epistemic-transaction — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited epistemic-transaction (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.

First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
Turn tasks into measured work. Investigation and implementation happen inside ONE measurement window, artifacts are recorded as you go, and learning compounds across boundaries.
PREFLIGHT → [noetic: investigate] → CHECK → [praxic: implement] → POSTFLIGHTUse this instead of EnterPlanMode for non-trivial work.
Decompose FIRST. A task added after the work is done is a self-graded checkbox, not a tracked unit.
empirica goals-create --objective "<title, ≤256>" --description "<markdown body>"
empirica goals-add-task --goal-id <ID> --description "<one unit of work>"
empirica goals-complete-task --task-id <ID> --evidence "commit abc123, tests pass"--description is the rich body (≤8000 chars, markdown — the extension renders it). Use it for anything substantive: why this exists, success criteria, links. Title-only goals are for genuinely trivial work.
--evidence is what makes a task grounded rather than self-reported. Tie it to a commit SHA, a test result, a file path — something deterministic.
Decompose into tasks when the work spans several files, investigation precedes implementation, or it will produce ≥2 commits. Anything you would otherwise track in a TodoWrite belongs here instead, where calibration can see it.
Lifecycle verbs, all reversible — a mis-close is recoverable, so you need not be perfect at the completion boundary:
empirica goals-create --objective "Future: X" --status planned # queued, not started
empirica goals-reopen --goal-id <ID> --reason "scope wasn't actually done"
empirica goals-archive --older-than 30 --apply # dry-run without --apply
empirica goals-list --status completed --include-archivedAdd --project-id <name-or-uuid> to log against a different project.
Sizing: bug fix or single function → 1 transaction. Feature across 2–3 files → 1–2. Cross-cutting concern → 2–3. "Redesign the system" → split further.

EOFwork_type: code|infra|research|release|debug|config|docs|data|comms|design|audit|remote-ops— scales evidence weights by source relevance. Use remote-ops for work the local Sentinel cannot observe (SSH, customer machines, remote config); POSTFLIGHT then returns calibration_status=ungrounded_remote_ops and self-assessment stands unchallenged.
work_context: greenfield|iteration|investigation|refactor — adjustsnormalization baselines for project maturity.
PREFLIGHT declares scope. If scope creeps, that is the signal to POSTFLIGHT and open a new transaction — not to quietly widen this one.
If you were already grounded before opening — you read the files first, which is the normal order — declare claims here with grounding read, or ran with the scope it measured over and the count it returned (a number: "count": 48). One such claim certifies the transaction and praxic proceeds with no CHECK at all. That is the correct path, not a shortcut.
Noetic work is ungated. Read, search and retrieve freely; individual Read / Grep / Glob / investigate calls need no batching.
Batch when you have ≥3 operations — the value is one merged result and fewer round-trips. It is NOT a Sentinel bypass, and calling it for a single read is misuse (the executor returns a warning field).

A bug you found in the code is a finding; you shipping it is a mistake. Something you have not verified is an assumption; something you know you don't know is an unknown. Defaulting everything to finding is the most common way this layer degrades — /artifact-graph has the full table.

EOFStructural artifact→goal edges are written for you. Assert the SEMANTIC ones: evidence, grounded_by, caused_by, invalidates, resolves, sourced_from. Most edges should reach artifacts from EARLIER transactions — if every edge joins two nodes you just created, you are building disconnected islands.
Single verbs remain right for one genuinely standalone artifact:

empirica mistake-log --mistake "..." --why-wrong "..." --prevention "..."

Skip the body when the title tells the whole story — over-describing trivia is its own anti-pattern.
--reversibility is exploratory|committal|forced. On mistake-log, --prevention is the load-bearing field: what future-you needs in order not to repeat it.
Register an external origin when the artifact came from something git blame cannot reach — an RFC, a paper, a vendor advisory, a customer call. Essential in Claude Desktop and other non-CLI surfaces, where most artifacts originate outside the repo.

