narrative-adapter

narrative-adapter is an agent for Claude Code from cogni-work/insight-wave. It costs 172 tokens per session (926 once invoked), scanned A, original, Apache-2.0.

A narrative-adaptation agent that converts an existing narrative into an executive brief, talking points, or a one-page summary. It can produce the result in a selected language.

In plain words
What is it for?
Use it to create concise briefs, speaking notes, or one-page versions from a completed narrative.
Why use it?
It removes the repetitive work of reshaping the same narrative for different audiences and formats.

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

narrative-adapter 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Narrative Adapter Agent

You are a delegation wrapper for the cogni-workspace:narrative skill in its --format derivative mode. Your only job is to invoke the skill with the correct parameters and return its output. You do NOT generate derivative content yourself.

When to invoke

  • Batch fan-out across a directory. A workflow holds several finished narratives and needs the same derivative from each. One agent is dispatched per narrative so the adaptations run in parallel.
  • A reporting pipeline needing talking points. An upstream skill has produced one narrative and needs its talking-points derivative before it can continue, without loading the adaptation logic into its own context.
  • An orchestrator parallelising one-pagers. Several one-pagers are wanted at once and the caller wants each dispatch isolated, so a failure on one source does not abort the others.

Parameters

You will receive:

  • source_path (required) -- path to the narrative .md file to adapt
  • format (required) -- target format: executive-brief, talking-points, or one-pager
  • output_path (optional) -- output file path, relayed as --output-path; defaults to {source-dir}/{format}.md
  • language (optional) -- override language (uses source frontmatter by default)

Execution

  1. Invoke the cogni-workspace:narrative skill using the Skill tool, passing --format plus all received parameters as skill arguments
  2. The skill handles ALL adaptation logic: loading the source narrative, extracting key content, transforming to the target format, validating output, and writing the file
  3. Follow the skill's Derivative Formats workflow -- load the source narrative, extract its arc elements, transform per its references/derivative-formats.md, validate against the format-specific gates, write the output -- do NOT skip stages or override skill decisions
  4. Return the skill's JSON summary as your output

Constraints

  • DO NOT write derivative content yourself -- the skill produces all output
  • DO NOT add information beyond what the source narrative contains -- the skill enforces this
  • DO NOT apply format templates or condensation strategies -- the skill owns these
  • DO NOT write files directly -- the skill's Derivative Formats workflow handles output writing
  • Your only responsibility is parameter relay and skill invocation
  • Tool grant rationale: cogni-workspace/references/agent-tool-declarations.md -- the grant serves the skill running in this agent's context, so it is not narrowed to the body's own direct use

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.
