What it does
Trailmark Summary is an agent skill from trailofbits/skills, published by the product's own GitHub organization. Runs a Trailmark summary analysis on a codebase. Returns auto-detected languages, entry point count, and dependency list. Use when vivisect or galvanize needs a quick structural overview. Triggers: trailmark summary, code summary, structural overview.
Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including assets (for example `agents/openai.yaml`).
The repository describes itself as: Trail of Bits Claude Code skills for security research, vulnerability detection, and audit workflows. The licence is CC-BY-SA-4.0.
When your agent uses it
- Galvanize needs a quick structural overview
Example prompts
- “/trailmark-summary”
Requirements
- Python 3
- Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Detected languages from Step 2
- Entrypoints: line from the summary output
- Dependencies: line from the summary output
What it can do on your machine
Read from SKILL.md and the folder at commit 82fe822. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
BashReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uvpython3pipgit
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, pip and git, 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
Trailmark Summary loads about 926 tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 374 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

The automated check noted patterns worth knowing about, such as sudo or a known installer.

allowed-tools: Bash, Read, Grep, Glob
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.

Trailmark Summary
Runs trailmark analyze --language auto --summary on a target directory.
This is a v0.2-safe workflow; do not require Trailmark 0.4.0 just to produce a
summary.
When to Use
- Vivisect Phase 0 needs a quick structural overview before decomposition
- Galvanize Phase 1 needs detected languages and entry point count
- Quick orientation on an unfamiliar codebase before deeper analysis
When NOT to Use
- Full structural analysis with all passes needed (use
trailmark-structural) - Detailed code graph queries (use the main
trailmarkskill directly) - You need hotspot scores or taint data (use
trailmark-structural)
Rationalizations to Reject
| Rationalization | Why It's Wrong | Required Action |
|---|---|---|
| "I can read the code manually instead" | Manual reading misses parser-based language detection, dependency data, and entry point enumeration | Install and run trailmark |
| "Language detection doesn't matter" | Wrong language selection produces empty or partial analysis | Use Trailmark's parser-based detection or --language auto |
| "Partial output is good enough" | Missing any of the three required outputs (detected languages, entry points, dependencies) means incomplete analysis | Verify all three are present |
| "Tool isn't installed, I'll skip it" | This skill exists specifically to run trailmark | Report the installation gap instead of skipping |

Execution
Step 1: Check that trailmark is available.
trailmark analyze --help 2>/dev/null || \
uv run trailmark analyze --help 2>/dev/nullIf neither command works, report "trailmark is not installed"
and return. Do NOT run pip install, uv pip install,
git clone, or any install command. The user must install
trailmark themselves.
Optionally record the version if the installed build supports it:
trailmark --version 2>/dev/null || uv run trailmark --version 2>/dev/null || trueDo not fail if the version command is missing; older v0.2.x builds may still support the summary workflow.
Step 2: Detect languages with Trailmark's parse API.
python3 - "{args}" <<'PY'
import json
import sys
try:
from trailmark.parse import detect_languages # canonical location since 0.3.x
except ModuleNotFoundError:
# v0.2.x predates trailmark.parse; the same function lives in query.api
from trailmark.query.api import detect_languages
print(json.dumps(detect_languages(sys.argv[1])))
PYIf the import fails, rerun the same snippet with uv run --with trailmark python - "{args}".
If the result is [], report "Trailmark found no supported languages under
target" and return.
Step 3: Run the summary with auto-detection.
trailmark analyze --language auto --summary {args} 2>&1 || \
uv run trailmark analyze --language auto --summary {args} 2>&1Step 4: Verify the output.
The output must include ALL THREE of:
- Detected languages from Step 2
Entrypoints:line from the summary outputDependencies:line from the summary output
If any are missing, report the gap. Do not fabricate output.
Return the detected language list plus the full Trailmark summary output. If a version string was available, include it in the returned metadata.
