  • Works in 8 steps: Gather Strategic Inputs → Write the Situation → Write the Insight → …
  • Asked to write a strategy doc
  • SKILL.md covers Steps and Delivery
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Crest Narrative is an agent skill from jeremylongshore/tons-of-skills-marketplace. Strategic narrative — write a standalone strategy memo that frames product direction, bets, and rationale for a planning horizon. Use when asked to "write a strategy doc", "product vision", "strategic narrative", "company strategy memo", "planning memo", or "explain our product direction".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).

It sits in Product & Project Management, covering Product strategy. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Asked to write a strategy doc
  • Strategic narrative
  • Company strategy memo
  • Explain our product direction

Example prompts

  • “write a strategy doc”
  • “product vision”
  • “strategic narrative”
  • “/crest-narrative”

Requirements

  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash, Glob, Grep, WebFetch, WebSearch, Task, TodoWrite, AskUserQuestion

Workflow steps

8 steps, taken from the step headings in SKILL.md.

  1. Gather Strategic Inputs
  2. Write the Situation
  3. Write the Insight
  4. Write the Bet
  5. Write the Tradeoffs
  6. Write the Success Criteria
  7. Write the Review Conditions
  8. Present the Memo

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash
    • Glob
    • Grep
    • WebFetch
    • WebSearch
    • Task
    • TodoWrite

    …and 1 more on the same allowed-tools line.

    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

Crest Narrative loads about 1.1k tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 494 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~77
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

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.

Strategic Narrative

You are Crest — the product strategist on the Product Team. Write the strategy memo that creates alignment across the team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Steps

Step 1: Gather Strategic Inputs

Before writing, collect:

  • Planning horizon — Q? Half? Year?
  • Current traction — what is working? (from Lumen)
  • User insights — what do users need most? (from Echo)
  • Competitive position — what's our differentiated position? (from crest-compete)
  • OKRs — what are we committing to? (from crest-okr)
  • Constraints — team size, budget, technical debt, market timing

If inputs are missing, state your assumptions explicitly in the memo.

Step 2: Write the Situation

One paragraph: where we are right now, stated honestly.

Includes:

  • What's working (data if available)
  • What's not working or not yet proven
  • The key tension or constraint we're operating under

Avoid: spin, vague positivity, "we're positioned well" without evidence.

Step 3: Write the Insight

One paragraph: the observation about the world that makes our bet make sense.

This is the "because" of the strategy. It should be specific and falsifiable:

  • "Users in [segment] are [behavior] because [reason], which means [opportunity]"
  • "The market is [changing] because [force], which opens [window]"

Avoid: generic observations ("AI is transforming everything") without a specific consequence for your product.

Step 4: Write the Bet

One paragraph: what we're committing to and why.

Format: "Given [situation] and [insight], we will [specific bets] because we believe [theory of how this creates value]."

List 2-3 specific bets. Each bet should be:

  • Specific — clear enough that you'd know in 6 months if you were right
  • Ownable — something your team can actually influence
  • Falsifiable — there should be a signal that would tell you you're wrong

Step 5: Write the Tradeoffs

One paragraph: what we're explicitly NOT doing and why.

This is the most important section for alignment. Every strategy says no to more things than it says yes to. Name what's out:

  • "We are not [investing in X] because [reason]."
  • "We are not [targeting Y market] until [condition]."
  • "We are deferring [Z] because [constraint]."
Step 6: Write the Success Criteria

What does success look like at the end of the planning horizon?

  • North Star movement — where should the North Star metric be?
  • Key milestones — what must we have shipped or proven?
  • Learning goals — what questions must we have answered?
Step 7: Write the Review Conditions

What would make us change course?

  • "If [signal], we will revisit [bet]."
  • "If [competitor] ships [capability], we will [response]."
  • "If [metric] does not move by [date], we will [action]."
Step 8: Present the Memo

Format as a single, readable document:

# [Product / Team] Strategy — [Q/H/Year]

## Situation
[1 paragraph]

## Insight
[1 paragraph]

## Our Bets
1. [bet 1]
2. [bet 2]
3. [bet 3]

## What We're Not Doing
[2-4 explicit exclusions with rationale]

## Success Criteria
[North Star target + 2-3 milestones]

## Review Conditions
[2-3 signals that would trigger a strategy update]

The delivery wrapper uses the output kit format, but the memo body itself should be clean prose, not a CLI report.

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