EOFgrounding: `read` (opened the source) · `ran` (executed and observed — the strongest) · `retrieved` (from our OWN prior artifact — testimony, not observation) · `assumed` (acting without checking).
retrieved counts as weak deliberately. Our artifacts were true when written and age like any other prior; the same artifact can be solid grounding for one claim and stale for another, which is why the label belongs to the claim rather than the artifact.
Decision: proceed → write code (praxic, same transaction) · investigate → keep exploring (noetic, same transaction). CHECK does not end the transaction.
CHECK certifies; it does not unlock. Name the 2–3 claims the praxic work actually rests on. An empty CHECK is worse than none — it looks like diligence and carries nothing, and a CHECK filed seconds after PREFLIGHT with no artifact in between is exactly that.
Write code. Commit per completed task, not batched at the end — uncommitted work is invisible to grounded calibration. Keep logging: discoveries during implementation are findings, choices are decisions, and an approach that failed is a dead end even when the next one works.
Before closing, in this order:
invisible to calibration.
retracted. You hold the evidence *now*; a later gardening sweep will only have the age. stale means it merely aged; superseded --superseded-by <id>` means something replaced it.

EOFVerdicts: held · refuted · untested. Address a claim by index (1-based, declaration order) or id. The payload keys are verdict and evidence — note is accepted as an alias.
Falsifiers close here too, and they are not claims. A falsifiers array at PREFLIGHT or CHECK registers the OBSERVATION that would refute a belief you are acting on — {statement, query, falsifies: <artifact id>} — and unlike a claim it OUTLIVES the transaction, surfacing at every later PREFLIGHT until adjudicated. At POSTFLIGHT: {"falsifiers": [{"id": "f701c90f", "state": "tripped|survived|expired", "evidence": "...", "tripped_by": "..."}]}. `survived` needs evidence that you looked at the population; without it the verdict is recorded as expired, because nobody having looked is not the same as the belief holding. Leaving one open is legitimate — that is the mechanism working. empirica falsifier-list shows them.
Anything you don't adjudicate is recorded as `untested` and reported as a gap. That is the feature, not a penalty. refuted is rare, held is cheap, and "I acted on this and never checked it" is the one state a single know score cannot express. An untested claim is not a failure of the transaction; hiding it would be.
A refuted claim usually means a prior artifact is now false too — that is the moment to retract it, while you still hold the evidence.
POSTFLIGHT when: a coherent chunk is complete, confidence shifts, context changes, scope creeps, or 10+ turns have passed without measurement.
Runs automatically when domain and criticality were set at PREFLIGHT:
POSTFLIGHT response includes:

"intent": "address failures: tests",
"inherited_domain": "default",
"inherited_criticality": "medium"
}
}Tiered by cost: lint, complexity and git_metrics run at every POSTFLIGHT (~5s, ~80MB); tests run at goal completion.
Goal-per-transaction. Every transaction links to a goal; multi-step requests decompose at PREFLIGHT.
Commit-per-task. Not one batched commit at the end.
Artifact breadth. A session logging 25 findings and zero unknowns or assumptions did not have zero uncertainty — it failed to type it. Reported uncertainty with no unknown or assumption behind it is an unsupported claim.
Close before POSTFLIGHT. The window shuts; late artifacts are invisible.
Never split noetic and praxic across transactions. Investigating in one and implementing in another destroys the delta that IS the measurement — a PREFLIGHT that closes before acting has no outcome, and one that acts without a baseline has no start. It is the most common mistake and it looks tidy, which is why it persists.
Keep the window holdable. Five goals and fifteen files in one transaction makes the delta meaningless noise. One or two goals.
Mirror tasks to Claude Code Tasks on larger transactions so the user sees progress (goals-add-task → TaskCreate, goals-complete-task → TaskUpdate). Advisory — judge when visibility beats overhead.
Mesh work: ask when uncertain (cortex_collab, ungated), propose when convergent (ECO-gated), ack what you complete. Depth in /cortex-mailbox-send where your install has Cortex.
empirica goals-list # complete what's done
empirica resolve-artifacts - # batch: unknowns, assumptions, goals, findings
empirica delete-artifacts - # batch cleanup; preview by default, --apply to act
empirica update-artifacts - # METADATA only — impact, visibility, epistemic_sourceUnresolved artifacts accumulate as noise, and PREFLIGHT retrieves your prior artifacts to build context — so a clean graph is directly better context for the next transaction.
A wrong CLAIM takes `finding-resolve --kind retracted`; wrong METADATA takes `update-artifacts`. Do not resolve a true finding to fix a number. Claim text is immutable by design — retraction preserves the original wording and records that it failed.
A practice whose resolutions are almost all stale and almost never retracted has not been right about everything — it has stopped expressing its errors. A practice that cannot distinguish its ageing from its errors cannot calibrate on either.

The plan is a starting estimate, not a contract. Vectors shift as you learn, and measuring the delta between estimated and actual is what builds calibration — a PREFLIGHT that predicted badly is data, not a failure.
