Skill for building memory by agent itself
SaferSkills independently audited memory-cli (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

memory-cli benchKeep this command surface stable. Improve retrieval internals without changing command names or JSON output shape unless the user explicitly asks for a breaking contract change.
Treat durable memory as tested retrieval behavior. Retrieval unit tests are gates and regression contracts, not the runtime retrieval system.
Build or update the retrieval system by distilling the facts and keyword/key-phrase intent expressed by the tests into the project's chosen implementation. That implementation may be JSON structure, code paths, if/else rules, indexes, caches, databases, vector stores, or another suitable design. The tests prove the behavior; they should not be the data source that search depends on at runtime.
Keep runtime retrieval resources separate from retrieval unit-test resources. A portable memory-cli search package must run with only runtime code, runtime memory data, config, and optional generated runtime indexes. It must not read from tests/, test fixtures, test-case files, benchmark fixtures, unit-test assertions, or any other test-only resource.
Use a layout like:
src/ or memory_cli/: CLI and retrieval implementation.memories/: durable runtime memory records used by search, list, show, conflict checks, and indexes.test-cases/: retrieval unit-test queries and assertions used by test and bench.indexes/ or .memory-index/: optional generated runtime retrieval artifacts.tests/ or fixtures/: ordinary project tests and fixtures.search may read only runtime memory records and runtime indexes. test and bench may read test-cases/ and then call the public CLI/search path. If a candidate file contains both memory content and retrieval tests, add must split it into runtime memory data under memories/ and test-only assertions under test-cases/.

memory-cli command is available:uv tool install -e . from the copied project.npm link from the copied project, or use node src/cli.js ... during development.npm install && npm run build && npm link, or use npm test during development.memory-cli search "<keyword-or-key-phrase>" ["another-keyword-or-key-phrase"...]Use keyword and key-phrase queries for retrieval unit tests and normal searches. Multiple keyword arguments may match the same memory. When search receives multiple keyword arguments, it returns one result group per input keyword in the same order.

memory-cli benchRead references/memory-test-contract.md before adding, reviewing, migrating, or changing memory records. Use it for the JSON schema, review rules, conflict handling, and test passing rule.
When extracting new memory from conversations, documents, project history, or external source material, read references/memory-extraction-guide.md. Use it to turn source material into answerable, testable memories with entities, aliases, time/place facts, relationships, state changes, and keyword/key-phrase retrieval tests.
When extracting memories, avoid topic-only summaries. Preserve exact answer-bearing details, item-level list information, reusable preferences, cross-context retrieval terms, and current values for changing facts.
Retired memories stay on disk for audit history but must not appear in normal search results, conflict checks, tests, or benchmarks.
Use priority to decide ranking and failure severity. Search results must be sorted by priority first, then by retrieval score as a tie-breaker:
100 = identity, hard constraints, long-term user preferences
80 = important project decisions
60 = common habits and workflow preferences
40 = temporary but still useful context
20 = low-value historical notesRespect the project's config. A typical config treats failed memories at or above blocking_failure as blocking.
Start with the simplest implementation that passes tests. It is acceptable for early memory projects to use JSON scans or hard-coded logic.
Do not implement retrieval by reading unit-test assertions as the live search corpus. Treat fields such as queries and must_include as test metadata stored outside runtime memory records unless the project explicitly defines separate runtime aliases or keywords. Candidate queries should be keyword or key-phrase test inputs, not full prompts. Use tests to drive and verify the implementation, then store or encode the resulting memory facts in the system's runtime structures.
When the test suite grows or bench exceeds budget, read references/retrieval-optimization-guide.md and improve internals without changing the CLI output contract.
Do not delete or weaken high-priority memory tests to hide retrieval problems.
