Author and refine reference skills, task-style command skills, and path-scoped rules using one repository-grounded workflow. TRIGGER when: asked to create, build, scaffold, convert, review, or update a skill, command, workflow, rule, coding standard, or contextual instruction. Skills are the canonical primitive for a reusable role, procedure, or body of judgment — there is no project-agent artifact type.
Source documentation, not instructions for this website. Review permissions before running any commands.
Build one artifact through the matching type reference. Run inline and inherit the session model; do not fork or override the model unless the artifact being authored has an independently justified need.
Arguments received: $ARGUMENTS
Treat the first whitespace-delimited argument as TYPE and the remainder as
the artifact name, request, or path.
Accept exactly these types:
| Type | Read and follow |
|---|---|
skill | references/skill.md |
command | references/command.md |
rule | references/rule.md |
If TYPE is missing or unknown, or the remaining request is empty or only
whitespace, print the following and stop without reading type references or
modifying files:
Usage: /builder <skill|command|rule> <name-or-request>
agent is not an artifact type. A reusable role, procedure, or specialist
judgment is authored as a skill; a bounded isolated worker context is an
execution choice made by /delegate, not a repository artifact.
Read the selected reference completely, then execute its protocol against the
remainder of $ARGUMENTS. The selected reference is authoritative for artifact
shape and type-specific validation.
Apply these steps for every valid type before the selected reference's type-specific steps.

Run inline and inherit the session model; do not fork or override the model unless the artifact being authored has an independently justified need. Arguments received: `$ARGUMENTS` ## Dispatch 1. Treat the first whitespace-delimited argument as `TYPE` and the remainder as the artifact name, request, or path. 2. Accept exactly these types: | Type | Read and follow | |------|-----------------| | `skill` | `references/skill.md` | | `command` | `references/command.md` | | `rule` | `references/rule.md` | 3. If `TYPE` is missing or unknown, or the remaining request is empty or only whitespace, print the following and stop without reading type references or modifying files: ```text Usage: /builder <skill|command|rule> <name-or-request> ``` `agent` is not an artifact type. A reusable role, procedure, or specialist judgment is authored as a skill; a bounded isolated worker context is an execution choice made by `/delegate`, not a repository artifact. 4. Read the selected reference completely, then execute its protocol against the remainder of `$ARGUMENTS`. The selected reference is authoritative for artifact shape and type-specific validation. ## Shared protocol Apply these steps for every valid type before the selected reference's type-specific steps. ### 1. Discover local authority - Find and read applicable `AGENTS.md` and `CLAUDE.md` files from repository root through the target directory. More local instructions win; in one directory, `AGENTS.md` is canonical. - Identify the source-of-truth artifact directory. In Open Harness and equipped projects, edit `.agro/skills/`; provider directories such as `.claude/`, `.codex/`, and `.pi/` are generated or symlinked exposure surfaces. - Outside an Open Harness layout, follow the target project's documented canonical path rather than creating `.agro/` speculatively. - Inspect two or three nearby artifacts of the same type. Reuse their naming, frontmatter, structure, tone, and validation conventions. - Search for an existing artifact with the same purpose. Prefer a focused update or explicit consolidation over a near-duplicate. - Consult compiled harness patterns before proposing a change. Run `/wiki query <artifact-name-or-subsystem> --patterns` and read what it returns: each page records a failure mode, its root cause, and a workaround this harness already paid for. Cite the motivating `[[pattern-...]]` slugs in the report. - Read `.agro/evals/decisions/skill-impact.md` for prior proposals against the same target. Do not re-propose a change recorded there as `REJECTED` unless new evidence contradicts the recorded validation; when you do, cite the prior record id. ### 2. Define the contract Before editing, state internally: - the artifact's one-sentence purpose and concrete triggers; - who invokes or consumes it; - what is in scope, out of scope, and considered done; - the minimum tools, context, side effects, and supporting resources required; - which behavior is repository-specific and must be grounded in inspected files. Ask a question only when unresolved ambiguity would materially change the artifact or create unsafe side effects. Otherwise use the request and repository evidence. ### 3. Author narrowly - Use lowercase kebab-case names and one artifact per coherent concern. - Put matching and trigger information in frontmatter, not only in the body. - Use imperative, operational language. Remove generic expertise prose that does not change behavior. - Prefer the least privilege and smallest context footprint that completes the job. - Cite real local paths and commands only after verifying them. - Do not modify unrelated files, generated provider mirrors, or user work in the working tree. ### 4. Validate and report - Validate frontmatter delimiters and required fields without assuming optional YAML libraries are installed. - Check every referenced path, invocation, tool, and supporting file. - Enforce the selected reference's size, safety, and semantic checks. - When `.agro/scripts/link-providers.sh` exists and canonical `.agro/` primitives were changed, run `bash .agro/scripts/link-providers.sh --check`. - Run `git diff --check` when inside a Git worktree. - Report the files created, updated, or removed; the resulting invocation or loading behavior; key design choices; and validation evidence. Never claim a check ran if it did not. - Append a `PROPOSED` record to `.agro/evals/decisions/skill-impact.md` when a skill edit lands: the next `SI-nnnn` id, the one-sentence proposal, the single target artifact, the motivating pattern slugs, and the unified diff scoped to that target path. `motivating patterns: none (direct request)` is a legitimate value — record it rather than inventing a pattern to cite. Stage the ledger (`.agro/evals/decisions/` is tracked, so a plain `git add`) and report the allocated id. Never edit an existing record.
