What it does
Memtrace Decision Memory is an agent skill from syncable-dev/memtrace-public. Use Cortex decision memory through the normal Memtrace MCP tools. Trigger for free-text questions about what was decided, chosen, rejected, banned, or established as a convention; for why a symbol exists or which contracts constrain it; for whether a known decision held, drifted, or was violated; and for the implementation arc behind a decision. Use before non-trivial edits, refactors, deletions, or re-picking a library, pattern, architecture, or subsystem behavior. Routes internally across recalldecision…
Its SKILL.md is about 1.9k 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, covering Refactoring and MCP servers. It works with Git and Model Context Protocol. 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
- Free-text questions about what was decided
- Established as a convention
- For why a symbol exists
- Which contracts constrain it
Example prompts
- “/memtrace-decision-memory”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- If you only have a name/free-text target, recall_decision("") first.
- If you have a symbol_id, why_is_this_here(symbol_id) → the governing decision, if any.
- governing_contracts(symbol_id) → constraints that must survive a rewrite.
- If a decision governs it → verify_intent(decision_id) to see if it still holds.
- CannotProve on all checks ≠ safe to delete — confirm with memtrace-impact (blast radius) and the user.
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.
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 Decision Memory loads about 1.9k tokens when it runs. Until then it costs about 163 tokens; SKILL.md has 758 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 758 words (~1,928 tokens).
“This is the rationale layer of the codebase. memtrace-first answers what the code is and how it's wired (symbols, calls, git, blast radius). Decision memory answers why it is the way it is, what we already decided, and whether that…”
