What it does

Knowledge Ops is an agent skill from Mark393295827/third-brain-v7-skills. Use when an Obsidian knowledge system needs classification, deduplication, retrieval, synchronization, debt queues, or governed Agent/Wiki promotion.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/storage-governance.md`).

It sits in Knowledge Management, covering Data cleaning and LLM wikis. It works with Obsidian. The repository describes itself as: agent wiki +engineering skills. The licence is MIT.

When your agent uses it

  • An Obsidian knowledge system needs classification
  • Synchronization
  • Governed Agent/Wiki promotion

Example prompts

  • “/knowledge-ops”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

  1. Classify: assign each item to execution state, quick memory, durable wiki, optional retrieval index, or governance state.
  2. Search first: exact path/title, wikilinks, canonical URL/source id, and lexical search before semantic retrieval.
  3. Deduplicate: compare source identity, normalized URL, hash when available,
  4. Store: write to the canonical Markdown layer, update indexes/maps, preserve immutable sources, and queue unresolved debt.
  5. Retrieve: return paths and match reasons; load only the top evidence-bearing pages within context budget.
  6. Sync: update optional indexes from canonical files and record indexed, skipped, removed, or failed items.
  7. Verify: read after write, check links/source refs, rerun exact-identity
  8. Promote: require two durable supports or one strong source plus local verification, a bounded execution contract, preserved…

What it can do on your machine

Read from SKILL.md and the folder at commit 5a64514. 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

Knowledge Ops loads about 1.6k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 41 tokens; SKILL.md has 750 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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.

Knowledge Operations

<skill_contract> <input>Vault root, operation, scope, canonical-store rules, permissions, destination, and execution budget.</input> <output>Verified classification, retrieval, deduplication, synchronization, audit, or governed promotion changes with receipts.</output> <done>Canonical Markdown remains authoritative, provenance and immutability are preserved, and representative checks pass.</done> <non_goals>Using vectors as canonical storage, silent provenance merges, automatic semantic rewrites, or one-signal rule promotion.</non_goals>

Operate the wiki as durable disk and governance layer. Markdown pages hold understanding and provenance; indexes, memory, vectors, and dashboards are replaceable access paths.

Usage Template

Provide: vault root, operation (organize, deduplicate, retrieve, sync, audit, promote), scope, destination, permissions, and budget. Load references/storage-governance.md only when designing layers or promotion queues.

Workflow

<intake>

Resolve configured paths and identify the canonical store, immutable sources, active execution truth, optional retrieval indexes, and governance queues. Record file counts, scope, and write authority before mutation.

</intake>

<unknowns_gate>

If canonical ownership, vault identity, or merge authority is ambiguous, return NEEDS_INPUT. Treat semantic similarity as a review signal, not proof that two notes or sources are equivalent.

</unknowns_gate>

<execute>

knowledge-ops owns cross-corpus organization, identity reconciliation, retrieval/index state, promotion queues, and knowledge-debt governance. It does not replace wiki-ingest as the owner of a single source-to-candidate transaction, and it does not replace wiki-lint as the read-only health auditor.

  1. Classify: assign each item to execution state, quick memory, durable wiki, optional retrieval index, or governance state.
  2. Search first: exact path/title, wikilinks, canonical URL/source id, and lexical search before semantic retrieval.
  3. Deduplicate: compare source identity, normalized URL, hash when available, claims, and provenance; merge compiled notes only with traceable reasons. Under concurrent writers, stage the candidate, acquire or verify one source identity key, and recheck immediately before and after promotion.
  4. Store: write to the canonical Markdown layer, update indexes/maps, preserve immutable sources, and queue unresolved debt.
  5. Retrieve: return paths and match reasons; load only the top evidence-bearing pages within context budget.
  6. Sync: update optional indexes from canonical files and record indexed, skipped, removed, or failed items.
  7. Verify: read after write, check links/source refs, rerun exact-identity search, and run representative retrieval queries. If a race produced two candidates, keep one canonical source, repoint derived locators, and emit a reconciliation receipt without rewriting prior evidence.
  8. Promote: require two durable supports or one strong source plus local verification, a bounded execution contract, preserved approvals/provenance, and a cheap objective check.

Use idempotency keys for machine append operations: derive the key from operation, canonical source identity, target, and run/batch id; append only when the key is absent. Repeated schedules and retries must converge to the same canonical files and one logical receipt.

Automate deterministic counts and index refreshes only. Semantic rewrites, contradiction resolution, and rule promotion remain supervised.

</execute>
<evaluate>

Compare pre/post counts, inspect merge samples, replay retrieval queries, and verify no immutable source changed. A sync is partial if any canonical file is unindexed; retrieval quality is unproven without representative queries.

</evaluate>

<state_contract>

Persist {run_id, status, attempt, budget, evidence, unknowns, last_error, next_action} plus canonical paths, operation scope, source identity/idempotency keys, writer lease or compare-and-set evidence, file ledger, merge/reconciliation decisions, debt queues, index receipts, retrieval tests, and promotion candidates. Keep source and merge history append-only.

</state_contract>

Failure Protocol

  • NEEDS_INPUT: ownership, merge semantics, or vault identity is unclear.
  • BLOCKED_PERMISSION: a required store or index is inaccessible; continue read-only where useful.
  • VERIFY_FAILED: write, link, sync, or retrieval check fails; preserve canonical state and queue repair.
  • NO_PROGRESS: repeated organization changes no objective metric; stop and report the governing bottleneck.
  • BUDGET_STOP: persist coverage and remaining queue; make no whole-vault claim.

Output Contract

Return status, result (organized/retrieved/synced items and decisions), evidence (counts, paths, receipts, queries), unknowns, and next_action with owner and check.

Edge Cases

  • Two notes share a title but cite different sources and mechanisms: keep both until semantic review establishes a safe merge.
  • Two workers pass the same exact-URL preflight and stage separate source notes: recheck identity at commit, choose one canonical path, repoint derived links, and record the race; do not leave two canonical sources.
  • Vector retrieval misses an exact concept: verify the Markdown path and index state; do not conclude the knowledge is absent.

Success Metrics

  • Canonical Markdown remains retrievable with provenance intact.
  • Duplicates, stale metadata, weak links, and contradictions enter explicit queues.
  • Every promotion candidate includes support, owner, budget, stop rule, and cheap check.

Quality Gates

  • Canonical store and immutable boundaries are explicit.
  • Exact/lexical retrieval precedes optional semantic retrieval.
  • Merge and sync decisions have receipts.
  • Concurrent writes converge by source identity and append idempotency key.
  • No semantic rule is promoted without the promotion gate.
