At a glance
Compute the blast radius of modifying a symbol through transitive graph impact.
- Works in 4 steps: Identify the symbol name → Run impact analysis → Interpret the risk rating → …
- The user asks about blast radius
- SKILL.md covers Overview, Quick Reference, Required parameters — get_impact and Steps, plus 3 more sections
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Memtrace Impact is an agent skill from syncable-dev/memtrace-public. Compute the blast radius of modifying a symbol through transitive graph impact. Use when the user asks about blast radius, impact, what breaks, risk, upstream callers, downstream dependencies, or consequences of modifying a symbol, before or during source-code changes. Do not use Grep or manual reference search; Memtrace computes transitive graph impact. For a full risk-rated plan covering a multi-part change, use memtrace-change-impact-analysis.
Its SKILL.md is about 990 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 Development. The repository describes itself as: Structural memory for AI coding agents. Bi-temporal graph, MCP-native, zero LLM calls. Cursor · Claude Code · Codex · DeepSeek Harness · Hermes · VS Code · Windsurf.
When your agent uses it
- The user asks about blast radius
- Upstream callers
- Downstream dependencies
- Consequences of modifying a symbol
Example prompts
- “/memtrace-impact”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Identify the symbol name
- Run impact analysis
- Interpret the risk rating
- For diff-based analysis
What it can do on your machine
Read from SKILL.md and the folder at commit 3a3084d. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are json).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Memtrace Impact loads about 986 tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 363 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 363 words (~986 tokens).
“Compute the blast radius of changing a specific symbol. Traces upstream (what depends on this) and downstream (what this depends on) through the knowledge graph to quantify risk before making modifications.”
