pentester: Skill for Claude Code

.agents/skills/pentester-gen-report/SKILL.md

pentester-gen-report is a skill for Claude Code, Codex from fb0sh/pentester. It costs 50 tokens per session (442 once invoked), scanned A, original, MIT.

A guide for assembling and checking a security-engagement report from a fixed report template. It includes commands for adding findings, evidence, coverage, quality checks, delivery files, and retest results.

In plain words
What is it for?
Filling the report skeleton, validating the finished report, creating a client delivery bundle, and documenting what changed in a retest.
Why use it?
It reduces the risk of missing verified vulnerabilities, evidence, required sections, or differences from an earlier security review.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fb0sh/pentester's own configuration. It tells Claude Code and Codex how to work on pentester 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 pentester configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node .agents/schema/assemble-report.js ${ID} # paste under SKELETON 1.3 / 5 / 8.

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

pentester-gen-report 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 1mo 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.

What it actually says

gen-report

Procedure: .agents/phases/06-reporting.md
Fill interface (sole): .agents/REPORT-SKELETON.md
Optional wording: .agents/knowledge/reporting/report-wording-depth.md

# Assemble data sections (findings table · rollup · Evidence index · coverage)
node .agents/schema/assemble-report.js ${ID}      # paste under SKELETON 1.3 / 5 / 8

# Quality gate (Schema) — also fails if a Verified Vulnerability is omitted
node .agents/schema/check-report.js ${ID}

# Full contract + optional write seam
node .agents/schema/validate-target-schema.js ${ID} --strict-summary --check-report
node .agents/schema/validate-target-schema.js ${ID} --strict-summary --check-report --stamp-chain

# Client delivery bundle (attestation + index; Evidence indexed in place)
node .agents/schema/deliver.js ${ID}

# Remediation retest (when this run re-tests a prior engagement of the same Target):
# diff the baseline run → fixed / still-open / new, write retest.md
node .agents/schema/retest.js --baseline <prior-id> --current ${ID} --write
  1. assemble-report.js → data sections; fill SKELETON narrative in user language
  2. Read all manifests (incl. optional 1b) for context
  3. Quality + validate (consistency: every Verified Vulnerability appears in the Report)
  4. Stamp chain only when intentionally finishing phase 6
  5. deliver.js → delivery/ for the client
  6. Retest only: retest.js vs the baseline run → retest.md (see CONTEXT Retest)
Changes

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.
