Closes the gap between ClaudeForge and the Anthropic docs at
code.claude.com/docs/en/memory (and its linked hooks / skills / plugins
pages). Five tightly-scoped changes, each verified by smoke test.
A. Fix guardian hook frontmatter shape (agent/claude-md-guardian.md)
The previous array-of-{event, commands} shape did not match the
documented schema (hooks: { EventName: [{ matcher, hooks: [{ type,
command }] }] }), so the guardian's hooks silently did not fire.
Rewritten to the canonical keyed-object shape with PostToolUse,
PreToolUse, SessionStart, and the new InstructionsLoaded event.
B+C. Plugin-level hooks/hooks.json + hooks/validate-claude-md.py
New deterministic enforcement of the 150-line cap. The validator
script reads the hook payload from stdin, extracts any referenced
CLAUDE.md path (supports both PostToolUse tool_input.file_path and
InstructionsLoaded path / file shapes), and exits 2 with stderr
feedback when the file is over 150 lines. Wired to both PostToolUse
on Write|Edit and InstructionsLoaded on every load_reason
(session_start, nested_traversal, path_glob_match, include, compact).
The cap is now enforced at every load *and* write, not only when the
guardian decides to run sync.
D. ContentGenerator.generate_rules_file() (skill/generator.py)
Emits path-scoped .claude/rules/*.md instruction files with name,
description, and paths: glob frontmatter. Claude loads these
lazily — only when accessing files matching the globs — so
file-type-specific guidance no longer has to live in the root
CLAUDE.md. Validates that paths is non-empty (ValueError otherwise).
E. AGENTS.md / .cursorrules / .windsurfrules interop
command/enhance-claude-md.md Phase 1 now lists which sibling
instruction files exist. ContentGenerator.generate_root_file() reads
project_context['existing_instruction_files'] and prepends an
## External Instructions section with @AGENTS.md (etc.) imports, so
repos already using other agent tooling can adopt ClaudeForge
without losing their existing instructions.
Smoke tests (all pass):
- Guardian hooks frontmatter parses as a dict with 4 events, each
carrying matcher + nested hooks array of {type, command} entries.
- hooks.json is valid JSON; PostToolUse matcher = Write|Edit;
InstructionsLoaded matcher covers all five load_reason values.
- validate-claude-md.py: small file -> rc 0, bloated file (200 lines)
-> rc 2 with stderr referencing the 150 cap, InstructionsLoaded
payload shape also handled, non-CLAUDE.md paths ignored, no stdin
-> rc 0.
- generate_rules_file emits valid frontmatter with paths glob and
raises ValueError when paths is empty.
- generate_root_file inserts @AGENTS.md and @.cursorrules imports
when existing_instruction_files lists them; omits the section
otherwise.
- Regression: large-fullstack root still 52 lines with chain imports
intact; all five sub-CLAUDE.md files in this repo still pass
validator (status = pass).
Docs:
- agent/CLAUDE.md updated to show the canonical hook shape and the
hook-driven validator wiring.
- skill/CLAUDE.md notes generate_rules_file and AGENTS.md interop.
- CHANGELOG.md documents all five changes under Unreleased.
