What it does
Tracing Knowledge Lineages is an agent skill from sandgardenhq/sgai. Understand how ideas evolved over time to find old solutions for new problems and avoid repeating past failures. When problem feels familiar but can't remember details. When asked "why do we use X?". Before abandoning an approach, understand why it exists. When evaluating "new" ideas that might be revivals. When past attempts failed and need to understand why. When tracing decision genealogy.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Sandgarden AI Software Factory.
Example prompts
- “t remember details. When asked”
- “/tracing-knowledge-lineages”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Check decision records (ai_working/decisions/, docs/decisions/, ADRs)
- Search conversations (skills/collaboration/remembering-conversations)
- Git archaeology (git log --all --full-history -- path/to/file)
- Ask the person who wrote it (if available)
What it can do on your machine
Read from SKILL.md and the folder at commit 9efbb7b. 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:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use 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
Tracing Knowledge Lineages loads about 1.8k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 659 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 659 words (~1,821 tokens).
“Ideas have history. Understanding why we arrived at current approaches - and what was tried before - prevents repeating failures and rediscovers abandoned solutions.”
