broadside

broadside is a skill for Claude Code, Codex from HuginnIndustries/CodeCartographer. It costs 52 tokens per session (1,455 once invoked), scanned A, original, MIT.

A guide for interpreting a Broad-Side batch reconnaissance report, which is an automated first survey of a codebase using several analysis viewpoints.

In plain words
What is it for?
It helps read the combined report and decide where a more thorough interactive code review should focus.
Why use it?
It helps distinguish unverified leads from confirmed defects, since the batch checks do not build, test, or deeply inspect the repository.

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

broadside 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 3d 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 — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Broad-Side

Broad-Side is CodeCartographer's batch reconnaissance pass. It fires six analysis lenses — architecture, API surface, security, mechanical defect scan, convention extraction, and porting — at the repository as single-turn prompts over the OpenRouter Batch API (~50% of sync pricing, asynchronous, unattended), then synthesizes one cross-lens report. Results live under .codecarto/broadside/<run>/ alongside this file.

What Broad-Side findings are — and are not

Broad-Side findings are unverified scouting signals, not validated claims. Every lens is one shot: no cross-file traversal, no runtime verification, no builds, no tests, no follow-up questions. The batch model is cheap, not strong. Treat every finding as a lead with a file:line pointer that the interactive pipeline — or you — must confirm before it is a fact.

This is the division of labor: Broad-Side is cheap enough to run on any repo to decide where the expensive interactive run should spend its attention. It does not replace any phase; it tells phases where to look.

Reading a Broad-Side run

  1. Read synthesis.md first. It carries the executive summary, severity counts, the top cross-lens findings, and per-module risk levels.
  2. Read triage.md for the work order: each lead scored by impact × difficulty with a P0–P3 priority and an effort estimate. It is a starting point for re-verification, not a commitment — every item still needs confirmation against the source before work begins.
  3. Read the per-lens files behind anything that matters to your current phase:
    • architecture-*.json → the architecture phase's seed of prior knowledge
    • api-*.json → endpoints and data types (contracts/protocols phases)
    • security-*.json → auth, trust boundaries (defect-scan-semantic pass 5)
    • defect-*.json → mechanical defect leads (defect-scan-mechanical)
    • conventions-*.json → naming/idiom candidates for CONVENTIONS.md
    • porting-*.json → platform coupling (porting phase)
  4. run-meta.json records scope: which lenses ran, at what cost, with what coverage caps.

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.

broadside is a skill published in the GitHub repository HuginnIndustries/CodeCartographer (4 stars, last pushed 4d ago), licensed MIT. It adds 52 tokens to every session and 1,455 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
