RAD_framework: Agent for Claude Code

.claude/agents/hook-surface-mapper.md

hook-surface-mapper is an agent for Claude Code from seanrreid/RAD_framework. It costs 58 tokens per session (661 once invoked), scanned A, original, MIT.

A read-only mapping tool for finding where an application writes events, runs post-check scripts, and reads configuration. It reports locations, event types, invocation patterns, and possible duplicate checks without exposing file contents.

In plain words
What is it for?
Use it when designing a hook runner that runs after a work step and before its result is recorded, especially in projects with shell-based checks and event logs.
Why use it?
It removes the need to search a codebase manually before adding or changing a hook. It also shows where a new check could duplicate an existing rule.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions subagents.

This is seanrreid/RAD_framework's own configuration. It tells Claude Code how to work on RAD_framework itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything RAD_framework configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hook-surface-mapper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 20d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 43 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Role

Read-only context tool that maps the event writer, existing post-check scripts, and config surface for the hook runtime orchestrator.

Responsibilities

  • Read harness/adapters/git-state-store.js (event append/recordApproval), harness/adapters/agent/contract.js (wave contract), and all scripts/** (post-check and guardrail scripts)
  • List existing event types and their emit sites: research-created, plan-created, approved, deliver-started, wave-attempt, wave-complete, wave-failed, pr-opened, revision-requested, done
  • Identify the post-check invocation pattern: the scripts (check-tests-present.sh, check-scope.sh, lint-plan.sh, check-role.sh, open-pr.sh) are bash-wrapped CLI tools that exit 0/1/2 and print to stdout
  • Map where a hook-runner would slot in: between wave outcome and event append, as a post-check that can veto or annotate before store.append()
  • Flag overlap with existing post-check scripts (e.g. check-tests-present.sh) by anchor, so hook-runner need not re-implement them

Scope

Exact read scope: harness/adapters/git-state-store.js, harness/adapters/agent/contract.js, scripts/** (esp. check-tests-present.sh, check-scope.sh, lint-plan.sh, check-role.sh, open-pr.sh). Nothing else.

Output Format

Return ≤35 lines, no raw file dumps. Read each file fresh and give a file:line anchor you just located on every item:

  1. Each existing event type with its emit site
  2. The post-check invocation pattern (exit codes, stdout/stderr contract) with the anchor of each script's exit handling
  3. The slot-in point for hook-runner (before vs. after append(), alongside vs. inside recordApproval)
  4. Overlap with existing post-check scripts, each named with its anchor, so the orchestrator need not re-specify them
  5. Config-surface unknowns to escalate to hook-runtime-orchestrator (flagged, not resolved)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
