Agent Context Bootstrap

Goal

Create or improve repo-local agent context so future agents can work from the repository's real commands, docs, issue tracker rules, domain language, ADRs, validation commands, and skill routing without overwriting existing instructions.

When to use

• A repository lacks AGENTS.md or agent-facing docs.
• The user wants Codex, Claude Code, Cursor, or another agent to follow local workflow rules.
• A repo needs issue tracker notes, triage labels, domain docs, ADR locations, or validation commands documented.
• A downstream repo needs predictable first-run agent setup before using workflow skills.

When not to use

• The user only wants a one-time handoff; use handoff.
• The user wants a repo health report without changing context files; use repo-health-audit.
• The repository already has clear agent instructions and the user did not ask for edits.
• The user wants to publish a skill catalog; use skill-repo-curator.

Inputs to inspect

• Existing AGENTS.md, CLAUDE.md, .codex/, .cursor/, CONTEXT.md, CONTEXT-MAP.md, and docs files.
• README.md, package files, validation scripts, CI workflows, issue templates, labels, and .github/.
• docs/adr/, architecture docs, domain docs, and existing docs/agents/.
• Maintainer-provided issue tracker, triage labels, validation commands, runtime conventions, and domain-specific workflow notes.
• git status --short before editing.

Workflow

1. Inspect current agent instructions and docs before proposing edits.
2. Infer what is safe from repo files: package manager, validation scripts, ADR location, CI commands, issue templates, and existing domain docs.
3. Ask for maintainer input only when the repo cannot answer a hard setup decision: issue tracker, live label names, domain glossary location, validation command, or agent runtime convention.
4. Create or update docs/agents/issue-tracker.md, docs/agents/triage-labels.md, docs/agents/domain-docs.md, docs/agents/validation.md, and docs/agents/skill-routing.md.
5. Add or update an ## Agent skills block in the primary agent instruction file, usually AGENTS.md.
6. Preserve existing user instructions and never overwrite unrelated sections.
7. Validate links, formatting, and available repo checks.

Setup docs

Use these conventions when writing downstream setup docs:

• Hard dependencies, such as issue tracker mutation rules, must point to docs/agents/issue-tracker.md and docs/agents/triage-labels.md.
• Validation commands belong in docs/agents/validation.md.
• Skill routing and local skill preferences belong in docs/agents/skill-routing.md.
• Soft dependencies, such as domain language and ADRs, should point to docs/agents/domain-docs.md without blocking normal work when the docs are missing.

Ask vs infer

• Infer package manager, validation scripts, ADR location, issue templates, CI commands, and existing docs from files.
• Ask for the canonical issue tracker when none is obvious.
• Ask before inventing labels, project board states, assignment rules, or live mutation policy.
• Ask for domain glossary ownership if multiple docs could be the source of truth.
• Ask before replacing existing agent instructions; otherwise append or update bounded sections only.

Safety rules

• Do not overwrite existing instructions blindly.
• Do not include credentials, internal hostnames, private repo paths, or customer details.
• Do not assert commands work unless verified.
• Do not create tool-specific files such as CLAUDE.md or .cursor/rules unless the repo already uses them or the user asks for that runtime.
• Do not mutate live issue trackers, labels, projects, or repository settings.

Assets

Use only when creating new files:

• assets/agents-block.md for an AGENTS.md skill block.
• assets/issue-tracker.md for tracker notes.
• assets/triage-labels.md for label conventions.
• assets/domain-docs.md for domain documentation mapping.
• assets/domain-language.md for glossary structure.
• assets/validation.md for validation commands.
• assets/skill-routing.md for skill selection guidance.

References

Read only when needed:

• assets/agents-block.md
• assets/domain-docs.md
• assets/domain-language.md
• assets/issue-tracker.md
• assets/skill-routing.md
• assets/triage-labels.md
• assets/validation.md

Scripts

No bundled scripts.

Output format

Return:

1. Files inspected
2. Context added or proposed
3. Existing instructions preserved
4. Validation result
5. Follow-up decisions needed

Failure modes

• If the issue tracker is unknown, stop before writing tracker-specific instructions.
• If existing instructions conflict, surface the conflict instead of overwriting.
• If validation cannot run, explain what tool or command is missing.
• If the repo has no domain glossary, create a placeholder or document the selected source of truth without inventing domain vocabulary.

Completion criteria

• Future agents can find repo rules, validation commands, issue tracker guidance, and domain docs.
• Existing instructions remain intact unless intentionally changed.
• Sensitive details are excluded.
• Hard workflow dependencies point to docs/agents/ setup docs.
