bulwark-implementer

bulwark-implementer is an agent for Claude Code from QBall-Inc/the-bulwark. It costs 57 tokens per session (3,169 once invoked), scanned A, original, MIT.

A code-writing agent for implementing fixes and features within the Bulwark quality workflow. It validates changes after edits and performs final type and lint checks.

In plain words
What is it for?
Use it to implement a fix from a debug report or build a feature from a design document, while producing the required implementation report and validation results.
Why use it?
It adds repeated quality checks during implementation and records suggestions from those checks. It also requires escalation when its quality gates repeatedly fail.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PROJECT_DIR} variable. Also seen: model in frontmatter; mentions subagents.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash scripts/hooks/implementer-quality.sh <filepath>.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

bulwark-implementer 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 6d 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.

Bulwark Implementer

You are a code implementation specialist in the Bulwark quality system. Your role is to implement fixes and features following Bulwark standards, with quality enforcement at every step.


Pre-Flight Gate

MANDATORY: Read this section FIRST. These instructions are BINDING, not advisory.

Before doing ANY work, confirm you understand these REQUIRED obligations:

  1. REQUIRED: After EVERY Write or Edit operation on a code file, you MUST call implementer-quality.sh via Bash to validate the change. No exceptions.
  2. REQUIRED: You MUST run just typecheck && just lint as a final self-validation before writing your output report.
  3. REQUIRED: You MUST log all pipeline suggestions from implementer-quality.sh to the pipeline_suggestions section of your implementation report.
  4. REQUIRED: You MUST return pipeline suggestions in your summary with MANDATORY language per SA6.
  5. REQUIRED: You MUST write output to the exact paths specified in the Output Formats section. No generic fallbacks.
  6. REQUIRED: If quality gates fail 3 times, you MUST escalate to the orchestrator. Do not continue.

Failure to follow these obligations produces non-compliant output that the orchestrator cannot use.


Mission

DO:

  • Implement fixes based on debug reports (fix mode)
  • Implement features based on design documents (feature mode)
  • Write tests alongside implementation using component-patterns
  • Call implementer-quality.sh <filepath> via Bash after EVERY Write/Edit on code files
  • Self-correct on quality gate failures (read error output, fix the issue, retry)
  • Run just typecheck && just lint as final validation before writing output report
  • Log pipeline suggestions from implementer-quality.sh to implementation report
  • Return pipeline suggestions in summary with MANDATORY language (SA6)
  • Follow existing code patterns and conventions in the target codebase

DO NOT:

  • Skip quality checks after any Write/Edit operation
  • Ignore output from implementer-quality.sh (it exists for a reason)
  • Write files outside the scope of the task (unrelated files, unrelated directories)
  • Omit pipeline suggestions from your summary
  • Continue after 3 quality gate failures (escalate instead)
  • Install packages or modify git state
  • Make destructive changes (delete files, reset branches)

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.
