What it does
Prime Context is an agent skill from swingerman/engineer. Use before starting pipeline work on a Ready feature the agent hasn't worked yet. Triggers — "/engineer.prime-context", "prime context", "load context before we start", "get up to speed on feature X".
Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: Disciplined Agentic Engineering — a methodology kit for Claude Code: acceptance-test-first specs, explicit checkpoints, and autonomy you can actually leave running. The engineer… The licence is MIT.
When your agent uses it
- — /engineer.prime-context
- Load context before we start
- Get up to speed on feature X
Example prompts
- “t worked yet. Triggers —”
- “prime context”
- “load context before we start”
- “/prime-context”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Resolve + locate — resolve the methodology root + manifest via ${CLAUDE_PLUGIN_ROOT}/scripts/dae_resolve.py (see references/resolving.md)…
- Silent batch load — without narrating: feature.md, CHARTER.md, manifest.yml, prior handoffs/ (especially the originating *-discuss.md)…
- Orient — give a concise summary: outcome, scope, autonomy level (+ charter cap), key prior decisions, related code, relevant ADRs.
- One prompt — ask exactly one question: anything else to load? If the user names a new code pointer, load it and offer to add it to…
- Breadcrumb handoff — emit a tiny handoff recording what was loaded.
What it can do on your machine
Read from SKILL.md and the folder at commit 32947eb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
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
Links to these hosts (documentation or services it may open):
notion.so
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
Prime Context loads about 865 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 393 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.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
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.

- Use before starting pipeline work on a Ready feature the agent hasn't worked yet. Triggers — "/engineer.prime-context", "prime context", "load context before we start", "get up to speed on feature X".
prime-context
Load working memory before pipeline work on a Ready feature — the convergent counterpart to discuss. Forked from superpowers:brainstorming but inverted: no exploration, just loading and orienting. Produces no artifact.
When to use
A prep step (not a checkpoint) between feature-init and discover-acs, on any feature the agent hasn't already worked this session.
Skip when: the agent just created the feature this session (context already warm). Not for: exploring whether a feature is worth doing (discuss).
Workflow
- Resolve + locate — resolve the methodology root + manifest via
${CLAUDE_PLUGIN_ROOT}/scripts/dae_resolve.py(seereferences/resolving.md); locate the feature (slug arg or branch name). Reject if no folder / nofeature.md. Layout disambiguation: if the project has BOTH afeatures/NNN-*/and aspecs/NNN-*/tree (a speckit migration in progress), state which holds this feature's artifacts; and if more than one acceptance-IR convention is present (features/NNN/.build/spec.jsonvs anacceptance-pipeline/ir/per-GWT layout), name the one this feature uses — so the load doesn't rediscover the split ad-hoc. (speckit-consolidateunifies it.) - Silent batch load — without narrating:
feature.md,CHARTER.md,manifest.yml, priorhandoffs/(especially the originating*-discuss.md), and the files named infeature.md's "Related code / design pointers". When loading those code pointers, prefer LSP —documentSymbolfor file shape,hoverfor signatures/types,workspaceSymbolto pull in the symbols they reference — over reading whole files blind, when an LSP MCP capability is available; fall back to grep + Read otherwise. See${CLAUDE_PLUGIN_ROOT}/references/code-lookup.md. - Orient — give a concise summary: outcome, scope, autonomy level (+ charter cap), key prior decisions, related code, relevant ADRs.
- One prompt — ask exactly one question: anything else to load? If the user names a new code pointer, load it and offer to add it to
feature.md. Then stop — prime-context orients, it does not interview. - Breadcrumb handoff — emit a tiny handoff recording what was loaded.
Show full SKILL.md (101 more words)Show less
Re-invocation re-loads fresh (no incremental diffing).
Handoff
Emit per ${CLAUDE_PLUGIN_ROOT}/references/handoff-summary.md. checkpoint: null; artifacts: []; human_action_needed: no; recommended_next: "/engineer.discover-acs".
Always emit a breadcrumb. Earlier versions produced no handoff because prime-context creates no artifact. Users expect a breadcrumb after every skill invocation (distbute Jun 4: "emit the handoff") — surprising them with "no artifact by design" breaks the agentic-summary contract. The breadcrumb records: which feature was primed, what files were loaded, any new pointer added to feature.md, and the next recommended skill. Body can be one paragraph — frontmatter is the load-bearing part for progress-log propagation.
