report-writing

Bug bounty report writing for H1/Bugcrowd/Intigriti/Immunefi — report templates, human tone guidelines, impact-first writing, CVSS 3.1 scoring, title formula, impact statement formula, severity decision guide, downgrade counters, pre-submit checklist. Use after validating a finding and before submitting. Never use "could potentially" — prove it or don't report.

Quality

Content

78%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

Highly actionable and disciplined content — executable templates, exact request/response examples, and explicit triager-focused rules with a validation checklist. The main weakness is structure: a ~500-line monolith where per-platform templates and CVSS scoring references should be split into one-level-deep reference files, plus minor redundancy between overlapping sections.

Suggestions

Move the four platform-specific templates (HackerOne, Bugcrowd, Intigriti, Immunefi) into references/ files (e.g., references/hackerone-template.md) and keep only a short template-selection table inline in SKILL.md.

Move the CVSS 3.1 metric tables and the CVSS 4.0 quick reference into a references/cvss-scoring.md file, keeping just the 'typical scores by bug class' table inline for quick severity anchoring.

Deduplicate the 'Steps to Reproduce Format' section by folding its two-account setup pattern into the template guidance once, and add an explicit feedback loop for the pre-submit checklist (what to fix and re-check when an item fails).

DimensionReasoningScore

Conciseness

The body is dense and prescriptive — templates, tables, formulas, checklists — with almost no explanation of concepts Claude already knows. Minor trimming is possible: the 'Steps to Reproduce Format' section largely duplicates material already shown in the platform templates, and 'Severity Self-Assessment' overlaps the 'Severity Decision Guide'. Efficient overall, so 4 rather than 3 or 5.

4 / 5

Actionability

Fully copy-paste-ready guidance: four complete platform-specific report templates, exact HTTP requests and JSON responses, concrete good/bad title examples, verbatim downgrade counter-phrases, CVSS vectors with a calculator URL, and a 12-item pre-submit checklist — the common cases are covered end to end.

5 / 5

Workflow Clarity

The report-writing process is clearly implied by section order (title formula → template → CVSS → severity → pre-submit checklist), and the 60-second pre-submit checklist is an explicit validation checkpoint, plus the Persistence Rule defines where outputs land. It falls short of a 5 because there is no explicit end-to-end assembly sequence or feedback loop (e.g., what to do when a checklist item fails), and it stays above 3 because a concrete checkpoint and output-location rule are present.

4 / 5

Progressive Disclosure

The body has clear section headers, but it is a ~500-line single file with no references/ directory: the four platform-specific templates (H1/Bugcrowd/Intigriti/Immunefi) and the CVSS 3.1/4.0 reference tables are content that clearly belongs in separate reference files, inlined into SKILL.md. This matches 'some structure, content that should be separate is inline' (3) rather than 2, since navigation via headers is good.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description: specific, third-person, explicitly scoped to four named platforms, with a concrete capability list and an explicit when-to-use clause. The only gap is slight synonym coverage in trigger terms (e.g., 'write-up', 'HackerOne' spelled out).

DimensionReasoningScore

Specificity

The description enumerates many concrete capabilities — 'report templates, human tone guidelines, impact-first writing, CVSS 3.1 scoring, title formula, impact statement formula, severity decision guide, downgrade counters, pre-submit checklist' — giving comprehensive coverage of the skill's function with no vague filler.

5 / 5

Completeness

Both questions are explicitly answered: 'what' via the concrete capability list, and 'when' via the explicit clause 'Use after validating a finding and before submitting', which states a concrete trigger condition rather than leaving timing implied.

5 / 5

Trigger Term Quality

Good natural keyword coverage ('bug bounty', 'report', 'CVSS', 'severity', 'submit', plus platform names H1/Bugcrowd/Intigriti/Immunefi), but a few common variations are missing such as 'write-up', 'disclosure', or 'HackerOne' spelled out. Not clearly below or above the 4 anchor, so 4 rather than 3 or 5.

4 / 5

Distinctiveness Conflict Risk

The description carves out a clear niche — bug bounty report writing for four named platforms — with trigger terms unlikely to overlap with general writing, documentation, or vulnerability-discovery skills.
