ai-workflow-framework: Skill for Claude Code

.claude/skills/start-session/SKILL.md

start-session is a skill for Claude Code from satsilem/ai-workflow-framework. It costs 82 tokens per session (955 once invoked), scanned A, original, MIT.

A session-start guide that loads key project files before work begins. It checks files such as CLAUDE.md, SESSION.md, TODO.md, and an optional reference index.

In plain words
What is it for?
It helps orient the agent at the start of a project session by reading the main instructions, active tasks, important learnings, and recent session entries.
Why use it?
Without the project's instructions and recent history, an agent may miss constraints, open tasks, or lessons from earlier work.

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

start-session 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Start Session

The goal is to orient quickly — give enough context to work effectively without overwhelming with detail. Think of it as a smart handoff from the last session.

Step 1 — Check files exist

Look for these files in the current working directory:

  • CLAUDE.md
  • SESSION.md
  • TODO.md
  • .reference/INDEX.md (optional but recommended)

If any are missing, warn immediately:

⚠️ Missing: SESSION.md — no session history available
⚠️ Missing: TODO.md — no task list found

If CLAUDE.md is missing, note that the project may not be set up yet and suggest running the project-setup skill.

Step 2 — Read the files strategically

  • CLAUDE.md — read in full (it's the master reference, usually concise)
  • .reference/INDEX.md — if present, read in full; this is the evergreen lookup map
  • TODO.md — read strategically:
    • ## Open Tasks — read in full (this is the canonical active work list)
    • ## Done — skip by default unless needed for clarification
  • SESSION.md — read selectively:
    • KEY LEARNINGS section — read in full (critical gotchas, always relevant)
    • CHRONOLOGICAL LOG — read only the last 2-3 entries (recent = relevant)
    • Skip everything older — it's history, not context

SESSION.md can be hundreds of lines. Don't read it all — the gotchas and recent entries are what matter for orienting quickly.

Use .reference/ for stable operational/docs lookup context. Use .ai-notes/ only when a specific investigation timeline is needed.

Step 3 — Produce the session brief

Use this structure. Keep each section tight — no padding, no repetition.

## Session Ready — [Project Name]

**Project:** [What this project is + current status in 2-3 lines]

**Last session:** [What was done + any key decisions made — 2-3 lines]

**Key gotchas:**
- [Top 2-3 warnings from KEY LEARNINGS most relevant right now]
- [Only include ones that could actually affect today's work]

**Open tasks:**
1. [!] [Important task title]
  scope: ... | target: ... | owner: ... | next: ... | updated: YYYY-MM-DD
2. [!] [Next urgent task title]
  scope: ... | target: ... | owner: ... | next: ... | updated: YYYY-MM-DD
3. [ ] [Remaining open task title]
  scope: ... | target: ... | owner: ... | next: ... | updated: YYYY-MM-DD

**Suggested focus today:**
- [2-3 specific items Claude thinks deserve attention, based on context,
   recency, and what was left unfinished last session]

**Reference docs to use:**
- [0-3 relevant files from `.reference/INDEX.md` for likely lookup during this session]

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.
