What it does
Builtin Agent Skill is an agent skill from samugit83/redamon. Adding a built-in Agent Skill (an attack technique like ssrf, xxe, rce) that ships hardcoded in RedAmon: classified by the Intent Router, injected into the agent prompt, toggled per project, badged in the chat drawer. Nine layers across agentic and webapp, two of which fail with no error. Trigger: adding or editing a built-in attack skill; a new agentic/prompts/<skillidprompts.py; editing agentic/prompts/classification.py, agentic/prompts/init.py injectbuiltinskillworkflow, KNOWNATTACKPATHS in agentic/state.py…
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Penetration testing and Web application vulnerabilities. The repository describes itself as: Open-source, self-hosted AI penetration testing framework: maps your attack surface into a graph, autonomously exploits it from a Kali sandbox with human approval gates, and… The licence is MIT.
When your agent uses it
- Tasks that involve Penetration testing
- Tasks that involve Web application vulnerabilities
Example prompts
- “/builtin-agent-skill”
Requirements
- Python 3
- Node.js
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit d90c940. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dockerpython3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Builtin Agent Skill loads about 1.4k tokens when it runs. Until then it costs about 151 tokens; SKILL.md has 406 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Adding a built-in attack skill to the agent, Editing agent skill classification, phase injection, or the attack-skill UI
When to Use
- Adding a first-class attack technique the agent classifies and follows a workflow for.
For a user-uploadable workflow, use add-community-skill
instead. For a tool the agent calls, use agentic-tool-integration.
For per-skill tunable defaults, use project-settings-cascade.
Critical Rules
- ALWAYS add the skill id to
KNOWN_ATTACK_PATHSin agentic/state.py. It is the Pydantic validator's allowlist; miss it and the classifier's output is rejected at runtime even though every other layer is wired. - NEVER skip layers 8 and 9 (the chat-drawer layers). They live in webapp and
produce no error when forgotten: the skill classifies and badges, but the
drawer tooltip and one-click example prompts are silently missing. Layer 8 =
BUILT_IN_SKILLSin attack-skills/available/route.ts; Layer 9 = aSESubGroupin suggestionData.ts. - NEVER let classification keywords overlap an existing skill. Every enabled built-in competes for the same user message; overlapping keywords (e.g. saying "SQL" in an SSRF section) make both skills mis-route. Disambiguate in the "Key distinction" line of the section in classification.py.
- ALWAYS gate the workflow on the required tool inside
_inject_builtin_skill_workflow()(agentic/prompts/init.py:509):and "<tool>" in allowed_tools. Without the guard the agent gets instructions for a toolTOOL_PHASE_MAPblocks in that phase. - NEVER assume existing projects inherit the new skill.
builtInis a strict has-key check; existing projects need a jsonb update toattackSkillConfig. - ALWAYS add a registry entry for a per-skill tunable that became a
Projectcolumn in recon_settings/registry.yaml. A test walkingPrisma.ProjectScalarFieldEnumfails until every column has one. Draft it withpython3 tooling/scripts/extract_recon_registry.py, edit it, thenpython3 recon_settings/build.py. An attack-skill tunable is ordinarymcp: settabletuning now, bounded by its registry entry and gated at scan start byroeForbiddenCategories,roeForbiddenToolsandroeAllowDosrather than by being unreachable. Give ittraffic: activeso it joins the queued-job fingerprint, androe_capped: trueif its unit isrps. - Pick the snake_case id once and use that exact literal in all 9 layers.
grep -rn "<skill_id>" webapp/src agenticmust show it everywhere before you rebuild (an existing id likecve_exploitspans ~38 files).
