Four Core Documents is an agent skill from indranilbanerjee/digital-marketing-pro. Produce Part 3 of the 12-Part engagement: the four strategic-spine documents across 61 steps — 3.1 Business & SBU Analysis, 3.2 Segmentation Framework, 3.3 Brand Positioning & Communications, 3.4 DMFlow — with --doc single-document runs, --view v2 re-runs, and a --combined executive stitch. Triggers on "/digital-marketing-pro:four-core-documents", "produce the four core documents", "run part 3 of the engagement", "generate the strategic spine", "re-run positioning as v2". Requires an initialised engagement with…
Its SKILL.md is about 4.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering Positioning and messaging. The repository describes itself as: An open-source AI marketing operating system for strategy, SEO, AEO/GEO, paid media, content, CRM, and analytics - grounded in brand context, human approval, and verifiable… The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 3343924. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBashGlobGrepFrom allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Four Core Documents loads about 4.1k tokens when it runs. Until then it costs about 165 tokens; SKILL.md has 1,375 words of instructions outside code blocks.
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.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Write, Edit, Bash, Glob, GrepAutomated 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.

.claude/skills/four-core-documents/SKILL.md (or your agent's skills folder).This skill produces Part 3 of the engagement methodology: the four documents that together define the brand at strategic depth. Every channel strategy, every creative brief, every piece of copy reads back to these.
Heavy skill. Grep before Read any referenced file, then Read only matched ranges with offset + limit. List the brand's workspace at ~/.claude-marketing/brands/{slug}/ (or $CLAUDE_PLUGIN_DATA/digital-marketing-pro/brands/{slug}/ when that env var is set) before opening files. On re-invocation mid-session, skip files already in context.
Specification: four-core-documents-spec.md — the exact 61 steps across the four documents.
Engagement context: engagement-flow-methodology.md — where Part 3 fits in the 12-Part flow.
Before running this skill, verify:
~/.claude-marketing/brands/{brand-slug}/profile.json. If not, run /digital-marketing-pro:brand-setup first._engagement.json present. If not, run /digital-marketing-pro:engagement start first.If any pre-condition fails, do NOT produce output. Instead, instruct the user on what to run first.
/digital-marketing-pro:four-core-documents <brand-slug> <engagement-id>Produces 3.1, 3.2, 3.3, 3.4 in sequence. Actual time varies with engagement complexity.
/digital-marketing-pro:four-core-documents <brand-slug> <engagement-id> --doc 3.1Produces just the specified document. Useful for re-runs (Part 6) or when one doc needs to be redone independently.
/digital-marketing-pro:four-core-documents <brand-slug> <engagement-id> --view v2 --doc "3.1,3.3"Produces v2 versions of the specified documents. --doc takes a single id (3.1) or a comma-separated list ("3.1,3.3"). Used during Part 6 after the Decision Matrix has triggered re-runs. (The canonical flags are --doc, --view v2, and --combined — there is no --docs.)
/digital-marketing-pro:four-core-documents <brand-slug> <engagement-id> --combinedStitches all four canonical core documents (latest version of each) into a single executive-reference file with master TOC, master assumptions table, and master source index. Produced only when an executive audience needs a single-file read.
The four documents are produced in sequence because each builds on the prior:
When running re-runs, only the affected documents are regenerated. Other documents remain at their current version.
Read the spec section for 3.1 in four-core-documents-spec.md. The 18 steps are:
Inputs:
part-01-client-inputs/stone-facts.json — ground-truth factspart-02-external-research/ — unbiased external research (industry data, market context)~/.claude-marketing/brands/{slug}/profile.jsonOutput:

(For v2 re-runs: same path but in v2/ instead of v1/)

Steps 10–13 are skipped for B2C engagements. The skill detects B2B vs B2C from the brand profile's business_model.type field.

The 9 steps:
Inputs:
Output:
engagements/{id}/part-03-four-core-documents/v1/3.4-dmflow.md
Each document is produced as a single file containing all its steps. If a document cannot be completed in one turn due to output limits:
There is no hidden continuation state — the skill does not persist a cut-off pointer. The partial file already saved to disk is the only record. If output is interrupted mid-document, re-run the document: read the saved partial as context and continue appending the remaining steps to the same file. For a run interrupted at the engagement level, resume from the part's last checkpoint artifact via /digital-marketing-pro:resume. The saved file is always the source of truth.
Once all four documents are produced (or after each individually):
_engagement.jsonWhen invoked with --view v2, the skill:

- Section Y: ...v2/{doc-name}.md (the v1 file remains untouched)_engagement.json via engagement-state.py bump-versionUser: Produce the four core documents for the Acme engagement.

Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add indranilbanerjee/digital-marketing-pro --skill four-core-documents -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/four-core-documents, .gemini/skills/four-core-documents, .github/skills/four-core-documents and .opencode/skills/four-core-documents in your project.
SKILL.md names no scripts, command-line tools or credentials: Four Core Documents is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Glob, Grep.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Four Core Documents is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 4.1k tokens (SKILL.md is roughly 16k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
