cctap CLAUDE.md

cctap CLAUDE.md is an instructions file for coding agents from chipmates/cctap. It costs 828 tokens per session, scanned A, original, MIT.

Repository instructions for cctap, a terminal tool that tracks parallel Claude Code sessions and shows which one needs attention.

In plain words
What is it for?
They guide changes to cctap's hooks, local daemon, Unix-socket storage, state reducer, and session-navigation behavior.
Why use it?
They define safety and design rules so session hooks remain unobtrusive, local, dependency-free, and under human control.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

cctap CLAUDE.md 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 3d 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.

Guidance for Claude Code and any other coding agent working in this repository. Contribution guidelines are in CONTRIBUTING.md.

What this is

cctap is a terminal-native attention router for parallel Claude Code sessions. It watches sessions through hooks, keeps one state model in a small local daemon, renders a glyph strip, and jumps you to the session that needs you.

Hard rules

  • Zero runtime dependencies. package.json dependencies stays {} forever. Runtime imports are node:* builtins or relative paths, nothing else.
  • Hooks must never disturb Claude Code. The forwarder always exits 0, never writes to stdout, and self-terminates inside 100 ms. See invariants I1 to I3 in spec/CONTRACTS.md. On several hook events, stdout becomes model context and exit 2 blocks the action, so both are absolute.
  • Never inject input into a Claude session. Jumping there is the approve flow. The decision stays with the human.
  • Local only. A unix socket under ~/.cctap/, directory 0700, files 0600. No TCP, no telemetry, no network egress of any kind.
  • The state machine is a pure reducer. No clock reads, no I/O, no randomness. Time enters through an event timestamp or an explicit sweep call.
  • TypeScript strict, Node 22 or newer, pnpm.

The spec is normative

  • spec/CONTRACTS.md: socket protocol, wire shapes, invariants I1 to I19, test requirements.
  • spec/transitions.md: the state machine, single source of truth for the reducer.
  • spec/fixtures/*.json: acceptance fixtures, consumed verbatim by the test suite.

If code and spec disagree, the spec wins. Change the spec deliberately, in its own commit.

Test hygiene, not negotiable

  • Every test and every manual run sets CCTAP_DIR to a temp directory. Never the real ~/.cctap.
  • Anything touching Claude Code settings sets CCTAP_CLAUDE_SETTINGS. Never the real ~/.claude.
  • Every test file sets CCTAP_NOTIFY=off and CCTAP_NO_EXEC=1 at import time, and tempEnv() passes both to child processes. No test may fire a desktop banner, send an Apple event, or pop an Automation consent dialog.
  • tests/invariants.test.ts enforces the two rules above and will fail if they are weakened.
  • State machine changes need a row in tests/coverage.test.ts, which walks the whole event table.

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.
