# Project conventions - instagram-skills

This file is for any Codex agent working on this repository. Read it before
making changes. Conventions here are mandatory unless the user asks otherwise.

## Versioning

- Single source of truth: `.codex-plugin/plugin.json`,
  `.agents/plugins/marketplace.json`, `.claude-plugin/plugin.json`, and
  `.claude-plugin/marketplace.json`. Plugin manifests must always match on
  package name and version; marketplace entries must point to the same package;
  author, license, homepage, and the public skill-bundle description must stay
  aligned.
- Keep `AGENTS.md` and `CLAUDE.md` aligned when changing shared project rules.
  Codex-specific workflow details belong here; Claude-specific details belong in
  `CLAUDE.md`.
- Codex marketplace install uses `.codex-marketplace/instagram-skills/`. Do not
  edit that generated package by hand. Update the root files first, then run
  `python3 scripts/sync_codex_marketplace.py`.
- **Default: bump the PATCH segment (3rd level, `0.0.X`).** This is the automatic
  behavior for every shippable commit, regardless of how large the diff feels.
  Skill renames, lib API breaks, new features: still PATCH by default.
- Only bump MINOR or MAJOR when **the user explicitly asks** for a higher rank
  ("this is minor", "make it 2.0", "bump major"). Do not promote on your own
  initiative even if semver textbook says so.
- After bumping, two steps are required:
  1. Tag the commit: `git tag -a v<X.Y.Z> -m "..."` + `git push origin v<X.Y.Z>`
  2. **Publish a GitHub Release** for the tag: `gh release create v<X.Y.Z> --title "v<X.Y.Z>" --notes "<changelog>" --latest`
  A tag alone does NOT update the README release badge. The shields.io badge
  reads from the Releases API, not from raw tags. Skipping step 2 leaves it stale.

## Commits

- Primary author **must** be Sergey: every `git commit` needs
  `--author="Sergey Bulaev <s@bulaev.org>"`. Verify with
  `git log -1 --format='%an <%ae>'` before pushing.
- Co-author trailers are fine when appropriate.
- Verify locally before push: build never breaks, no broken refs in `SKILL.md`,
  library smoke import passes.

## Skill bundle invariants

- **Exactly 8 skills.** Adding requires merging or splitting elsewhere to stay at
  8. The number is announced in plugin manifests and the README.
- **Frontmatter `description:` target <= 400 chars** (some bundle-heavy skills
  land slightly higher when their scope is genuinely broad; keep under 510).
  Always include a "Not for X (use Y)" disambiguation sentinel when a skill
  overlaps with a sibling.
- **No em dashes anywhere in `description:` fields.** Em dashes in body prose are
  allowed for table separators and list dividers only. No em dashes inside the
  literal fill-in lines of any hook skeleton.
- **Skill names are public surface.** Renaming a skill is a major version bump and
  requires updating: plugin manifests, marketplace entries, root `SKILL.md`
  bundle list, README skill table, and every `ig-<name>` cross-reference in
  sibling SKILL.md files.

## Voice rules + reference layout

- Canonical voice rules live at root `references/voice-rules.md`. Skill-local
  "Hard rules" sections must only contain skill-specific overrides and start
  with: `Global voice rules: see root SKILL.md Voice rules.`
- Other root-level references: `references/hook-formulas.md` (10 Instagram
  formulas), `references/algorithm-heuristics.md`, `references/hashtag-strategy.md`,
  and `references/media-workflow.md`.
- Skill-local references live in `skills/<skill>/references/`. Cite from the skill
  with bare `references/X.md`. Cite root from skills with `../../references/X.md`.
- `ig-humanizer` has `sub-skills/` for the folded-in post-audit workflow.

## Layer separation

- **Write layer (Publora):** `lib/publora_client.py`. Instagram requires media on
  every post, so the key method is `publish_media_post` (create draft, upload each
  image/video, then schedule). Lower-level: `create_post`, `get_upload_url`,
  `put_to_s3`, `update_post`, `delete_post`, and `list_connections` /
  `instagram_connections` (GET /platform-connections). Skills call
  `lib.publish(kind, draft_text, target_url, media=[...], ...)`. Real endpoints:
  `POST /create-post`, `POST /get-upload-url`, `PUT /update-post/:id`,
  `DELETE /delete-post/:id`, with `platforms: ["instagram-<id>"]` (array of
  STRING ids), header `x-publora-key`.
- **Media is mandatory.** Text-only Instagram posts fail at publish time. The
  writer skills produce the caption; the user supplies the media. `publish()`
  only auto-posts on the Publora tier when `media` file paths are provided;
  otherwise it returns the copy-paste caption block with a media reminder.
- **No read layer ships by default.** `ig-hook-extractor` asks the user to paste
  the caption (and slide or Reel hook). Any future Instagram-read actor stays
  gated behind `APIFY_TOKEN` with a paste fallback.
- Don't name competing third-party schedulers in committed files.

## Codex marketplace package

- Codex requires marketplace entries to point at a nested plugin directory. The
  root remains the Claude-facing source layout.
- `.agents/plugins/marketplace.json` points to `.codex-marketplace/instagram-skills`.
- `scripts/sync_codex_marketplace.py` copies the root Codex manifest, `SKILL.md`,
  `skills/`, `references/`, `lib/`, `scripts/`, `requirements.txt`, `.env.example`,
  and `LICENSE` into the hidden package.
- After editing any copied file, run the sync script before testing or committing.

## testing/ is gitignored

- `testing/` is the local scratch directory: API keys, sample responses,
  validation reports. Never write secrets above `testing/` (the rest of the repo
  is public). The `.gitignore` rule for `testing/` is load-bearing.

## Validation before push

Run from repo root:

```bash
python3 -c "from lib import publish, parse_instagram_url, PubloraClient; print('OK')"
python3 scripts/sync_codex_marketplace.py
ls skills/ | wc -l        # must equal 8
python3 -m json.tool .codex-plugin/plugin.json >/dev/null
python3 -m json.tool .agents/plugins/marketplace.json >/dev/null
python3 -m json.tool .claude-plugin/plugin.json >/dev/null
python3 -m json.tool .claude-plugin/marketplace.json >/dev/null
```

If any of these fail, do not push.
