ctf-web

Provides web exploitation techniques for CTF challenges. Use when the target is primarily an HTTP application, API, browser client, template engine, identity flow, or smart-contract frontend/backend surface, including XSS, SQLi, SSTI, SSRF, XXE, JWT, auth bypass, file upload, request smuggling, OAuth/OIDC, SAML, prototype pollution, and similar web bugs. Do not use it for native binary memory corruption, reverse engineering of standalone executables, disk or memory forensics, or pure cryptanalysis unless the web flaw is still the main path to the flag.

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.

The content is a well-organized routing guide with executable quick-start commands and excellent progressive disclosure into reference files. Its main weakness is mild redundancy across the recon/pattern/chain sections and the lack of explicit validation checkpoints in the workflow.

Suggestions

Consolidate the overlapping bug-family catalogs (Fast Pattern Map, Common Chain Shapes, High-Value Recon Checks, First Questions to Answer) into a single routing section to reduce redundancy and token cost.

Add an explicit validation/verify step to the First-Pass Workflow (e.g., 'Confirm the primitive works against a benign target before chaining') so the sequence has a concrete checkpoint.

Tighten or paginate the 24-entry Additional Resources list, or move per-entry annotations into the referenced files, keeping the index a short lookup table.

Dimension	Reasoning	Score
Conciseness	Mostly lean and assumes competence (no padding explaining what XSS/SQLi is), but several sections re-catalog the same bug families (Fast Pattern Map, Common Chain Shapes, First Questions, High-Value Recon, Additional Resources) and the 24-entry annotated resource list adds length that could be trimmed.	4 / 5
Actionability	Quick Start Commands gives copy-paste-ready curl/ffuf/sqlmap/flask-unsign/SSTI probes and prerequisites give exact install commands, but most are illustrative templates with placeholders and the deepest techniques live in referenced files rather than inline.	4 / 5
Workflow Clarity	The First-Pass Workflow is a clear 5-step ordered sequence with explicit sequencing guidance ('only then dive', 'smallest proof first'), but validation/verification checkpoints are implicit rather than called out as explicit feedback loops.	4 / 5
Progressive Disclosure	The body is a well-structured overview that routes to ~24 one-level-deep reference files via an annotated Additional Resources catalog, a Fast Pattern Map routing table, and a Deep-Dive Notes pointer, making navigation easy.	5 / 5

Description

100%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.

The description is specific, trigger-rich, and fully answers both what the skill does and when to use it, with explicit boundary guidance that sharply reduces conflict with sibling CTF skills. It is a model web-exploitation routing description.

Dimension	Reasoning	Score
Specificity	Names the web-exploitation domain and enumerates many concrete bug/action categories (XSS, SQLi, SSTI, SSRF, XXE, JWT, auth bypass, file upload, request smuggling, OAuth/OIDC, SAML, prototype pollution), giving comprehensive coverage rather than vague language.	5 / 5
Completeness	Explicitly answers both 'what' ('Provides web exploitation techniques for CTF challenges') and 'when' ('Use when the target is primarily an HTTP application, API...'), with concrete trigger phrases and explicit 'Do not use' boundary guidance.	5 / 5
Trigger Term Quality	Includes the natural terms users say for web CTFs (XSS, SQLi, SSTI, SSRF, XXE, JWT, OAuth/OIDC, SAML, file upload, request smuggling) plus synonyms and surface types (HTTP application, API, browser client, template engine).	5 / 5
Distinctiveness Conflict Risk	Occupies a clear CTF-web niche and adds explicit carve-outs against native binary RE, pwn, crypto, and forensics skills, minimizing the chance of triggering for the wrong skill.	5 / 5
