Skill() delegation does not reliably execute the delegated workflow's bash, such as Cursor; see golem15/msd-core#1600 / #1601). This is the durable counterpart to the orchestrator-side injection documented under Agent Skills Injection.

When to run

In your mandatory init step — right after mandatory-initial-read.md / the Project skills discovery, before any other work.

Steps

1. Dedup guard (MANDATORY). Look at your own prompt. If it already contains an <agent_skills> block, the orchestrator already injected one — skip self-load entirely. Loading a second copy wastes context on runtimes where orchestrator-side injection also runs (e.g. Claude Code). The guard is what keeps the two seams from doubling the block.

2. Query your configured skills. Use your own agent type — the name: value in your frontmatter (e.g. an agent whose frontmatter says name: msd-executor queries msd-executor). The query is read-only and idempotent — it exits 0 with an empty block when nothing is configured for your type:

   _AGENT_SKILLS=$(msd_run query agent-skills <YOUR-FRONTMATTER-NAME> 2>/dev/null || true)
   

   The runtime msd_run resolver is the standard one from _runtime-launcher.snippet.sh; your own init already defines it.

3. Read every listed skill. The block emits entries as @<path>/SKILL.md includes — Read each one before starting work. If the block is empty, there is nothing to do (zero overhead).

What self-load does and does not cover

Skill form	Self-loads?	Notes
Project-relative path (skills/my-skill)	✅ everywhere	Read the @-include
Global personal (global:<name>)	✅ everywhere	resolves to the runtime global skills dir, then Read
Plugin-provided (global:<plugin>:<skill>)	Claude only	emitted as a Skill-tool directive on Claude; skipped with a warning on all other runtimes — the plugin/Skill-tool model has no equivalent elsewhere (#1601, #1258). Not closeable on Cursor.

Notes

• Idempotent and read-only. query agent-skills never mutates state; calling it twice (once by the orchestrator, once by the agent) is harmless because the dedup guard suppresses the second load.
• No new config keys. This reuses the existing agent_skills map and the existing buildAgentSkillsBlock / cmdAgentSkills machinery (src/init.cts). The 22 consumer agent types are mirrored in tests/agent-skills.test.cjs (CONSUMER_AGENTS) and guarded against drift by tests/agent-skills-bootstrap.test.cjs.
• Checkers / read-only agents. Bash is universal across consumer agents, so self-load works for plan-checkers, verifiers, and auditors too; the bootstrap assumes no tool an agent lacks.
