forensic-archival-listening

forensic-archival-listening is a skill for Claude Code, Codex from sonicfieldlabs/akouo. It costs 143 tokens per session (2,136 once invoked), scanned A, original, MIT.

A method for examining sound recordings as possible evidence, testimony, or historical records. It emphasizes what the recording can support and where uncertainty remains.

In plain words
What is it for?
Reviewing violence recordings, political testimony, surveillance audio, protest recordings, oral histories, legal audio, and historical archives.
Why use it?
It helps prevent unsupported conclusions from recordings that may be incomplete, damaged, edited, or missing important context.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

forensic-archival-listening scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

forensic-archival-listening

Purpose

forensic-archival-listening is the evidentiary ear of akoúō. It treats sound as trace, testimony, archive, memory, damage, silence, or reconstruction.

This mode is stricter than the others. It resists narrative completion, foregrounds mediation, and refuses to invent evidence.

When To Use

Use this skill for:

  • recordings of violence
  • political testimony
  • surveillance audio
  • field recordings used as evidence
  • historical archives
  • damaged tapes or degraded media
  • oral history
  • protest recordings
  • legal or quasi-legal contexts
  • sonic memory
  • speech as evidence
  • background sound as possible clue
  • authentication caution

Core Question

What can this sound testify, and where does testimony break down?

Conceptual Refinements

  • Sound can bear witness, but witness is not the same as proof; testimony depends on context, custody, mediation, and corroboration.
  • Background sound may reveal conditions of recording, law, space, or power, but it is not automatically a clue.
  • Archives decide what is preserved, named, damaged, excluded, and made listenable; treat archival authority as mediated.
  • Silence, dropout, remanence, hiss, edits, and degradation can matter, but their causes must remain uncertain unless inspected.
  • Legal or acoustic-jurisprudence contexts require special caution: do not convert sonic ambiguity into accusation, identity, sequence, or intent.
  • Under the /forensic command, claim permissions are overridden after the Evidence Ladder: interpreted and speculative are suppressed, and paralinguistic guesses (emotion, age, gender, identity) demote to undetermined.
  • Anchor evidentiary claims in time: since v0.6 each claim may carry a time_range; a claim without a time anchor is a claim about the whole recording and should say so. Invented temporal order is a named failure mode of model listeners.
  • Declare the apparatus and chain: capture device, codec history, edits, and the inspection toolchain belong in the v0.6 apparatus block; custody gaps belong in what_remains_hidden, not in silence.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
